Next, the operation of the multi-disk storage and selection performance device according to the present invention having such a configuration will be described with reference to the operation of the controller 11 shown in FIGS. 8 to 13.

When the power is turned on, a microprocessor (not shown) in the controller 11 initializes various flags and counters, and then starts a CD player presence determination routine. After the processing, a disk data reading routine is started. , A performance control routine, and a door open data exchange control routine. These four routines are repeated, and a music selection input routine is interrupted.

In the CD player presence determination routine, the controller
The microprocessor in 11 first determines whether or not the power-on operation flag _FW is 1 as shown in FIG. 8 (step 101). If F _W = 1, the processing of this routine has already been performed after power-on, so the processing of this routine is terminated. If F _W = 0, since the processing of this routine is not performed, the variable n is made equal to 1 (step
102), it is determined whether or not the door 89 is open (step 103). If the door 89 is closed, it is determined whether or not the n-th CD player 1 is mounted (step 104). That is, the communication line selector 10 selects the n-th CD player, and determines whether or not a predetermined confirmation voltage is supplied from the confirmation line. CD player 1 is the first CD player, C
The D player 2 is a second CD player, and the CD player 3 is a third CD player. Flag when specified confirmation voltage is supplied
CD (n) is set to 1 (step 105), and the TOC from each disc mounted on the magazine for the nth CD player is set.
(Table of Contents) A data read command signal is generated to command data reading (step 106). If the specified confirmation voltage is not supplied and the ground potential, the flag CD
(N) is reset to 0 (step 107). step 1
After execution of 06 or 107, 1 is added to the variable n (step 10).
8) It is determined whether the variable n is greater than 3 (step 109). If n ≦ 3, the routine proceeds to step 103, and if n> 3, the flag _FW is set to 1 (step 110), and the processing of this routine is terminated. The flag CD is processed by this routine.
Each content of (1), CD (2), and CD (3), that is, the presence or absence of the CD players 1 to 3 is set.

If at least one magazine is not mounted in the CD player, the generation of the predetermined confirmation voltage may be stopped to ensure safety, and the controller 11 may ignore the CD player.

When the TOC data read command signal is supplied to the CD players 1 to 3, the TO
C data is read by the pickup. The TOC data read for each of the CD players 1 to 3 is written to an internal RAM (not shown) for each of the CD players 1 to 3 together with a magazine number and a disk number. CD player 1 3 keep Upon completion of reading and writing the TOC data flag F ₂ indicating the data read ends and 1. The flag F ₂ is a flag that is formed in the internal controller of each 3 to no CD player 1 (not shown),
It is reset to 0 when the power is turned on and when one of the magazines is taken out for each CD player. Each of the CD players 1 to 3 is provided with a switch (not shown) for detecting the mounting for each magazine.

After the processing of the player presence determination routine, the microprocessor of the controller 11 executes a disk data reading routine. In the disk data reading routine,
As shown in FIG. 9, the variable n is set to 1 (step 12).
1) It is determined whether or not the data read end flag F (n) is equal to 1 (step 122). If F (n) = 0, it is determined whether or not the flag CD (n) is equal to 1 (step 123). If CD (n) = 0, the n-th player is not mounted, and the process immediately proceeds to step 126 described later. If CD (n) = 1, the flag F is sent from the nth CD player.
Flag F ₂ reads ₂ it is determined whether or not equal to 1 (step 124). That is, in the case of n = 1 is to determine whether or not the flag F ₂ reads a flag F ₂ from the CD player 1 is equal to 1. If F ₂ = 1, the magazine number, the disk number and the TOC data are read from the internal RAM of the nth CD player and written in the TOC data map of the RAM 20 (step 125). And the data reading end flag F (n)
Is set to 1 (step 126), and it is determined whether or not all the data reading end flags F (1), F (2) and F (3) have become equal to 1 (step 127). F (1)
If = F (2) = F (3) = 1, the TOC data has been read from the existing CD player, and this routine ends. Flags F (1), F (2) and F (3) are all 1
If not, it is determined whether or not a predetermined time has elapsed from the start of this routine processing (step 128). If the predetermined time has elapsed, it is considered that the TOC data cannot be read, and the routine ends. If the predetermined time has not elapsed, 1 is added to the variable n (step 129), and the variable n
Is greater than or equal to 3 (step 130).
If n ≦ 3, the process proceeds to step 122, and if n> 3, the process proceeds to step 121. Note that in step 122, F (n) = 1
If so, since the TOC data has already been read from the n-th CD player, the process proceeds to step 128. Also in step 124
If F ₂ = 0, since the TOC data has not been read in the nth CD player yet, the process proceeds to step 128.

