Abstract: PURPOSE:To transfer light very efficiently without leaking the light from fibers, by inserting a bundle of many light guide fibers, made of the same transparent material, into a transparent coating tube having a low refractive index. CONSTITUTION:A bundle of many light guide fibers 1 made of the same transparent material and having a relatively high refractive index is inserted into a transparent, flexible synthetic resin tube 2 having a lower refractive index than that of the fibers 1; and both terminal parts 2a and 2a are fixed with a tranparent adhesive and fibers 1 are freely movable in the tube except at both the terminal parts 2a and 2b. Light incident into fibers 1 from the incidence terminal surface 3 of the terminal part 2a is totally reflected repeatedly by the boundary surface of an air layer A at a noncontact part except contact points (a) of the fibers 1 to reach the other terminal side 2b, and light is incident to adjacent fibers 1 without being reflected at contact points (a) to reach the other terminal side 2b similarly as mentioned above. At contact points (b) between the fibers 1 and the tube 2, the light in fibers 1 is totally reflected and transmitted to the other terminal side 2b to be led out of a projection terminal surface 4.

The quantity of the light is much when the surfaces of the pipes have the indicated color but becomes minute in the case of a color other than the indicated color.  The current converted by the converter is binarized by a binarizing circuit 19 corresponding to the magnitude thereof and the CPU 2 outputs 0V or 5V and it is judged that the fusion of the plastic pipe 13a or 13b is improper in the case of 0V and proper in the case of 5V.
