ABSTRACT:
A transparent adapter hinged to a flatbed scanner for the scanning of a transparency or negative, including a hot cathode-ray tube to provide light, a refractor mounted around the hot cathode-ray tube to refract light from the hot cathode-ray tube onto a document, for permitting the image of the document to be picked up by a charge-coupled device in the optical scanner, and to prevent light from being directly projected by the hot cathode-ray tube onto the document.
