サにおいて、センサ本体の前記の穴の形状を球の
直径より大きい孔壁の内周の複数箇所から複数の
突条を中心方向に突出し、その各突条の突出端を
結んで描かれる円をパチンコ球の直径にほぼ合致
させ、突条の各入口部分に傾斜案内を形成したこ
とを特徴とするパチンコ球通過検出センサ。 In a sensor that detects a pachinko ball passing through a hole, the shape of the hole in the sensor body is such that a plurality of protrusions protrude toward the center from a plurality of locations on the inner periphery of the hole wall, each of which is larger than the diameter of the ball. A pachinko ball passage detection sensor characterized in that a circle drawn by connecting the protruding ends of the stripes almost matches the diameter of a pachinko ball, and an inclined guide is formed at each entrance portion of the protrusion strips.
