Abstract
Using detectors, skewed conveyance of sheet media such as checks can be detected accurately regardless of whether part of the conveyed medium is folded over. The biased feed detection unitof a check processing deviceaccording to at least one embodiment of the invention determines the lengths Land Lof the conveyed check(STand ST) and the thickness of a folded part of the check(ST) at different positions perpendicular to the transportation direction based on the output of a paper thickness detectorand a length detectordisposed to the check transportation path. The folded length Lis then subtracted from the difference ΔL of the detected lengths to acquire a corrected difference ΔL(ST). If the corrected difference ΔLis less than or equal to a threshold value D, the medium is determined to be conveyed normally (ST). If the corrected difference ΔLexceeds the threshold value D, the medium is determined to be skewed (ST). Skewed conveyance of the checkcan thus be accurately determined.
