[Claim for Utility Model Registration] An image in which the original is scanned in the longitudinal direction of a line sensor, and the original is scanned several times in a plane-sequential manner by relatively moving the original in the sub-scanning direction perpendicular to the main scanning direction. The reading device extracts a characteristic specific line from the read line output when reading for the first time, stores information on this specific line and the number of lines from the start of reading to the specific line, and At the time of reading following reading, the read line output and the information of the specific line stored by the storage means are compared, and if the two are similar, the number of lines from the start of reading to this point and the information stored in the storage means are compared. An image reading device characterized in that the read line is corrected in accordance with the difference between the number of lines and the number of lines stored at the time of initial reading.