A TOC data map is formed in the RAM 20 as shown in FIG. 14, and the TOC data TOC (1) to (6) is processed for each magazine by processing the above disk data reading routine.
Is written to the TOC data map. However, if the disk does not exist, the previous data at that storage location is erased.

Next, a music selection input routine that is interrupted will be described. In this music selection input routine, for example, it is determined whether or not a key operation has been performed as shown in FIG. 10 due to a fixed time interruption (step 141). When a key operation is performed, a key code corresponding to the operated key is sequentially held in an input buffer (not shown) from the keyboard 21 in the controller 11, and when read by the microprocessor, the holding position of the key code is shifted. The read key code is not retained. If money has not been collected, the operation of the numeric keypad is ignored, and the key code is not held in the buffer. If a key code is held in the above input buffer, read it (step 14
2) It is determined whether or not the operation is a ten-key operation based on the read keycode (step 143). In the case of a ten-key operation, a ten-key input routine (step 300) is processed. If no key code is held in the input buffer, the process returns to another routine.

In the ten-key input routine, the read key code is set as numeric data N (m) as shown in FIG. 11 (step 301). Here, m is a variable, and its initial value is 1 as described later. N (1) is the magazine number, N
(2) indicates the disk number, N (3) indicates the 10 digit of the track number, and N (4) indicates the 1 digit of the track number. Then, the numerical data N (m) and the variable m are supplied to the drive circuit 26 in order to display the value indicated by the numerical data N (m) on the performance music indicator 23b (step 302). The value of the variable m is the total number of musical pieces displayed.
Since the display position from the left side of 3b is shown, the drive circuit 24 drives the musical piece display meter 23b to display the value indicated by the numerical data N (m) at the position indicated by the variable m. Numeric data N
After supplying (m) and the variable m, it is determined whether or not data exists at a storage position in the TOC data map of the RAM 20 specified by the numeric data N (m) (step 30).
3). That is, if m = 1, it is determined whether or not data has been written to the storage location corresponding to the magazine number N (m). If m = 2, the disk number is N (1) in the magazine of the magazine number N (1). It is determined whether or not the disk indicated by 2) exists, and if m = 3,4, the disk number N
In the disk of (2), the 10 digit of the track number N (m) is N
In (3), it is determined whether or not there is a digit of 1 (N). If no data exists in the storage position in the TOC data map specified by the numerical data N (m), a display stop command is issued to the drive circuit 24 to stop the display of the numerical data N (m) (step 304), end this routine. If data exists at the storage position designated by the numerical data N (m), 1 is added to the variable m (step 30).
5) It is determined whether the variable m is greater than 4 (step 306). If m ≦ 4, this routine ends. m
If> 4, the four-digit number required to select a song has been entered by operating the numeric keypad, so that a 1000 digit value N (1),
A four-digit number consisting of a 100 digit value N (2), a 10 digit value N (3), and a 1 digit value N (4) is selected as song selection data S
(Y) (step 307), and the variable m is set to 1 (step 308). y is a variable that is set to an initial value 1 when the power is turned on, and indicates a writing order to the performance order list formed in the RAM 20. Next, 1 is added to the variable x to make the variable t equal to the added value (step 309).
The music selection data S (t) is read from the position indicated by the variable t in the performance order list in 20 (step 310), and it is determined whether or not the music selection data S (t) is equal to the music selection data S (y) (step 310). Step 311). The variable x indicates the current music piece number in the music order list. If S (t) ≠ S (y), 1 is added to the variable t (step 312), and it is determined whether or not the variable t has reached the variable y (step 313). t <
In the case of y, the process proceeds to step 310. If t ≧ y, the same music selection data as the currently input music selection data S (y) is not written in the performance order list as a song to be played, so the music selection data is placed at the position indicated by the variable y in the performance order list. Write S (y) (step 314). For example, magazine number N (1) is 3, disk number N (2)
Is 5, the track number N (3), that is, the track number
If the 10 digit is 0 and the track number N (4), that is, the 1 digit of the track number is 6, "3506" is written as the music selection data S (y). After writing the music selection data S (y), 1 is added to the variable y (step 315), and this routine ends. If S (t) = S (y), the same music selection data as the currently input music selection data S (y) has already been written in the performance order list as the music to be played, so the music selection data S (y) The process of this routine ends without writing. The performance order list includes, for example, a plurality of music selection data S (1), S
(2),... Are written in the performance order list, and when performing, the music selection data S (x) of the music indicated by the variable x is read and played as described later.

