Abstract
An apparatus for determining the authenticity includes a light-emitting unit that emits a light including the first wavelength to the paper sheet; a first blocking unit that is arranged between the light-emitting unit and the paper sheet, and blocks off a light of a wavelength longer than the first wavelength; a light-receiving unit that receives a light including a second wavelength emitted from the paper sheet; a second blocking unit that is arranged between the light-receiving unit and the paper sheet, and blocks off a light of a wavelength shorter than the second wavelength. Finally, an authenticity determining unit determines an authenticity of the paper sheet based on the light received by the light-receiving unit.
