Abstract
PURPOSE: To enhance the utilization efficiency of light and perform good lighting by providing a box type flurorescent lamp whose faces other than projecting face are made mirror faces and providing focusing type optical transmission bodies which receive the reflected light from the radiated surface of the light projected through the reflecting plate.
CONSTITUTION: Focusing type optical transmission bodies 8 of plural array configurations supported to a frame body 7 while being positioned between the contact glass 5 on which the original 4 is placed and a photoreceptor 6 are provided. A reflecting plate 10 is provided in diagonal opposition to the illuminated part 8 opposing to said optical transmission bodies 8. Further, a box type flurorescent lamp 11 is provided in diagonal opposition to this reflecting plate 10. This fluorescent lamp 10 comprises coating fluorescent coating 13 on the inside surface of a sealing glass plate 12 and forming a mirror face 15 through a aluminum evaporation or the like on the other faces 15 except one face 14 opposing to the reflecting plate 10. This enables the utilization efficiency of light to be improved and good lighting to be performed.
