PURPOSE:To hold assuredly an optical disk by pressing a conical centering core to the center part of a disk clamper and opening a pawl-shaped matter to hold tightly the optical disk. CONSTITUTION:A disk cassette case 1 storing an optical disk 6 is set to a player with the side of a cover 3 turned down in a reproduction mode. Thus the case 1 is moved down toward an arrow head A by a loading mechanism when the coincidence is obtained between the rotary center of a centering core 15 set at the tip of a motor shaft 14 and that of a disk clamper 10. Then the conical core 15 is pressed into the center part of the clamper 10. Thus a pawl-shaped matter 11 of the clamper 10 is opened outside and the inner wall surface of the center hole of the disk 6 is pressed. As a result, the clamper 10 can hold assuredly the disk 6 to secure the assured connection with the shaft 14. |
