Next, specify in the paper money identifier of identification forge or true or paper money, according to the decision method of the performed forge or true or paper money of the bank note information that reads by above-mentioned bank note reading device 20.

The authenticating method of the bank note of present embodiment has following steps: first comparison step, the illumination of predetermined wavelength is mapped to the printing zone of genuine note note surface from light-emitting device, also store in advance as reference data with the optical transmission light data that seen through this genuine note bank note, from light-emitting device the illumination of above-mentioned predetermined wavelength is mapped to the printing zone that becomes the note surface of judging object then, the optical transmission light data and the said reference data that will see through this bank note compare; With second comparison step, in the printing zone of note surface, pre-determine the specific region, the weighting that above-mentioned optical transmission light data in the above-mentioned specific region of the bank note that becomes above-mentioned judgement object and above-mentioned genuine note bank note are scheduled to, data after this weighting are compared mutually, comparative result according in these first, second comparison step carries out the judgement of forge or true or paper money.

Promptly, in the printing zone of note surface, for example, the zone that the image that will obtain under visible light and under the infrared light has nothing in common with each other pre-determines and is the specific region, compares with the transmitted light data that obtain from other zone, and the transmitted light data of the infrared light in this specific region are implemented weighting, data after these weightings are compared mutually, thus, and with relatively the comparing mutually of the transmitted light data in the whole printing zone of note surface, further improved the precision of identification.

Like this, have on the genuine note bank note under the visible light and the zone that the image that obtains has nothing in common with each other under the infrared light, for example in the watermark region on being arranged at bank note, under the situation of observing this regional image with the light of different wave length (for example observe the situation of this regional image and under the situation of observing under the infrared light) with red light, observe image a great difference is arranged, be conceived to this point, should the zone as the specific region, obtain the transmitted light data that infrared light obtains of passing through in this specific region, to these transmitted light data that obtain, and the transmitted light data in same specific region of the genuine note of obtaining in advance are weighted respectively, data after the weighting are compared mutually, thereby to becoming the bank note of judging object is genuine note or counterfeit money, carries out identification with higher precision.At this moment, determine the specific region, and, also can further improve the precision of identification thus the weighting that the transmitted light data setting in this specific region is scheduled to according to face amount.

In any one of first comparison step and second comparison step, compare when carrying out identification in the data that will obtain and reference data, because the transmitted light data can be concentration value (brightness value) expression with gray-scale value, therefore, can utilize by the related coefficient that calculates in the relational expression that its substitution is suitable and judge.

In addition, generate for example analog waveform, compare mutually, also can judge by shape to this waveform according to the transmitted light data.

In addition, in the time will becoming the bank note of judging object and genuine note bank note and compare, except using optical transmission light data, can also use light in the above-mentioned specific region reflected light data.For example except the transmitted light data of above-mentioned infrared light, can also use the reflected light data of the infrared light in above-mentioned each specific region.

That is,, can further improve the judgement precision by on the basis of comparing the transmitted light data, also comparing reflected light data.Consider in addition in the printing zone of note surface, to exist reflected light data than the easy zone relatively of transmitted light data, under these circumstances, also can be only by to reflected light data weighting judge.

In addition, above-mentioned light-emitting device can shine the light of different wave length, when bank note that relatively becomes the judgement object and genuine note bank note, can also use the optical transmission light data and/or the reflected light data of the different wave length in the above-mentioned specific region.Promptly, for example light-emitting device is constituted and to shine infrared light and red light, in the time will becoming the bank note of judging object and genuine note bank note and compare, the transmitted light data and/or reflected light data of the infrared light in using above-mentioned specific region, can also use the transmitted light data and/or the reflected light data of red light.

Like this, because infrared light is different with red light wavelength, therefore, when the multiple optical transmission light data that wavelength is different and reflected light data are applied to the identification of bank note, such character can also be used in the identification of bank note: from the transmitted light of the specific region by genuine note and counterfeit money with from the reflected light of specific region reflection, transmissivity is different respectively with reflectivity, by adopting this method, can further improve the judgement precision.Also transmitted light data and reflected light data are implemented weighting in the case.And,, also can carry out weighting in various degree respectively, thereby can further improve the identification precision at being subjected to the light data from the transmitted light of the wavelength that differs from one another and each that reflected light obtains.

