Abstract
PURPOSE: To enhance the utilization rate of light and perform good lighting by providing a box type fluorescent lamp whose faces other than projection face are made mirror faces and providing focusing type optical transmission bodies which receive the reflected light from the surface radiated by this projected light.
CONSTITUTION: Focusing type optical transmission bodies 8 of plural array confuigurations 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 box type fluorescent lamp 10 is provided in diagonal possition to the illuminated part 9 in opposition to these transmission bodies 8. This fluorescent lamp 10 comprises coating fluorescent coating 12 on the inside surface of a sealing glass plate 11, and forming a mirror face 15 through aluminum evaporation or the like on the other faces 14 except one face 13 opposing to the illuminated part 8. This enables the utilization efficiency of light to be improved and good lighting to be performed.
