Description

  The present invention relates to a processing apparatus for paper sheets such as securities, and more particularly to a paper sheet processing apparatus that performs transport monitoring with a plurality of CPUs (Central Processing Units) when a transport path is long.

  A paper sheet processing apparatus for processing paper sheets such as securities is arranged at a predetermined pitch by a take-out device from a bundle of paper sheets (for example, 1000 sheets) that are input in a batch according to a processing unit. Each sheet is taken out and conveyed, and the type of the sheet (ticket type), the conveyance direction, and the quality of the correct / damaged / excluded ticket are determined by the detection device.

  The conveyance control unit controls the sorting gate arranged in the conveyance path based on the determination result of the paper sheet determination, and conveys it to the conveyance destination determined for each paper sheet. The paper sheets thus transported are stacked by a stacking device disposed at the end of each sorting transport path. In this stacking apparatus, an impeller stacking apparatus is used as a stacking method while absorbing the transport speed of paper sheets transported at high speed.

  The stacking device takes in paper sheets taken from the transport path and stacks them in a temporary stacking box. When the number of sheets stacked in this way reaches a predetermined number (for example, 100 sheets), the apparatus binds with a binding band such as a paper band to form a bundle of 100 sheets.

  Since a plurality of paper sheets exist on the transport path and are transported at high speed, each paper sheet is transmitted together with transport destination information set by the determination result of the detection device for each paper sheet (also referred to as shift processing). That is, each time a paper sheet passes through a conveyance monitoring sensor (also referred to as a sit sensor) arranged on the conveyance path, the conveyance destination information of the paper sheet is also conveyed along with the paper sheet as an attribute of the paper sheet. As a result, when the paper sheet is detected by the shift sensor, the transport destination information that is the attribute of the paper sheet is determined, and the sorting gate is driven based on the transport destination information to guide the stack to the stacking device. It is burned.

  As is apparent from the above description, the paper sheet is accumulated in the final accumulation device if only its destination information is transmitted by the shift process. As described above, a plurality of paper sheets are transported at high speed on the transport path, and immediacy is necessary to manage the transport destination information of each paper sheet. It was. In addition, a method has been used in which only the minimum necessary items are managed in the shift process because of the need for immediacy.

  However, due to the recent increase in the size of the system and the need for dealing with a plurality of ticket types, it is necessary to perform the shift processing with a plurality of CPUs, and the method has been studied. However, only the transport destination information has been managed as information managed in the shift process. In addition, the banknote depositing / withdrawing apparatus which memorize | stores how many banknotes of which denomination was accumulated in which site | part is known (for example, refer patent document 1).

JP-A-6-162324 (Page 7-8, FIG. 2)

  The stacking apparatus does not require ticket type information for each paper sheet because the sorting gate disposed upstream in the transport direction of the stacking apparatus is classified by the transport destination information by the shift process. Therefore, for example, the correct ticket determined as the first ticket type is accumulated in the correct ticket stacking device of the second ticket type, and the correct ticket determined as the correct ticket of the second ticket type is accumulated in the first ticket type. There is a problem in that even when the devices are integrated in the apparatus, there is a case where the normal processing is performed without causing a change in the number of stacked sheets in each of the stacking devices.

  In addition, since the detection of these conveyance monitoring sensors requires immediacy, conventionally, the detection is often performed by one CPU and the shift process is performed. However, with the recent increase in the size of the paper sheet processing apparatus, the conveyance monitoring is performed. The number of sensors has increased, and it has become impossible to detect and shift processing with a single CPU, and shift processing of a conveyance monitoring sensor has been started with a plurality of CPUs.

  Conventionally, when performing the shift processing of the conveyance monitoring sensors by the plurality of CPUs, only the information on the final conveyance destination of the paper sheet is used as an attribute. Therefore, the information on the stacking apparatus that can manage and store the paper sheet on the conveyance path is When there is a discrepancy between the number of inserted sheets and the number of stacked sheets, there is a problem that a retrospective survey cannot be performed based on the number of stacked sheets for each ticket type.

  In addition, the stacking device cannot manage and store information on ticket types, so it cannot know the ticket types that are frequently transported during maintenance, and cannot perform optimal maintenance according to the ticket type. there were.

  Furthermore, the final number check by the machine at the end of the paper sheet processing is only based on the number of stacked sheets, and the ticket type information cannot be used for the number check.

