ABSTRACT:
In a phonograph record player having a tone arm carrying a pickup with a stylus to track the groove of a phonograph record on a turntable during a play operation and being mounted for lead-in movement from an elevated rest position outside the turntable perimeter to a selected set-down position of the stylus on the record for commencement of a play operation and for return or lead-out movement back to the rest position on termination of a play operation, a control mechanism is provided with a single mode selecting member or slide which is manually movable to positions for selecting stop, manual and repeat modes of operation, respectively, of the record player. More particularly, the manual mode selecting position of the slide and positions of the latter for selecting repeat modes of operation providing progressively increasing numbers of repeated play operations are arranged in order in the direction away from the stop mode position of the slide, and for each play operation of the record player the mode selecting slide is displaced in a step-wise manner toward its stop mode position. Further, at an extreme position of the mode selecting slide remote from the stop mode position, successive play operations are obtained without corresponding step-wise displacements of the slide so that the play operations are repeated indefinitely.
