Claims (4)
- 装備対象物に形成され且つ人の手又は指が挿入される開口の周辺位置に露出させることなく配設された一対の電極板と、所定周波数の電気信号を生成するとともに一方の電極板に出力する発振部と、他方の電極板から出力された電流を電圧に変換して出力する電圧変換部とを具備したことを特徴とする近接センサ。
- 請求項1記載の近接センサにおいて、他方の電極板の外側に近接して配設されたシールド電極と、高インピーダンス入力−低インピーダンス出力である回路部であって、他方の電極板が入力側、シールド電極が出力側に各々接続されたインピーダンス変換部とを具備したことを特徴とする近接センサ。
- 請求項1記載の近接センサにおいて、電圧変換部の出力段に設けられており、基準電圧を調整可能に生成する一方、電圧変換部の出力電圧と当該基準電圧との差分を求め、当該差分電圧を増幅した電圧を出力する出力調整部を具備したことを特徴とする近接センサ。
- 請求項1記載の近接センサにおいて、電圧変換部は、他方の電極板から出力された電流の電荷を蓄えるコンデンサと、コンデンサに蓄えられた電荷を放電する抵抗とを有した構成であり、当該抵抗の抵抗値が調整可能になっていることを特徴とする近接センサ。
