Abstract

The present invention relates to a popular type banknote verifying machine which mainly comprises a laser diode, a purple light diode, a shooting type polarization luminous pipe, a current limiting resistor, a power supply switch and a direct current power supply, wherein the laser diode, the purple light diode and the shooting type polarization luminous pipe are respectively connected with the direct current power supply through the current limiting resistor and the power supply switch. Because the present invention uses the integration shooting type polarization luminous pipe which is as small as a transistor, the size of products is as small as matchboxes. The present invention has the advantages of small size, can verify various hidden marks in an all-weather mode, can be simply and conveniently used as flashlights, is carried about and used by everyone, etc. The present invention is a popular type banknote verifying machine with strong discriminating power, can cause everyone to identify false banknote, cause false banknote not to be circularly used, cause falsifiers to be unable to make false banknote and is a popular type banknote verifying product which is urgently needed in China and is helpful to maintain normal financial orders.

Description

Popular detect counterfeit money machine

Technical field

This patent relates to a kind of device of checking true and false banknote, and the popular banknote tester easy to use that little as matchbox everybody of particularly a kind of volume can both carry belongs to the field of checking bank note.

Background technology

Because the fraud activity remains incessant after repeated prohibition, each state is all when hitting manufacturing energetically and peddling counterfeit money, also constantly on new edition bank note, increase the anti-counterfeiting mark of high-tech content, these anti-counterfeiting marks such as optic metachromatic sign (OVI), polarization type concealed sign (PFF) and photoluminescence color development invisible anti-counterfeit marks such as (WFF) are enough to and genuine note and counterfeit money difference can be come, people are kept outside of the door counterfeit money, are a kind of effective ways.But because the anti-counterfeiting mark light of these high-tech contents is difficult to identification with naked eyes, true and falsely be difficult to rapid differentiation, make that the law-breaker is still organic to be taken advantage of.I can not discern the problem of these high-tech anti-counterfeiting marks in order to solve traditional cash inspecting machine, primary study also utilizes the polarized light device can observe directly the money identifier that is printed on polarization type concealed sign on the banknote, and obtained the Chinese patent of ZL00220757.5 new edition money identifier and ZL00221339.7 number arbitration money identifier, but, mainly be applicable to fixed-site because the volume of these two patented products is bigger.In order to reduce volume, designed the portable money identifier of ZL01237306.0 patent again, though its volume is littler many than desk-top money identifier, but because of its polarising means is traditional magazine formula optical devices, need shine polarisation concealed sign place at a certain angle with playing the back downside appropriate location that the polarisation source is contained in magazine, form at the preceding top of the magazine installation analyzing camera lens that leaves on the reflected light path of the suitable distance of reflection spot again, for the ease of from the analyzing camera lens, observing the polarization type concealed sign, the analyzing camera lens can not be too little, add that the analyzing camera lens need be contained in the magazine both sides respectively and apart from each other with a polarisation source, so it is littler that its volume has been difficult to, also need simultaneously banknote is placed in the magazine and could checks, use also inconvenience, be difficult to the universal effect that realizes that everybody has.

Summary of the invention

The purpose of this patent is in order to overcome the weak point of above-mentioned money identifier, design a kind of volume very little, have can both check under light or the unglazed situation concealed sign, easy to use as torch, everybody likes carrying the popular detect counterfeit money machine of use.

The popular detect counterfeit money machine of this patent mainly utilizes the check counterfeit money concealed sign that is difficult to copy and discerns true and false banknote, its structure comprises laser diode, violet light diode, Shoot type polarized luminescence pipe, current-limiting resistance, power switch and direct supply, and described laser diode, violet light diode and Shoot type polarized luminescence pipe are connected with direct supply with power switch through current-limiting resistance respectively.Described Shoot type polarized luminescence pipe is the key that this patent is used to check the polarization type concealed sign, it also is the new device of developing for the present invention, can directly send the polarized light that can make the hidden polarization sign manifest direct visual identification, its structure comprises light emitting diode, housing and polaroid, and described polaroid is contained in LED front area and is encapsulated in the housing with printing opacity glue.

The popular detect counterfeit money machine of this patent, can have under light or the unglazed situation can both be by check genuine notes ticket on distinctive multiple concealed sign differentiate true and false, during use, take banknote on the other hand, another hand take detect counterfeit money machine as torch according to banknote, connect the power switch of Shoot type polarized luminescence pipe, suitably adjust angle, the polarized light that sends with Shoot type polarized luminescence pipe illuminates the hidden polarization sign place on the banknote, can directly see the polarization type concealed sign on the banknote, as show " 100 " with the nominal value equivalence, " 50 ", " 10 ", the banknote of numerals such as " 5 " is a genuine note, otherwise is counterfeit money.The concealed sign of the laser inspection photoluminescence color development that also available laser diode sends is checked fluorescence labelling with the purple light that violet light diode sends.Because three luminescent device volumes are all very little, power consumption is also very little, can select the minicell power supply for use, switch also can be selected microswitch for use, can make volume little as matchbox, have volume little, can round-the-clock check concealed sign, easy to use as torch, everybody likes carrying advantages such as use, is the very strong popular detect counterfeit money machine of a kind of discriminating power.Can form everybody and can both discern counterfeit money, counterfeit money can't be circulated, the fake producer does not have sky and can bore, and helps safeguarding normal financial order.

Description of drawings

Accompanying drawing 1 is a kind of structural representation of this patent;

Accompanying drawing 2 is structural representations of Shoot type polarized luminescence pipe in this patent.

Embodiment

Referring to accompanying drawing 1, among the figure 1 is laser diode, the 3rd, violet light diode, the 2nd, Shoot type polarized luminescence pipe, 4-6 is a current-limiting resistance, and 7-9 is a power switch, the 10th, and direct supply, the 11st, external electric supply socket, described laser diode 1, violet light diode 3 and Shoot type polarized luminescence pipe 2 are connected with direct supply with power switch 7-9 through current-limiting resistance 4-6 respectively.Accompanying drawing 2 is structural representations of Shoot type polarized luminescence pipe, and 21 among the figure is light emitting diodes, the 22nd, and housing, the 23rd, polaroid, the 24th, printing opacity glue, described polaroid 23 are contained in light emitting diode 21 fronts and are encapsulated in the housing 22 with printing opacity glue 24.Because succeeding in developing of Shoot type polarized luminescence pipe, change traditional separate type polarising means into little incorporate polarized light generating means as transistor, the volume of three luminescent device 1-3 of cause is very little, power consumption is also little, can select minicell 10 power supplies for use, also can power through socket 11 usefulness external power supplys, switch 7-9 also can select microswitch for use, make small product size little as matchbox, it is very convenient to portably use, recognition capability to counterfeit money is strong, is a kind of general product that helps safeguarding national financial order.
