Abstract
The utility model relates to a counterfeit money recognizer which is provided with a half enclosed housing, an open type test port, a comparison testing light sample plate with graduation marks, external light source and incandescence light source, wherein, the external light source and the incandescence light source are mutually independent. The counterfeit money recognizer can not only remarkably concentrate ultraviolet light field, but also can avoid interference of the stray light source from the outside. The counterfeit money recognizer can also prevent ultraviolet light from injuring eyes of operators effectively. The counterfeit money recognizer is a multifunctional counterfeit money recognizer with novel structure, accurate detection, and convenient operation. The counterfeit money recognizer can quickly detect the authenticity of fluorescence hidden codes, bank note sizes, watermark patterns and paper characteristics of the bank notes, securities, bonds or otherwise similar valuable bank notes, and noble paper pieces.
Description
The utility model relates to check banknote, security, bond or the authenticity device of valency bank note is similarly arranged, and relates in particular to a kind of discriminating machine for fake RMB.
Existing check bank note authenticity device, great majority all are to discern its true and false by observing bank note in the fluorescence reaction under the ultraviolet excitation." the counterfeit money recognizer " and " counterfeit money discriminating alarm " announced respectively as Chinese patent CN2074034U and CN2130274Y, all more convenient practicality, but, they are had relatively high expectations to working environment, to external world the antijamming capability of source of stray light a little less than, in addition, their function singleness restricts its widespread use.
The utility model is intended to overcome above-mentioned deficiency provides a kind of follow-on discriminating machine for fake RMB.
The purpose of this utility model is achieved by the following technical programs.It comprises shell, banknote sightingpiston and the front illuminated ultraviolet source on it, with the wiring board that is provided with the ultraviolet source start-up circuit, it is characterized in that: shell is type semienclosed, open and close angle and make the kermesinus of light shield or black loam cake and cross section and be spill by changing arbitrarily so that detect a mouthful housing that is open type and form, tilting banknote sightingpiston in the shroud notch front is that the comparison of a band scale mark detects the printing opacity model, and its back side is provided with the incandescent source separate with ultraviolet source.
The utility model is provided with the semi-closure type shell of kermesinus or black light shield, promptly can concentrate the ultraviolet light field significantly, increase effect, can avoid the interference of extraneous source of stray light again preferably, make detection accurately and reliably, can also prevent effectively that ultraviolet light from damaging operating personnel's eyes.Be provided with the detection mouth of open type, can be conveniently examined laying and collecting of banknote, improve detection speed.Be provided with comparison and detect the printing opacity model, can intuitively detect the true and false of nominal value size apace, and be provided with separate ultraviolet source and incandescent source, can detect fluorescence private mark, nominal value size, watermarking images and the papery of banknote respectively.Be a kind of novel structure, accurate, the easy to operate multi-functional discriminating machine for fake RMB of detection.It is not only applicable to differentiate the true and false of banknote, also is applicable to differentiate variously valency, valuable paper spare to be arranged as security, bond or the true and false of valency bank note and valuable certificate etc. is similarly arranged.
Fig. 1 is the profile synoptic diagram;
Fig. 2 is a side view.
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
The embodiment shell is that light shield (1) and housing (2) are formed by loam cake, adopts the kermesinus injection molding.Comparison detects printing opacity model (3) and makes of 3 millimeters thick sheet glass, on become to be printed with the ticket size scale mark (6) of 10 yuan of Renminbi, 50 yuan and 100 yuan.The ultraviolet light tube power of ultraviolet source (4) is 4 watts, and optical wavelength is 3650 ± 5 dusts.Incandescent source is with exchanging 220 volts, 8 watts small electric bulbs.
When being used to differentiate counterfeit money, earlier that loam cake (1) is open, to be examined banknote again is placed on above the comparison detection printing opacity model (3), connect ultraviolet source gauge tap (8) then, ultraviolet source (4) sends the ultraviolet light front illuminated and is examined on the banknote under the control of the start-up circuit on the wiring board (5), nominal value fluorescence private mark manifests immediately.If extraneous source of stray light is disturbed big, can adjust the switching angle of loam cake (1), make fluorescence private mark clear display, so that accurately differentiate.The scale mark (6) that utilizes comparison to detect on the printing opacity model (3) can be to the discriminating of comparing of nominal value size.Under UV-irradiation, the aura of blue light tone appears in nominal value, shows that the banknote papery is pseudo-goods.Be used further to refer to push the fine motion gauge tap (9) of incandescent source 7, can estimate watermarking images at par, unclamp finger, incandescent source 7 also closes, and detects and finishes, and disconnects ultraviolet source gauge tap (8), and loam cake (1) is resetted.
Claims (1)
1, a kind of discriminating machine for fake RMB, comprise shell, banknote sightingpiston and the front illuminated ultraviolet source on it, with the wiring board that is provided with the ultraviolet source start-up circuit, it is characterized in that: shell is type semienclosed, be spill so that detect a mouthful housing that is open type and form by changing the loam cake that opens and closes angle double as light shield and cross section arbitrarily, tilting banknote sightingpiston in the shroud notch front is that the comparison of a band scale mark detects the printing opacity model, and its back side is provided with the incandescent source separate with ultraviolet source.
