DOCUMENT SORTING DEVICE, CHARACTER READER, GENUINENESS JUDGING DEVICE AND METHOD FOR THESE

摘要

PROBLEM TO BE SOLVED: To speedily and precisely sort a document by using the fast and precise collation of a character string. SOLUTION: Picture data of a slip including a character string is fetched from a picture input device 1 and stored in a picture storing part 21. A slip position detecting means 31 detects the position of the slip in the stored picture data. In accordance with this detecting result, a coordinate transformation means 32 transforms the coordinate system of coordinates where the character string has to be positioned in the slip stored in a coordinate storing area 22a to the picture coordinate system being the coordinate system of the picture data. The deviation of the coordinates of the character in the picture data stored in the part 21 is corrected by the unit of the character string by a character string coordinate value correcting means 33 and by the unit of the character by a character coordinate value correcting means 34. A graphic collation means 35 extracts the feature quantity of each character in picture data whose coordinates are corrected and collates it with a collating featured value stored in a collating feature storing area 22b. In accordance with this collating result, an output device 9 outputs the code information on each character stored in a code information storing area 81a.
