Abstract
A disc player apparatus having mechanism for guiding and centering disc records of different size on a disc record drive having a vertical spindle. A horizontal plate for receiving a disc record inserted and movable along a horizontal path to a position centered on the spindle has spaced levers pivotally movable laterally outwardly from a first position straddling the center line of the path and resiliently urged toward each other; the levers have a first position spaced sufficiently to engage an inserted disc record of either a small size or a large size and be moved outwardly thereby against the resilient element to guide a record of either size to centered position. A pair of generally L-shaped stop members are mounted on the plate straddling the center line in the path of an inserted small size record to locate such a record in its centered position. Two elements actuated by outward movement of both said levers by a large size record are employed for shifting the stop members out of the path to permit a large size record to move to its centered position. A safety and disc record detection circuit is provided.
