摘要： PROBLEM TO BE SOLVED: To solve the problem that it is difficult to make high resolution due to the limit of refining a code pattern or the like on a code plate.
SOLUTION: The optical encoder consists of a light source part, a light receiving part, and the movable code plate 4 located between the optical paths of both the parts, in which the well known pattern for detecting an absolute position to detect the information of the absolute position of the code plate 4 is formed on an outside track T2 on the code plate 4, and a phase type diffraction grating is formed on an inside track T1. Then the relative position information of the code plate 4 is detected based on the interference beam of two diffraction beams diffracted with the phase type diffraction grating and therefore detection with high resolution can be done from the combination of both the information.

SOLUTION: A position-detecting method in an optical encoder includes a light-emitting section; a signal track where a modulating pattern for reflection or passage is formed by the presence of a V-style section having a shape reflecting incident light; a light-shielding track where a V-style pattern equal to a detecting section is formed; a resin optical scale providing a permeation region for permeating the incident light; a light-receiving section detecting transmitted light from the signal track, light-shielding track, and permeation region; and a signal-processing unit performing the position detection of a scale, based on each detection signal on the light receiving section. Therein, the quantity of light from the permeation region and quantity of light from the light-shielding track are detected; the quantity of light from the permeation region and the quantity of light from the light-shielding track are compared; and then the changes in the temperature for the ratio of the light entering the V-style section and passing through it is determined. Then, quantity of light from the signal track is detected, and the position of the optical scale is detected by compensating the quantity of the light from the signal track, based on the ratio of the light entering to the light passing through the V-style section passes.
