To form a means preventing a logic circuit from outputting wrong data at uncontrolled, unstable state of power turn-on in a control circuit. The control circuit has two logic circuits therein and takes negative OR or negative AND of output thereof. A first input terminal is connected to an input of an inverter circuit and a second logic circuit; the output of the inverter circuit is connected to the input of the first logic circuit; a second input terminal is connected to the first logic circuit and the second logic circuit; outputs of the first logic circuit and the second logic circuit are connected to inputs of a gate circuit; the output of the gate circuit is connected to a output terminal; and the first logic circuit and the second logic circuit output the opposite level to each other, positive and negative.
