Abstract: PROBLEM TO BE SOLVED: To smoothly pass a paper to be scanned by providing a preceding blade and a following blade consisting of an upper part and a lower part, inclining them toward a scanning window, and separating them from the scanning window. SOLUTION: The body part 88 of a scanner contains a flat bed window 24 and an image sensor 22 for detecting the light reflected by a scanned paper. A scanning part F or part 99 is a paper guide part for automatically feeding a paper to be scanned to the scanner. The effective scanning part F is determined by the other scanning window 25 made of a resistant transparent material. One paper P has an upper surface 21U and a lower surface having a following blade (left blade) 21L inclined on two sides of the scanning window 25 and a preceding blade (right blade) 21R. The lower end of the blade 211 forms a step in the scanning window, and the preceding right blade 21R forms a coplanar connection with the scanning window 25. According to this, a smooth passage for paper is formed.

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.

Abstract: A scan window (25) made of a transparent material for exposing a paper (p) to a light source. A paper guide includes two guiding plates. A right plate (21R) and a left plate (21L) are arranged next to the scan window (25). The right plate (21R) and the left plate (21L) have their lower sides facing the scan window (25). The paper (p) runs over the scan window (25) in a smooth flow. An Independent claim is included for: (a) a scanner for dual use as a flat bed scanner and for scanning with automatic paper feed
