After storing and holding the disk storage case 1 inside, the conveyor 44 is further raised, moves to a specific address position of the disk storage section 31 where the disk storage case 1 is stored, and stops. When the conveyor 44 is locked, the slider drive motor 64 is driven in reverse to move the slider 60
The first pair of hook members 7 moves toward the one disk storage section 31 side, and the hook member 7 of one pair moves.
The disk storage case 1 held at 0.70 is pulled into the disk storage section 31. When the first operation piece 102 provided on the slider 60 presses the first detection switch 101 and detects that the slider 60 has reached the first position, the slider drive motor 64 is stopped and A pair of solenoid plungers 79, 79 for rotating the one pair of hook members 70, 70 are turned on, causing the hook members 70, 70 to rotate, and the engagement pawl 72 at the tip of the hook member 70, 70, 72
from the engagement recesses 7, 7 of the disk storage case 1. Then, the holding of the disk storage case 1 by the hook members 70, 70 is released, and the operation of pulling the disk storage case 1 into the disk storage portion 31 is completed.

In the above operation description, the disk storage case 1 stored in one of the pair of opposing disk storage sections 31, 31, which is the one on the left side in FIG. 10, is selected and pulled out. Although we have described the case where the stored optical disc 3 is played, the disc storage case 1 stored and placed in the other disc storage section 31 located on the right side in FIG. 10 is selected and pulled out to store this disc. Optical disk 3 stored and held in case 1
When playing the disc storage case 1, the drawer transport operation of the disc storage case 1 is carried out in substantially the same manner as in the case described above, and the disc table 4 of the optical disc 3 is moved.
The optical disc 3 that has been played is then stored and held in the disc storage case 1, and the disc storage case 1 is pulled into the disc storage part 31.

By the way, in the case of the present invention, as described above, even one of the multiple disk storage cases 1 is not correctly stored and placed in the disk storage section 31, and for example, the disks protrude from the disk storage section 31 and the through holes 25 If the infrared light from the infrared lamp 26 is blocked and the photodetector 27 does not detect it, the photodetector 27 outputs an operation cutoff signal, and the disk drawer mechanism 32 and disk All operations of the transport mechanism are stopped.
