Abstract

PURPOSE: To simply increase the accuracuy of measurement, by using solid grid plate holder.
CONSTITUTION: On the rotary grid plate 9 fixed to the rotary shaft 5 fitted via the bearing 6 on the base 4, the fixed grid plate holder 10 providing the photo detection element 15 and arm 16 is inserted and it is held with the nut 11, and the fixed grid plate 12 is fixed on it. Thus, the light from the light emitting element 13 on the base 4 is projected through the lens 14 and incident to the photo detection element 15 via the rotary grid plate 9 and fixed grid plate 12. Further, with the use of the fixed grid plate holder 10, the eccentricity between the rotary shaft 5 and the drive shaft 7 is avoided from being affected for the rotary grid and the fixed grid position relation, and with the latch of the stopper 17 placed on the arm 16 and the bese 4, the movement of the fixed grid plate 12 toward the revolution of the rotary grid plate 9 is restricted, the periodic variation due to the eccentricity of the rotary shaft 5 is reduced to achieve the desired purpose.
