Abstract
PURPOSE: To execute the leading operation of a tone arm rapidly and accurately by converting the output of the shift of the position of the tone arm for a desired address into an analog output, and by supplying a driving motor with the current that corresponds to the conversion output.
CONSTITUTION: Horizontal drive control circuit 20 supplying a driving current to horizontal driving motor 40 for the horizontal leading operation of a tone arm is constituted, for example, as shown in the figure. Then, the address output of the shift of the current position of the tone arm for a desired address is converted by A/D converter 21 and the driving current, e.g. shown in the figure, that corresponds to the analog output is supplied to driving motor 40 via driving circuit 23. When the said address output is greater than a prescribed value (e.g., minimum value ϕ or maximum value F), the operation gain of driving circuit 23 is controlled like the chained line in the figure to change leading speeds of the tone arm.
