Claims

[Claims for Utility Model Registration] (1) A recognition unit that cuts out a character pattern from quantized image data of a form, recognizes the cut out character pattern, and outputs the recognition result; A character recognition device comprising a post-processing section that performs post-processing on recognition results and outputs the results of the post-processing, wherein information on the position of blanks between adjacent character patterns is obtained from the cutting positions of the character patterns; A dictionary selection unit is provided that detects a word break for one unit of post-processing based on the position information of the space between characters, and outputs selection information of a word dictionary according to the word break, and the post-processing unit is connected to the selection unit. A character recognition device comprising a post-processing unit that selects a word dictionary based on information. (2) The character recognition device according to claim 1, wherein the dictionary selection unit is a dictionary selection unit that detects an inter-character space having a maximum length among inter-character spaces as a word break. (3) The dictionary selection unit compares the difference in length between spaces between adjacent characters with a predetermined threshold, and detects spaces between characters when the difference in length is equal to or greater than the threshold as a word break. 2. The character recognition device according to claim 1, further comprising a dictionary selection section.
