Abstract

PURPOSE:To obtain the original lighting device excellent in the durability with high performance, by enabling the high speed scanning of phototransmission body and avoiding the limitation of types of material of the phototransmission body, through the mechanical scanning lengthwise the original stand taking the phototransmission body as one body and through fixed lighting source. CONSTITUTION:The phototransmission body 11 which is scanned with a mechanical means along the lengthwise direction under the original stand 10 made of transparent glass, is provided. The original side end surface 12 of the body 11 is taken the same width or more as the original stand 10 to form it in slit shape, and it is located with a slope adjacent to the original stand 10 and located to the position receiving parallel light from the illumination light source 14 fixing the incident light end surface 13 at another end. Further, parallel light radiated from the illumination light source 14 fixed is received at the incident light end 13 moved with the body 11 scanned lengthwise the original stand 10, it is output to the original side end surface 12 through the body 11 to enable to illuminate the original surface on the original stand 10 for high speed scanning of the body 11. The body 11 is made of optical fibers and the like allowing to constitute the original lighting device with high durability.
