Abstract
A scanning system comprising a cleaning apparatus for automatically cleaning originals prior to scanning and a dual mode scanner for scanning transmissive and reflective originals. The cleaning apparatus includes an ionizing dust remover and an electrically conductive brush assembly for sweeping dust and other foreign particles from the surfaces of the originals to be scanned.
Claims13
A scanning system for providing a digitized representation of an original, comprising:
- a displaceable scan carriage including an illumination module for illuminating a scan line on said original, a sensor system for obtaining a digitized representation of said illuminated scan line, and an optic system for focusing said illuminated scan line on said sensor system;
- means for displacing said original through said scan carriage along an object focal plane to obtain digitized representations of successive ones of said illuminated scan lines, said digitized representations of successive ones of said scan lines together comprising said digital representation of said original;
- means for determining whether said original is a transmissive original or a reflective original;
- and
- means, responsive to said determining means, for displacing said scan carriage to position said illumination module on a first side of said object focal plane when scanning a transmissive original, and to position said illumination module on a second side of said object focal plane when scanning a reflective original.

A scanning system for providing a digitized representation of an original, comprising:
- a vertically displaceable scan carriage including an illumination module for illuminating a scan line on said original, a sensor system for obtaining a digitized representation of said illuminated scan line, and an optic system for focusing said illuminated scan line on said sensor system;
- means for displacing said original horizontally through said scan carriage along an object focal plane to obtain digitized representations of successive ones of said illuminated scan lines, said digitized representations of successive ones of said scan lines together comprising said digital representation of said original;
- means for determining whether said original is a transmissive original or a reflective original;
- and
- means, responsive to said determining means, for vertically displacing said scan carriage in a direction substantially perpendicular to said object focal plane to position said illumination module on a first side of said object focal plane when scanning a transmissive original, and to position said illumination module on a second side of said object focal plane when scanning a reflective original.

- a displaceable scan carriage including an illumination module for illuminating a scan line on said original, a sensor system for obtaining a digitized representation of said illuminated scan line, and an optic system for focusing said illuminated scan line on said sensor system;
- means for displacing said original through said scan carriage along an object focal plane to obtain digitized representations of successive ones of said illuminated scan lines, said digitized representations of successive ones of said scan lines together comprising said digital representation of said original;
- means for determining whether said original is a transmissive original or a reflective original;
- and
- means, responsive to said determining means, for displacing said scan carriage to position said illumination module on a first side of said object focal plane when scanning a transmissive original, and to position said illumination module on a second side of said object focal plane when scanning a reflective original;
- wherein said original enters said scan carriage through a first entrance aperture and exits said scan carriage through a first exit aperture if said original is a transmissive original, and wherein said original enters said scan carriage through a second entrance aperture and exits said scan carriage through a second exit aperture if said original is a reflective original.