  In addition, since the apparatus described in Patent Document 1 does not use the function of shifting the ticket type information, it has a drawback that it cannot be applied to a large apparatus having divided conveyance paths.

  Therefore, the present invention has been made to solve the above-described problem, even when the apparatus is large, the transport path is long, and the transport monitoring sensor is monitored by a plurality of CPUs. Paper capable of preventing occurrence of paper sheets and improving maintainability by shifting the ticket type information together with the transport destination information of the paper sheets as an attribute of the paper sheets being transported An object is to provide a leaf processing apparatus.

  The sheet processing apparatus 100 picks up and conveys one sheet at a time in order from the uppermost sheet P of the sheet bundle (for example, 1000 sheets) Ps input in a batch according to the processing unit, and detects it. This is a paper sheet processing apparatus that discriminates the paper sheet P by the apparatus 6 and performs sorting processing such as stacking and sealing of the paper sheet based on the discrimination result.

  In the present embodiment, a case where the module is composed of three modules and each module is composed of a module M1 (first module), a module M2 (second module), and a module M3 (third module) will be described. To do.

  In this embodiment, when the conveyance monitoring sensor is divided into a plurality of areas, the area is divided in accordance with the above-mentioned module division from the viewpoint of ease of manufacturing and assembling of the apparatus. In the present embodiment, the division is made in this way, but the module division and the area division do not always coincide with each other depending on the scale of the paper sheet processing apparatus. That is, there are configurations in which two areas exist in one module, and one area may be divided into two modules. In other words, the area is limited by the processing speed of the CPU, but the module is determined by the restrictions that come from manufacturing and assembly. In this embodiment, for the sake of simplicity, the case where the area and the module coincide with each other will be described.

  The module M1 includes a supply unit 1, an extraction rotor (extraction means) 2, a conveyance path (conveyance means) 3, a detection device (detection means) 6, an exclusion ticket accumulating device 16, and conveyance monitoring sensors PC11 to PC15 (first conveyance). A monitoring sensor) and a distribution gate (distribution means) G11 are provided. These are controlled by the M1 control CPU.

  The sheet bundle Ps (for example, 1000 sheets) supplied to the supply unit 1 is placed on the backup plate 1A. The backup plate 1 </ b> A is driven by a drive motor (not shown) to raise the uppermost sheet P placed on the backup plate 1 </ b> A to the take-out position of the take-out rotor 2.

  When the uppermost paper sheet P rises to the take-out position, the uppermost paper sheet P is detected by a take-out position sensor (not shown), and from the uppermost paper sheet P every time the take-out rotor 2 makes one rotation. One by one is taken out to the conveyance path 3. Accordingly, the taken paper sheets P are taken out to the transport path 3 at substantially regular intervals. The position of the backup plate 1A is controlled by the drive motor of the backup plate 1A and the take-out position detection sensor so that the uppermost sheet P is at the take-out position.

  The paper sheet P taken out by the take-out rotor 2 is detected by the detection device 6 for the type and quality (physical characteristics, shape, damage, etc.) of the paper sheet P, and a normal ticket (correct ticket) or a defective ticket is detected. (Slipper) and non-discriminated tickets such as counterfeit, heterogeneous, and indistinguishable tickets.

  As a result of this discrimination, the rejected tickets classified into counterfeit tickets, heterogeneous tickets, and indistinguishable tickets are accumulated in the reject ticket accumulating device 16.

  The module M2 accumulates and seals the distribution gates G21 and G22 that distribute the transport destination of the paper sheets based on the detection result of the detection device 6 and the paper sheets distributed by the distribution gates G21 and G22. -A sealing device is provided. In the present embodiment, the first ticket type stacking / sealing devices 21 and 22 that stack paper sheets determined to be the first ticket type based on the detection result correspond to this.

  As a result of the determination by the detection device 6, the paper sheet P determined to be a genuine note (real paper sheet) consisting of a genuine note or a damaged note is distributed to the left side by the distribution gate G11, and the counterfeit ticket Paper sheets determined as indistinguishable tickets are distributed to the right side by the distribution gate G11.

  When the paper sheet P sorted by the sorting gate G11 is the first ticket type, it is further transported to the stacking / sealing device 21 by the sorting gate G21, and is collected and accumulated in the temporary stacking box. The 100 sheets of paper sheets P that have reached 100 sheets are delivered to the sealing device and sealed to form a bundle of 100 sheets (a bundle of 100 genuine tickets).

