Abstract:
An apparatus for double-sided scanning of a paper document comprising:a. a first image scanner having a first sensor field of view directed in a first direction and a first scanner sensor port surface through which an image is viewed and across which a document passes and said first image scanner having first and second opposing ends; b. a second image scanner having a second sensor field of view directed in a second direction opposite said first direction and having a second scanner sensor port surface through which an image is viewed and across which a document passes and said second scanner is diagonally offset with respect to the first image scanner and said second scanner having third and fourth opposing ends; c. a first pinch roller having a first axle about which it rotates and a first gear member attached to an axle end of said first roller where said first axle is parallel to the first scanner sensor port surface and the first pinch roller is positioned in a tangentially contacting orientation with respect to the first sensor port surface; d. a second pinch roller having a second axle about which it rotates and a second gear member in a mating relationship with said first gear member and attached to a second axle end of the second pinch roller where said second axle is parallel to the second scanner sensor port surface and the second pinch roller is positioned in a tangentially contacting orientation with respect to the second sensor port face; e. a first z-bracket having a pivoting point in a central portion of the z-bracket and having first and second extensions where the first and second extensions are mounted to the first and third ends of the first and second scanners, fixing the first and second scanners at diagonally opposed positions and said z-bracket is adapted to rotate about said pivoting point where pivoting increases or decreases a pressure contact between the first and second sensor port surfaces and the first and second pinch rollers; and f. a drive means adapted to drive said first gear member where said second gear member will follow for advancing the media to be scanned.
