Abstract
PURPOSE: To reduce the weight of a traveling part by attaining tolerance to a noise, by connecting a photodetector on the traveling base body to a fixed main part via optical fiber.
CONSTITUTION: Photodetector 12 and electronic circuit 13 are fitted to main body 14 which never moves and on traveling base body 16 moving along rail 15, optical circuit system 17 is mounted. Light beam 18 to be detected emitted from optical circuit system 17 enters optical fiber 19 and is led to photodetector 12 fitted to main body 14. Since the diameter of the section of a light beam is greater than that of the core of the optical fiber, quard lens 43 consisting of focusing type fibers 39W42 is used to lead light beams, incident to respective fibers, to optical fibers 44W47.