If the operation is not a ten-key operation in step 143, it is determined whether the operation is a clear key operation (step 143).
144). If the clear key is operated, 1 is subtracted from the variable m (step 145), and a display stop command is issued to the drive circuit 24 to stop the display of the numerical data N (m) (step 145).
146). Therefore, for example, if the clear key is operated when the ten key indicating the magazine number 3 is erroneously operated by the user, the "2" displayed on the performance music indicator 23b disappears and the magazine number can be input again by the ten key operation. State.

Menu rotation key when not clear key operation
It is determined whether or not the operation is 55 (step 150). If the menu rotation key 55 has been operated, it is determined whether or not the door 89 is open (step 151). This is determined by the output signal of the open / close sensor 25. If the door 89 is closed, the motor driving command generated to the drive circuit 24 (step 152), resets set only One door opening flag F _D 1 to 0 to the motor drive flag F _M (step 153) . The drive circuit 24 rotationally drives the motor 69 according to the motor drive command. The rotation of the motor 69 causes the rotation of the pulley 70 and the belt
71, a pulley 68, a worm gear 66, and a spur gear 65 to be transmitted to the triangular prism member 62.
6, and transmitted to the triangular prism member 61 via the pulley 72,
Further, the power is transmitted to the triangular prism member 63 via the pulley 74, the belt 77, and the pulley 75. Therefore, the triangular prism members 61 to 63
Rotate in the same direction, for example, clockwise at the same speed. When the triangular prism members 61 to 63 rotate by 120 degrees, the projection 79 reaches the position of the photo sensor 80, and the photo sensor 80
Generates a position detection signal. After performing step 153,
It is determined whether the triangular prism members 61 to 63 have rotated 120 degrees (step 154). If the position detection signal from the photo sensor 80 has occurred, the motor drive flag F _M is reset to 0 as a triangular prism member 61 to 63 has rotated 120 degrees (step 155), the motor drive stop command to the drive circuit 24 Occurs (step 156). Since the drive circuit 24 stops the rotation of the motor 69 in response to the motor drive stop command, the drive circuit 24 stops at the position where the triangular prism members 61 to 63 are rotated by 120 degrees.
As a result, a new music selection menu is displayed at the front. That is, every time the menu rotation key 55 is operated, the triangular prism members 61 to 63 are rotated 120 degrees and the displayed music selection menu changes. In the case of this embodiment, the music selection menu can be provided with 36 discs, 12 at a time.
You can display as many as. The drive circuit 24 controls the duty ratio of the motor 69, and gradually changes the duty ratio in response to the motor drive stop command to apply braking to the motor 69.
Stop the rotation of.

