タの駆動回路。A signal for controlling the rotational phase of a DC motor by an operational amplifier in which a series circuit of a first resistor and a capacitor and a second resistor are connected in parallel between an output terminal and an inverting input terminal, and a rotational speed of the DC motor. In a DC motor drive circuit that rotationally drives the DC motor by differentially amplifying a control signal to keep the voltage constant, a third resistor is connected between the connection point between the first resistor and the capacitor and the ground. and a switching element, the switching element being closed when the DC motor is temporarily stopped.
