Therefore, it can be seen that the disk accommodating space (31) with the category is present in the block (320).

As described above, the apparatus according to this example is characterized in that the disks in the magazine (3) are rearranged, that is, it has a sorting function. Specifically, as shown in FIG. 13 (a), As shown in FIG. 13 (b), the discs D dispersedly accommodated in the plurality of disc accommodating spaces (31) are moved counterclockwise from the disc accommodating spaces (31) facing the loading / unloading section (4). Can be arranged in order. In the description of this example, it is assumed that the disks D are packed from the disk accommodation space (31) having the identification number 1, but the value of the initial identification number can be changed. In addition, the sorting operation is performed using two variables corresponding to the identification numbers of the disk accommodation space (31). In the following description, these two variables are respectively P and N, P is initially set to 1, and N is set to a value larger by 1 than P. After confirming that there is no disc in the disc accommodating space (31) of the identification number P, the disc presence / absence information of the disc accommodating space (31) is searched for from N to the maximum number of identification numbers, that is, 150. When the disc storage space (31) containing the disc is found, the disc is taken out from the disc storage space (31) and moved to the disc storage space (31) with the identification number P. This operation is repeated by increasing the value of P by one. The procedure of the rearrangement operation will be described with reference to the flowchart of FIG.

First, the sort key on the front panel (20)
Press (not shown). The ALU (280) starts the sort operation. The ALU (280) sets the variable P to 1 (S1), and searches the RAM (220) and the non-volatile memory (290) for the presence / absence of a disk in the disk accommodating space (31) whose identification number is 1 (S).
2). If there is a disk in the disk accommodating space (31) corresponding to the variable P, the process proceeds to step S6. If there is no disk, the other variable N is set to a value larger by 1 than P.
(S3). From RAM (220) and non-volatile memory (290), N
The presence / absence of a disk in the disk accommodation space (31) corresponding to is searched (S4). If there is no disc in the disc accommodating space (31), add 1 to N (S8), and N is 15
After confirming that the number is less than 1 (S9), the process returns to step S4 and the search operation is repeated. In step S9, N is 15
1 or the maximum number is exceeded, all disk storage space
Since the search for the presence or absence of the disk in (31) has been completed, the sorting operation is completed. In step S4, the disk storage space (3
If the disc is in 1), the disc stored in the disc storage space (31) with the identification number N is moved to the disc storage space (31) with the identification number P (S5). The specific operation in step S5 is shown in the flowchart of FIG.

First, the magazine (3) is rotated and the identification number N
The disk storage space (31) of the disk is opposed to the recording / reproducing section (7).
(S10). After that, the disc kicking mechanism kicks the disc out of the disc accommodating space (31) toward the recording / reproducing section (7) and energizes the motor (M3) to drive the second and third roller units (60). (61) is rotated and the disc is pulled toward the recording / reproducing section (7) (S11). When the disk has passed the sensor means (SE9) (SE10), the chuck slide (8) slides, the pickup mounting body (71) and the clamper (73) are brought together, and the disk is chucked (S12). In this state, the peripheral edge of the disc does not contact the inner wall of the magazine (3), and the magazine (3) can rotate freely.

Next, the magazine (3) is rotated so that the disc accommodating space (31) with the identification number P faces the recording / reproducing section (7) (S13). After that, the chuck slide (8) slides to separate the pickup mounting body (71) and the clamper (73) from each other, and the third roller unit (61) causes the recording and reproducing unit to move.
The peripheral edge of the disk in (7) is clamped and pulled toward the magazine (3) (S14). The disc is stored in the disc storage space (31) having the identification number P. In this way, the disc originally in the disc accommodating space (31) having the identification number N is moved to the disc accommodating space (31) having the identification number P.

Returning to the flowchart of FIG. 14, the description will be continued. After the disc transfer is completed, 1 is added to the value of the identification number P (S6), and after confirming that P is less than 150 (S7), the process returns to step S2 to repeat the above operation. If P is 150 in step S7, there is no more disk storage space (31) to be sorted, so the transfer operation ends. In this way, the discs scattered in the magazine (3) can be sequentially arranged in the counterclockwise direction from the disc housing space (31) facing the loading / unloading part (4). By arranging the discs packed together, the discs can be taken in and out quickly, and workability when exchanging the discs is improved. Further, since the disks are rearranged in the apparatus body (100) and are not exposed to the outside of the apparatus body (100), there is no fear that the disks will fall out of the apparatus body (100).

