Claim 11

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; 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.

Claim 12

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; 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.
