Abstract
PURPOSE: To reduce the quantity of light sources for lightingof a color copying machine radiating plural points by providing a plurality of reflecting plates around direct tube type light sources and radiating plural points simultaneously.
CONSTITUTION: Radiation light from direct tube type light sources 17, 17 radiates a slit 13 via reflecting plates 21, 22, 24 and a slit 15 via reflecting plates 21, 22, 24 and at the same time it radiates a slit 14 via reflecting plates 18, 18. Hence, the slits 13 thru 15 at 3 points provided with required filters, atc. of the color image copying machine are radiated. As a result, the quantity of light sources for lighting is reduced and highly efficient lighting by small power may be performed.
