Abstract: A device includes a supporting mechanism which movably supports a living body, light sources which emit near infrared rays, an imaging unit which picks up venous images of the living body with light emitted from the light sources and an image processing unit which processes venous images picked up by the imaging unit, wherein the imaging unit picks up a plurality of still images consecutively from the living body which travels supported by the supporting mechanism and the image processing unit forms an image pattern of the living body by subjecting the obtained plurality of still images to processing.

Abstract: In a discrimination apparatus of the invention, a banknote or another paper as an object of discrimination is irradiated with ultraviolet radiation from an array of multiple ultraviolet-emitting LEDs. The ultraviolet radiation passes through a visible radiation block filter and is focused onto a preset site of the banknote by a lens. Multiple photodiodes are used to measure the transmitted light of ultraviolet radiation and the fluorescence, which is excited by the ultraviolet radiation from the banknote. The discrimination apparatus of the invention discriminates counterfeit banknotes from genuine banknotes, based on the observed pattern of the transmitted light over a preset range of the banknote. The technique of the invention desirably enhances the accuracy of discrimination in the discrimination apparatus that discriminates counterfeit banknotes from genuine banknotes.

Abstract: An object of the present invention is to increase a capability to determine bills determined as unidentified to improve a truth determination capability. A sheet handling apparatus of the present invention comprises: a detector that detects a characteristic of a sheet transported by a transport module; an amplifier that amplifies a signal obtained from the detector; an A/D converter that converts an analog signal amplified in the amplifier to a digital signal; determining means that determine the truth of the sheet by use of a signal having been produced as a result of A/D conversion by the A/D converter; and a control part that changes signal read accuracy of the detector. If a sheet is determined as unidentified in the determining means, the control part changes an amplification factor or resolution of the detector so that a capability to determine the sheet is higher, and the truth determination of the sheet is performed again.
