複写機の速度制御装置。 The servo motor 1 that drives the driven body 2 is set to PLL.
In the case where the speed is controlled by a circuit, the rotational speed of the servo motor 1 is detected by a rotation detector as a sine wave frequency proportional to the rotational speed and a voltage proportional to the rotational speed, and this is full-wave rectified by a full-wave rectifier circuit 9. A speed control device for a copying machine which feeds back the obtained speed signal to the mixing amplifier 6 of the PLL circuit.
