A rotary recording medium reproducing apparatus reproduces a rotary recording medium on a turntable after an operation is performed in which the case accommodating the rotary recording medium therein is inserted into the reproducing apparatus and the case is then extracted from the reproducing apparatus with leaving the rotary recording medium with the apparatus. The reproducing apparatus comprises a jacket opening enlarging mechanism for engaging with the jacket to enlarge the opening according to the movement of the enlarging mechanism towards the innermost part of the reproducing apparatus from an inserting opening according to the insertion of the case, and a locking mechanism provided at a position substantially center along right and left directions of the enlarging mechanism, for normally locking the enlarging mechanism in the vicinity of the inserting opening to restrict the movement of the enlarging mechanism towards the innermost part of the reproducing apparatus. The locking mechanism is maintained in its original locking state upon insertion of the case or jacket in a state where a front edge of the case or jacket is slanted with respect to the enlarging mechanism, and assumes a locking released state only when the front edge is parallel with the enlarging mechanism and the locking mechanism is pushed by the front edge.

Rotary recording medium reproducing apparatus having a jacket opening

A rotary recording medium reproducing apparatus reproduces a rotary recording medium accommodated within a case, where the case comprises a jacket provided with a space for accommodating the rotary recording medium and an opening for allowing the rotary 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 rotary recording medium reproducing apparatus comprises an inserting opening through which the case is inserted, a turntable for rotating the rotary recording medium, a lid member locking mechanism and rotary recording medium clamping mechanism respectively provided at an innermost part of the reproducing apparatus opposite to the inserting opening with respect to the turntable, a jacket opening enlarging mechanism provided in the vicinity of the inserting opening, capable of moving over the turntable between a position in the vicinity of the inserting opening and the innermost part of the reproducing apparatus, in response to an operation in which the case is inserted into and pulled out from the reproducing apparatus, an elevator mechanism for raising and lowering a rotary recording medium supporting member for supporting the rotary recording medium, independently from the turntable, an elevator motor for operating the elevator mechanism, when the elevator motor operates so that the support member is at a raised position due to the operation of the elevator mechanism upon insertion of the case into the reproducing apparatus, and an elevator lever member provided respective of the elevator mechanism, for operating the elevator mechanism by operating independently from the elevator motor. The elevator lever member is positioned within a moving passage of a locking guiding part which is a part of the jacket opening enlarging means. Further, the elevator lever member is locked and guided by the locking guiding part and displaced towards a direction so as to operate the elevator means to lower the supporting member so that the supporting member retreats from a case inserting path upon insertion of the case into the reproducing apparatus, and is released of the locking operation by the locking guiding part and displaced towards an opposite direction so as to operate the elevator means to raise the supporting member upon extraction of the case from the reproducing apparatus.

Rotary recording medium reproducing apparatus

A reproducing apparatus reproduces 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 an inserting opening part through which the case is inserted into the reproducing apparatus, a turntable for rotating the disc-shaped recording medium, lid member locking mechanism and disc-shaped recording medium clamping mechanism respectively provided at the innermost part of the reproducing apparatus opposite to the inserting opening with respect to the turntable, jacket opening enlarging mechanism provided in the vicinity of the inserting opening, moving over the turntable between the position in the vicinity of the inserting opening and the innermost part of the reproducing apparatus, accompanied by operation of inserting the case into and pulling the same from the reproducing apparatus, and an elevating mechanism for moving a member for supporting the disc-shaped recording medium upwards and downwards independent of the turntable.

Disc-shaped recording medium reproducing apparatus

A rotary recording medium reproducing apparatus reproduces a rotary recording medium accommodated within a case where the case comprises a jacket provided with a space for accommodating the rotary recording medium and an opening for allowing the rotary 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 rotary recording medium reproducing apparatus comprises an inserting opening through which the case is inserted, a turntable for rotating the rotary recording medium, a lid member locking mechanism and rotary recording medium clamping mechanism provided at an innermost part of the reproducing apparatus at an opposite side from the inserting opening with respect to the turntable, where the rotary recording medium clamping mechanism consists of an upper clamping member and a lower clamping member which is at a downwardly inclined rotated position upon non-clamping state and at a horizontal rotational position upon clamping state, an operating mechanism pushed and displaced by the case inserted into the reproducing apparatus, for operating the lid member locking mechanism and the rotary recording medium clamping mechanism, a locking mechanism for locking the operating mechanism at a final displaced position, and a restricting mechanism constructed from a part of the lower clamping member of the rotary recording medium clamping mechanism and a part of the operating mechanism, for restricting the displacing movement of the operating mechanism towards the final displaced position at an intermediate position when the lower clamping member is at the downwardly inclined rotated position.
