Claims (1)
無及びその通過速度を検出するようにした光検出装置に
おいて、光源から物体通過位置までの光の経路と、物体
通過位置から受光器まｔの光の経路とを透明体にて構成
し、この透明体を保持した保持台を所定箇所に設置する
ことにより、晃が光源から物体通過位置を経て受光器へ
中継されるようにしたことを特徴とする光検出装置。In a light detection device in which a light source and a light receiver are arranged facing each other and detect the presence or absence of an object passing between them and its passing speed, the light path from the light source to the object passing position and the light path from the object passing position to the light receiver are detected. By configuring the light path of the light and the light path with a transparent body, and installing a holding table that holds this transparent body at a predetermined location, the light is relayed from the light source to the light receiver via the object passing position. A photodetection device characterized by:
