摘要
The purpose of the present invention is to provide a resin encoder scale enabling processing to be made simple and costs to be reduced by manufacturing the encoder scale as a resin molded article having a gradation pattern. A resin encoder scale (1) can be used by an encoder of a reflective-type optical system, and is provided with a gradation pattern (2) for position measurement. The gradation pattern (2) is configured so that the following are disposed alternately and repeatedly: low reflectance sections (3) having low light reflectivity and the surfaces of which are formed when resin molding to be rough; and high reflectance sections (4) having higher light reflectivity than the low reflectance sections (3) and the surfaces of which are formed when resin molding to be specular.