  When the number of paper sheets stacked in the temporary stacking unit of the stacking / sealing device 21 reaches 100 sheets, the first bill of the first bill type transported continuously is transported to the stacking / sealing device 22. The sorting gates G21 and G22 are driven. In this way, 100 sheets of paper sheets accumulated in the temporary stacking unit 21 of the stacking / sealing device while the correct ticket of the first ticket type is being stacked in the temporary stacking unit of the stacking / sealing device 22 Sealing is performed by the sealing device of the device 21 to generate a bundle of 100 sheets.

  When the number of paper sheets accumulated in the temporary stacker of the stacking / sealing device 22 reaches 100 sheets, the continuous paper sheets are stacked in the temporary stacker of the stacking / sealing device 21, and Needless to say, it is sealed with a sealing device.

  When the detection device 6 determines that the ticket type is the second ticket type, the same processing as that performed by the stacking / sealing devices 21 and 22 is performed by the stacking / sealing devices 31 and 32.

  The module M3 is provided with second bill type stacking / sealing devices 31 and 32 for stacking paper sheets determined as the second ticket type by the detection device 6. Further, sorting gates G31 and G32 and conveyance monitoring sensors PC31 to PC36 are provided in association with the second bill type stacking and sealing devices 31 and 32.

  Further, the paper sheet that is determined as a non-returnable ticket (paper sheet that cannot be recirculated) by the detection device 6 is conveyed to the cutting device 34.

  The cutting device 34 is provided with two sets of a first cutting blade 34A configured by incorporating a plurality of disk-shaped blades on a rotating shaft and a second cutting blade 34B configured similarly. The first and second cutting blades 34A and 34B rotate while being in contact with each other, and can be cut.

  FIG. 2 is a control block diagram for explaining the control of the sheet processing apparatus 100 by a plurality of CPUs according to the first embodiment of the present invention.

  The module M1 is provided with an M1 control CPU 10 that controls the entire module M1 and a detection CPU 6A that constitutes the detection device 6, and is connected to a LAN (Local Area Network) 50.

  The M1 control CPU 10 is connected to the supply unit 1, the conveyance monitoring sensors PC11 to PC15, the sorting gate G11, and a conveyance motor (not shown), and is controlled by the M1 control CPU 10.

  The module M2 is provided with an M2 control CPU 20 that controls the entire module M2, and is connected to the LAN 50.

  The M2 control CPU 20 is connected to the stacking / sealing devices 21 and 22, the conveyance monitoring sensors PC21 to PC25, the distribution gates G21 and G22, and a conveyance motor (not shown), and is controlled by the M2 control CPU 20.

  The module M3 includes an M3 control CPU 30 that controls the entire module M3 and is connected to the LAN 50.

  The M3 control CPU 30 is connected to stacking / sealing devices 31 and 32, conveyance monitoring sensors PC31 to PC36, sorting gates G31 and G32, a conveyance motor (not shown), and a cutting device 34, and controlled by the M3 control CPU 30. .

  As described above, the M1 control CPU 10, the M2 control CPU 20, the M3 control CPU 30 and the detection CPU 6A are connected by the in-vehicle LAN.

  The M2 control CPU 20 and the M3 control CPU 30 are connected to the maintenance CPU 120 via the USB interface. With this connection, it is possible to extract storage information relating to the accumulation held by the M2 control CPU 20 and the M3 control CPU 30.

  Next, the conveyance monitoring process of the paper sheet P by the conveyance monitoring sensor of the present embodiment will be described.

  When a bundle of 1000 sheets Ps is collectively supplied to the backup plate 1A of the supply unit 1 and extraction is started, the backup plate 1A is raised and the sheet P is conveyed one by one from the extraction rotor 2 to the transport path 3. To be taken out. The taken paper sheet P is conveyed by the above-described method and detected by the detection device 6. This is the same as described above until the bundle of 100 sheets is formed according to the detection result of the detection device 6. An example of the conveyance monitoring process of the paper sheet processing apparatus 100 configured as described above will be described with reference to FIGS. 3 and 4 shown below.

  FIG. 3 is a flowchart for explaining the conveyance monitoring process of the module M1 constituting the paper sheet processing apparatus 100. When the paper sheet P is taken out by the take-out rotor 2, it is detected by a conveyance monitoring sensor (hereinafter referred to as a sensor) PC11 (S1). The detected paper sheet P is detected by the detection device 6, and the arrival times T11 and 12 from the sensor PC11 to the sensor PC12 are monitored (S2). This arrival time means a passage time during which the paper sheet P is conveyed and passes between the sensor PC11 and the sensor PC12.

