ABSTRACT:
A drive mechanism for moving a clamper arm into a standby position of the clamper is simplified and the possible occurrence of the vibration of the clamper in the standby state and the falling of the disc out of the tray in the transferring stage are prevented with a relatively simple construction. Provided is a disc clamping device having a turntable and a clamper which faces the turntable, operating to rotatively support a disc on the turntable with the disc pressed by the clamper, the device being provided with a clamper arm which rotatably supports the clamper and is able to pivot approximately in the direction of its axis of rotation, moving the clamper between a disc pressing position and a standby position, and a clamper arm moving means having a clamper urging plate which pivots the clamper arm as engaged with this and urges the clamper arm toward the turntable side at least in the disc pressing position, whereby the disc is urged against the turntable by the urging force of this clamper urging plate.
