ABSTRACT:
A signal rotor 6 rotates in synchronism with a crank shaft of the internal combustion engine. A pickup sensor 7 is disposed in a confronting relation to the signal rotor 6 to generate an angle signal S1 proportional to rotation of the internal combustion engine. An ignition signal producing means (31, 32) calculates an ignition timing on the basis of the angle signal S1 and generates an ignition signal (S41, S42) for igniting the internal combustion engine. A time mask means monitors a parameter representative of a battery voltage Vs, and prohibits the angle signal S1 from entering into the ignition signal producing means for a predetermined time in response to a detection of a predetermined amount fluctuation of the parameter.
