Abstract
An optical illumination device for a copying apparatus which includes a light source, a series of reflectors, and a light detecting member for detecting the amount of light reflected off of the original document to control the intensity of the light source. The series of reflectors includes two reflectors on the opposite side of the optical path from the light source which are integrally formed to provide an L-shape configuration in cross section. One of the integrally formed reflectors reflects the light from the document onto the light detecting member.
