It is detected and displayed on the disk display section 61.

Next, before taking out the disk 2 from the magazine 3 and transporting it, the disk switch lever 63 is rotated by the cam portion 14k of the drive rack 14 to a position where the switch piece 62C does not come into contact with the disk 2, and then the disk 2 is removed from the magazine 3. When the disk 2 is taken out and conveyed and the disk 2 is taken out and conveyed to a position where the switch piece 62C does not touch the disk 2 by the return of rotation of the disk switch lever 63, the disk switch lever e3 can be returned to rotation again by the pull spring 66. I can do it. Also, when the magazine 3 is inserted into the magazine base 5 at a rapid rate, the tension spring 73 is stretched by the load of the differential rack 27 and the insertion speed of the magazine 3 is relaxed. If the long hole 14h' of the drive rack 14 is pushed too far, the drive rack 1
4 can be prevented from moving too far in the A direction and causing the tray to be pulled out incorrectly.

The positional relationship between the drive rack 14 and the differential rack 27 in FIG. 11 is the position shown in FIG.
When the differential rack 27° is driven by the head of the drive rack 14 in the direction of the arrow A, the pushing part 27b of the differential rack 27 pushes the convex part 83bf of the lock release lever 83 and rotates in the direction of the arrow. Then press tray 1 and lock lever 78.

At the initial stage when the drive rack 14 is driven in the A direction, the tray hook block 13 is pressed against the stopper part 120 of the loading base 12 and the compression spring 7o is compressed, as explained in FIG. Even if the drive rack 14 moves in the A direction, the tray hook 10 does not move in the A direction even if it moves in the A direction. Therefore, the tray 1 cannot be pulled out in the A direction. At this timing, the tray 1 and the lock lever 78 are unlocked, and when the drive rack is further driven in the A direction, the slide piece 68 is moved to the stone bar 6.
9 to drive the tray hook block 13 in the A direction and pull out the tray 1. Further, when the drive rack 14 is driven in the A direction, the pushing portion 27b of the differential rank shown in FIG.
After passing in the A direction, the lock release lever 83 is rotated back in the force direction by the tension spring 85, and the tray 1 in the magazine 3 is locked again by the lock lever 78.

When the performance is finished and the tray 1 is driven toward the opening and stored in the magazine 3, push W27bH of the differential rack pushes the convex inclined portion 83b of the lock release lever 83 to rotate it toward the opening. Return to the original position shown in Figure 3.

When the lock release lever 83 is pushed by the pushing part 27b of the differential rack and rotates in the direction of the arrow, the convex part 831L at one end pushes the lock lever 78 and the thin part 83d bends.
The letter-shaped spring holder is part 83e.

The wire spring 86 inserted through the wire spring 83f can prevent permanent deformation of the thin portion 83d and prevent deterioration of the spring effect.

Also, the hook portion 6b of the magazine lock lever 6 is located in the recessed portion 3d.
You can prevent the magazine 3 from overrunning toward the mouth by pressing .
