3. The character recognition device in accordance with claim 2 , wherein: the non-corresponding-to-position information storage means stores therein, as non-corresponding-to-position information, a set of words that are not associated with the positional information and which includes at least one word equal to position corresponding information; and the non-corresponding-to-position information extracting means extracts non-corresponding-to-position information from the non-corresponding-to-position information storage means using as a key the position corresponding information extracted by the position corresponding information extracting means.
2. The character recognition device in accordance with claim 1 , comprising: non-corresponding-to-position information storage means for storing therein non-corresponding-to-position information that is words not associated with positional information; and non-corresponding-to-position information extracting means for extracting non-corresponding-to-position information from the non-corresponding-to-position information storage means according to the position corresponding information extracted by the position corresponding information extracting means, wherein the character recognizing means recognizes a character or a character string included in the image using the position corresponding information extracted by the position corresponding information extracting means and the non-corresponding-to-position information extracted by the non-corresponding-to-position information extracting means.
