ABSTRACT:
An optical disk player wherein a chassis having an optical pickup, a disk table and the like mounted thereon is supported by a frame using elastic support means at a plurality of positions, a vessel filled with a viscous fluid and sealed is provided at either the frame or the chassis, and a movable member provided at the other of the two is arranged in the sealed viscous fluid. With this arrangement, the slope of the Q curve in the resonant region is moderate enough to improve the antivibration characteristics, thus substantially eliminating sound omissions.
