Abstract
[Object] To provide a method for manufacturing a scale having an improved abrasion resistance, the scale, and an encoder having the same. [Solving Means] A scale base material 17 is arranged on the upper surface of a mount 26. A pattern base material 18′ as a material of pattern portions 18 are laminated on the upper surface of the scale base material 17. In this laminated state, the pattern base material 18′ is punched toward the scale base material 17 via a press work. Accordingly, the punched pattern base material 18′ is embedded and held in a thickness of the scale base material 17, and the pattern portions 18 are formed.
Claims10
A method for manufacturing a scale characterized in that a pattern portion is formed by punching a pattern base material toward a scale base material via a press work in a state in which the pattern base material is laminated on the surface of the scale base material, and embedding at least part of the punched pattern base material in a thickness of the scale base material to be held therein.
A scale comprising a scale base material and a pattern portion embedded in a thickness of the scale base material, characterized in that a detection pattern is formed by arranging a plurality of the pattern portions at a regular pitch in a row.
