Abstract
The device for illuminating an original document in a copying machine in which the original document is properly illuminated both when it is in contact with a platen and when it floats above the platen. A main reflector is disposed around a light source to produce an arc of illumination directed toward the platen. A primary reflector disposed within the periphery of the arc reflects a first beam toward the platen while a floating-original reflector, also disposed within the periphery of the arc, reflects a second beam of light toward the platen in a direction so as to illuminate the original document within a predetermined range of distance from the platen.
