(Ignore the operation of the α key 107) and if the α key 107 is not input, the process proceeds to M8 shown in FIG.

If the disc is inserted in step S81, the process proceeds to M7 shown in FIG. The presence / absence of the input of the α key 107 is determined in step S83 because the user may input the α key 107 again to enter the α mode.

According to the above embodiment, the empty storage section of the stocker 5 is detected in the stock mode, and the empty storage section in which the inserted disk should be stored is set. If the empty storage section is not designated by the keys (103 to 106), the inserted disk is stored in the set empty storage section. It is not necessary to perform a designation operation for designating an empty storage section with the keys (103 to 106).

If the disc is not inserted after a predetermined time elapses after the automatic setting of the empty storage section is performed, the stock mode is automatically released without performing the release operation, for example, the opening / closing door 217. Since it is set to the locked state, it is possible to overcome the situation that a foreign object enters through the opening / closing door 217 while the lock is released.

When the opening / closing door 217 is in the unlocked state, the disk insertion sensor 216a for detecting the insertion of the disk, the CPU 233, etc. must be energized.
By putting 17 in the locked state, it is possible to reduce unnecessary power consumption.

Also, during the α mode in which the MD device is switched to the single-player device, the storage section (5
0a to 50d) corresponding to the displayed No. Lamp (10
3a to 106a) are turned off, and the No. corresponding to the α key 107 is displayed. Since only the lamp 107a is lit and displayed, the user can improve the operability as a one-player device.

When the α mode is released, that is, when the α disc is ejected, the No. Lamp to <br/> lever so again lit and displayed (103a-106a), without requiring a switching operation of the display means when switching from one player device to auto-changer device, MD as subsequent auto-changer device It is possible to overcome the situation where the use of the device is hindered.

In the above embodiment, the carrier 3
Although the standby position of the above is the position facing the opening of the storage part 50b, it may be any position as long as the opening / closing door 217 is in the locked state.

Further, in step S62 shown in FIG. 8, the disc is stored in the designated storage portion. At this time, the disc is once mounted in the player portion 4 and the contents of the TOC information unique to the disc are stored. For example, the album name recorded on the disc, the total playing time of the disc, or the like may be read and stored in the memory 225 before being stored in the designated storage unit. When the disc is reproduced next time, the music selection operation for the disc can be quickly performed.

If a time-out is detected in step S41 shown in FIG. 7, the last-stored disc or the first-stored disc is loaded in the player unit 4 to reproduce the disc. However, in this case, it is possible to save the user's labor for the disk reproducing operation.

Further, according to the above-described embodiment, the storage section 50a of the stocker 5 is # 1 and the storage section 5 is the disk storage order.
0b is # 2, storage section 50c is # 3, storage section 50d is # 4.
However, the storage section 50a is # 4, the storage section 50b is # 3,
The storage portion 50c may be # 2 and the storage portion 50d may be # 1, and the storage portion 50b may be # 1 and the storage portion 50a.
May be # 4, and the storage section 50c or the storage section 50d may be # 2 or # 3. Further, various variations can be considered regardless of the storage order.

The MD device can store up to 5 discs, but it is possible to store a larger number of discs by increasing the number of storage portions of the stocker 5. Needless to say.

In the above embodiment, the recording medium is the MD, and the description is applied to the MD device. However, the recording medium is a CD, an optical recording medium such as a video disk, or a magnetic recording medium such as a floppy disk. By
It goes without saying that the same can be applied to an apparatus that handles these recording media.
