PURPOSE:To make the reflection efficiency of light from an original by an exposure device nearly constant by forming the surfaces of a reflection plate at the parts not opposing to a traveling belt about flush to the surfaces of the traveling belt opposing to the glass plate surface. CONSTITUTION:An original P is disposed between a glass plate 7 which is a conveying supporting plate and plural traveling belts 8, and a reflection plate 11 is conveyed on the glass plate 7 in sliding contact therewith by the traveling of the belts 8. The reflection plate 11 disposed on the belts 8 projects to the glass plate 7 side in the parts not opposing to the belts 8 and the projecting surfaces thereof are roughly flush to the surface of the belts 8 opposing to the surface of the glass plate 7. Hence, each beam of the reflected light when the light from the light source of the exposure device reflects on the belts 8 and the reflection plate 11 does not cause any difference in optical path and the copy having no difference in density is obtained. |