  Therefore, the passage time measuring means for the arrival times T11 and 12 counts the time from when the sensor PC11 becomes dark until the sensor PC12 becomes dark every predetermined time (for example, 200 μs). This count can be measured using a timer interrupt of the M1 control CPU that manages the module M1. Alternatively, it can be measured by a hardware timer (not shown) provided outside managed by the M1 control CPU.

  The passage time measured by the passage time measuring means described above is judged whether the passage time is good or bad by the comparison / determination means shown in the following equation (1). If the result of the determination of the following expression (1) is within the specified value, it is determined to be normal (Yes in S4).

(T11 · 12−ΔT) ≦ T11 · 12 ≧ (T11 · 12 + ΔT) (1)
T11 · 12: Arrival time ΔT between sensor PC11 and sensor PC12: allowable value On the other hand, when arrival time T11 · 12 exceeds the specified value shown in the above equation (1) (No in S3), it is determined that the ticket is jammed. (S14).

  In step S4, when the paper sheet P is detected by the sensor PC 12 (Yes in S4), the arrival time T12 · 13 until the sensor PC 12 reaches the sensor PC 13 is monitored (S5). This arrival time T12 · 13 is confirmed in the same manner as the above equation (1), and if it is within the specified value, it is determined to be normal (Yes in S7).

  On the other hand, when the arrival times T12 and 13 are confirmed in the same manner as in the above equation (1) and exceed the specified value (No in S6), it is determined that the ticket is jammed (S14).

  Similarly, when the arrival time T13 · 14 (S8) until reaching the sensor PC 14 from the sensor PC 13 and the result of determination by the detection device 6 for the paper sheet P is a rejection ticket, the arrival time from the sensor PC 13 to the sensor PC 15 (S11) is also monitored.

  If the result of the confirmation is within the specified value as above, it is determined to be normal (Yes in S9 or Yes in S12), and if it exceeds the specified value, it is determined that the ticket is jammed (No in S9 or S12). No).

  FIG. 4 is a flowchart for explaining the processing of the detection device 6 arranged in the module M1 constituting the paper sheet processing apparatus 100. This process is processed by the detection CPU 6A.

  This detection process is processed by the detection CPU 6A in parallel with the conveyance monitoring process of the module M1 being processed by the MI control CPU 10.

  The detection device 6 includes a plurality of detection units such as a shape detection unit, a reflected light detection unit, a transmitted light detection unit, a magnetic detection unit, a fluorescence detection unit, and a thickness detection unit. The detection results of these detection units are combined. Paper sheet ticket type discrimination, conveyance direction discrimination, authenticity discrimination, and damage discrimination are performed.

  First, the authenticity (genuine or fake) of the paper sheet detected by each detection unit described above is determined (S40). Authenticity discrimination mainly detects physical characteristics of paper sheets as a medium to be detected.

  As a result of the true / false discrimination, if it is determined to be a genuine note (S40 true note), it is determined whether or not the discriminated sheet is the first note type that is the applicable note type of this embodiment (S41).

  As a result of the determination, in the case of the first ticket type, it is determined whether it is a correct ticket or a damaged ticket (S42). If it is determined that the ticket is a correct ticket (S42), the ticket type information is transmitted to the M1 control CPU 10 that the ticket type information is the first ticket type (S43).

  In step S42, in the case of a non-performing ticket (the non-slip ticket in S42), the M1 control CPU 10 is transmitted to the M1 control CPU 10 that the ticket type information is a first type ticket.

  Next, in step S41, if it is not the first ticket type (No in S41), it is determined whether it is the second ticket type (S44). As a result of the determination, if it is the second ticket type (Yes in S44), it is determined whether it is a correct ticket or a damaged ticket (S45). As a result of this determination, in the case of a correct ticket (S45), the fact that the ticket type information is a correct ticket of the second ticket type is transmitted to the M1 control CPU 10 (S46).

  Next, in the case of a non-conformity ticket as a result of the determination in step S42 (non-conformity ticket in step S42) or in the case of a non-conformity ticket as a result of determination in step S45 (non-conformity ticket in step S45), the ticket type information is a non-use ticket for each type of ticket. This is transmitted to the M1 control CP 10 (S47).

