ABSTRACT:
A disc clamping apparatus for a compact disc player. The apparatus has a clamp for clamping a disc loaded on a turntable, an elastic wire for upwardly lifting the clamp and for horizontally maintaining the clamp above the turntable, a pair of extension bars connected to a spring to downwardly bias the elastic wire, and a serpentine bar which makes contact with an upper surface of the clamp to allow the clamp to stably rotate. The apparatus does not make contact with the disc while the disc is being inserted/ejected into/from the disc player, so damage to the disc or to the clamp can be prevented. Since the clamp is horizontally maintained above the turntable by the elastic wire, the clamp does not fluctuate while a user is driving the vehicle, so the clamp is prevented from colliding with a cover plate, thereby reducing the noise.
