Abstract

PURPOSE:To enable a most suitable ignition timing without being influenced by unevenness of an input signal, by controlling a charging and discharging circuit according to an input signal of an output switch circuit. CONSTITUTION:When an output of a signal generator 1 is more than a set voltage of a comparison circuit 21, a transistor 25 turns on and a condenser 20 discharges. While a switch 58 is closed or for the duration from opening of the switch 58 to discharge of a condenser 60, transistors 15 and 18 turn on and a condenser 20 charges. The higher a rotative speed is, the more rapidly the charging is performed. When a charging voltage of the condenser 20 exceeds the set voltage, an output of a comparison circuit 26 is reversed and supplied to an or circuit 31, and an electric current is flown to an ignition coil 4 after turning on a transistor 5 through an output switch circuit 6. This condition continues until a pulse at a (b) point falls. Since a charging level of the condenser 20 is proportional to the rotative speed, an off time of a transitor 5 can be controlled.
