Claims (1)

【実用新案登録請求の範囲】[Scope of utility model registration request] 一　エンジン回転速度信号検出用電磁ピックアップ出力
の点火基準信号と基準電圧とをコンパレータで比較して
実点火信号を演算出力し、エンジン始動時にはスタータ
マスク回路でコンパレータ出力変化を一時的に禁止する
点火時期制御装置に於て、点火基準信号の″０″レベル
より前記基準電圧を高く設定するためにコンパレータ出
力に応答して電源電圧を分圧して前記基準電圧に加算す
る分圧装置７，８を含む誤点火防止装置。(1) A comparator compares the ignition reference signal of the electromagnetic pickup output for engine speed signal detection with the reference voltage, calculates and outputs the actual ignition signal, and when the engine starts, the starter mask circuit temporarily prohibits changes in the comparator output at the ignition timing. The control device includes voltage dividing devices 7 and 8 that divide the power supply voltage and add it to the reference voltage in response to a comparator output in order to set the reference voltage higher than the "0" level of the ignition reference signal. Accidental ignition prevention device.
