Abstract

PURPOSE:To perform accurate character segmentation while eliminating the need for the precise arrangement of a CCD array by holding correction data regarding the position of the CCD array in advance and by correcting readout picture data by the correction data. CONSTITUTION:At right angles to the running direction of a sheet 4, CCD arrays 1 and 2 are provided. As correction data, the extent B of an offset from the right-end sheet running reference line 3 of the array 2, the extent W of an overlap between the arrays 1 and 2, extents D1 and D2 which correspond to inclinations of the arrays 1 and 2, and the extent C of a shift between the centers of the arrays 1 and 2 are measured. The obtained correction data are stored in a correction data memory 11 in a picture correcting circuit 20. Then, picture data read by a reading circuit 12 in normal sheet reading operation is corrected by a correcting circuit 13 and then a segmentation recognizing logical circuit 14 recognizes a character picture.
