Description

Multifunctional pocket descriminator for counterfeit money

The utility model relates to a kind of currency detector, the multi-functional currency detector of pocket.

Existing commercially available counterfeit money identification device, mostly be the professional desktop computer that uses for bank, shop, big unit greatly or cooperate coupling with paper money counter, volume is big, price is high, misclassification rate is higher, must use in the place that civil power is arranged, usable range is restricted, be difficult for carrying therefore difficult popularizing again.

The patent No. 91217628.8 " two function detect counterfeit money machines " also is a kind of desk-top detect counterfeit money machine that will have civil power to work.

The purpose of this utility model is to provide a kind of pocket multi-functional currency detector, and use in the place of wanting of can in officely what is the need for, and is not had or not the influence of civil power, and usable range is wide, and is easy to use, flexibly, can carry again.

The utility model is achieved in that the detection system that is made of upper and lower cover and light, magnetic detection circuit (being called for short lamp inspection circuit and magnetic inspection circuit down) forms, and positive source passes through toggle switch K _1-1, the one tunnel through R ₂And D ₄Ground connection, the road is through R in addition ₃, C ₁Ground connection is again through R ₄An and termination IC of magnetic head ₁3 pin, magnetic head are held ground connection, C in addition ₂Be connected in parallel on the magnetic head two ends, IC ₁1 pin one tunnel through R ₇, C ₃And connection IC ₂5 pin, the road is through R in addition ₆Connect 2 pin through R ₅Ground connection, IC ₂7 pin, one route C ₄Lotus root splice grafting IC ₃10 pin, route R in addition ₁₀Connect 6 pin through R ₉Ground connection, R ₁₁One end ground connection, a termination 10 pin, IC ₃8 pin one tunnel through D ₆, R ₁₄Connect 12 pin, in addition route R ₁₃Connect 9 pin through R ₁₂Ground connection, R ₁₅With C ₅A termination 12 pin in parallel, an end ground connection, IC ₄14 pin through D ₅Ground connection, 4 pin connect positive source, and 11 pin ground connection constitute magnetic inspection circuit;

Positive source meets transformer B ₂Simple L ₁End of the same name, the collector of termination BG in addition, base stage meets L ₂End of the same name and C ₆One end, C ₆In addition end and grounded emitter, L ₂End is through R in addition ₁₆Connect positive source, transformer B ₂The L of the inferior utmost point ₃Termination toggle switch L of the same name _1-2, termination fluorescent tube L constitutes lamp inspection circuit in addition.

Fig. 3. the left view of Fig. 1.

Fig. 4. schematic circuit of the present utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Fluorescent tube is that two extension lines are connected on respectively on the circuit board (9), is embedded in ultraviolet light (8) L in lower cover (12) top groove _a, be placed on fluorescent light (4) L under the interior glass plate of loam cake (1) (3) _b, entangle with circular rubber at ultraviolet light (8) two ends.Glass plate (3) is inserted for milky and is embedded in loam cake (1) surface groove, and pilot lamp (2) is φ 3D ₁, D ₄, D ₅Light emitting diode, toggle switch (5) K _1-1, K _1-2Be 2 * 4 toggle switches, battery (10) is a rechargeable battery, and transformer (11) is charging transformer B ₁, the indentation, there that lens (13) are fixed on lower cover (12) below with bearing pin is used to differentiate that the part of thing amplifies the explanation true and false.

On loam cake (1) inwall isolation bar is arranged, respectively toggle switch (5), magnetic head (6), charging assembly (7), battery (10), transformer (11) are laid and be fixed in the isolation bar by position shown in Figure 2.

Circuit and lamp inspection circuit that magnetic inspection circuit is formed for adopting integrated circuit LM324N also have R in addition ₁With D ₁, D ₂With battery E, D ₃All be fixed on the circuit board (9) with the charge power supply circuit that is connected in parallel on the secondary formation of transformer (11) after battery E ' connects, circuit board (9) is screwed on the fixed leg of loam cake (1).

Lower cover (12) is combined on the loam cake (1) and is screwed identifier and is assembled into.

During use if there is civil power charging assembly (7) can be inserted socket, with toggle switch (5) K _1-1, K _1-2Push a, a ₁The position is that identifier is in charged state, and external circuit disconnects, transformer B ₁Secondary induction goes out 6 volts of alternating voltages, and this voltage is added in R ₁And D ₁On, make charging indicator light (2) D ₁Luminous (green), and respectively through D ₂, D ₃Be rectified into dc pulse moving voltage and give battery E, E ' charging, E, the E ' external circuit supply of connecting during work.

When using the magnetic inspection, with toggle switch (5) K _1-1, K _1-2Push b, b ₁The position, this moment, cell voltage passed through K _1-1Be added in R ₂And D ₄On, make magnetic inspection pilot lamp (2) D ₄Luminous (Huang), identifier promptly are in magnetic inspection state.The be magnetic position of feature of bank note to be detected is closely contacted with magnetic head, and friction fast, if magnetic head induction output signal, this signal is through IC ₁3 pin homophases amplify, by the output of 1 pin, then through R ₇, C ₃Lotus root is closed, through IC ₂The input of 5 pin is carried out the 2nd time and is amplified, and is exported through C by 7 pin ₄Every directly being added to IC ₃10 pin amplify for the 3rd time, at last by IC ₄Body moves pilot lamp (2) D ₅Luminous (red), then illustrating tested is genuine note, if not luminous or entire paper coin can both be luminous, then explanation is a counterfeit money.

If will examine, with toggle switch (5) K with lamp _1-1, K _1-2Push C, C ₁The position is ultraviolet light L _aWork, magnetic inspection circuitry cuts is by R ₁₆, BG, C ₆, B ₂The light testing circuit of forming is at L ₃Two ends induce high-frequency alternating voltage and make ultraviolet light L _aWork explanation true and false bank note is in like manner with toggle switch (5) K _1-1, L _1-2Push d, d ₁The position makes fluorescent light L _bWork, the watermark in the identification bank note.

The utility model is compared with prior art: have or not civil power to work, the no limitation scope of application is wide. Have charging device that the local available civil power charging of civil power, power supply, easy to use, flexible are being arranged, volume is little, in light weight, power consumption is little, highly sensitive, discrimination is high. Not only can use for unit, also can be for the individual, carry when family goes out, at any time use, measuring ability is many, and lens can local amplification detection, and fluorescent lamp is used for detecting the watermark on the bank note, provides cheap and good-quality testing tool for hitting the personation counterfeit money.
