Abstract
A disc player device includes a tray transfer mechanism for transferring a tray, supporting a disc thereon, from a magazine, a clamper for holding the disc, and a clamper drive mechanism for transferring the clamper to a turntable. The disc is held by the turntable with the clamper transfer mechanism held out of contact with the clamper, and in this condition a playback of the disc is carried out. After the playback of the disc is finished, the disc is again clamped, and is returned to a predetermined position by the clamper transfer mechanism. The tray transfer mechanism, the clamper, the clamper drive mechanism are driven by a common motor.
