摘要： A method and system for scanning comprises rotating a scanning chassis of an optical scanner to create an acute angle between the scan line and a scanning direction, such that the scanning chassis has two ends, and moving the scanning chassis in the scanning direction and with the acute angle between the scan line and the scanning direction, both two ends of the scanning chassis being moved in the scanning direction, while one of the two ends is moved more slowly than the other one so that the scanning chassis is made to be rotated with the acute angle.

摘要： A back-light module for an image scanning device includes a casing, a pair of tubular lamps, a light guide plate, and a frosted transparent plate. The image scanning device includes a document supporting plate and an optical scanning module movable in a longitudinal direction. A calibration of illumination with the back-light module is done by (1) activating the back-light module to project light onto the optical scanning module, (2) driving the optical scanning module in the longitudinal direction, (3) obtaining illumination signals associated with selected pixels of a longitudinally-extending calibration zone formed on the document supporting plate, (4) comparing each illumination signal with a reference to obtain a result and manipulating the result to obtain a calibration parameter, and (5) calibrating the illumination of pixels of an image with the corresponding calibration parameters in scanning a transmissive original document.

摘要： A vertically oriented image scanning device includes a chassis with a vertically oriented scanning window and a flap cover pivoted to the chassis. A document support flange is formed along a lower edge of the scanning window for aligning a document with respect to the scanning window. A thin metal plate has opposite edges attached to an inner face of the flap cover and forms a convex configuration for elastic deformation and thus applying a force to retain the document against the scanning window. The convex configuration also helps guiding the document to position. Alternatively, a resilient pad replaces the thin metal plate for applying a force to the document.

摘要： A reflection mirror support structure, applied to support a reflection mirror of an optical scanner. Using three points or a single point and a line to construct a plane, projecting rib and projecting point are formed on a carrier to hold the reflection mirror. The image distortion caused by bending the reflection mirror and twist deformation because of structures not being parallel to each other is improved.
