Patent ID: 7186967

Claim:
An optical transducer for converting status of objects to electric signals, comprising: a light emitting unit for emitting light; a light detecting unit for converting incident light to said electric signals; plural optical sensor heads selectively coupled to said light emitting unit and said light detecting unit, and bridging gaps respectively assigned to said objects with said light so as to supply said incident light representative of said status of said objects to said light detecting unit; a frame having a route immovable with respect to said light emitting unit, said light detecting unit and said plural optical sensor heads; plural optical fibers connected between said light emitting unit, said light detecting unit and said plural optical sensor heads, and having respective warped-end portions connected to at least either said light emitting unit and light detecting unit or said plural optical sensor heads so as to be resiliently held in contact with said at least either said light emitting unit and light detecting unit or said plural optical sensor heads; and a fastener keeping said plural optical fibers stable on said route.
