(Automatic Performance Mode) In this apparatus, a magazine
(3) It is possible to set a mode in which discs belonging to the same category accommodated in (3) are continuously reproduced. This mode is called an automatic performance mode, and the applicant has previously disclosed in
176176 proposes a device having an automatic performance mode. To set the automatic performance mode, the operation shown in the flowchart of FIG. 10 is performed. First, the automatic operation key group
The C / A switching key (710) of (700) is operated (S10). In the category / artist display field (370) of the display (330), a character string of "SELECT CATEGORY" is displayed.

Next, the up key (740) or the down key (730) in FIG. 2 is operated (S11). A category name is read from the nonvolatile memory (290) in response to a key input, and the category name is displayed in a category / artist display field (370). Further, as described above, the segment (310) of the display section (300) corresponding to the block (320) including the disk accommodating space (31) to which the category name is assigned is turned on. When the desired category name is displayed in the category / artist display field (370) (S12), the user presses the play button (170) (S13). The apparatus main body (100) is set to the automatic performance mode (S14).

When a signal from the reproduction button (170) is input to the system control means (600) through the bus line (230), the automatic performance means (620) is set in the disk accommodation space (31) belonging to the category. Port (26)
Emitting to the changer mechanism (400) via 0). The user rotates the magazine (3) and plays from the disk in the disk accommodation space (31) with the smallest identification number among the disk accommodation spaces (31) with the displayed category name (S1).
Five). Thereafter, the disks are similarly played one after another (S18), and when the performance of all the disks belonging to the selected category is completed, the automatic performance operation ends (S17).

(Automatic Insertion and Ejection Mode) The apparatus according to the present embodiment is capable of successively ejecting discs in the disc accommodating space (31) to which the same category or artist name is assigned.
It is characterized in that it can be inserted again into the disk accommodation space (31). That is, if there is a disk in the disk accommodation space (31) to which the same category or the artist name is assigned, the automatic ejection mode for taking out the disk is set. Conversely, in all of the disc storage spaces (31) with the same category or artist name,
If no disc is inserted, the automatic insertion mode is set so that discs belonging to the same category or artist name can be inserted continuously. Since the category name or the artist name is stored for each disc accommodation space (31), when the category name is displayed in the category / artist display column (370) of the display (330), the category name or the artist name is displayed. Even if no disk is inserted in the corresponding disk accommodation space (31), the segment (31) of the display unit (300) corresponding to the block to which the disk accommodation space (31) belongs.
0) lights up. The automatic insertion mode and the automatic ejection mode are automatically switched according to the presence or absence of a disc in the disc accommodating space (31) assigned the same category or artist name. Hereinafter, this operation will be described with reference to the flowcharts of FIGS.

First, as in the automatic performance mode, the C / A switch key (710) and the up key of the automatic operation key group (700) are set.
Operate the (740) or down key (730) to display the desired category name in the category / artist display field (370).
(S20). As described above, the display unit (300) of the display (330)
Each segment (310) in the corresponding block (320)
If there is a disk accommodation space (31) to which the category name is assigned, the light is turned on. After this, the load / eject button (130) is
Press for more than a second (S21). Timer means (29 in the processor (200)
In 5), it is determined whether or not the button is pressed for 5 seconds or more. If it is 5 seconds or less, the automatic insertion or ejection mode is not set. If the key is pressed for more than 5 seconds, the fact is notified to the system control means (600). Automatic insertion / ejection means (63
0) retrieves from the nonvolatile memory (290) and the RAM (220) all the disk accommodation spaces (31) with the same category name as the selected category name, and searches the disk accommodation space (31). A search is made as to whether a disc is inserted in () (S22).

