Abstract
PURPOSE: To lift up or return the tone arm according to the operating condition of the drive set immediately before the application of power supply, by adding the integration circuit integrating the power supply voltage and the rest detection means for the tone arm.
CONSTITUTION: The logical product gate circuit 26 producing the instruction signal by taking the output of the integration circuit 24 integrating the power supply voltage and the return state signal as input, and the logical product gate circuit 27 producing the reference signal by taking the output of the integration circuit 24 and the signal from the rest detection means 28 to detect the absence of the tone arm at the rest position as input, are provided. Further, those signals are taken as one input of the logical sum gates 32, 33 to control the drive set motor 1. Accordingly, even if the power supply is applied while the tone arm is located on the turn table, the tone arm can be driven in response to the state immediately before the application, enabling to prevent unpleasant tone and damage of stylus tip.