In addition, as above-mentioned specific region, it comprises the different zone of light time gained data of shining different wave length.For example except considering above-mentioned " watermark " zone etc., also comprise the zone that is printed with latent image and utilize the zone of pearl ink printing.On bank note, there is the different zone of light time gained data of other different wave length of irradiation, more preferably,, improves the identification precision by plural at least zone is set at the specific region.

Above-mentioned latent image is one of anti-counterfeiting technology.For example, as go up implementing at the current bank note of Japan (Bank of Japan's banknote) like that, above-mentioned latent image is to cannot see when direct-view but the image that displays during from oblique observation.On Bank of Japan's banknote, in the zone that under the state of direct-view, does not have whatever, when inclination bank note, can appear literal such as " NIPPON " in one's mind.

In addition, through observation shows that, when photograph in the zone that the infrared transmission that is in the wavelength in the preset range in making near infrared range is printed with such latent image, just can identify the literal of hiding above-mentioned " NIPPON ".And, in the present embodiment, in general and from the cost aspect consider, use near the optical sensor of the cheap light of illumination wavelength 950nm, used near the wavelength the 950nm as the wavelength that is in the preset range, but be not limited in this wavelength as the wavelength that is in the preset range,, just can from a large scale, suitably select to use so long as be included in the wavelength in the near infrared range.

Thus, in the zone that is printed with latent image as the zone that is difficult to forge, when judgement becomes the bank note of judging object and genuine note bank note, under the situation that the transmitted light data of the infrared light that uses near the wavelength the 950nm be in above-mentioned scope respectively compare mutually, think that both difference shows more significantly, to judging that the true and false is extremely effective.By the transmitted light data weighting was compared afterwards, can make the difference of genuine note and counterfeit money become more obvious especially.

In addition, in Bank of Japan's banknote, also adopt above-mentioned pearl ink for false proof, when inclination bank note, the printing position will appear the slightly nacreous lustre of pink colour in one's mind.Because the printing of above-mentioned pearl ink also is difficult to forge, therefore, compare to determine object bank note and genuine note by using the transmitted light data and the reflected light data that behind the sub-region right that utilizes the pearl ink printing, obtain, can be easily and correctly carry out identification.

Promptly, because pearl ink is the printing ink that includes pearlescent pigment, this pearlescent pigment is the pigment that is coated with metal oxides such as titanium dioxide, iron oxide on natural mica, intersection at the medium of low mica of the high titanium oxide layer of refractive index and refractive index and periphery thereof, optical multiple reflector interferes, thereby produce unique nacreous lustre, so produce and to obtain identical catoptrical pearl ink and be not easy, therefore, if be weighted, then can correctly carry out the identification of genuine note and counterfeit money in the zone that utilizes the pearl ink printing.

In addition, though compare with the data that other zone from the printing zone of note surface is obtained, the weighting that the transmitted light data that obtain from the specific region and reflected light data are scheduled to, but, for example consider to multiply by the weight multiple proportions on transmitted light data in above-mentioned specific region and/or the reflected light data as predetermined weighting.

That is, in the above-mentioned relational expression of the transmitted light data judging forge or true or paper money that uses infrared light, on concentration value, multiply by the weight multiple proportions, increase the comparison amplitude of operation values, also can further improve the judgement precision based on obtained data.

Because the value of weight multiple proportions can be carried out various settings, therefore, only, also can tackle various evaluations by the value of change weight multiple proportions after obtaining data.

In addition, as mentioned above, if under the situation that the analog waveform of the concentration (brightness) that the transmitted light data of utilizing expression from above-mentioned specific region and/or reflected light data generate compares, then consider with predetermined multiplying power waveform amplification.In the case, owing to the comparison between the waveform that has become after amplifying, therefore further improved the judgement precision.

In addition, as comparing the method that the above-mentioned transmitted light data that obtain from the specific region and reflected light data are implemented predetermined weighting with the data that obtain from other zone, the data volume of also considering to make transmitted light data in the above-mentioned specific region and/or reflected light data increases (perhaps make the coordinate density in the specific region closeer than other zone) than other regional data volume.

