ABSTRACT:
A disc clamping device of a compatible disc player, by which a mini disc or a compact disc can be selectively loaded on a single turntable clamps either the mini disc or the compact disc. The disc clamming device has a base plate including two side walls each having a reversed "L" shaped cut-out portion, a supporter extending upward, a clamper arm and a rotating body pivoting about a hinged shaft fastened to the supporter, an actuating rod projected through the lower end of the rotating body, a folded forward portion having a clamper mounted thereto; a moving plate having a arcuate portion defined in the lower corner of the rear end thereof, a rack gear, and a stepped cut portion formed in side thereof; a tray holder receiving a compact disc tray and a mini disc tray; and a loading device. Since the disc clamping device is simple in construction, stable operation is ensured and manufacturing cost is reduced. Clamping force of the clamper can be conveniently controlled by adjustment of the angle between the clamper arm and the rotating body.
