ABSTRACT:
An inspection device includes a light source emitting ultraviolet light onto a banknote conveyed on a conveyance path, a light source emitting infrared light onto the banknote, a photosensor for detecting light from the banknote, a light source control processing portion for controlling the light sources while individually switching the light sources at high speed, and a discrimination processing portion. The discrimination processing portion first imports each of two detection signals (output signals) from the photosensor, which are obtained by substantially within an identical period of time when the banknote is illuminated with the light through sequential lighting of the light sources and calculates an output ratio of the photosensor. Then the calculated output ratio of the photosensor is compared and collated with reference data preliminarily stored in a memory, determining authenticity and denomination of the banknote.
