ABSTRACT:
An automatic loading disc player includes a turntable for rotating a disc to be played back, a disc transfer mechanism for carrying and transferring the disc into a predetermined playback position on the turntable or a position in the vicinity thereof, and a positioning mechanism for positioning the disc in a predetermined position on the disc transfer mechanism. The positioning mechanism is engageable with at least three points on an outer peripheral edge of the disc for positioning the disc and drivable in coaction with disc transferring operation of the disc transfer mechanism. The positioning mechanism is releasable from engagement with the disc while the disc is being played back. The positioning mechanism includes three positioning levers angularly movable by an endless chain for engagement with the outer peripheral edge of the disc. With this arrangement, the disc can accurately and reliably be positioned on the disc transfer mechanism regardless of the diameter of the disc.
