Fig. 2 shows the one-piece construction of an embodiment of the present invention.Upper casing 1 is formed the currency examine shaft of a writing brush type body that can grip with lower casing 12,3 flat head screws 4 are fixed on the loudspeaker 2 on horn hood 3 and top thereof in the upper casing 1, circuit board 6 is control processing circuit that 3 integrated circuit etc. are formed, the cylinder of LED lamp 16 is erected at the front portion of circuit board 6, pushbutton switch 7 and feature button 8 is housed below the circuit board 6; Selection push button 17 and three toggle switches 18 of also having the side dress, 2 circular holes are arranged on the sensor circuit plate 19, be provided with 2 violet light diodes 20 and 1 phototriode 21 below, sensor circuit plate 19 is fixed from lower casing 12 outside screw-ins by 2 screws, 2 wear-resisting stickers 29 stick on lower casing 12 anterior outsides, cover 2 screws, flat head screw 23 is with right spacer 24, anti-dazzling screen 25, optical filter 26 and left spacer 27 are connected and fixed, magnetic head gum cover 22 is sleeved on the induction magnetic head 28, be fixed in the front portion of lower casing 12, circuit board 6 is fixed in lower casing 12 by 3 flat head screws 5, negative spring 9, anodal spring 10 be connected spring 11 and all be located on the lower casing 12; Flat head screw 13 is by fixing with upper casing 1 and lower casing 12 in the battery compartment, and battery compartment holds No. 7 batteries 14 of 2 joints, battery cover 15 capping battery compartments.
In above-mentioned numeral voice currency examine pen, control processing circuit is the 46R22R integrated circuit by model, speech IC AP18108A, amplifier integrated package LM324 and relevant electron device are electrically connected to form, in speech chip, write corresponding alarm voice program, wherein the pin 1 of 46R22R is connected with the middle bay of three toggle switches, pin 2 is connected with the Renminbi shelves of testing of three toggle switches, pin 3 is connected with the U.S. dollar shelves of testing of three toggle switches, pin 4 is connected with magnetic head by amplifying circuit, be used for receiving processing magnetic head detection signal, pin 5 is connected with bi-colour LED respectively with pin 6, pin 8 is connected with two phototriodes respectively with pin 9, pin 12 is connected with violet light diode (LED2), pin 19, pin 20, pin 21, pin 22 is connected with speech IC AP18108A respectively, and other pin is connected with function element respectively.
When using currency examine, can be placed on the desktop selecting push button be chosen on the corresponding Currency Type gear, banknote must being faced up simultaneously earlier, object can not be magnetic under the desktop.
If detection Renminbi, at this moment the photoconductive structure assembly is obtained the fluorescence parameter (wavelength of fluorescence, amplitude) of Renminbi key position, detects the magnetic parameter (duration of magnetic, amplitude and pulse number) of safety line simultaneously by the magnetic capture component.Microprocessor by high-speed and high-efficiency carries out the consistency synchronization judgement to fluorescence parameter and magnetic parameter then.As shown in Figure 4, can will select push button to transfer on the corresponding gear earlier, pin function key, detection head is aimed at denomination position and this machine of moving right, and streak the position of " 0 " in the nominal value numerical value on the banknote, if the voltage that the photosensitive reception head in the left side (phototriode) reception is returned is lower than minimum fluorescence magnitude of voltage and just illustrates that this machine has moved to phosphor dot, carry out magnetic intensity then and judge.Amplify magnetic intensity by amplifying circuit, voltage after amplifying amplifies magnitude of voltage greater than minimum magnetic and illustrates that this machine examination measures qualified magnetic intensity, if the duration of magnetic is less than the time of measuring effective fluorescence, and produce the magnetic pulse number in the regulation numerical range, be genuine Renminbi, at this moment the green light in the currency examine bi-colour LED is luminous, and it is " really " speech explanation that alarm sends simultaneously, represents that then this coin is genuine; If this machine moves photosensitive reception head in the zone of regulation, receive the voltage of returning and continue to illustrate that greater than minimum fluorescence magnitude of voltage this Renminbi is counterfeit money; If magnetic intensity amplifies back voltage and continues to amplify magnitude of voltage less than minimum magnetic, illustrate that this Renminbi is counterfeit money; If magnetic intensity is qualified, but the duration less than the time of measuring effective fluorescence, illustrate that this Renminbi is counterfeit money; If magnetic intensity is qualified, but the pulse number that produces illustrates that greater than magnetic pulse number regulation numerical value this Renminbi is counterfeit money; Red light in the currency examine bi-colour LED is luminous at this moment, and alarm sends " vacation " speech explanation simultaneously, represents that then this coin is " vacation ".
If detect dollar, at this moment the purple light parameter (amplitude of purple light) that reflects of U.S. dollar, by the magnetic parameter (wavelength of magnetic, amplitude and pulse number) of magnetic capture component to privileged site, the microprocessor by high-speed and high-efficiency carries out true and false judgement to purple light parameter and magnetic parameter then simultaneously.As shown in Figure 5, can will select push button to transfer on the corresponding gear earlier, pin function key, detection head is aimed at denomination position and this machine of moving right, and draw to position shown in the dashed middle line of banknote, if the voltage that the photosensitive reception head in the right (phototriode) reception is returned reaches unsettled magnitude of voltage and illustrates that this machine is unsettled, the photosensitive voltage that reception is returned that receives in the right illustrates that less than minimum value this machine is placed on the underproof bank note.If being placed on, this machine just begins to carry out magnetic intensity and pulse number judgement on the qualified bank note, criterion is as follows, the mistiming of two adjacent pulses is less than special time, arrived the detection completing place if exceed the special time explanation, enter the judgement of docking the pulse number of getting back then, if the magnetic pulse number is true dollar in specialized range, at this moment the green light in the bi-colour LED is luminous, it is " OK " speech explanation that alarm sends simultaneously, represents that then this coin is genuine; Otherwise be false dollar, at this moment red colored lamp is luminous in the bi-colour LED, and alarm sends " NO " sound simultaneously, represents that then this coin is " vacation ".
This currency examine pen can also adopt manual mode to detect banknote, can select push button transfer in the middle of on the gear, this machine is placed on can detects coin apart from coin top 2 centimeters whether fluorescence is arranged.If in addition this machine is placed on the coin, move to can detect on the coin sequence number and whether be magnetic, if be magnetic, this chance is sent the sound of " BI ".
