Abstract

PURPOSE:To evade the evil influence of a spark noise by stopping the generation of a clock pulse from the input of an ignition signal to the operation of a comparator. CONSTITUTION:When an ignition signal is supplied, an FF17 is set and its output is supplied to an FF14. When the output of a freqency dividing circuit 13 changes into a ''0'', the FF14 is reset to close the gate of an AND circuit 12, and consequently a clock from a clock generator 11 is not outputted to the circuit 13 any more. The reset output of the FF17 turns off a transistor (TR) 19 and a capacitor 21 is charged with a current from a current source 20. Then, when the charging voltage of the capacitor 21 exceeds a comparison voltage, a comparator 22 operates and the signal ''0'' of an NOR circuit 25 resets the FFs 17 and 14 to open the gate of the AND circuit 12, so that a clock pulse is outputted from the frequency dividing circuit 13.
