Description
Technical field
The utility model relates to a kind of device that is used to discern printing or written character, relates in particular to a kind of device of realizing differentiating false Renminbi, and the utility model device is suitable for being engaged in domestic and international bank and non-bank's use of cash bank settlement business.
Background technology
The general two big classes of dividing of false Renminbi are promptly forged Renminbi and adulterium Renminbi.Forge Renminbi and mean, use various utensils, equipment, technological means, all class false tickets, coin such as illegal imitated again mechanism, duplicating, inscription rubbing according to former states such as genuine note paper, pattern, watermark, safety lines; And the adulterium coin means that utilizing the counterfeit money of various forms method with the abnormal appreciation of genuine note, form is the correction amount of money, pieces together nominal value, mends pattern by replacing a damaged part, peels off and take off page or leaf etc.Till now, the GB16999-1997 of China " Renminbi discriminating machine for fake RMB " national standard has only proposed the discriminating requirement to counterfeit money, adulterium paper money is not proposed any discriminating requirement as yet.
At present, the false distinguishing mode that generally adopts on point, the cash inspecting machine has: false distinguishing modes such as magnetic, safety line, infrared, fluorescence; As the patent No. is 01235558 Chinese utility model patent, discloses the cash inspecting machine that has counterfeit identifying functions such as magnetic, safety line, infrared, fluorescence.Magnetic false distinguishing principle of work is to adopt Magnetic Sensor to collect and record the magnetic signal at magnetic position on the genuine notes in this cash inspecting machine, and converts thereof into electric signal, distinguishes after amplification and comparison process; Safety line false distinguishing work principle is to adopt the safety line sensor to collect and record the material and the enciphered message of safety line on the genuine notes, and converts thereof into electric signal, distinguishes after amplification and comparison process; Infrared false distinguishing principle of work is to adopt infrared sensor to collect and record the light characteristic that infrared printing printing ink is shown in the specific region on the genuine notes under the infrared excitation of specific wavelength, and converts thereof into electric signal, distinguishes after amplification and comparison process; It is stronger that fluorescence false distinguishing principle of work is that the purple light that adopts violet source to send shines on the counterfeit money fluorescence reflection, fluorescence reflects more weak this physical characteristics on the genuine notes and shine, collect and record the reflected fluorescent light of counterfeit money, and convert thereof into electric signal, after amplification and comparison process, distinguish.
In recent years, printing fake money was the sudden huge profits industry of the world today, also was the tumour of the world today.Along with science and technology development, the technology that prints fake money also develops into grouping of the world economy, intellectuality, the high-technicalization of today from the imitative formula of original work, manual formula.Recently constantly good, the foot of the image fidelity that occurs, feel has illustrated and has made pseudo-group to the degree of going deep into of genuine notes research and the high-new degree of used technology in the counterfeit money of mixing the spurious with the genuine.Because the false proof measure of Renminbi genuine notes machine readable initiative very little, this provides convenience to the fake producer undoubtedly, has increased the difficulty of effective false distinguishing.Particularly in recent years, the setter of counterfeit money, three passes hands after the principle of work of having found out paper money counter, fake-identifying instrument, utility model adulterium paper money, adulterium paper money is in brief: by piecing together, mend by replacing a damaged part, take off means such as page or leaf, the part of genuine notes is transplanted on the counterfeit money, the part of counterfeit money is transplanted on the genuine notes, is made it to become the adulterium paper money that contains the counterfeit money composition, thereby reach the purpose of the profit of appreciating.The puppet adulterium paper money that the fake producer will remain with genuine notes machine readable initiative anti-counterfeiting characteristic removes to deceive fake-identifying bank-note counting machine, cash inspecting machine, automatic cash dispenser even banknote cleaning-sorting machine to bank.The anti-counterfeiting characteristic (as watermark, color shifting ink denomination numeral etc.) that genuine notes are recognized for user's naked eyes moves on on the counterfeit money deceitful to the ordinary consumption place.Bank gathering, deposit facility are constantly infected, and large and small retailer receives pseudo-adulterium paper money repeatedly by mistake, the inactive automatic cash dispenser of some banks occurred, much consume the trouble waters that 50,100 yuan of denomination big-tickets dare not be received in the place.
Generally speaking, raising along with dummy people's currency system technology for making, fidelity strengthens, and the leakage of conventional false distinguishing modes such as the magnetic that adopts in the existing cash inspecting machine, safety line, infrared, fluorescence distinguishes that rate and mistake distinguish that rate is progressively improving, and can not adapt to the needs of the false Renminbi of current identification fully.
