Hereinafter, the operational effects of the apparatus of the present invention configured as described above are as follows.

Inserting the magazine 35 into the tray in the state of FIG. 3 (b) allows the disc to be removed from the magazine 35 to be loaded and seated on the turntable 27 for loading of discs. a) The space must be secured in the state. Therefore, after detecting that the magazine 35 is inserted, the magazine 35 and the tray plate 25 are moved forward by rotating the tray feed intermittent gear 17 as the horizontal moving motor 18. In the intermittent gear 17, the synchronous gear 91 assembled to the synchronization shaft is bitten so that the synchronous power is also connected to the gear 29 and the rack on the right side.

In addition, the synchronous gear 19 on the right side causes the gear 37 and the rack 22 to move horizontally inside the main body.

The transfer plate 20 moves to the right by the power transmission plate 21. The cam curve 20c changes the position of the shaft 36a, so that the clamper 26 assembled to the clamper plate 36 turns the turntable 27. Moves from the A position to the B position, push the locking lever 12 to rotate the counterclockwise while overcoming the force of the spring 23, and push the pin 13a to the left to move the rocker 13 to the left. In close contact with the bending part 2a in the wedge direction, the locking guide pins 21a and 21b are positioned at the right end of the guide hole 2c.

In addition, as the protruding piece 20b rotates the idle lever 11 counterclockwise to rotate the lifting lever 10, the lifting gear 7 moves upward, so that the power of the gear 6 is switched. It is dropped and power transmission to the elevating gear 7, the pulley gear 9 and the polygear 14 is possible.

That is, when the motor 18 rotates the horizontal movement, the tray feed becomes possible when the tray is opened, and the tray feed is racked by the synchronous gear 19 and the gear 37 connecting the power of the intermittent gear 17. (22) moves to the right, and the transfer plate (20) also moves to the right, so that the projecting piece (20b) rotates the idle lever (11) counterclockwise so that the power connection is made from the gear (6) to the polygear (9). ) And the projection 21c rotates the locking lever 12 counterclockwise to move the rocker 13 to the left to lock the guide pins 21a and 21b of the guide hole 2c. It locks to the right to lock into place.
