Abstract
A multiple compact disk (CD) carousel mechanism for a CD player has a novel loading drawer mechanism employing the combination of a pin arm and a uniquely configured drawer guide slot (within which a pin attached to the end of the pin arm travels) attached to the underside of the drawer for carrying out the following operations: drawer opening; drawer locking in the opened position; drawer closing; and drawer locking in the closed position. The improved design obviates the need for prior art rack and pinion gears for drawer movement, and also obviates the need for separate prior art drawer lock-in and drawer lock-out mechanisms (requiring additional springs, levers and gears).
