Since the tray 18 passes over the tip 201 of the stopper 20, the restriction on the horizontal movement of the tray 15 is released, and the t+-ray 15 begins to move horizontally toward the slot 66.

The second cam member 13 carries the i-ray 15 together with the first cam member 13.
When the cam member 14 slides on the second rail 12 and reaches a predetermined position, the front end and four moving surfaces 14C of the second cam member 14 slide on the lock member 75, as shown in FIG. 1st
The locking member 75 is rotated from the state shown by the solid line to the state shown by the 1τ dotted line against the a-1 force of the spring 7/I. The [1-clicked] state of the C door 68 is released.

Rays 1 to 15 continue their horizontal movement (), and the disk 7 is returned to the thrower 1 at 66, and a portion of U (s 1) protrudes from the fourth part 66a of the slit 6G. Hold this protruding part slightly with your fingers. When it is lifted, the disk 7 is released from the support by the disk supporting members 55 and 56 and is pushed out from the stages 1 to 66 by the lever 57 and recovered.

According to the present invention, as detailed below. t-1 ~ [1-Ding disk brake (7 is a type in which an image such as a hidden 71 j" disc or digital A-disc is inserted from the slot). The space on the top surface of the play V can be used effectively.

Furthermore, the A-drawing disc player according to the present invention is equipped with a gamma transport mechanism that automatically transports the disc inserted from the thrower to the performance broker, thereby reducing the effort required to load the disc. It's because it's omitted.

Further, in the A-th loading disc play 17 according to the present invention, when the disc is transported and reaches a predetermined position, a door provided at the stage A is closed by a door lock mechanism. This locks the slot in the slot and prevents fingers or other objects from being inserted into the slot during performance, making it highly safe and particularly effective when a laser beam is used to pick up recorded information.
