ABSTRACT:
An extremely simple record changer mechanism is provided wherein only two members interconnect the tone arm subassembly with the main cycling gear in the spindle area of the changer. One of these members is employed to lift and lower the tone arm and the other member is used for the dual purpose of moving the tone arm horizontally during the record changing cycle and also acts as a velocity trip actuating member during the playing cycle. Both members are designed to avoid damage to the mechanism if the tone arm is moved or restrained during the record changing cycle.
