Abstract

A record player having a mechanism for guiding and centering records of different sizes on a driving spindle. Two pairs of levers are mounted on a record carrier at diametrically opposed positions. The levers have generally circular hubs mounted on pivots carried by the record support and extending arms including record engaging studs. Insertion of a record engages the studs to pivot the arms which guide the record to a centered position. Alignment of slots in the hubs of at least one of the pairs of levers sense the proper positioning of the record and trigger the player to rotate the record carrier from the load to the play position.
