摘要： An output circuit for outputting a control signal through a transistor to a controlled apparatus including an output detecting section for detecting the control signal and an external power supply for supplying a power to the output detecting section, a voltage due to the external power supply being applied to between a collector and emitter. The output circuit comprises a capacitor coupled in parallel to an output detecting circuit comprising the output detecting section and the transistor coupled in series to each other and resistor means coupled in series to a parallel circuit comprising the output detecting circuit and the capacitor so as to give a series resistance with respect to the parallel circuit. The output circuit further comprises a switch disposed to be parallel to the resistor for bypassing the resistor to substantially reduce the series resistance up to zero when a voltage between terminals of the capacitor is above a predetermined value. This arrangement can prevent the transistor from instantaneously taking the ON state, thereafter ensuring the normal operation by bypassing the resistor means through the switch.
