- 複数の投光器を備え、これら投光器が1つずつ投光するものを変更し、最初の投光器の投光開始から最終の投光器の投光終了するまでを1周期として、この1周期を繰り返し、前記投光器ごとにドア近傍のそれぞれ異なる複数の投光エリアを形成し、異なる前記複数の投光器による投光エリアによって合成投光領域を複数形成するように、前記複数の投光器の投光を投光用光学素子が分散させる投光部と、
前記投光器よりも少数の複数の受光器を有し、前記複数の合成投光領域それぞれと重なる複数の受光エリアからの光を対応する前記受光器に受光用光学素子が集光して、前記各周期ごとに前記各投光器の投光に対応する受光信号を前記各投光器が発生する受光部と、
前記投光器の1周期経過ごとに前記複数の受光器の受光信号のうち選択した1つを出力するように前記複数の受光器の受光信号を受光切換部が切り換え、前記受光切換部から出力された前記選択された受光器の前記各投光器の投光に対応した受光信号が安定した後に、A/D変換部がデジタル受光信号に変換して出力する変換部と、
前記デジタル受光信号を予め定めた閾値と比較して人または物体の有無を判断する制御部とを、
備えた自動ドア用センサ。 - 請求項1記載の自動ドア用センサにおいて、前記各受光器の間には、遮蔽版が設けられている自動ドア用センサ。
- 請求項1記載の自動ドア用センサにおいて、前記複数の投光器は、二次元状に設けられている自動ドア用センサ。
