Abstract
Loading and unloading mechanism for slot type disc player apparatus incorporates a device for transferring a disc to the disc drive after it has been inserted through a slot and for transferring the disc from the disc drive and ejecting it through the slot after the playing operation has been completed. A disc carrier plate is mounted on the frame of the apparatus for helical movement between a first position adjacent the slot and a second position adjacent the disc drive. A spring or a motor provides power to rotate the carrier plate, which rotational movement is translated to helical movement by helical ramp members and cooperating bearing members. Control devices are included to provide automatic operation.
