摘要： 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.

摘要： An apparatus for connecting electrical power to an exposure lamp in an image scanner in response to the detection of ambient light by a light sensor located under the scanner's cover. Such an apparatus provides an apparent reduction in exposure lamp warm-up time, with associated improvement in operator productivity, while minimizing exposure lamp operational life degradation and excessive energy consumption caused by leaving the exposure lamp turned on. Once the exposure lamp is turned on, a timing circuit is used in the preferred embodiment to disconnect electrical power from the exposure lamp so that if the scanner's cover is left open or closed, the exposure lamp will not be left on for excessively long periods of time.
