Abstract
A digital scanner for scanning sheet document along transport path. The scanner includes a transport mechanism for moving the document along the transport path and a platen. The transport path is designed to minimize sticking or jamming of the document at the platen and for providing a high quality digital scan of the document.
Claims11
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.

A digital scanner for scanning a sheet document comprising:
- a curved transport path along which said documents travel, the transportation path has a radius of curvature of about four inches (10.16 cms);
- 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.
