Abstract

The utility model relates to a multi-purpose forged paper money identifying device, which is composed of a light control switch circuit, an oscillating circuit, a light and sound alarm circuit, a power circuit, a purple light tube driving circuit, a purple light tube, a photosensitive probe head, a casing body, a lamp head seat, a transparent window and a retroreflection sheet. Because the photosensitive probe head is used for detecting the retroreflection quantity of paper money, when the forged paper money is discovered, the oscillating circuit is triggered to start to oscillate through the light control switch circuit so as to drive the light and sound alarm circuit to send out a light and sound alarm. The utility model has the advantages of legerity and agility. The cost is low. The utility model can be used in a hand-carry or a desktop mode, and can also be matched with a paper money counting machine.

Description

Multi-purpose forged bank note identifying device

The utility model relates to a kind of recognizer, particularly a kind of counterfeit money recognizers of using more.

Disclose a kind of counterfeit money recognizer in the Chinese patent (patent No. 90220120.4), it adopts portable mode, uses more convenient, but its when judging counterfeit money as long as the interior eye that can choose judge, not accurate enough reliably, easy appearance is judged by accident and is broken.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art and provides a kind of easy to use, and meets the counterfeit money recognizers of using that counterfeit money can send sound and light alarm more.

The purpose of this utility model can reach by following measure: a kind of counterfeit money recognizers of using more, comprise power circuit, purple light tube drive circuit, purple light pipe 7, housing, bulb socket, transparency window, reflecting piece, it is characterized in that: also have light-controlled switching circuit, oscillatory circuit, luminous warning circuit, audible alarm circuit, photosensitive probe, light-controlled switching circuit is visited its output driving oscillatory circuit work of signal that photosensitive probe is sent here, oscillatory circuit a kind of delivers to luminous warning circuit, and the audible alarm circuit is delivered on another road.

The purpose of this utility model can also reach by following measure: photosensitive probe is loaded on the pedestal part of housing, the rigging position correspondence of this purple light pipe, and power switch K and potentiometer W1 are loaded on the carrying handle part of housing.The base stage and the potentiometer W1 that are loaded on triode BGC2 in interior photoresistance R of photosensitive probe and the light-controlled switching circuit join, the collector of triode BC2 joins by 1 end of phase inverter F1 in phase inverter F1, diode D5 and the oscillatory circuit, the pin of phase inverter F5 joins by the base stage of triode BC3 in resistance R 4 and the luminous warning circuit in the oscillatory circuit, and joins by the base stage of triode BC4 in resistance R 5 and the audible alarm circuit.

Fig. 1 is a functional-block diagram of the present utility model;

Fig. 2 is a shape assumption diagram of the present utility model;

Fig. 3 is an electrical schematic diagram of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, Fig. 2, the utility model is made up of light-controlled switching circuit 1, oscillatory circuit 2, luminous warning circuit 3, audible alarm circuit 4, power circuit 5, purple light tube drive circuit 6, purple light pipe 7, housing 8, bulb socket 9, photosensitive probe 10, transparency window 11, reflecting piece 12 etc.Photoresistance R is loaded in the photosensitive probe 10, and 10 of photosensitive plugs are loaded on the pedestal part of housing 8.Its position and 7 contrapositions of purple light pipe.Utilize the reaction of counterfeit money blue light,, thereby send sound and light alarm by the detectable reflective amount of photosensitive probe.Potentiometer W1, power switch K then are loaded on the carrying handle part of housing 8; Wiring board 13 and reflecting piece 11 all are loaded in the housing 8.

With reference to Fig. 3, light-controlled switching circuit is made up of photosensitive tube R ', potentiometer W1, triode BC2, phase inverter F1, diode D5 etc.; Oscillatory circuit 2 is made up of phase inverter F2～F5, capacitor C 3, C4, resistance R 2, R3, diode D5 etc.; Luminous warning circuit 3 is made up of triode BC3, luminotron LED etc.; Audible alarm circuit 4 is made up of triode BC4, loudspeaker Y etc.; Power circuit 5 is made up of rectifier bridge 2, capacitor C 1, C, triode BC1, voltage stabilizing diode DC, diode D1 etc., and purple light tube drive circuit 6 is made up of diode D2～D5, capacitor C 5～C8, R6～R7 etc.

During real work, press power switch K, the purple light plumber does, simultaneously～and the 220V power supply provides direct supply for circuit after 2 rectifications, C2 filtering, DC, BC1 voltage stabilizing.Under the irradiation of purple light, genuine note does not have fluorescence reaction, counterfeit money then plays fluorescence reaction, show dazzling blue light, as this light meeting trigger triode BC2 after photosensitive probe is surveyed, and the output of BC2 triggers the oscillatory circuit of being made up of phase inverter F2～F5 by F1, makes its starting of oscillation, outputting oscillation signal shows thereby make LED and loudspeaker Y send sound and light alarm.Adjust the sensitivity that potentiometer W1 can adjust triggering.

When this device being made portable check banknote, can shine apart from banknote 3～5 cm heights; This device also can be installed on the paper money counter or do desk-top use.

The utility model has following advantage compared to existing technology: uses lightly flexibly, but sound and light alarm when finding counterfeit money, it is convenient and swift to differentiate counterfeit money; And cost is lower, is easy to popularize, and is applied widely.
