Title:
PAPER SHEET IDENTIFICATION DEVICE AND PAPER SHEET IDENTIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/159517
Kind Code:
A1
Abstract:
A paper sheet identification device, wherein a differentiated reflected light image can be generated without leading to an increase in detection time. The operation of sensor units (20, 30) is divided into a plurality of phases and controlled. The plurality of phases include: a phase (reflected infrared 1) for detecting reflected light using an optical sensor (21) by allowing light to be radiated by a light-emitting unit (22a), and not allowing light to be radiated by a light-emitting unit (22b); and a phase (reflected infrared 2) for detecting reflected light using the optical sensor (21) by not allowing light to be radiated by the light-emitting unit (22a), and allowing light to be radiated by the light-emitting unit (22b). In at least one of these phases, light is caused to be radiated by a light-emitting unit (24), and transmitted light is detected by an optical sensor (31).
