Patent ID: 8001558

Claim:
A clamping apparatus for a disc player, comprising: a clamper ( 110 ) having an axial line placed between the frame ( 5 ) and the turntable ( 13 ); magnetic means to clamp a disc between the turntable and the damper; damper releasing means ( 112 ); and driving means ( 113 ) to release the damper from the turntable with the clamper releasing means by driving the clamper releasing means, wherein said clamper releasing means has a pair of linking mechanisms ( 111 ) arranged in symmetrical positions across the axial line of the damper; each linking mechanism comprises a pair of rotational axes ( 131 ) placed on a plane orthogonal to said axial line, a front linking member ( 124 ) and a rear linking member ( 125 ) having respective rotating ends while being attached with the ability to rotate synchronously relative to the frame by centering the rotational axes for each end respectively, and a clamper releasing member ( 123 ) having respective mutually opposing ends while being axially supported respectively at each rotating end of the front linking member and the rear linking member; wherein each of the rotational axes of the front linking member and the rear linking member in both linking mechanisms are mutually parallel; and the opposing ends of the clamper releasing member scoop the rim of the clamper while forming a circular trajectory at the time of synchronizing rotation of the front linking member and the rear linking member of both linking mechanisms causing the clamper to release from the turntable.
