Abstract: PURPOSE:To stably connect a load unit to a driving power source without causing a shock, by using the voltage of a capacitor, which is charged and discharged through a constant current circuit, to energize a drive circuit for controlling the operation of a clutch. CONSTITUTION:When a clutch engaging signal is applied to one terminal of a resistor 1 at time t1, a capacitor 6 starts being charged and the voltage of the capacitor is applied to the positive terminal of an operational amplifier 8. The voltage of a clutch 14 is applied to the negative terminal of the operational amplifier 8 through a resistor 7 and a voltage Vcc is impressed on another terminal of the operational amplifier. For that reason, the output of the amplifier 8 is 0V. When the terminal voltage of the capacitor 6 has gradually risen to V1 lower than Vcc, the operational amplifier 8 produces an output voltage which is K times hihger than V1 and the emitter voltage of transistors 11, 13 rises to V1. The voltage applied to the clutch 14 increases in proportion to the emitter voltage so that the clutch is smoothly put into a connected state without causing a shock.
