Abstract
PURPOSE: To execute the leading operation of a tone arm rapidly and accurately by detecting the operation time of a switch for commanding horizontal operation and by performing the leading operation at a low speed up to a prescribed time and at a high speed after the prescribed time.
CONSTITUTION: For example, horizontal drive control circuit 20 supplying a driving current to horizontal driving motor 40' for horizontal leading operation of tone arm 100' is constituted as shown in the figure. When timer 11A is put into operation through the operation of lead-in switch 13' and continues to operate continuously for longer than a prescribed time, a control signal which switching change-over circuit 11' is outputted after the prescribed time to change low-speed driving circuit 20A over to high-speed driving circuit 20B. Thus, when the tone arm is led by a small distance, the tone arm is accurately stopped and the leading operation time for long-distance can be shortened.
