    • A handy scanner equipped with rollers in a lower surface of a bottom plate thereof includes a bank portion protruding downward from the lower surface of the bottom plate and provided to surround a periphery of an FAP protruding downward from the same lower surface such that the FAP does not contact with a surface of an original. Downward protruding distances of the bank portion and rollers are determined such that at least a portion of the bank portion and the rollers can contact with a surface of an original simultaneously and, preferably, a difference in vertical level between lower ends of the bank portion and the FAP is set such that CTF of the handy scanner becomes 30% or more.
    • 在底板的下表面配备有辊的便携式扫描仪具有从底板的下表面向下突出的堤部,其设置成包围从同一下表面向下突出的FAP的周边,使得FAP 不接触原件的表面。 确定堤部和辊的向下突出距离,使得堤岸部分和辊的至少一部分可以同时与原件的表面接触,并且优选地与堤岸部分和辊的下端之间的垂直水平差异 设置FAP使得便携式扫描仪的CTF为30%以上。
