Claims (1)
- 気泡を封入した円形型気泡管を有する気泡部、発光素子を有する発光部、前記発光素子からの光を電気信号に変換する受光素子を有する受光部、前記受光素子の前記円形型気泡管の傾きに対応する受光量を検出する受光量検出部とを備え、前記発光素子と前記受光素子とを直線上に配置し、前記発光素子と前記受光素子との間に前記気泡を配置した鉛直判定センサにおいて、前記発光素子、前記受光素子、及び前記気泡は、それぞれ1個であり、前記発光素子を所定回数点滅させ、点灯状態と消灯状態における受光量の差を求める点滅成分検出手段を備え、前記点滅成分検出手段により求めた受光量の差(A)を、前記鉛直判定センサを用いて、前記傾きの所定範囲で予め求めた前記受光量の差を基に、任意に設定された受光量の差(B)と比較して、AがB以下のときに鉛直と判定することを特徴とする鉛直判定センサ。
