To provide a character recognition device and parity check method capable of discriminating a recognition error in the recognition of a character other than figure.

Each segment of a character string 2 and a mark 3 is detected from the image read in a step S1 (step S29), and the respective totals of segments of the character string 2 and the mark 3 are calculated (step S3). The classification of even number/odd number of the segment total of the character string 2 and the classification of even number/odd number of the segment total of the mark 3 are determined (step S4), and whether both the classification are matched or not is determined (step S5), whereby the recognition error is determined. According to this, the discrimination of the recognition error can be executed when the character string 2 consists of alphabet characters other than figures.
