Abstract

PURPOSE:To reduce chucking torc by controlling the position of a driving pin for performing the rotational driving of a disk in order to nullify the energy in the radial direction of the disk. CONSTITUTION:The driving pin 16 is guided by the engaging surface 19a of a driving pin engaging hole 19, is moved, and completes the chucking. The stopper of a rotary lever 14 in its rotation direction is fulfilled by the pin 16 and a hole part 12a provided on a rotary plate 12. Accordingly, at the time of chucking the disk, no chucking spring force in circumferential direction occurs, and the driving pin 16 maintains an angle <90 deg. with respect to both engaging surfaces of the engaging hole 19 to apply a contact pressure. Therefore, the pin 16, being guided by the engaging surfaces of the hole 19, can be moved to a chucking position with a small chucking torc.