If not the operation of the menu rotation key 55 in step 150 the flag F _M is determined whether equal to one (step 157). If F _M = 1, the music selection menu is being changed while the motor 69 is being driven, and the routine proceeds to step 151, where it is determined whether or not the door 89 is open. This is to cope with a case where the door 89 is opened while the music selection menu is changing. In the case of the open state of the door 89 the flag F _D is determined whether equal to one (step 158). F _D = 0
If so, a performance stop command is issued to forcibly stop the performance if it is currently being performed (step 159). And sets 1 to the flag F _D (step 160), a triangular prism member 6
The process proceeds to step 156 to stop the rotation of 1 to 63, and issues a motor drive stop command to the drive circuit 24.
If F _D = 1, since the performance has already been stopped and the driving of the motor 69 has also been stopped, this routine ends. afterwards,
If the door 89 is closed, the process proceeds to step 152, so even if the triangular prism members 61 to 63 are stopped without rotating by 120 degrees, rotate again and rotate the music selection menu correctly facing the front. Stop.

Next, the performance control routine will be described. In the performance control routine, as shown in FIGS. 12 (a) and 12 (b), it is first determined whether or not the power has just been turned on (step 161). If it is not immediately after the power is turned on, it is determined whether music selection data is written at the x-th position in the performance order list (step 162). If the power has just been turned on, the variable x is set to 1 (step 163), and the process proceeds to step 162. The determination as to whether or not the music selection data has been written at the x-th position in the performance order list is made by detecting whether or not the writing number y of the music selection data has advanced to the x-th position at step 207. If no music selection data has been written at the x-th position in the performance order list, the processing of this routine ends. On the other hand, if music selection data is written at the x-th position in the performance order list, it is determined whether the search flag F _S , the play flag _FP, and the next music standby flag F _N are equal to 1 (steps 164 to 166). ). If F _S = 0, no CD player is performing a search operation, if F _P = 0, no CD player is performing a performance operation, and F _N =
If it is 0, there is no player in the standby (playing operation start waiting) state for the designated music to be played next.
The music selection data S (x) is read from the performance order list (step 167). A magazine discrimination subroutine for discriminating a magazine number from the read music selection data S (x) is executed (step 168). This subroutine obtains the value of 1000 digits of the music selection data S (x) as a magazine number M (x). For example, 0.001 is added to the music selection data S (x).
Multiply by It is determined whether the thus obtained magazine number M (x) is the magazine of any CD player (step 169). If the magazine number M (x) is 1 to 3, the magazine belongs to the first CD player 1 and the variable z is set to 1
(Step 170), and if the magazine number M (x) is 4 to 6, the magazine belongs to the second CD player 2 and the variable z is equal to 2 (Step 171), and the magazine number M (x) is 7 to If it is 9, it is a magazine belonging to the third CD player 3 and the variable z is made equal to 3 (step
172). Then, a signal including a search command is sent to the z-th CD player in a predetermined format together with music selection data S (x) (step 173), and a search flag F _S is set to 1 to indicate that a search operation is being performed (step 173). 174).

When the z-th CD player receives a search command together with music selection data S (x), an operation is performed according to the magazine number, disk number, and track number indicated by music selection data S (x). Here, assuming that the music selection data S (x) is a value represented by abcd, the magazine with the magazine number a is selected, the disk with the disk number b is selected from the magazine, and moved to the turntable. Then, the rotation drive of the disk is started, and the pickup moves to the track of the track number cd by the search operation. When the pickup is located on the track of the track number cd, the movement of the pickup stops and the apparatus enters a standby state. These operations are well known and will not be described in further detail. The zCD player play standby flag F ₃ 1 becomes the standby state
Set to.

Therefore, after execution of step 174, the controller 11
Play standby flag F ₃ of the CD player is determined not to have been set to 1 (step 175). Also step 1
If F _S = 1 at 64, the process immediately proceeds to step 175. If F ₃ = 1, since the search operation is completed by resetting the 0 the search flag F _S (step 176), sends a play command signal to the first zCD player (Step 17
7), 1 is set to the play flag F _P to indicate a playing (step 178). In the first zCD player, after resetting the play standby flag F ₃ to 0 in response to the play command signal to start the musical performance of the music of the track number cd. Left and right channel audio signals output from the z-th CD player are supplied to an amplifier 13 via an audio line selector 12.
And the speaker devices 14 and 15 are driven to output reproduced sound. When the playing operation of the music of the track number cd is completed controller of the zCD player put sets 1 in the play end flag F _4. During the performance, a music number, a disk number, and a track number relating to the performance music are displayed on the performance music indicator 23b.

