PURPOSE:To drive a motor by discharge of a capacitor even at the OFF of an electric power supply on the basis of a simple circuit constitution by operating the motor and a means to be driven automatically by an output from a holding means at the OFF of the power supply. CONSTITUTION:When the power supply 20 is turned off, a diode D11 is also turned off to prevent the charge of a capacitor C11 from discharging to the power supply side and the discharged current is made to flow from the capacitor C11 to the motor 21 through a resistor R14, a transistor (TR) Q3, the motor 21, a diode D12, and a TRQ6 to rotate the motor 21. Consequently, the motor 21 can be rotated by the discharge of the capacitor at the OFF of the power supply without a specific switching circuit like an ordinary case. |