Comparatively speaking, also can make specific region data volume or coordinate density in addition sparse, in the case, also can improve data-handling efficiency.In addition, also can change packing density by each specific region.

Describe particularly, for example as the light-emitting device of infrared light and red light, the a large amount of LED of preferred use is set to the led array of wire etc., but under the situation of using this zone in addition, led array irradiation specific region, select LED and drive, in the specific region, can drive all LED.By such method, can access energy-conservation effect.

And, since the specific region on the note surface zone, can be used as coordinate carry out specific, therefore, can by control above-mentioned bank note transport mechanism 8 conveyance bank note speed, make conveyance speed in the specific region than slow, to increase the data volume of transmitted light data and reflected light data in other zone.

Specifically, paper money identifier is considered following structure.

Promptly, paper money identifier constitutes the bank note reading device, this bank note reading device is to the bank note irradiates light by above-mentioned bank note transport mechanism 8 conveyances, and accept to have seen through the transmitted light of above-mentioned bank note and the reflected light that reflects from above-mentioned bank note after the irradiation, this paper money identifier has: weighting device, its to by light sensors to the light data that are subjected to implement weighting, the specific region that this light sensors is determined in the printing zone of above-mentioned note surface; With identification portion, it judges the true and false of bank note, and above-mentioned identification portion has: memory storage, its storage comprise the benchmark of above-mentioned specific region in whole printing zones of interior genuine note note surface and be subjected to the light data; First comparison means, it is subjected to the light data, compares with the light data that are subjected in the whole printing zones of obtaining by above-mentioned optical sensor that become the note surface of judging object being stored in said reference in the above-mentioned memory storage; With second comparison means, its light data that are subjected to after to the weighting in above-mentioned each specific region of the bank note that becomes above-mentioned judgement object and above-mentioned genuine note bank note compare mutually.

In the case, identification portion can be made of microcomputer, and this microcomputer has CPU and as ROM, the RAM etc. of memory storage.Can in above-mentioned ROM, store following content in advance: decision procedure, it makes this microcomputer carry out above-mentioned authenticating method; Be subjected to the light data in whole printing zones of note surface, what it comprised the specific region that becomes in the genuine note of the reference data bank note is subjected to light data (for example, the transmitted light data and the reflected light data of the transmitted light data of infrared light and reflected light data and red light); Implement the program of weighting with the light data that are subjected to that are used for the specific region.

In addition, obtaining by optical sensor becomes being subjected to the light data and it being stored among the RAM of the bank note of judging object, and relatively this is subjected to light data and reference data to utilize first comparison means and second comparison means, carries out identification thus.And, as first comparison means and second comparison means, needn't be by dividing other hardware constitute, can undertake this function simultaneously by above-mentioned identification portion.

In addition, as light-emitting device, can use aforesaid led array, in the present embodiment, light-emitting device is equipped with first light emitting array that sends infrared light and second light emitting array that sends red light.

In addition, as being subjected to the light data, except using the transmitted light data also to use reflected light data also, perhaps, make the light that shines on the bank note except independent infrared light, also increase red light, thus, in the mutual comparison that respectively is subjected to the light data, even only having under the situation that has broken away from the standard that can be judged to be genuine note, also be judged to be counterfeit money, thereby can significantly improve the judgement precision.

In addition, the reference data of genuine note can be stored in the memory storage in advance, be subjected to light data on one side still for example also can obtain by bank note transport mechanism 8 conveyance genuine notes on one side, and these data are stored as reference data.Therefore, also can be by the corresponding optimized reference data of each authenticity determining device storage.In addition, if methods such as use moving average are upgraded reference data,,, also can make reference data reach optimization even do not carry out white compression etc. at any time then in order to tackle the aging of hardware with being adapted to the output change.

In addition, in the authenticating method of above-mentioned paper money identifier, first comparison step and the differentiation of second comparison step are illustrated, in above-mentioned first comparison step, to see through the transmitted light data of the infrared light of the whole printing zones that become the note surface of judging object, compare with the said reference data; In above-mentioned second comparison step, transmitted light data to the above-mentioned infrared light in the specific region specific in advance in the printing zone of note surface are implemented predetermined weighting, data after this weighting are compared becoming between the bank note of judging object and the above-mentioned genuine note, but also can compare simultaneously and first comparison step and second comparison step are not distinguished.

