Abstract:
A digital scanner for scanning a sheet document comprising:a curved transport path along which said documents travel; a transport mechanism for moving said document along said transport path; a platen having upper engagement surface, a leading edge and a trailing edge; a sensor for digitally capturing an image on said document which is transported past said platen; a first guide surface in said transport path adjacent said leading edge and a second guide surface in said transport path adjacent said trailing edge, said first guide surface and said upper engagement surface forming a first air gap, and said upper engagement surface and said trailing edge forming a second air gap as said document passes said platen, said first and second guide surfaces having a kinetic coefficient of friction of less than about 0.30; and a pressure applying member capable of applying substantially uniform pressure on said document at said platen along the width of said document.
