Paper-sheet recognition apparatus, paper-sheet processing apparatus, and paper-sheet recognition method

摘要

A paper-sheet recognition apparatus includes a banknote recognition sensor (11) including one or more light emitting units that output first to n-th lights (n is an integer equal to or larger than 2) of different wavelengths and a light receiving unit that receives a component of light, which has been emitted from the light emitting unit and then reflected from and/or transmitted through a paper sheet; an emission controller (15) that performs emission control of the light emitting units; and a banknote judgment processor (16) that recognizes the paper sheet by using an optical signal received by the light receiving unit. The emission controller (15) performs the emission control of the light emitting units such that the number of light emissions per one emission cycle with respect to each of the first to n-th lights differs depending on information to be acquired from the paper sheet.