(Automatic insertion mode) If the disk does not enter all the disk accommodation spaces (31) belonging to the same category, the automatic insertion and ejection means (630) inserts the disk into the apparatus main body (100) as described above. To automatic insertion mode. The migration procedure is shown below. First, the identification number N of the disk accommodation space (31) to be searched is set to 1 (S23), and the contents in the RAM (220) and the nonvolatile memory (290) are sequentially arranged from the first disk accommodation space (31). The search operation is performed from. If the disk accommodation space (31) of the identification number N does not match the previously selected category name, the process proceeds to step S27, and if it does, the presence or absence of a disk in the disk accommodation space (31) is searched. (S24, S25). The disk storage space (31)
If there is no disc in the changer mechanism
(400) is set to a state in which a disk can be inserted (S26). That is, the magazine (3) is rotated, and the disc accommodating space (31) of the identification number N in which no disc is inserted is inserted into the loading / unloading section.
The rotation of the magazine (3) is stopped while facing the (4). After that, the first roller unit (6) is rotated in the disk loading direction. When the passage of the disk is detected by the sensor means (SE7) (SE8), it is detected that the disk has been pulled into the magazine (3).

After the insertion of the disc is completed, it is determined whether or not the identification number N is the maximum number, that is, 150 (S27). If the identification number N is the maximum number, the process exits the automatic insertion mode. If N is not the maximum number, it is determined whether the stop button (160) has been pressed (S28), and the stop button (16
If (0) is pressed, exit from the automatic insertion mode. If there is no input from the stop button (160), 1 is added to the identification number N, and the process returns to step S24 (S29). The reason why the search operation is performed by shifting the identification numbers one by one is to prevent omission of the search in step S22. That is, a certain disk accommodation space (31) belongs to the selected category,
This is also to prevent the possibility that a disc is not inserted in spite of the fact that the disc is stored, and that the disc is not inserted afterwards. The search operation is an operation in the processor (200), and the search time is very short.

(Automatic Ejection Mode) If a disk is in any of the disk accommodation spaces (31) belonging to the same category, as described above, the automatic insertion and ejection means (630) moves the disk out of the apparatus body (100). Shift to automatic discharge mode to discharge
(See FIG. 12). First, similarly to the automatic insertion mode, the identification number N of the disk accommodation space (31) to be searched is set to 1 (S30). The disk accommodation space (31) of the identification number N is
If it does not match the previously selected category name, the process proceeds to step S34, and if it matches, the disk accommodation space (3
The presence or absence of the disk in 1) is searched (S31, S32). If there is a disk in the disk storage space (31), the changer mechanism (400) is set to a state where the disk can be ejected (S).
33). That is, the magazine (3) is rotated so that the disk storage space (31) containing the disk faces the loading / unloading section (4), and the rotation of the magazine (3) is stopped. After that, the first roller unit (6) is rotated in the disk ejection direction. When the disk has passed the sensor means (SE3) to (SE6), it is detected that the disk has been completely ejected. Thereafter, as shown in steps S34 to S36, the above operation is continuously performed until the identification number N reaches the maximum number, which is the same as the automatic insertion mode, and detailed description is omitted.

Since such a disk reproducing apparatus can store a large number of disks, it can be used not only as a reproducing apparatus but also as a storage box for disks, and is mainly used indoors. However, in recent years, with the spread of car stereos, portable players, and the like, discs have been increasingly used outdoors. In order to take the discs outdoors, a plurality of discs belonging to a specific category must be placed in a magazine (3). May be taken out of In the device according to the present embodiment, in the automatic ejection mode, the disc accommodating space belonging to the same category is used.
Since the discs in (31) can be successively ejected, it is convenient to take out the discs from the magazine (3) when taking the discs outdoors. In addition, when discs belonging to the same category taken outside are stored in the original position again, the automatic insertion mode is set, so that the usability is good.

In the apparatus according to this embodiment, the category name and the artist name are stored independently in the RAM (220) and the nonvolatile memory (290). In the automatic performance device according to Japanese Patent Application Laid-Open No. 7-176176 previously proposed by the applicant,
The artist name is called a sub-category and is ancillary to the category name, and performs an automatic performance mainly based on the category name. However, in the apparatus according to the present embodiment, automatic performance and automatic ejection can be performed based on any of the category name, the artist name, or the title name at the discretion of the user.

The description of the above embodiments is for the purpose of illustrating the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made within the technical scope described in the claims.
