Abstract

PURPOSE:To prevent the playing state without a record disc, by inhibiting the turning of turntable at the application of power supply, in response to the output of the rest detection means to detect the rest position of the tone arm. CONSTITUTION:The output of the integrating circuit 1 to integrate the power supply voltage and the signal of the rest detection means to detect the rest position of the tone arm are input to the logical product gate 3, and the means 7 detecting the state of end of lifting up of the tone arm and the signal of the rest detection means 4 via the inverter 5 are input to the logical sum gate 6. Further, the outputs are taken as the set and reset input of the flip flop 8 to drive the phonomotor 10. Accordingly, even if the tone arm lifts down with the power supply in error without a record disc, since the rotation of the turntable is blocked, the damage to stylus tip can surely be prevented.