In the apparatus according to this example, the disks can be rearranged for each registered category. Specifically, the disks are rearranged in alphabetical order of the initials of the categories, and in the following description, ROCK, CLASSIC,
Magazines belonging to three categories of JAZZ
(3) It is assumed that it is stored inside . For convenience of explanation, R
OCK is represented by R, CLASSIC is represented by C, and JAZZ is represented by J. Therefore, in the sorting completed state, the disks are rearranged in the order of C, J and R. FIGS. 18 (a) to 18 (g) are views showing the sorting operation for each category, where one column is the magazine (3).
Shows one disk storage space (31) inside, 1 from left to right
It has an identification number. The storage state of the disks before the start of sorting is shown in FIG. Sort operation
This will be described with reference to the flowcharts of FIGS. 18, 16 and 17.

First, a category sort key (not shown) is pressed. The ALU (280) starts the sorting operation for each category. ALU (280) is RAM (220) and non-volatile memory (29
All disk storage spaces (31) are searched from 0), and which category is attached to each disk storage space (31) is detected (S20). Next, all the category names are read, and the category from which to sort is determined from the initials (S21). In FIG. 18A, since the initial C of CLASSIC is the youngest in alphabetical order among the three category names, the categories of CLASSIC are sorted first.

The ALU (280) starts the search from the disk accommodating space (31) whose identification number is 1, and
The disc presence information of 1) and the identification number of the disc accommodating space (31) belonging to the category to be sorted are searched (S21, S2).
2) The search operation is repeated up to the maximum number of identification numbers, that is, 150 (S24, S25). The disk storage space (31) that does not contain a disk even if it matches the category to be sorted is excluded from the sorting target. In the example of FIG. 18 (a), the disc accommodation spaces (3
Discs in 1) belong to the category CLASSIC and are the first to be sorted. The ALU (280) temporarily stores the retrieved identification number in the RAM (220), and sets the smallest identification number among the identification numbers belonging to the category as Q (S26). In the case of FIG. 18A, Q is 2. Also, as shown in Fig. 18 (a),
ID number Q, that is, greater than 2 in the state before
An empty disk is stored in the disk storage space (31) with a unique identification number
There is a space (31).

Next, the ALU (280) sets the identification number to N,
The presence or absence of a disk is searched in order from the disk accommodation space (31) where N is 1 (S27, S28). That is, the search is performed from the identification number smaller than Q. If the disk storage space (31) is empty, the process proceeds to step S31. If a disk is stored in the disk storage space (31), it is determined that the disk in the disk storage space (31) is the same as the category to be sorted. To judge
(S29). If the category to be sorted and the disc in the disc accommodating space (31) with the identification number N are the same category, there is no need to rearrange. Categories to be sorted and identification number N
If the discs in the disc storage space (31) belong to different categories, the discs in the disc storage space (31) have an identification number larger than Q and an empty disc storage space (3).
Move to 1) (S30). The procedure for moving the disc is the same as the flowchart in FIG. That is, by rotating the magazine (3), the disc accommodating space (31) with the identification number N is recorded / reproduced.
Stop magazine (3), facing (7). Recording / playback section
Send out the disc toward (7) and temporarily record / playback section
After storing the disc in (7), the magazine (3) is rotated again, and the disc in the recording / reproducing section (7) is moved into the vacant disc storage space (31) of the magazine (3). Figure 18 (a)
In this case, the identification number smaller than the identification number Q = 2 is 1, and the disc containing space (31) of the 1 contains a disc different from the category C. Therefore, as shown in FIG. , Q, the disc is moved to the disc accommodating space (31) whose identification number is larger than Q.

Next, the disk accommodation space (31) with the identification number Q
The disc contained therein is moved to the disc accommodating space (31) having the identification number N (S31). This operation is also the same as that shown in the flowchart of FIG. In the case of FIG. 18 (b), the disc of category C, which was included in the identification number 2, is moved to the identification number 1 (see FIG. 18 (c)). Identification number N is 150
After confirming that it is less than (S32), 1 is added to N (S33). Then, among the identification numbers of the disc housing space (31) belonging to the retrieved category, the next smallest identification number is Q.
(S34), the process returns to step S28, and the rearrangement is performed. In the case of FIG. 18C, the disk to be sorted next is the disk in the disk storage space (31) with the identification number 8. Since the disc accommodating space (31) with the identification number 2 is vacant, the disc is moved to the disc accommodating space (31) with the identification number 2 as shown in FIG. 18 (d) by the determination operation in steps S28 and S31. . Finally Figure 18
As shown in (g), discs can be packed and stored according to category. By performing such rearrangement, the discs can be exchanged quickly when the discs are played for each category, which is convenient.

In the case of sorting by category, if a disc is contained in all the disc accommodating spaces (31), the disc in any one disc accommodating space (31) is recorded / reproduced ( Even if it is moved to 7), other disk storage space (3
1) Since all the discs are contained, the disc storage space (3
Can not be stored except for 1). Therefore, as a premise that sorting can be performed for each category, at least one disc storage space (31) that does not contain a disc
Will be required.

The configuration of each part of the present invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made within the technical scope described in the claims.
