On an outer peripheral portion of a rotor (1), three protrusions are provided per each cylinder. A pickup coil 2 is disposed facing to the outer peripheral portion with a predetermined distance. A rotation signal (S0) is converted to a rotation signal pulse (S1) having three pulses (A, B and C) per each cylinder corresponding to the three protrusions. According to the first signal (A) of the rotation signal pulse (S1) the cranking ignition period (A1) is determined. According to the second signal (B) of the rotation signal pulse (S1), the starting timing for flowing current to the ignition coil (8) is decided. According to the third signal (C) of the rotation signal pulse (S1), the ignition timing at cranking operation is defined by detecting time intervals (3t, t, 2t) between the three signals (A, B, C).
