Abstract

The utility model discloses a dual-functional paper money tester, which is composed of a housing, an ultraviolet ray detection system and a magnetic induction detection system. The utility model can use the ultraviolet ray detection system to detect the bogus RMB with the fluorescence reaction and the bogus Hong Kong dollar or other tickets without the fluorescent secret mark, and can also use the magnetic induction system to detect the 50 yuan and 100 yuan bogus RMB without print point of magnetic ink printed after 1980. The utility model has the advantages of simple structure, convenient operation, reliable test result, low fabrication cost, etc. The utility model is particularly suitable for detecting the RMB with large denomination printed after 1980 in China, and can also detect any foreign paper money printed by magnetic ink, the Hong Kong dollar and some domestic tickets with fluorescent secret marks.

Description

Dual-funcitonal paper money tester

The utility model relates to a kind of instrument of checking bank note, the particularly a kind of detect counterfeit money machine that can debate other true and false bank note.

Known detect counterfeit money machine just adopts uviol lamp that bank note is detected, to differentiate its true and false.But, find on the market that recently the Renminbi of part forgery can't differentiate that in other words, existing uviol lamp detect counterfeit money machine has lost the reliability of the Renminbi of discerning the false from the genuine with uviol lamp.But the uviol lamp detect counterfeit money machine is still useful to differentiating Hongkong dollar and domestic some ticket.

The purpose of this utility model provides and a kind ofly can find two function detect counterfeit money machines of counterfeit money again with magnetic induction principle with ultraviolet ray.

The utility model is made up of shell, UV detection system and magnetic induction detection system three parts.Shell is made of last cover, housing, panel and bottom, last cover is positioned at the top of shell, become recessed lid shape, interior dress Ultraluminescence pipe, panel is positioned at the middle part of shell, be inclined in the top of housing, there is an external AC power supply on the right of panel, in order to the rocker type switch of control Ultraluminescence pipe, there is the push button DC power supply switch that belongs to electromagnetic induction system on the left side of panel, true and false pilot lamp, buzzer and the magnetic sensing head of red power light, green, bottom is positioned at lower housing portion, when battery being installed or checking in the housing various element, can open this bottom and operate; The UV detection system also has ac power plug and power lead, starter and ballast resistor except that above-mentioned ultraviolet fluorescent pipe and rocker type switch, the annexation of each element of UV detection system as shown in Figure 1; The magnetic induction detection system is except that above-mentioned magnetic sensing head, buzzer, power light, true and false pilot lamp, push button DC power supply switch, also have direct supply, electronic switch and level Four amplifier integrated package, the relation between each element of magnetic induction detection system as shown in Figure 2.

Using method of the present utility model and principle of work are as follows:

1, the fluorescence reaction of check bank note.At first press rocker type switch on the position of " opening ", to connect 220 volts of AC power, at this moment Ultraluminescence Guan Liang, then Renminbi or the Hongkong dollar that is printed on the fluorescence secret mark are placed on the panel, at this moment, some pseudo-Renminbi manifests reflective immediately, and the real Renminbi is the no-reflection phenomenon then; But true Hongkong dollar can manifest secret mark immediately on specific position--the numeral identical with denomination, pseudo-Hongkong dollar does not then have this secret mark.

2, the reaction of check magnetic.Because space of a whole page volume in 1980 is the Renminbi of 50 yuan and 100 yuan, privileged site overleaf adopts stronger magnetic ink printing, during check, at first pins the push button DC power supply switch with left hand.This moment, the power light of redness was bright, held with the right hand then

Renminbi and contact with magnetic induction head on the panel with the magnetic ink printing point that forefinger will be stronger, and firmly nuzzle up from inside to outside, as the reaction that is magnetic, then Magnetic Sensor sends signal to level Four computing integrated package immediately, this signal amplifies the back and triggers electronic switch, buzzer sends sound immediately, meanwhile, green true and false pilot lamp is bright, shows that it is genuine piece that this quilt is tested Renminbi, as there is not an above-mentioned reaction, show that then it is pseudo-product, after the check, unclamps the pushbutton switch that left hand is pinned, then turn-off direct supply, work for inspection finishes.

Advantage of the present utility model is as follows:

1, the part of present discovery there is not the pseudo-Renminbi of fluorescence reaction, can differentiate out reliably, can also differentiate foreign currency that all use magnetic ink printings or other domestic ticket;

2, easy and simple to handle, intuitive display;

3, cheap.Owing to adopt conventional electronic component, cost reduced greatly.

Below in conjunction with the description of the drawings, provide embodiment.

Fig. 1 is an appearance assumption diagram of the present utility model (bottom is pulled out state);

Fig. 2 is mounted inside figure of the present utility model;

Fig. 3 is the circuit diagram of ultraviolet detection system;

Fig. 4 is the frame principle figure of magnetic induction detection system.

A kind of two function cash inspecting machines are made up of shell, UV detection system and magnetic induction detection system, and shell adopts the iron sheet cover half punching press butt-joint moulding of 0.6 millimeters thick, are made of last cover (1), panel (2), housing (3) and lower cover (4); The UV detection system, adopt conventional fluorescent lamp circuit, use 220 volts of AC power, by 4 watts of ultraviolet light pipes (5), starter (6), ballast resistor (7), rocker type switch (8) and power lead and plug (9) are formed, wherein, 4 watts of ultraviolet light pipes (5) are installed on going up of recessed lid shape and cover (1) lining, starter (6) and ballast resistor (7) all are installed in the housing (2), rocker type switch (8) is installed on the panel (2), the magnetic induction detection system, use 3 volts of direct supplys, by magnetic sensing head (10), electronic switch (13) level Four computing amplifier integrated block and buzzer (14), power light (15), true and false pilot lamp (16), 3 volts of direct supplys (17) and push button dc switch (18) are formed by connecting by the principle of Fig. 4, level Four computing amplifier integrated block comprises change-over circuit (11) and amplifying circuit (12).

Claims

A kind of two function detect counterfeit money machines, form by shell and detection system, it is characterized in that in the detection system except that the UV detection system, also has one by magnetic sensing head (10), the level Four amplifier integrated block, electronic switch (13), hummer (14), power light (15), true and false pilot lamp (16), the magnetic induction detection system that direct supply (17) and push button dc switch (18) constitute, wherein, the level Four amplifier integrated block comprises change-over circuit (11) and amplifying circuit (12), after pressing the button formula dc switch (18), direct supply (17) is started working, power light (15) is bright, the signal elder generation of Magnetic Sensor (10) output is after electronic switch (13) is triggered in change-over circuit (11) and amplifying circuit (12) conversion and amplification back, and and then driving hummer (14) and true and false pilot lamp (16).
