PURPOSE:To surely load a disk without causing a timing slippage by constructing a single timing mechanism pressing a disk to a turn table by releasing the holding of a held disk. CONSTITUTION:A disk D is held on a moving plate 1, its pin 14 is engaged with grooves 11, 13 and the disk is carried inwards together with the driving plate 8 driven by a motor 18. When a pin 26 is transferred to an inclined part 12b from the horizontal part 12a of the groove, a linking plate 22 is converted to the center and a clamp member 20 abuts the center hole 29 of a disk opposing to a turn table. The movement of the moving member 1 is regulated with a louvering member 28 abutting to a regulating member 27, the pin 26 reaches the horizontal part 12c of the groove at the timing of the clamp member 20 abutting to a center hole 29, the movement of the linking plate 21 is stopped and the disk becomes rotatable. The disk can surely be clamped without causing any timing slippage on the transfer of the disk and the clamp operation onto the turn table.
