の信号処理回路。 The power source of the electric motor that drives the load is controlled on and off by opening and closing the contacts of the power supply circuit, and the closing operation of the push button switch temporarily excites the electric power to close the contact and supply electric power to the electric motor. In a signal processing circuit for an automatic door, etc., comprising a relay that maintains an excited state by the output voltage of a generator rotating in conjunction with the electric motor, the load state of the electric motor is determined by using the output voltage of the generator. An automatic door characterized by comprising: switching means for dividing into a normal region and an overload region; and a transistor of a rotation speed detection circuit that stops power supply to the motor when the output voltage of the switching means falls below a predetermined threshold. signal processing circuits such as