Controller 11 after the execution of step 178, the play end flag F ₄ of the zCD player determines whether a 1 (step 180). If F _P = 1 in step 165, the process immediately proceeds to step 180. If F ₄ = 1,
Since music performance by the music selection data S (x) has been completed, respectively resets the play flag F _P and standby disable flag F _E to 0 (step 181), 1 to the variable x for performance by following the order of the music selection data After the addition (step 182), the processing of this routine ends.

If F ₄ = 0 In step 180, the zCD player because it is being played, the standby disable flag F _E is determined whether equal to one (step 185). In the case of F _E = 1, it is determined that z = r in step 194 described later, and the music of the music selection data written at the (x + 1) -th position in the performance order list is included in the disc mounted on the z-th CD player being played. Since the standby state cannot be set, the processing of this routine ends. If F _E = 0, it is determined whether or not music selection data has been written at the x + 1-th position in the performance order list (step 186). X + in the play order list
If the music selection data has not been written first, the processing of this routine ends. On the other hand, x +
If the music selection data to the first is written, the search flag F _S is determined whether equal to 1 (step 18
7). If F _S = 0, none of the CD players is in the search operation, so the music selection data S (x + 1) is read (step 188). A magazine discrimination subroutine for discriminating a magazine number from the read music selection data S (x + 1) is executed (step 189). And Magasin number M
It is determined whether (x + 1) is the magazine of any CD player (step 190). Steps 188, 189 and 190 are the same operations as steps 167, 168 and 169 described above. If the magazine number M (x + 1) is 1 to 3,
1) The magazine belonging to the CD player 1 and the variable r is made equal to 1 (step 191). If the magazine number M (x + 1) is 4 to 6, the magazine belongs to the second CD player 2 and the variable r is made equal to 2 (step 191). 192), if the magazine number M (x + 1) is 7 to 9, the third CD player 3
And the variable r is made equal to 3 (step 193).

After execution of step 191, 192 or 193, it is determined whether or not the variable z is equal to the variable r (step 194). If z = r, the music of the music selection data written to x + 1 th playing order list because it contains the disk mounted to the zCD player playing, and sets 1 to the standby disable flag F _E (step 195) End the processing of this routine.
On the other hand, if z ≠ r, the tune of the music selection data written at the (x + 1) th position in the performance order list is not included in the disc mounted on the zCD player being played, so that a predetermined format is given to the rth CD player. Sends a signal including a search command together with music selection data S (x + 1) (step 196), and sets 1 to a search flag F _S to indicate that a search operation is being performed (step 197). Thereafter, the controller 11 has play standby flag F ₃ of the rCD player determines whether set to 1 (step 198). If F _S = 1 in step 187, the process immediately proceeds to step 198. F
_{If 3} = 1, the search operation has been completed and the search flag F
The _S reset the 0, 1 is set to the next music standby flag F _N to indicate that it is a standby state for music selection data written to x + 1 -th (step
199), and ends the processing of this routine. If F ₃ = 0,
Since the search operation is being performed, the processing of this routine is immediately terminated.

If F _N = 1 in step 166, the variable z is made equal to the variable r because there is a player in the standby state for the next tune to be played (step 200), and the next tune standby flag F _N 0 is reset. (Step 201)
Proceeding to step 177, a play command signal is sent to the r-th CD player.

Therefore, the designated song indicated by the song selection data written at the x-th position in the performance order list is A, and x + 1 in the performance order list
Assuming that the designated song indicated by the song selection data written second is B, if the designated songs A and B are included in disks mounted on different CD players, the designated song B is In the CD player loaded with the disc including the disc, the disc is selected, the track of the designated music piece B is searched and put into the standby state, and immediately after the performance of the designated music piece A, the standby state is released and the designated music piece is released. The performance of B starts.

