Abstract
A transparency adaptor is described that includes a flat panel illuminator within the scanner lid of the scanner. The flat panel illuminator provides backlighting for scanning transparencies, such that light passes through the transparency only once and into the scanner optics within the scanner base. When the flat panel illuminator is lit during a scanning process, the light source within the scanner is not lit. In a second embodiment, the flat panel illuminator is removeably attached to the scanner lid. Another alternative is for the flat panel illuminator adapter to be a separate from the scanner, such that it is placed over a transparent document when needed, either plugging into the scanner or a separate power source during the scanning process.
