PROBLEM TO BE SOLVED: To provide a motor control circuit which can contrive cost down, life elongation, and downsizing. SOLUTION: A motor control circuit 20 is equipped with a transistor 21 which performs the ON/OFF of the power voltage to be applied to a DC motor 7, a resistor 26 which detects the current flowing to the DC motor 7, a thyristor 23 which zeros the base potential of the transistor 21 by turning it on, and an integrated circuit which comprises a resistor 24 and a capacitor 25 for integrating the voltage across the resistor 26 and applying voltage to the gate of the thyristor 23. |
