Claim Text:
1. A paper sheet recognition apparatus that recognizes a paper sheet based on optical characteristics of the paper sheet, the paper sheet recognition apparatus comprising: at least one light source that emits a light toward the paper sheet; a light-guiding member that includes a plurality of light receiving sections and a light outputting section, the plurality of light receiving sections receiving any of reflected lights or transmitted lights from plural regions on the paper sheet irradiated with the light from the light source, condenses and guides the received lights to the light outputting section; an optical processing unit that generates spectral distribution from a light output from the light-guiding member; and a recognition processing unit that recognizes the paper sheet based on a feature of the spectral distribution generated by the optical processing unit wherein the optical processing unit generates the interference fringes from a light output from the light-outputting section of the light guiding member, and the recognition processing unit recognizes the paper sheet based on a feature of the interference fringes generated by the optical processing unit.
