Patent ID: 7716692

Claim:
A disc device capable of recording/reproducing information signals with respect to a disc, comprising: a traverse base that can be moved between a recording/reproducing position and a standby position, on which an optical pickup for recording/reproducing the information signals with respect to the disc and a turntable for holding and rotating the disc at a position where the optical pickup can record/reproduce the information signals with respect to the disc are mounted; a front cover comprising a disc carrying surface that carries the disc and an aperture that is formed in the disc carrying surface and allows the turntable to pass through when the traverse base is moved between the recording/reproducing position and the standby position; and centering members for holding and shifting the disc to a position where a center of the disc is aligned with a center of the turntable, wherein the centering members come into contact with the disc so that they are symmetrical about a first plane that contains the center of the turntable and is perpendicular to a disc holding surface of the turntable and a second plane that contains the center of the turntable and is substantially perpendicular to the first plane, two pairs of the centering members are arranged symmetrically with respect to the first plane, and each pair of the centering members is rotatable symmetrically with respect to the second plane.
