Claim One:
1. An optical character recognition system comprising: first memory means for temporarily storing an input character information read by optical scanning of a printed character on a paper in the form of a digitized data including background digital bits indicative of a paper white background area and character digital bits indicative of a character black data area; location normalizing means for normalizing a location occupied by said input character information on a storage plane of said first memory means; counting means for dividing said normalized input character information on said storage plane into a plurality of segments each having an area of 4.times.4 meshes, counting the number of character digital bit indicative meshes in each of said segments and generating the resulting count values as a set of segment information; subtracting means for subtracting 1 from each of said count values of said segment information set when the same is greater than 1; second memory means for temporarily storing as an input information a collection of said segment information for one character applied via said subtracting means; third memory means preliminarily storing permanently a set of standard character information representing a plurality of different characters in the same segment information form as the information form of said input information; matching means for performing the process of pattern matching between said input information and each of said set of standard character information; and decision means responsive to the result of said pattern matching process to determine whether said printed character is to be recognized as one corresponding to the most matched one of said set of standard character information or the same is to be rejected.
