Claims

[Claims for Utility Model Registration] 1. A code plate 3 that moves together with the moving object is arranged between the light source 1 and the light receiving element 2, and a code formed by a combination of a light transmitting part 12 and a light blocking part 11 is provided on the code plate 3. In an optical movement measuring device that forms a column 9 and detects the amount of movement based on a combination of optical signals received by the light receiving element 2, a cylindrical body 5 made of a translucent material is placed between the code plate 3 and the light receiving element 2. are arranged so that the radial direction of the cylindrical body coincides with the optical axis 8 connecting the light source 1 and the light receiving element 2, and the boundary between the light blocking part 11 and the light transmitting part 12 in the code row 9 is formed by an inclined straight line. An optical movement measurement device characterized by: 2 A plurality of code rows 9 are arranged concentrically on the code plate 3, and a light blocking portion 11 is provided in the code row 9a located at the outermost periphery.
The optical movement measuring device according to claim 1, which is a utility model, and has a sawtooth shape with a constant pitch. 3 Utility model registration claim 1 in which a plurality of code rows 9 are arranged in parallel on the code plate 3, and the light blocking portions 11 in the code row 9a located at the lowest side are formed in a sawtooth shape with a constant pitch.
The optical movement measurement device described in .
