Claims

[Claims for Utility Model Registration] (1) A device for detecting specular reflection on an object to be detected, which includes a light source illuminating the object to be detected, and receiving light reflected from the object by the illumination of this light source. and a detection window provided between the object to be detected, the light source, and the light receiver, and a portion of the detection window that separates the illumination system and the light reception system for blocking light. 1. A specular reflection detection device comprising a partition member. (2) The specular reflection detection device according to claim 1, wherein the detection window is made of a transparent glass plate. (3) The specular reflection detection device according to claim 1, wherein the object to be detected is a mail piece having a so-called cellophane window.
