Abstract
A record player having a turntable, a pickup arm and a trip mechanism, the trip mechanism comprising a lever 21 which pivots about a pivot and which is constrained to remain against a first stop member 32 until a first predetermined time in the playing cycle of the record player, mover means comprising arm 30 attached to pick up arm cation spindle 26, for pivoting the trip lever away from the first stop member and against a second stop member 34 whereby an electrical current can pass from the second stop member, and reset means for resetting the trip lever by pivoting it back to its position against the first stop member at a second predetermined time in the playing cycle of the record player. The current can initiate set down of the pickup arm or can initiate return of the pick up arm or start of an automatic change cycle. Also described is an arrangement for setting down of the pick up arm at the start of records of different sizes. <IMAGE>