  Next, in the authenticity determination in step S40, if the detected paper sheet is clearly determined to be a fake ticket ("false ticket / indistinguishable ticket" in S40), or it is determined that it is not the second ticket type in step S44. If it has been made (No in S44), it transmits to the M1 control CPU 10 that the ticket type information is “fake ticket / indistinguishable ticket” (S48).

  The M1 control CPU 10 receives the determination result by the detection device 6, and sets the accumulation location as the transport destination of the paper based on the result.

  That is, the M1 control CPU 10 switches the sorting gate G11 based on the determination result. Accordingly, the sorting gate G11 is switched so that the paper sheet P determined to be a genuine note or a damaged note is conveyed to the module M2 or the module M3 side. On the other hand, the paper sheet determined as “fake ticket / indistinguishable ticket” is handled as a rejection ticket, and the sorting gate G11 is switched so as to be transported to the rejection ticket stacking device 16 side provided in the module M1.

  FIG. 5 is a flowchart for explaining the conveyance monitoring process of the module M2 constituting the paper sheet processing apparatus 100. In the module M2, stacking / sealing devices 21 and 22 for stacking and sealing the first bill of the first bill type are arranged. In the module M3, the stacking / sealing devices 31 and 32 for stacking and sealing the right bill of the second bill type are arranged, but since the basic operation is common, the stacking / sealing device 21, The conveyance monitoring process 22 will be described, and the description of the common parts of the stacking / sealing devices 31 and 32 will be omitted.

  In this embodiment, the M1 control CPU 10 of the module M1 and the control CPU 20 of the module M2 are connected by the LAN 50, and the ticket type information based on the detection result of the detection device 6 in the module M1, the accumulated location information, and the ticket length by the sensor PC 14 Information is notified from the M1 control CPU 10 to the M2 control CPU 20 of the module M2 through the LAN 50 (S20). Based on this information, the conveyance monitoring process by a plurality of CPUs will be described.

  The paper sheet P conveyed to the module M2 is detected by the sensor PC 21 (S21).

  The M2 control CPU 20 controls the sorting gate based on the ticket type information and the stacking location information received from the M1 control CPU 10, and transports the paper sheets to the stacking / sealing device set for each ticket type (sorting). Transport means). For example, when the ticket type determined by the detection device 6 is the first ticket type correct ticket, the distribution gate G21 is controlled and conveyed to the stacking / sealing device 21. That is, each time a paper sheet is transported from the transport upstream to the transport downstream while being detected by the transport monitoring sensor, the sheet type and stacking location information of the paper sheet are transported together as attributes (shift processing). Conventionally, only the stacking location information is shifted, but the present invention is characterized in that the ticket type and the stacking location information are shifted.

  This shift processing is also performed when a paper sheet is conveyed from the module M1 to the module M2, and when a module M3 paper sheet is conveyed from the module M2 described later. As a result of this shift processing, even if the stacking location is different for each type of paper sheet, stacking on each stacking / sealing device becomes possible.

  As a result, the paper sheets conveyed to the stacking / sealing device 21 are added and held as the number of stacked sheets of the first bill type when the passage is detected by the sensor PC 22. That is, the number of paper sheets actually conveyed to the stacking / sealing device of the first ticket type is counted (count 1).

  The count result (count 1) is transmitted from the M2 control CPU 20 to the M1 control CPU 10 via the LAN 50.

  Further, the M1 control CPU counts the number of sheets to be stacked on the stacking / sealing device 21 based on the sheet type information of the sheets (count 2).

  Next, the M1 control CPU 10 checks whether the count 1 and the count 2 received from the M2 control CPU match (matching means). This verification is performed by verifying that the stacking location information is originally set based on the ticket type information determined by the detection device 6, and that the paper sheet is conveyed to the stacking device based on the stacking information. This is because it is possible to prevent the paper sheets described in the above problem from entering. Further, by performing this collation, even when the transport destinations of the plurality of paper sheets between the detection device 6 and the stacking / sealing device are different from each other, the shift processing of the paper sheets is reliably performed. This is because it will be confirmed.

  In addition, although the case where the paper sheets conveyed to the stacking / sealing apparatus are detected by the sensor PC 22 has been described, the present invention is not limited to this, and it is detected that the paper sheets are taken into the impeller 21A. Although there is a method of detecting that the paper sheet is actually taken into the impeller by a sensor (not shown), the gist of the present invention is not related to a method of detecting the paper sheet accumulated on the blade 21A. Therefore, the detailed description is abbreviate | omitted.

