Patent ID: 7106480

Claim:
A scanning device comprising: a media holder for holding a medium to be scanned; an image capture module comprising: a reflecting surface, for reflecting an image of the medium; a pressure guide, for providing a pressure surface so that the image capture module maintains proper focusing during scanning, the pressure guide further comprising: a window, through which the image from the medium passes to the reflecting surface; a lens, through which the image reflected by the reflecting surface passes; and an image sensor, for capturing the image reflected by the reflecting surface and passed through the lens; an arm, attached to the image capture module, wherein the arm is attached to the image capture module by means of an arm tension device comprising: a fulcrum to which the image capture module is attached and allowing rocking of the image capture module; and a tension mechanism which provides a pressure on an end of the image capture module, pushing the pressure guide onto the media holder; a light source attached to the arm, for providing a light to penetrate the medium during scanning; a threaded screw mechanism, for providing a drive force for the image capture module and arm; and a threaded mount, attached to the arm and threaded onto the treaded screw mechanism so that when the threaded screw mechanism turns, the threaded mount moves accordingly so as to move the image capture module and arm forward and backward during operation.
