Claims

[Scope of utility model registration request]

A contact point that opens and closes according to the engine-driven cam intermittents the primary current of the ignition coil flowing from the battery, and distributes the generated secondary current to each cylinder using a distributor to prevent reverse rotation in a two-stroke engine that ignites. A rotating body that rotates together with a cam that opens and closes the contact point;
a non-contact detection device that detects a specific rotational position of the rotating body corresponding to the point operation time point when the engine is reversed; a waveform shaping circuit that detects when the contact point is open and outputs a shaped pulse; It is composed of an AND gate that outputs a shaped pulse of the waveform shaping circuit when a detection signal of the non-contact detection device is generated, and a relay that interrupts the primary current of the ignition coil flowing from the battery by the output of the AND gate. A reverse rotation prevention device for a 2-cycle engine featuring:
