PURPOSE:To permit to realize a desired ignition timing characteristic having a proper angle characteristic and a delay angle characteristic by a simple circuit by a method wherein two series of alternating signals are generated by one set of sensor to make a plurality of reference angle signals and these signals are processed by each different layers. CONSTITUTION:The sensor 2 is provided so as to oppose to two sets of long protruding inductors 1b, 1c provided on the outer periphery of rotor for a magnetic generator 1 and two series of signal voltages are generated from the sensor 2. The signal voltages are inputted into each-different-layer circuit 40 through a waveform shaping circuit 30 and the two series of signals are stratified here into the reference angle signals (f), (g). The reference angle signal (f) is inputted into a delay angle characteristic generating circuit 50 of a mono-stable circuit to generate a pulse signal (h) having a constant pulse width T2 from the rise-up of the signal (f). A thyristor 8 is controlled by taking respective signals (g), (h) and the logics of an invertor output (e) and the charged charge of an igniting capacitor 7 is discharged upon the conduction thereof to obtain an ignition output.
