Abstract
An amount of a read position error in the subscanning direction between line image sensors (for example, CCD1, CCD2, CCD3) is obtained by initially scanning and reading a correction read pattern (6a, 6b). In scanning of an original, output image signals from the line image sensors (CCD1, CCD2, CCD3) are relatively delayed by a line number corresponding to the amount of the read position error between the line image sensors (CCD1, CCD2, CCD3), to correct time difference, caused by the read position error, in information reading in the boundary portion of the line image sensors. An arrangement of line memories is also provided for correcting angular deviations of the line image sensors.
