<p>PURPOSE:To perform the positioning of a player means with high accuracy at a position corresponding to each tray of a magazine by providing a ratchet mechanism operating on a rotary member selectively. CONSTITUTION:When a disk to be played is designated, a tray extruding member 50 provided at a supporting member 18 is positioned at an engaging position with the tray supporting the disk to be played. A solenoid plunger 40 is kept at an on-state while the supporting member 18 is being moved, and the lug 39a of the ratchet mechanism is disengaged from a ratchet 38, and no operating tone of the ratchet mechanism is generated while the supporting member 18 is being moved. When the positioning of the supporting member 18 is completed, a motor 35 is stopped, and simultaneously, the solenoid plunger 40 is turned off. Thereby, the ratchet 38 of the ratchet mechanism is engaged with the lug 39a with the pressing force of a coil spring, and the playing means loaded on the supporting member 18 is positioned at the position corresponding to the tray supporting the disk to be played with high accuracy.</p> |
