Abstract
A record disc player apparatus of the type having a front loading drawer incorporates a centering mechanism for centering record discs of different diameters. At least three movable studs are disposed generally equidistantly about an axis of the loading drawer and are carried by support members mounted to the underside of the bottom of the drawer. Slots in the bottom of the drawer guide the studs inwardly generally toward the axis from a position spaced outwardly of the periphery of a larger of the different record discs which the loading means is adapted to carry concentric with the axis. The movable supports carrying the studs are interconnected for coordinating inward movement of the studs to engage the periphery and center a smaller record disc supported on the loading drawer only after a predetermined displacement of one of the movable supports. The predetermined inward displacement of the one support and the stud carried thereby is used to sense the presence of a larger record disc, which causes the one stud to return outwardly to avoid interference with the larger record disc. After a smaller record disc is carried to a operating position on the turnable of the player apparatus, the studs are moved away from the smaller record disc to allow its free rotation.
