Title:
PAPER SHEET IDENTIFICATION DEVICE, AND PAPER SHEET PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/009953
Kind Code:
A1
Abstract:
A paper sheet identification device according to the present disclosure detects fluorescence and phosphorescence emitted from a transported paper sheet, the paper sheet identification device comprising: a light source that emits excitation light at a paper sheet; a light source control unit that controls the light source so that the excitation light is emitted during an illumination period, and is extinguished in a extinguishing period after the lighting period; a light-receiving unit that outputs a fluorescence and phosphoresce detection signal based on the light given off from the paper sheet during the illumination period, and outputs a phosphorescence detection signal based on the light given off from the paper sheet during the extinguishing period; a calculation unit that, in the fluorescence and phosphorescence detection signal, calculates an estimated phosphorescence signal value that is estimated to be the signal value based on the phosphorescence received by the light-receiving unit from the paper sheet; and an identification unit that identifies the paper sheet on the basis of the estimated phosphorescence signal value.
