IGNITION CONTROLLER

PROBLEM TO BE SOLVED: To provide an ignition controller capable of preventing a transistor for a misfire from being turned on even if a leak current is generated, certainly transmitting an ignition timing signal to a trigger, and permitting an ignition plug to be surely ignited at ignition timing. SOLUTION: The ignition controller comprises a magnet generator 2, a controller body 3, a pickup coil 4, and an ignition coil 5. The magnet generator is equipped with a charging coil 6. The controller body 3 is equipped with a misfire control circuit 11 comprising a capacitor 8, a first resistor member 12 and the transistor 13 for the misfire. One end of the first resistor member 12 is connected with a front side of the capacitor 8 in a charging path 14. Among both ends of the charging coil 6, one end is connected with the charging path 14 while the other end is connected with an internal power supply path 17 in the controller. A second resistor member 28 whose one end is grounded is connected with the internal power supply path 17. The second resistor member 28 has resistance lower than that of the first resistor member 12. COPYRIGHT: (C)2009,JPO&INPIT