For example, use and organized the identification program of relatively using relational expression that comprises the relational expression that is used for weighting in advance, in the reflected light data of the red light of the transmitted light data of the infrared light of the whole printing zones that seen through the genuine note note surface and reflection, will in the specific region, the data after the weighting in advance be kept in the memory storage as reference data.

On the other hand, reflected light data from the red light of the transmitted light data of the infrared light that seen through the whole printing zones that become the note surface of judging object or reflection, weighting to above-mentioned specific region part is also carried out concurrently, compares with the said reference data then.At this moment, data also can generate represents for example waveform of brightness value (concentration value), compares by this waveform then.

Promptly, a kind of authenticating method of bank note, from the infrared light of light-emitting device to the printing zone irradiation predetermined wavelength of the genuine note bank note that pre-determined the specific region, in the transmitted light data of the infrared light that has seen through this genuine note bank note, the transmitted light data that seen through above-mentioned specific region are scheduled to weighting, data after this weighting are stored in advance as reference data, on the other hand, the printing zone that becomes the note surface of judging object is shone the infrared light of above-mentioned predetermined wavelength from light-emitting device, in the transmitted light data of the infrared light that has seen through this bank note, the transmitted light data that seen through above-mentioned specific region are implemented the weighting identical with above-mentioned genuine note, and will comprise transmitted light data in the above-mentioned specific region after this weighting in all interior transmitted light data, compare with the said reference data, judge the true and false thus.

Also can carry out identification by said method with high precision.Be used to realize that the paper money identifier of this method has: optical sensor, it light shines on the bank note by 8 conveyances of bank note transport mechanism, and to irradiation and seen through the transmitted light of above-mentioned bank note and be subjected to light from the reflected light of above-mentioned bank note reflection; Weighting device, its in the specific region of in the printing zone of above-mentioned note surface, determining, by above-mentioned light sensors to the light data that are subjected to implement weighting; With identification portion, it carries out above-mentioned authenticating method, and this identification portion can constitute to have: memory storage, its storage comprise the reference data of above-mentioned specific region in whole printing zones of interior note surface; And comparison means, the light data that are subjected in its whole printing zones that become the note surface of judging object that can obtain with the reference data in the above-mentioned whole printing zones that are stored in the above-mentioned memory storage with by above-mentioned optical sensor compare, and the light data that are subjected to that become after the weighting bank note of above-mentioned judgement object and above-mentioned genuine note bank note, in above-mentioned each specific region can be compared mutually.

With reference to Figure 11 to Figure 14,, carry out more specific description to the structure of the paper money identifier of the authenticating method of carrying out aforesaid bank note.

In these figure, Figure 11 is the synoptic diagram of presentation graphs 1 to the structure of bank note treatment device shown in Figure 4, Figure 12 is the block scheme of the control system of expression bank note treatment device, Figure 13 is the key diagram that is stored in the reference data table in the reference data storage part, in addition, Figure 14 is the surface of expression bank note and the schematic illustration at the back side.

Above-mentioned bank note reading device 20 has: luminescence unit 24, and it is provided in upper frame 2A side, and have can be to by first illuminating part 23 of the upside of the bank note of conveyance irradiation infrared light and red light; Be subjected to luminescence unit 25, it is configured in lower frame 2B side.This is had by luminescence unit 25: light accepting part 26, and it has across bank note and first illuminating part, the 23 opposed optical sensors that are subjected to; With second illuminating part 27, the bank note conveyance direction both sides of itself and light accepting part 26 are adjacent to configuration, can shine infrared light and red light.

