Abstract
An automatic paper feeder uses a paper guide with two separate lower blades for feeding the paper past a scan window. The separate blades provide smooth passage of the paper over the scan window and avoiding rubbing the scan window surface. When the paper feeding mechanism is used both for automatic paper feeding scanning and for flat-fed scanning, the image sensor position is changed for the two applications, because the former scan window lies over the larger scan window for flat bed scanning and the elevations of the scanned papers for the two situations are different. The vertical position of the image sensor can be changed to maintain equal distance between the scan surface and the image sensor.
