Abstract
Abstract Record playing apparatus includes a housing (12) having an opening at the end, a record carrier assembly (1) having a turntable (6) for supporting a record disc (5) and a tone arm (4) for reproducing signals from the record disc (5), guide rollers (11) which support the record carrier assembly (1) for horizontal movement through the opening between the first position within the housing (12) and a second position withdrawn from the housing (12), a dust cover (24), a pair of elongated arms (20) pivotally mounted at one end thereof to opposing sides of the record carrier assembly (1) and having the dust cover (24) connected to the free ends thereof, springs (23) for biasing the arms (20) to move the dust cover (24) to a first cover position in blocking relation to the opening when the record carrier assembly (1) is moved to its first position, and cam bars (32) for biasing the arms (20) against the force of the springs (23) when the record carrier assembly (1) is moved to its second position so as to move the dust cover (24) out of the blocking relation and into a slot (19) formed in a mounting frame (15) secured to the front end of the record carrier assembly (1).
