ABSTRACT:
The present case is directed to a number of illumination systems making use of lamps and reflectors having predetermined optical configurations and arranged to insure minimal glare in the eyes of an operator using the equipment in which the illumination systems are incorporated. A first version involves a stationary paraboloid reflector cooperating with a moving parabolic cylinder reflector to illuminate an original document during a copying operation. In a second version, the moving reflector is split into two reflectors each having distinct parabolic configurations and different focal lengths. In still another version, only a single reflector is arranged for movement during scanning of an original document to project a line of light and has a predetermined configuration which is paraboloid in one direction and substantially elliptical in a direction transverse to the first direction.
