ABSTRACT:
A scanning device comprises a paper holding member for holding paper to be scanned, paper feeder for continuously feeding the paper in a first direction at substantially a constant speed, scanning unit for scanning the paper in a second direction substantially perpendicular to the first direction, scanning areas scanned in two successive scanning cycles by the scanning unit being partly overlapped on each other, memory for storing data supplied from the scanning unit, and control unit for deriving column data each formed of a plurality of bits from the scanning unit at a regular interval for each row and sequentially storing the derived column data into the memory, detecting the overlapped bit number between two successive scanned data by comparing each column data of one of the two successive scanned data and corresponding column data of the other scanned data, and cancelling the detected number of overlapped bits from each column data of one of the two successive scanned areas.
