Claim:
A disc chucking apparatus of a disc player comprising: a chuck bracket having a clamper for clamping a disc to a turntable; and a lifting/lowering unit for lifting or lowering the chuck bracket to move the disc to a clamping position where the disc is seated on the turntable in the rotatable state or to a clamping standby position where the disc is separated from the turntable, wherein the lifting/lowering unit comprises: a first protrusion part formed at one of first and second ends of the chuck bracket; and a first slider having a first guide slot part formed to be opposite to the first protrusion part so that the first guide slot part receives and guides the first protrusion part to lift or lower the chuck bracket, wherein the first slider is mounted to be capable of reciprocating in the disc loading direction and selectively connected to a power transmission unit, which transmits power from a driving motor, depending on its moving position, thereby being reciprocated.