Play a role with light source as transmission with first illuminating part 23 of above-mentioned light accepting part 26 arranged opposite.As shown in Figure 2, this first illuminating part 23 is made of plastic rectangular rod body, and this rectangular rod body makes from the light of the LED element 23a that is installed in the one end light conductor 23b by the portion of setting within it and sends.First illuminating part of Gou Chenging and light accepting part 26 (being subjected to optical sensor) set abreast and are wire like this, thereby can be with simple structure, and to the scope of the whole Width in the conveyance path of the bank note of institute's conveyance, integral body is shone equably.In addition, such first illuminating part 23 and light accepting part 26 (being subjected to optical sensor) play a role as the attachment recognition device, and this attachment recognition device is used for whether the outside in bank note physical dimension is connected with attachment and discerns.Promptly, if on bank note, be connected with for example attachment such as rope or line, and this attachment inserts oral-lateral to bank note and extends, and then just can detect its light quantity and change in light accepting part 26, thereby can detect the connection of attachment at the whole Width in bank note conveyance path.

The above-mentioned light accepting part 26 of luminescence unit 25 that is subjected to forms the tabular of thin thickness, and it extends along the direction of intersecting with bank note conveyance path 5, and to form width be the band shape that does not influence the degree of the not shown sensitivity that is subjected to optical sensor that is arranged at light accepting part 26.And, the above-mentioned optical sensor that is subjected to constitutes as so-called line sensor, its central authorities at the thickness direction of light accepting part 26 are provided with a plurality of CCD (Charge Coupled Device: charge-coupled image sensor) with being wire, and dispose selfoc lens array 26a in the top position of this CCD, so that transmitted light and reflected light are assembled with being wire.Therefore, above-mentioned be subjected to optical sensor accept towards the bank note irradiation that becomes the identification object, from the infrared light of first illuminating part 23 and second illuminating part 27 and the reflected light or the transmitted light of red light, and with them as being subjected to the light data, thereby can generate the gradation data corresponding, or generate two dimensional image according to this gradation data with its brightness.

In addition, played a role with light source as reflection by second illuminating part 27 of luminescence unit 25.This second illuminating part 27 is identical with first illuminating part 23, as shown in Figure 3, it is made of plastic rectangular rod body, this rectangular rod body is equipped with LED element 27a at one end, it can make from the light of this LED element 27a by being arranged on inner light conductor 27b uniform irradiation integrally.This second illuminating part 27 also constitutes to set abreast with light accepting part 26 (being subjected to optical sensor) and is wire.

Above-mentioned second illuminating part 27 set into, can be with the elevations angle of 45 degree towards the bank note irradiates light, and accept reflected light from bank note by light accepting part 26 (being subjected to optical sensor).In the case, incide light accepting part 26 (being subjected to optical sensor) from the light of second illuminating part 27 irradiation with 45 degree, but incident angle is not limited in 45 degree, as long as just can suitably set in the catoptrical scope can accepting reliably.Therefore, about the configuration of second illuminating part 27 and light accepting part 26,, can suitably carry out design alteration according to the structure of bank note treatment device.In addition, above-mentioned second illuminating part 27 clips light accepting part 26 and is arranged on both sides, and from both sides respectively with 45 the degree the incident angle irradiates lights.This exists under the situation of scar or gauffer etc. in note surface, if light only from one-sided irradiation to the concavo-convex situation that partly produces at these scars or gauffer, will inevitably produce in concavo-convex part sometimes that light is covered and the position that becomes shade.Therefore,, can prevent from shade to occur, can obtain precision and be higher than from the view data of the situation of one-sided irradiation at jog by from the both sides irradiates light.Certainly, second illuminating part 27 also can be only to be arranged on one-sided structure.

Because the above-mentioned luminescence unit 25 that is subjected to is exposed on the bank note conveyance path 5, therefore as shown in Figure 2, be formed with jog 25a at the two ends of the bank note conveyance direction of its surface portion (with the conveyance face 5a part of coplane roughly), so just be difficult for tangling the bank note of institute's conveyance.In addition, luminescence unit 24 also be subjected to luminescence unit 25 identical, also as shown in Figure 2, be formed with jog 24a at the two ends of the bank note conveyance direction of its surface portion, just be difficult for tangling the bank note of institute's conveyance thus.

And above-mentioned luminescence unit 24 is not limited in present embodiment with structure that is subjected to luminescence unit 25 and configuration etc., can carry out suitable distortion.

