ABSTRACT:
The invention relates to a disc playing apparatus, in which a disc inserted through a disc inserting slot is held on a turntable for playing back data with an optical pick-up, and released from the turntable and forced back to the outside of the disc inserting slot. The disc playing apparatus can be simple in construction, small in size, and inexpensive in the cost of manufacture. A disc holder for transferring the disc takes hold of the outer edge of the disc. The operations of the disc holder and a clamping mechanism are controlled by a timing control mechanism, which is driven by a single motor. The timing control mechanism has a partial gear. The timings of operation of various parts are controlled by selectively using a with-teeth portion and a without-teeth portion of a partial gear. The timing control mechanism is reversibly operable in dependence on the direction of motor rotation. Various parts of the apparatus are reversibly operable when loading and unloading the disc.
