Abstract
A paper sheet identification device that detects a stain on a paper sheet and identifies the stained condition of the paper sheet includes an area memory () that stores therein in advance an area where a stain is to be detected on the paper sheet as a target detection area, a pixel number memory () that stores therein in advance the number of pixels of an image printed on the target detection area as the reference number of pixels used as a reference value when being compared, an image reading unit () that, based on the target detection area stored in the area memory, reads an image on the target detection area from the paper sheet, a pixel-number detection unit () that detects the number of pixels in the image read by the image reading unit as the number of read pixels, and a calculation unit () that calculates a stain value that indicates a stained condition on the target detection area of the paper sheet, by comparing the number of read pixels detected by the pixel-number detection unit with the reference number of pixels stored in the pixel number memory.
