Patent ID: 7774805

Claim:
A disk clamping device, comprising: a swing arm which is swung into and swung out of a space created by splitting disk housing sections capable of housing a plurality of disks; a drive unit which is mounted on the swing arm and plays the disk, the drive unit having a turning table on which the disk is mounted and a disk clamping mechanism which holds the disk with the turning table; a drive mechanism for driving the swing arm; and a transmitting member which transmits drive power of the drive mechanism to the clamping mechanism, wherein the disk clamping mechanism has a clamp arm provided so as to be able to move up and down in substantially parallel with a disk surface, and a pressure-bonding section which is provided rotatably on the clamp arm and pressure-bonds the disk onto the turning table when the clamp arm moves downward, the drive mechanism has an auxiliary arm which rotates and thereby biases the swing arm in a swing-in direction and a swing-out direction, and the transmitting member is provided rotatably by being biased by an end section of the auxiliary arm.
