Optical sensor

摘要

An optical sensor includes a light source, a characteristic light-guiding member, a characteristic changing part which changes the optical characteristic of light, and a detecting unit which detects the light having the optical characteristic changed by the characteristic changing part and guided by the characteristic light-guiding member. The optical sensor includes a control member which inhibits at least the twisting of the characteristic light-guiding member, and controls a bending state of the characteristic light-guiding member, and a positioning mechanism which positions the characteristic changing part with respect to at least a circumferential direction of the characteristic light-guiding member.

1. An optical sensor comprising:
a light source configured to emit light; a characteristic light-guiding member configured to guide the light emitted from the light source; a characteristic changing part which is provided in the characteristic light-guiding member and configured to change the optical characteristic of the light in accordance with how much the characteristic light-guiding member is bent; a detecting unit configured to detect the light having the optical characteristic changed by the characteristic changing part and guided by the characteristic light-guiding member; a control member which provided along the characteristic light-guiding member, configured to inhibit at least the twisting of the characteristic light-guiding member, and controls a bending state of the characteristic light-guiding member; and a positioning mechanism which holds the characteristic light-guiding member and the control member and positions the characteristic changing part with respect to at least a circumferential direction of the characteristic light-guiding member accompanying holding.
