Abstract
A curved reflector is disposed behind an elongated lamp for reflecting light from the lamp onto a document carrier in the form of a narrow elongated beam. The carrier is movable perpendicular to the beam for scanning a document placed on the carrier. One or more orifices are formed through the back of the reflector and a blower creates an air flow through the orifice and around the lamp for cooling the same.
