Title: Method for discriminating reflecting surface of plane mirror
Inventor: HONOKI HIDEYUKI
IPC: G02B5/08
Filed: 1988-09-19
Abstract: PURPOSE:To easily discriminate the surface of a plane mirror from the rear so as to prevent such erroneous assemblage that the surface side of the mirror comes to the rear side by making part of the surface having no relation with the reflecting performance of the mirror nonreflective. CONSTITUTION:One surface of the base material 4 of this plane mirror 2 is provided on a reflecting surface 1 and a nonreflecting area 2 is provided outside the reflecting performance effective area 3 of the surface 1. When a light source is placed at the back of the mirror 5 and the light source is observed from the front side, almost all of the rays of light from the light source are blocked by the mirror 5, but the rays of light transmitted through the nonreflecting section 2 are observed. Since the reflecting surface 1 is on the front side when the position of the nonreflecting section 2 observed after the reflecting surface is turned by 180 deg. under such state is symmetrical to the original position about the mirror 5 and on the rear side when the section 2 comes to the position adjacent to the original position after the surface 1 is turned by 180 deg., the surface side of the mirror can be discriminated easily and such erroneous assemblage that the surface side comes to the rear side can be prevented.
