    • A reproducing apparatus reproduces a disc-shaped recording medium which is accommodated within a case comprising 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, where the lid member having cutouts and ride-over parts. The reproducing apparatus comprises an inserting opening through which the case is inserted, a turntable for rotating the disc-shaped recording medium, a clamping mechanism for clamping at least one of the disc-shaped recording medium and the lid member provided at an innermost part on the opposite side from the inserting opening with respect to the turntable, a lowering and raising mechanism for lowering the disc-shaped recording medium to a position where the disc-shaped recording medium is placed on the turntable from a clamping position where the disc-shaped recording medium is clamped by the clamping mechanism upon starting of the reproduction and raising the disc-shaped recording medium to the clamping position from the turntable upon finishing or discontinuing of the reproduction, a reproducing transducer for reproducing the disc-shaped recording medium placed on the turntable, moving mechanism for moving the reproducing transducer from a waiting position to a reproducing position with respect to the disc-shaped recording medium, a driving source for operating the moving mechanism, a mechanism for rotating the turntable after the disc-shaped recording medium is lowered and placed onto the turntable, and controlling mechanism for controlling the driving source to operate the moving mechanism at a speed selected from among a high speed, semi-high speed, and fast speed (where the high speed is the fastest speed, the semi-high speed is the second fastest speed, and the fast speed is the third fastest speed, and the fast speed is faster than the moving speed of the moving mechanism upon a quick-motion reproduction) according to the operation mode of the reproducing apparatus.
