ABSTRACT:
A reproducing apparatus reproduces a loaded disc-shaped recording medium derived from a case. The case comprises a jacket which has a space for accomodating 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 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 or the lid member provided at the innermost part on the opposite side from the inserting opening with respect to the turntable, a detecting mechanism for detecting whether the disc-shaped recording medium is loaded within the reproducing apparatus, and an arresting mechanism provided at the vicinity of the inserting opening, for arresting the insertion of a jacket having the lid member into the reproducing apparatus and allowing the insertion of a jacket not having the lid member into the reproducing apparatus, by displacing according to the detecting operation of the above detecting mechanism. The arresting mechanism allows the insertion of the jacket having or not having the lid member into the reproducing apparatus in a state where the detecting mechanism is not performing a detecting operation.
