PURPOSE: To ensure the smooth and assured loading and draw out actions of a disk to a disk player main body by energizing a drive member to a movable member for their unified horizontal shift, shifting the drive member only along the movable member when the movable member stops at a prescribed position and revolving a holding member set up/down slidably to the movable member in response to the shift of the drive member for up/down movements of the holding member.

CONSTITUTION: When a switch button is pushed after putting a disk 1 on a holding member 2, a drive motor 9 is driven to drive linearly a drive member 18 toward an arrow A along an oblong groove 8a. A contact bar 3d of a movable member 7 operates the 2nd detection switch 32, and the member 7 stops its movement. However the motor 9 continues its revolutions, and the member 18 moves further toward A along the member 7. Then the member 2 provided to a slide shaft 2b which hooks to a cam groove 5a formed to a rotary cam 5 is revolved toward an arrow C along the slide surface to be shifted downward. During this down-shift of the member 2, the disk 1 is put on a turntable 25. Then a clamp pate 23 is turned toward an arrow D and therefore a clamper 26 moves toward D together with the plate 23. Thus the disk 1 is pressed to the table 25.
