Claims

[Scope of utility model registration request]

(1) A light emitting body that converts mechanical stress into light is optically connected to a predetermined section of the optical fiber, either continuously or intermittently, and a part of the light emitted by the stress is confined in the optical fiber and transmitted. An optical position detection device comprising a plurality of light receivers at the open ends of the optical fibers, and the position where stress is generated can be determined from the ratio of the amounts of light detected by the light receivers.

(2) The optical position detecting device according to claim 1, which is a utility model, in which an optical fiber is formed with microbending with a partial pitch.
