Abstract

PURPOSE: To obtain high accuracy and high resolution by molding the code plate integrally with its rotary shaft while the coding plate is equipped with an adjusting mechanism which makes the axes of rotation of the code plate coincident with a rotary driving mechanism automatically and fitting the coding plate to the adjusting mechanism through the shaft and making adjustments for the alignment at the time of laser plotting.
CONSTITUTION: The main body of the coding plate 1 and its rotary shaft 1a are formed integrally and the inner periphery of the cylindrical wall of the main body is a material surface to be exposed. Further, the coding plate is equipped with the rotary axis adjusting mechanism 17 for making the axes of rotation of both the rotary driving mechanism 16, composed of stages 3 and 4 and goniometers 5 and 6, and the code plate 1 coincident with each other automatically. Further a couple of distance sensors 7a and 7b are provided in the cylinder of the coding plate 1 and the distance to the inner peripheral surface of the cylindrical wall corresponding to the angle ϕ of the rotation of a rotary base 2 is detected without contacting. Then the deviation and inclination of the rotary axis are detected with high accuracy and adjusted automatically. Consequently, an error in plotting is prevented from being generated and the encoder which has the high accuracy and high resolution is realized.
