Abstract
The document scanner of the present invention includes a reading assembly of simple, compact and light-weight construction. The reading assembly includes an optical system having a relatively short focal length. The reading assembly is thus simply configured in a compact manner close to the document to be scanned. The optical system is also configured to extend in a particular direction beyond the document viewing area for improved resolution of images from a bound document adjacent the binding. The reading assembly further includes a compact and light-weight illumination source which is low in power consumption, and thus, may be powered by batteries. The stand-alone document scanner of the present invention is particularly suited to portability.
