Abstract

Fluorescent substances having similar peak wavelengths for fluorescence excited by irradiation of excitation light are to be detected in distinction. In order to solve this issue, a UV_LED irradiates excitation light to a leaf of paper, a first light-reception unit receives light having a first wavelength range that includes the peak wavelength of fluorescence excited by a fluorescent substance due to irradiation of excitation light, and a second light-reception unit receives light emitted from the same area as the area on the leaf of paper that emitted light to be received by the first light-reception unit, said light having a second wavelength range that is positioned near the first wavelength range. Then, a fluorescent substance specifying unit specifies the type of fluorescent substance added to the leaf of paper on the basis of outputs from the first light-reception unit and the second light-reception unit, and an evaluation unit evaluates whether the leaf of paper is genuine or counterfeit on the basis of the result evaluated by the fluorescent substance specifying unit.
