ABSTRACT:
A disc clamping mechanism includes a clamp board, a clamp base, a first supporting unit and a second supporting unit. The clamp board rotatably clamps a disc in cooperation with a turntable to be rotated in a housing. The clamp base rotatably supports the clamp board at a position opposite to the turntable, and is movable so as to move away from or come into contact with the turntable. The first supporting unit comes into contact with a first peripheral edge of the clamp board protruding from the clamp base when the clamp board moves away from the disc according to the movement of the clamp base, to exert pushing force in a direction of the turntable side and pushing force in a direction of the clamp base side against the first peripheral edge. The second supporting unit is provided at the clamp base, and securely supports the second peripheral edge of the clamp board situated at a position opposite to the first peripheral edge when the first peripheral edge is pushed by the first supporting unit.
