Abstract
A scanning apparatus providing separate fixed object focal planes for transmissive and reflective original documents to be scanned, wherein a scan carriage containing illumination, sensor, and optical elements is moved together to scan an original document and to obtain a digitized representation thereof. The movable scan carriage has an illumination source disposed between the reflective and transmissive object focal planes, with the object focal plane to be used selected by changing the position of one or more optical elements within the scan carriage. A dark slide provides protection against flare during scanning, and can be closed to provide for dark current calibration as well as to seal the system from dust when not in use.
