Abstract
The present invention relates to a clamping apparatus for a disc player which is able to accurately release a clamper from a turntable while improving miniaturization and thinning. The clamping apparatus for the disc player where the turntable and the clamper clamp a disc by magnetic force comprises a clamper releasing means having a pair of linking mechanisms arranged in symmetrical positions across the axial line of the clamper, and each linking mechanism has a front linking member and a rear linking member with the ability to freely rotate with the frame by centering two rotational axes placed on a single flat surface that is orthogonal to the axial line, and a clamper releasing member which is axially supported at each rotating end of the front linking member and the rear linking member; the mutually opposing ends of both clamper releasing members are moved with a circular trajectory by synchronously rotating the front linking member and the rear linking member, and the ends of both clamper releasing members are engaged to the outer periphery of the clamper, releasing the clamper from the turntable.
