Abstract

light reflected from the document propagates through the mirror and lens, to the photoreceptor through the exposure slit. To add to the illuminating light, the exposure slit adjacent to the photoreceptor is made reflective. The slit transmits part of the image light and part would be reflected back into the system, "recycled" as it were for use as object illuminating light.