In above-mentioned ROM112, store the various programs and the permanent data such as operation program, identification program of various drive units such as above-mentioned driving motor 10, electromagnet 54 and LED70, CPU110 is according to the said procedure action that is stored among the ROM112, and by carrying out the input and output of signal between I/O port one 20 and the above-mentioned various drive unit, thereby carry out the action control of paper money recognition treating apparatus.That is, driving motor driving circuit 125 (driving motor 10), electromagnet 54 and LED70 are connected with CPU110 by I/O port one 20.These drive units are according to the operation program that is stored among the ROM112, according to the control signal control action from CPU110.In addition, import among the CPU110 by I/O port one 20 by the detection signal of detecting sensor 60 from the detection signal of banknote detection sensor 18 and from bank note, according to these detection signals, carry out the drive controlling of extinguishing control and electromagnet 54 of lighting of just the changeing of driving motor 10/inversion driving control, LED70.

In above-mentioned RAM114, store data and the program when CPU110 moves, used, in reference data storage part 116, the reference data of using in the time of will carrying out the forge or true or paper money judgement, be about to the gradation data obtained from whole printing zones of genuine note bank note, press transmitted light, the reflected light of transmitted light, reflected light and the red light of infrared light respectively, be stored as benchmark and be subjected to the light data.And, in the present embodiment, reference data is stored in the special-purpose reference data storage part 116, but also it can be stored among the ROM112.

CPU110 by first illuminating part 23 in I/O port one 20 and the above-mentioned luminescence unit 24, be connected by the light accepting part 26 and second illuminating part 27 in the luminescence unit 25, they constitute forge or true or paper money detection unit 150 with CPU110, ROM112, RAM114, reference data storage part 116, carry out the necessary action control of identification in the bank note treatment device 1.

In addition, CPU110 leases the control part of device by I/O port one 20 and the game medium that is assembled with bank note treatment device 1 or the epigyny devices such as main frame 200 of external device (ED) are connected, and sends various signals (about the information of bank note and caution signal etc.) to epigyny device.

As shown in figure 13, in the presumptive area of the reference data storage part 116 in above-mentioned forge or true or paper money detection unit 150, store four kinds of reference data storage lists, it comprises: the reference data (c) of the catoptrical reference data (b) of the reference data of the transmitted light of infrared light (a), infrared light, the transmitted light of red light and the catoptrical reference data (d) of red light.

More specifically describe, in the reference data storage list, catoptrical gradation data based on red light, gradation data based on transmitted light, and based on the catoptrical gradation data of infrared light, gradation data based on transmitted light, respectively according to seven kinds of face amounts (1,000 yen of new note, 5,000 yen, 10,000 yen, 1,000 yen of old bank note, 2,000 yen, 5,000 yen, 10,000 yen totally seven kinds), and note surface situation and back side situation up up, and, 7 * 2 * 1=14 kind gradation data is stored in the reference data storage list towards the situation that a certain side in the left and right sides (being made as in the present embodiment to the right) of the length direction of bank note inserts.In addition, when identification, judge the direction of insertion of bank note, if direction of insertion is towards a left side, then the reference data of being stored is used in counter-rotating.Certainly, also can shown in Figure 13 (left), will be stored in the reference data storage list towards the reference data of left when inserting of bank note length direction.In the case, just there is 7 * 2 * 2=28 kind gradation data to be stored in the reference data storage list.And, also can will store after the gradation data two dimensional imageization.

And, in the present embodiment, pre-determine in the printing zone in note surface as the red light of the visible light specific region different with visibility under the infrared light, the data that will obtain from this specific region as the special datum data storage reference data storage part 116.

Herein, above-mentioned specific region is described.As shown in figure 14, be on the Japanese bank banknote at the bank note of Japan, implemented various technology as anti-counterfeiting technology.For example shown in Figure 14 (a), on the surface of bank note M, be formed with lower area: watermark region 40a, it has increased and decreased fiber thickness; Latent image zone 40b, it be can't see under the situation of direct-view, but will display during from oblique observation; Special printing zone 40c, it utilizes the pearl ink printing, and when inclination bank note, the slightly nacreous lustre of pink colour is appeared at the printing position in one's mind; And infrared transmission zone 40d, infrared light is seen through for it but red light etc. can not see through, and in addition, shown in Figure 14 (b), also is formed with above-mentioned watermark region 40a and latent image zone 40b at the back side of bank note.

