Abstract

A banknote discrimination apparatus includes a plurality of photoelectric conversion elements in which an incident light including fluorescence emitted from a banknote irradiated with excitation light enters; a plurality of organic film filters that are arranged so as to overlap each of the plurality of photoelectric conversion elements, and have mutually different transmission bands; a circuit including a plurality of pixel circuits which are each connected to one corresponding element among the plurality of photoelectric conversion elements and output a pixel signal converted by each photoelectric conversion element in accordance with an intensity of the incident light that transmits through the organic film filter and enters to the photoelectric conversion element; a spectral processor; and a discriminator. At least one of the plurality of organic film filters is a filter obtained by overlapping two or more filter layers on each other.
