Problems solved by technology

However, because these high-tech anti-counterfeiting marks are difficult to identify with the naked eye, it is difficult to quickly distinguish between true and false, so that criminals still have opportunities to take advantage of them.
In order to solve the problem that traditional banknote detectors cannot recognize these high-tech anti-counterfeiting marks, I focus on research and use polarized light devices to directly observe polarized invisible marks printed on banknotes, and have obtained ZL00220757.5 No. new banknote detector and the Chinese patent of ZL00221339.7 arbitration banknote detector, but due to the large size of these two patented products, they are mainly suitable for fixed places
In order to reduce the volume, a portable banknote detector of patent No. ZL01237306.0 was designed. Although its volume is much smaller than that of the desktop banknote detec

Embodiment Construction

[0008] See attached figure 1 , 1 in the figure is a laser diode, 3 is a purple light diode, 2 is a shooting polarized light-emitting tube, 4-6 is a current limiting resistor, 7-9 is a power switch, 10 is a DC power supply, and 11 is an external power socket. The laser diode 1, the purple light diode 3 and the shooting polarized light emitting tube 2 are respectively connected to the DC power supply through the current limiting resistor 4-6 and the power switch 7-9. attached figure 2 It is a structural schematic diagram of a shooting type polarized light-emitting tube. 21 in the figure is a light-emitting diode, 22 is a housing, 23 is a polarizer, and 24 is a light-transmitting glue. Packaged in the housing 22. Due to the successful development of the shooting type polarized light-emitting tube, the traditional separate polarizing device is changed into an integrated polarized light generating device as small as a crystal triode, because the volume of the three light-emittin...

Abstract

The invention is a kind of widespread money-checking device, which mainly made up of laser diode, a ultraviolet diode, a firing polarization luminotron, a current limiting resistance, a power switch and a direct current power, the laser diode, the ultraviolet diode, the firing polarization luminotron and the firing polarization luminotron are connected to the direct current power through the current limiting resistance and the power switch. Because of using the firing polarization luminotron whose size likes a transistor, the volume of the product volume likes a match box; it can check out the hidden label, it is convenient, and simple.

Description

technical field [0001] This patent relates to a device for checking genuine and counterfeit banknotes, in particular to an easy-to-use popular banknote checking device that is as small as a matchbox and can be carried by everyone, and belongs to the field of checking banknotes. Background technique [0002] Due to repeated bans on counterfeiting activities, all countries are vigorously cracking down on the manufacture and sale of counterfeit banknotes. At the same time, they are also constantly adding high-tech anti-counterfeiting marks on new banknotes. ) and photoluminescent hair color (WFF) and other invisible anti-counterfeiting marks are enough to distinguish genuine coins from counterfeit coins, so that people will keep counterfeit coins out, which is an effective way. However, because these high-tech anti-counterfeiting marks are difficult to identify with the naked eye, it is difficult to quickly distinguish between true and false, so criminals still have opportuniti...
