Abstract
【解決手段】リレー駆動回路は、カレントミラー回路、電流抑制回路26、およびトランジスタQ3を備える。カレントミラー回路は、トランジスタQ1、第1抵抗素子R1、トランジスタQ2および第2抵抗素子R2によって構成されている。リレーコイル18は、トランジスタQ1のコレクタ端子から接地導体に至る電流供給路に設けられている。カレントミラー回路は、第1抵抗素子R1、トランジスタQ1、およびリレーコイル18が形成する第1電流路に流れる電流を、第2抵抗素子R2、トランジスタQ2、電流抑制回路26およびトランジスタQ3が形成する第2電流路に流れる電流に応じて調整する。電流抑制回路26は、トランジスタQ2のエミッタ端子とコレクタ端子との間が導通した後に、その導通時に比べて自らに流れる電流を抑制する電流抑制素子としてキャパシタC1を備える。
