Abstract

PURPOSE:To prevent reverse rotation effectively, by keeping a transistor in conduction before it reaches the peak rise time of voltage from the time when a self-shortcircuiting regulator is set into actuation, and thereby increasing the conduction width of the transistor. CONSTITUTION:Voltage of a charge coil 1 is impressed to the base of a transistor 11 via a diode 19 and a resistance 20. Here, since the transistor 11 can be energized also by the plus voltage of charge coil 1, the conduction width of transistor 11 is increased toward the opposite side of an ignition signal at the time of normal rotation, so that operation is carried out normally in this state. At the time of reverse rotation, however, the conduction time of transistor 11 is increased since it is energized by the charged voltage and an advancing ignition signal can be also shortcircuited. Therefore, it is enabled to cause misfiring without fail at the time of reverse rotation within an operable range of a pulser.
