ABSTRACT:
An automatic diameter selection device for the pick-up arm of a record player. A sensing pin disposed in the turntable is depressed by records greater than a given diameter and cooperates with abutment members to move a plate between a plurality of locked positions. The plate moves only if, after a record has been placed on the turntable, the sensing pin occupies a position which differs from its previous position.
