た２枚のミラーを有し、入射光に対し常に９０度
屈折した反射光を反射するコーナミラーを前記角
部に設置したことを特徴とする光線式監視装置。[Scope of Claim for Utility Model Registration] Light is projected from a projector onto a plurality of monitoring surfaces in a dangerous area, the projecting light is received by a light receiver via a reflecting mirror provided at a corner, and the light is output from the light receiver. In the optical monitoring device, which detects changes in the amount of light based on received light signals and performs processing to avoid danger when the amount of light decreases, the reflecting mirrors include two mirrors placed opposite each other at an angle of 45 degrees. A light beam monitoring device characterized in that a corner mirror is installed at the corner to reflect reflected light that is always refracted by 90 degrees.
