End 4
A cylindrical body 18 having a flange 18a surrounding the entire circumference of b is fixed to the boss portion 1b with screws 19.
These cylindrical bodies 16 and 18 are covers that have a light shielding effect. These cylinders 16 and 18 prevent external light from affecting the light transmitting section 12, light receiving section 13, light input end 4a, and light output end 4b, or prevent light from the light transmitting section 12, etc. from leaking to the outside. It can be prevented.
