リメートレンズと、対象物から反射して来た前記
発光源からの光を受ける受光レンズと、この受光
レンズを通つて来た光を一次元的に検出する受光
素子とを備え、その受光素子上の結像位置を走査
することで対象物までの距離を測定する装置にお
いて、１つの前記発光源に対しその光軸の回りに
配置した複数組の受光レンズおよび受光素子と、
各受光素子を走査して得た信号のうち最大値を与
える受光素子を選択する比較回路とを備え、この
選択された受光素子からの信号を基に距離を算出
するようにした、測距装置。 A light emitting source, a collimating lens placed on the optical axis of the light emitting source, a light receiving lens that receives the light from the light emitting source reflected from the object, and a primary light receiving lens that receives the light that has passed through the light receiving lens. In a device that is equipped with a light-receiving element that originally detects light and measures the distance to an object by scanning the image forming position on the light-receiving element, multiple sets of light receiving lenses and light receiving elements;
A distance measuring device comprising a comparison circuit that selects a light receiving element that gives the maximum value among the signals obtained by scanning each light receiving element, and calculates a distance based on the signal from the selected light receiving element. .
