Abstract
A reproducing apparatus reproducing a disc-shaped recording medium which is accommodated within a case. The case comprises a jacket which has a space for accommodating the disc-shaped recording medium and an opening for allowing the disc-shaped recording medium to go in and out of the jacket, and a lid member inserted through the opening of the jacket for closing the opening of the jacket, the reproducing apparatus comprises a holding mechanism for holding and leaving the disc-shaped recording medium inside the reproducing apparatus when the case is inserted into and then pulled out from within the reproducing apparatus in a direction opposite to the direction of the insertion and a clamping mechanism for clamping the disc-shaped recording medium on a turntable. The clamping mechanism comprises a support member which is unitarily rotatable with the turntable and capable of independently moving up and down with respect to the turntable, for supporting the disc-shaped recording medium at the vicinity of a center opening thereof, a moving mechanism for moving the support member upwards and downwards, clamping fingers provided in the support member, for pressing against the disc-shaped recording medium near the center opening thereof to clamp the disc-shaped recording medium on the turntable when operated, and an operating mechanism for rendering the clamping fingers into an operational state upon completion of the downward movement of the support member. The clamping fingers are positioned at an inoperative position when the support member is being raised.
