Abstract:
A high resolution optical scanner for use in a flat bed scanner housing including a platen having a scanning area upon which an object to be scanned is placed, said platen having a length dimension and a perpendicular width dimension, said scanner comprising:a carriage movably mounted beneath said platen and adapted to be moved reciprocally parallel to said length dimension; a plurality of mirrors mounted in said carriage; a lens mounted in said carriage; an image optical sensor for converting an object image into electrical signals representative of said image mounted in said carriage; a switch mirror rotatably mounted in said carriage and adapted to be positioned in a first position and in a second position; a first optical pathway defining an optical path from said platen to at least one said mirror and from said mirror to said switch mirror positioned in said first position and from said switch mirror to and through said lens to said optical sensor; a second optical pathway defining an optical path from said platen to at least one said mirror and from said mirror to said switch mirror positioned in said second position and from said switch mirror to and through said lens to said optical sensor; said first optical pathway adapted to focus upon said optical sensor a first portion of said scanning area; and said second optical pathway adapted to focus upon said optical sensor a second portion of said scanning area.
