ABSTRACT:
A scanning apparatus providing separate fixed 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. The resolution of the digitized representation of the scanned original document can be determined by rotation of at least one lens about an axis substantially perpendicular to its optic axis.
