ABSTRACT:
A compact disk player/changer for compact disks fits within the standard half-height disk drive form factor for computer peripherals. A disk, either a 5-1/4-inch or 31/2 inch in size, is inserted through an aperture and supported, at opposite contact points on its edge, between laterally movable left and right-side disk guides. The disk's left side is frictionally engaged by a belt revolved on the left-side disk guide. The disk's right side rolls along a fixed wall on the right-side disk guide. The belt slides along a rigid wall of the left-side disk guide that prevents bowing from pressure exerted by the disk's edge. A motor that drives the revolving belt is fixedly mounted on a chassis. An extensible transmission transmits rotational force from the motor to a timing pulley to propel the belt on the laterally movable left-side disk guide. The extensible transmission consists of gear train on a pair of hinged members to provide a thin profile. The use of the extensible transmission reduces the movable weight, reducing the power and bearing load of the movement mechanism. In addition, the clearance required for a moving drive motor is avoided.
