路に対向して配置された発光素子及び受光素子と
、該通路に関して他側に配設された反射面とを有
していて、該通路中に物体がない場合には、発光
素子からの光が該通路を横切つて上記反射面に入
射し、この反射面により反射された後に再び上記
通路を横切つて受光素子に入射するようになつて
いるが、該通路を物体が通過したとき、該物体に
より発光素子から受光素子への光路が遮断される
ことにより、物体の通過が光学的に検出されるよ
うにしたことを特徴とする、物体検出装置。 A light-emitting element and a light-receiving element are disposed on one side facing the passage through which the object passes, and a reflecting surface is disposed on the other side with respect to the passage. When there is no object in the path, the light from the light emitting element crosses the path and enters the reflecting surface, and after being reflected by the reflecting surface, it crosses the path again and enters the light receiving element. However, when an object passes through the passage, the optical path from the light emitting element to the light receiving element is blocked by the object, so that the passage of the object is optically detected. Object detection device.
