PAPER SHEET RECOGNITION APPARATUS, LIGHT GUIDE AND LIGHT GUIDE CASING FOR USE IN SPECTROMETRIC MEASUREMENT OF PAPER SHEET

摘要

A paper sheet recognition apparatus that recognizes a paper sheet based on optical characteristics of the paper sheet is proposed. The paper sheet recognition apparatus includes at least one light source that emits a light toward the paper sheet; a light-guiding member that receives any of reflected lights reflected from plural regions on the paper sheet and transmitted lights that have passed through plural regions on the paper sheet because of emission of the light on the paper sheet from the light source, condenses the received lights, and outputs the condensed light from a light outputting section; an optical processing unit that generates spectral distribution from the condensed light output from the light outputting section of 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.

主权项

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 receives 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 a part thereof; 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.
