    Abstract: A flat bed scanner having a transparent platform and a scanning mechanism is provided in the present invention. The transparent platform is used to support the objects that wait for scanning. The scanning mechanism is movably placed under the transparent platform along the length direction of the transparent platform. The scanning mechanism includes a plurality of LEDs, a camera lens and a CCD. The LEDs are arranged in a line along the width direction of the transparent platform. The scanning mechanism further includes a diffuser that is placed over the LEDs and has the same width with the transparent platform, and the diffuser diffuses the light beams radiated from the LEDs and then projects the light beams being diffused over the objects that wait for scanning.

    Abstract: An optical scanner system wherein the central region of the light source is selectively covered up by a mechanically actuated shutter during a transparency scanning mode. By occluding the central portion of the light source, problems with flare and degraded image quality are eliminated. The shutter is actuated to its two positions (normal reflective mode position, transparency mode position) by pins, protrusions, or the scanner walls in the scan module path. When the scan module is driven to the extremes of its travel the shutter is either driven open or closed. A bracket structure is provided to hold the transparent media and a covering light reflective tent, and can include the pin or pins that can protrude into the scanner module path and thus actuate the shutter only when the structure is mounted on to the scanner by the user. The bracket structure can include a lower member that rests directly on the platen glass to align filmstrips, slides, and other transparent media. The tent structure is hinged relative to the lower structure which allows it to be opened and closed to enable insertion of transparent media. When the tent structure is closed it acts as the reflective light path to allow light from the primary light source to be reflected up, over, and down through the transparent media, and into the optical light path leading to the optical sensor.
