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.