  Further, in response to the sensor PC21 becoming dark, measurement of the bill length by the sensor PC21 is started. Specifically, the time during which the sensor PC 21 is dark is counted with a predetermined clock (for example, a clock having a period of 200 μs) (S22).

  In addition, the arrival times T21 and T22 from the sensor PC21 to the sensor PC22 are monitored (S24). As a result of this monitoring, the arrival times T21 and 22 are confirmed in the same manner as in the above equation (1), and are determined to be normal if they are within the specified values (Yes in S25).

  On the other hand, when the arrival times T21 and 22 exceed the specified value (No in S25), it is determined that the ticket is jammed (S26).

  In step S23, when the brightness of the sensor PC21 is detected (No in S23), the bill length measurement by the sensor PC21 is stopped, and the bill length by the sensor PC21 is determined from the time when the paper sheet P passes the sensor PC21. It is measured (S28). Whether or not the ticket length measured in this way and the ticket length notified from the M1 control CPU 10 are the same length is judged (S29).

  At this time, the bill length by the PC 14 which is the most downstream conveyance monitoring sensor of the conveyance monitoring sensor in the module M1 immediately upstream of conveyance is used. This is because, if the length measurement result by the conveyance monitoring sensor in the vicinity of the junction point of different modules is the same, it becomes a condition for allowing the conveyance path to be regarded as continuous. That is, the ticket length information transmitted from the M1 control CPU 10 which is the CPU arranged in the module located upstream is compared with the ticket length information by the ticket length measuring means in the module M2, and the comparison determination result is obtained. Based on this, the lack of the ticket is determined. Therefore, in this embodiment, the ticket lengths of the sensor PC 14 and the sensor PC 21 arranged in the vicinity of the junction point between the module M1 and the module M2 are compared and determined (S29, conveyance monitoring means).

  When determining the ticket length, if the ticket length by the sensor PC 14 is shorter than the ticket length by the sensor PC 21 as a result of this comparison determination, it is determined that the ticket is missing (S30).

  As described above, according to the embodiment of the present invention, even when the apparatus is enlarged and the conveyance path becomes long, the module is divided within a range in which conveyance can be monitored by one CPU, and each module is connected to the LAN. A plurality of modules by measuring the length of the paper sheet P transported by the module located at the upper level of transport and transmitting the ticket length data of the paper sheet P to the next module as the ticket length information. Even when the paper sheet P is transported between them, the transport monitoring of the paper sheet P can be performed by a plurality of CPUs.

  In the above embodiment, when an additional ticket type is added, the module M2 can be added between the module M2 and the module M3. Since a CPU is mounted on each module, the ticket conveyance monitoring capability on the conveyance path is equivalent to that when no module M2 is added.

  Even in this case, since it is performed in the same manner as the transport control method in the M1 control CPU 10 and the M2 control CPU 20, the different parts will be described.

  The M3 control CPU 30 switches the sorting gates G11 to G32 on the basis of the ticket type information and the stacking location information transmitted from the M1 control CPU (first transport control means) 10 and transports them to the stacking / sealing device. The number of each ticket type conveyed to the stacking / sealing device is counted (count 3).

  The M3 control CPU 30 transmits the count 3 to the M1 control CPU 10.

  The M1 control CPU 10 checks whether or not the count 3 received from the M3 control CPU 30 matches the number of tickets for each ticket type transmitted to the M3 control CPU 30. If they match as a result of this collation, it indicates that the processing has been performed normally.

  As described above, when the module is expanded, the ticket type information and the accumulation location information are transmitted to the control CPU of each module via the LAN.

  The control CPU of each module transports the transported paper sheets to the stacking / sealing device of each module, counts the number of each ticket type actually transported to the stacking / sealing device, and transmits it to the M1 control CPU 10 To do.

  The M1 control CPU 10 checks whether the count (number of sheets) for each ticket type received from the control CPU of each module via the LAN matches the number of sheets transmitted to each module.

  As described above, according to the paper sheet processing apparatus of the present invention, even if the system is large and the conveyance monitoring is performed by a plurality of CPUs, the ticket type information and the accumulation location information of the detected paper sheets Is transmitted from the M1 control CPU to the M2 control CPU together with the conveyance monitoring sensor information, so that it is possible not only to obtain an effect equivalent to performing conveyance monitoring with one CPU, but also to collect the detected paper sheets. Since the ticket type information is transmitted as an attribute attached to the location information, it is possible to prevent occurrence of paper sheets accumulated at the stacking unit / sealing total position.
