ABSTRACT:
Rotation of the actuating shaft (4) of the turntable (6) of a compact disk drive unit likewise permits displacement of the turntable between a lowered inoperative position in which it permits movement of the loading drawer (30) supporting the disk (31), and a raised reading position, and securement of the disk on the turntable, without shock or vibration. For this purpose, the turntable co-operates by means of a screwing action with a hollow part (5) integral with the shaft (4). While the turntable raises the disk and removes it from the drawer, a washer (24) mounted on the shaft (4) pushes back towards the exterior an arm (15) mounted to pivot on the turntable, and which firmly clamps the disk on the platform (9) of the turntable. A clutch member (24) integral with the shaft defines the end of travel of the turntable and permits progressive actuation of rotation of the latter.
