Claims (1)
配置された発光素子及び受光素子を有しており、
該通路を物体が通過したとき、該物体にて発光素
子から受光素子への光路が遮断されることにより
該物体の通過が検出されるようにした光学式セン
サにおいて、上記光路の通路から受光素子側に、
該光路の光軸上に中心を有するほぼ円形の複数の
スリツトが備えられていることを特徴とする光学
式センサ。 (2) 前記発光素子から受光素子への光路の光軸
が、物体が通過すべき通路の中心からずれている
ことを特徴とする、実用新案登録請求の範囲第１
項に記載の光学式センサ。[Claims for Utility Model Registration] (1) A light-emitting element and a light-receiving element are arranged opposite to each other across a path through which an object should pass,
In an optical sensor, when an object passes through the passage, the passage of the object is detected by blocking the optical path from the light emitting element to the light receiving element by the object. on the side,
An optical sensor comprising a plurality of substantially circular slits whose centers are on the optical axis of the optical path. (2) Utility model registration claim 1, characterized in that the optical axis of the optical path from the light emitting element to the light receiving element is offset from the center of the path through which the object should pass.
The optical sensor described in section.
