Abstract
A tone arm moving mechanism is provided wherein the tone arm is normally moved over the lead in groove and lowered to the record during the last half of a normal record changing cycle. Means are then provided which are operative during a last record shut-off cycle for lowering the tone arm into a retaining means on the rest post, said retaining means being effective to restrain the tone arm from inward movement during the remaining portion of the last record shut-off cycle.
