ABSTRACT:
A disc loading/unloading apparatus according to the present invention is driven by motor power in interlock with the insertion condition of a disc and pushing out the disc from the operating position outside the apparatus. The apparatus includes positioning members for contacting the outer perimeter of the disc at spaced locations on the perimeter upon insertion of the disc into the opening, a spring for urging the positioning members against the outer perimeter of the disc for holding the disc in a loaded position and a disc ejection mechanism for ejecting the disc from the loaded position. The disc ejection mechanism includes an unloading lever for pushing the disc toward the opening and a rotatable cam for counteracting the biasing force of the spring and releasing the disc from the urging of the spring until the disc moves toward the opening beyond a predetermined position.
