Output circuit for outputting control signal to controlled apparatus

An output circuit for outputting a control signal to a controlled apparatus, said output circuit being coupled to an external power supply, said output circuit comprising:

• transistor means for providing said control signal to said controlled apparatus, where a voltage is applied from said external power supply across a pair of output terminals of said transistor;
• adjusting means including a capacitor and a resistor coupled to said external power supply and to said transistor for gradually increasing said voltage between said output terminals of said transistor means and for preventing instantaneous turn-on of said transistor means when said voltage is initially applied across said output terminals of said transistor means;
• and
• stopping means coupled with said adjusting means for stopping the operation of said adjusting means when said voltage across said output terminals of said transistor means increases above a predetermined value which is determined by said capacitor and resistor.

An output circuit for outputting a control signal to a controlled apparatus, said controlled apparatus including an output detecting section for detecting said control signal and an external power supply for supplying power to said output detecting section, said output circuit comprising:

• transistor means for outputting said control signal to said controlled apparatus, where voltage produced by said external power supply is supplied to said transistor;
• a capacitor coupled to said external power supply in parallel with an output detecting circuit comprising said output detecting section and said transistor means coupled in series to each other;
• and
• resistor means coupled to said external power supply, said resistor means and external power supply being connected to a parallel circuit comprising said output detecting circuit and said capacitor, said resistor means having a series resistance with respect to said parallel circuit so that said voltage applied to said transistor means is gradually increased by said capacitor and resistor means after the start of supplying said power from said external power supply so that instantaneous turn-on of said transistor means is prevented when said power is initially supplied.
