PURPOSE:To prevent optical fiber flux from being folded by the humidity of optical fiber elements by guiding and setting up a hot light guide for irradiating light to heat and dry the optical fiber elements into a part in which the optical fiber flux is inserted. CONSTITUTION:An endscope 1 is constituted of an operation part 2, an insertion part 3 and a flexible light guide cord 4. The 3rd optical fiber flux 15 constituting the hot light guide transmitting heating light is inserted into the insertion part 3, one projected leading end 16 is arranged on this side from a curved tube 6 and the other projected leading end 15 is set up in the curved tube 6 so that light is irradiated to the parts of the 1st and 2nd optical fiber flux 13, 14 arranged in the curved tube 6. Light incident from a lamp to the 3rd optical fiber flux 15 is projected from the projection leading end 16 into the curved tube 6 of the insertion part 3 to irradiate the parts of the 1st and 2nd optical fiber flux 13, 14 arranged in the curved tube 6. Since the light includes infrared- rays, water condensed on the optical fiber flux 13, 14 is evaporated. |
