Claim Text:
1. A paper-sheet recognition apparatus that acquires information from a paper sheet and recognizes the paper sheet based on the information, the paper-sheet recognition apparatus comprising: one or more light emitting units, each of which includes a plurality of light sources and outputs n lights (n is an integer equal to or larger than 2) of different wavelengths therefrom; an emission-control program storage unit that stores a plurality of emission-control programs that have been created beforehand in order to obtain paper sheet images of different resolutions for respective lights concurrently, each resolution associated with information required for a purpose of a recognition of the paper sheet; an operation unit through which one of the plurality of emission-control programs is selected, an emission controller that performs emission control of the plurality of light sources of the light emitting units by executing the emission-control program selected through the operation unit; a line sensor that receives a light, which has been emitted from the light sources and then reflected from and/or transmitted through the paper sheet while the paper sheet is being transported; and a paper-sheet recognition processor that recognizes the paper sheet by using an optical signal received by the line sensor, wherein each of the emission-control programs includes instructions for the emission of the light sources, such that, in one emission cycle, a number of light emissions of at least one of the n lights differs from a number of light emissions of at least one of the other lights, and the one emission cycle is a cycle of illumination control of the plurality of light sources; and a resolution of a paper sheet image for each light is determined according to which of the plurality of emission-control programs is selected.
