| titleOfInvention | Optical encoder and manufacturing method thereof |
| abstract | The present invention provides an optical encoder capable of maintaining stable detection accuracy even in an environment where there is a possibility of contact with steam, cutting oil, etc. at a high temperature of about 100 ° C. to 130 ° C. And in manufacture of the code board used for an optical encoder, it aims at ensuring the sufficient lifetime of the metal mold | die of a code board, and the high reliability of the molded product (code board) obtained. The present invention relates to an optical encoder comprising a light projecting portion, a light receiving portion, and a code plate made of a resin material, wherein the code plate includes a V-shaped groove or a V-shaped projection. And the resin material has an index of refraction of 1.6 or more with respect to light having a wavelength used for detection at 130 ° C., and a glass transition point of 190 ° C. or less. It is.