When the designated music selection data is written into the above-mentioned performance order list, if the storage capacity is small, it may overflow the storage capacity. When the number y is reached, all the music selection data in the performance order list is deleted, and x, y
May be set to 1.

Next, a door opening data exchange control routine will be described. In this data exchange control routine, opening level determination flag F _C as shown in FIG. 13, it is determined whether or not equal to 1 (step 211). F _C = 0 if the door open flag F _D is 1
Is determined (step 212). If F _D = 0, the processing of this routine ends. Door when F _D = 1
Since 89 is in the open state, set to 1 (step 213) and terminates the processing of this routine opening level determination flag F _C. F _C
= 1, then the door open flag F _D is determined whether equal to one (step 214). When F _D = 1, the door 89 is kept open, and the processing of this routine ends. When F _D = 0, since the door 89 is closed, a request command signal is generated to indicate to the CD players 1 to 3 whether there is a replaced magazine (step 215). In the CD player 1 to 3, when or is newly inserted or disengaged take one of the magazine when the opening of the door 89, a new to no CD player 1 is read TOC data 3 of the internal controller a flag F ₂ to 1 set. Therefore, the controller 11 sets the variable n to 1 (step 216), the flag F ₂ of the second nCD player selects the first nCD player determines whether or equal to 1 (step 217). If F ₂ = 1, the data reading end flag F (n) is reset to 0 (step 21).
8) Add 1 to the variable n (step 219). That is, when F ₂ = 1, the magazine of the n-th CD player has been converted, so that the data reading end flag F (n) is reset to read the TOC data of each disc in the n-th CD player. If F ₂ = 0, there is no exchange of the magazine, so the process proceeds to step 219. Step 2
After the execution of step 19, it is determined whether or not the variable n is greater than 3 (step 220). If n ≦ 3, the process proceeds to step 217,
If n> 3, the data reading end flag F (1), F
It is determined whether (2) and F (3) are all equal to 1 (step 221). F (1) = F (2) = F (3) = 1
If so, this routine ends. However, if any one of the data read end flags F (1), F (2) and F (3) is 0, the process forcibly shifts to step 121 of the disk data read routine. Therefore, the disc number and TO of the disc set in the magazine of the nth CD player in which the magazine has been removed or newly inserted
The C data is written to the RAM 20.

In the above-described embodiment, the data is read and written into the RAM 20 for the discs set in all the magazines of the n-th CD player whose magazine has been exchanged, but the disc set in the newly inserted magazine is read. Only the data may be read.

However, the disc storing operation is performed in a completely opposite manner to the above-described disc loading operation, and will not be described in detail. Hereinafter, the above-described series of operations is repeated according to the designated number of music pieces.

Although not shown, the pickup can be fixed by screws on the side surface of the player housing 402, so that an accident during transportation of the player can be prevented.

Effect of the Invention As described above, in the multiple disc storage / selection performance apparatus according to the present invention, the disc player including the disc containing the next designated music piece to be played following the currently designated music piece is played by the disc player performing the performance operation. Discriminating means for discriminating whether or not the disc is different from the player based on the music selection data. About the performance operation start standby state,
Thereafter, in response to the end of the performance operation of the disk player during the performance operation, the performance operation start standby state is released and the performance operation is started. Therefore, if the disc player equipped with the disc containing the designated song to be played next to the designated song being played is different from the disc player being played, immediately after the performance of the designated song being played ends, the next song is played. Since the performance of the designated music piece can be started, more designated music pieces can be played in a shorter time as compared with the conventional apparatus. The discriminating means can discriminate, from the music selection data, whether or not the disc player provided with the disc containing the designated music piece is different from the disc player in the playing operation, and is discriminated by the discriminating means as a different disc player. In such a case, the preparation for playing the disc player provided with the disc containing the next designated music piece is automatically performed, so that the user does not need to specify the disc player, and the operability is greatly improved.
