A coiled spring is provided between pivotable frame and door member so as to constantly urge the door member against a rear surface of a front panel, and the projections provided on the operation portion of the door member are engageable with recesses in the back surface of a front panel. An elongated opening is provided in the front panel and receives a disc cartridge thereinto, the elongated opening being opened and closed by and with the door member. The mechanism has fewer parts than the conventional mechanism, and can be manufactured efficiently at a lower cost.
