Abstract
A bill discriminating apparatus for a bill handling machine including an ultraviolet ray lamp for emitting ultraviolet rays toward bills, a light detector for photoelectrically detecting visible light emitted from phosphor materials contained in bills upon being irradiated with ultraviolet rays and producing visible light detection signals, a visible light detection signal amplifier for amplifying the visible light detection signals produced by the light detector, an ultraviolet ray detector for photoelectrically detecting ultraviolet rays emitted from the ultraviolet ray lamp and producing ultraviolet ray detection signals, a CPU for receiving the visible light detection signals amplified by the visible light detection signal amplifier and the ultraviolet ray detection signals produced by the ultraviolet ray detector and discriminating bills, the CPU adjusting an amplifying factor of the visible light detection signal amplifier in accordance with levels of ultraviolet ray detection signals input from the ultraviolet ray detector. According to this bill discriminating apparatus for a bill handling machine, it is possible to discriminate a denomination of a bill and whether or not a bill is acceptable with high accuracy.