Above-mentioned watermark region 40a, latent image zone 40b, special printing zone 40c and infrared transmission zone 40d are the zones that is difficult to forgery, in genuine note and counterfeit money, produce following characteristic: in watermark region 40a, latent image zone 40b, special printing zone 40c, the brightness meeting of the reflected light of infrared light, red light and transmitted light produces very big different, so the impervious characteristic of red light in the 40d of infrared transmission zone is very useful to the identification of bank note.In the present embodiment, these zones are set at the specific region, by the position of each specific region on the coordinate convention bank note.Particularly in the 40b of latent image zone, be difficult to identify latent image by transmitted light, but in the present embodiment, be near the infrared light the 950nm, just can identify image, so can be used as the key element of identification effectively by using wavelength.

And, in old bank note, owing to do not have latent image zone 40b and special printing zone 40c, so the watermark region 40a that uses new and old bank note to have at least carries out identification.

In addition, find in the present embodiment, when making wavelength is that (wavelength is the near infrared ray of 920nm～980nm near the 950nm infrared light, preferably be in the near infrared ray in 940nm～960nm scope) when photographing through latent image zone 40b, can identify hiding image, therefore in new note, this latent image zone 40b also is used in the identification as the specific region.Therefore, the infrared light wavelength from first illuminating part 23 and 27 irradiations of second illuminating part is 950nm.

Like this, store reference data and special datum data in advance in the reference data storage part 116 of the bank note treatment device 1 of present embodiment, these special datum data are made of the gradation data of extracting out at above-mentioned specific region from this reference data.And, about the special datum data, with the catoptrical special datum data of the special datum data of the transmitted light of the catoptrical special datum data of the special datum data of the transmitted light of infrared light, infrared light, red light and red light formization respectively, and be stored in the presumptive area of reference data storage part 116.

In bank note treatment device 1 with said structure, in the present embodiment, its unique point is, at genuine note bank note and become between the bank note of judging object, except the gradation data that compares bank note integral body, also the gradation data that obtained by light data (transmitted light data and reflected light data) from above-mentioned specific region is weighted, and the gradation data after this weighting is compared mutually, can carry out identification accurately thus.

Promptly, to the special datum data (gradation data that generates from the transmitted light data of the red light that seen through the specific region and infrared light, the gradation data that generates with reflected light data) from red light after specific region reflection and infrared light, implement weighting described later respectively, when the identification of bank note, to compare from gradation data and the said reference data whole printing zones that the bank note that becomes the judgement object is obtained, and the gradation data from the gradation data taking-up specific region that becomes the bank note of judging object, it is implemented and the same weighting of special datum data, and further between specific gradation data after the weighting and above-mentioned special datum data, compare.

Promptly, in the bank note treatment device 1 of present embodiment, when becoming the bank note during of judging object from bank note conveyance mouth input and conveyance, from above-mentioned first illuminating part 23 and second illuminating part 27, will with the identical infrared light and the red light of optical wavelength of irradiation genuine note bank note, shine the printing zone of note surface, will be from infrared light and the transmitted light data of red light and the four kinds of gradation datas that reflected light data obtains that seen through this bank note, in RAM114, launch respectively, with these data and four kinds of (transmitted light of infrared light and reflected light being stored in the reference data storage part 116, the transmitted light of red light and reflected light) reference data compare mutually, and the specific gradation data that each the transmitted light data and the reflected light data of infrared light from above-mentioned specific region and red light obtained, implement and the same weighting of above-mentioned genuine note bank note, four kinds of specific gradation data after this weighting are launched in RAM114, respectively these data and four kinds of special datum data are compared correspondingly successively, though comparative result have one for NG (can not) also be judged to be counterfeit money.

Herein, in the identification portion 150 of above-mentioned bank note,, the actual treatment step that carries out the forge or true or paper money judgement is described with reference to Figure 15～Figure 18.

Figure 15 is the main flow chart of expression bank note determination processing step, Figure 16 is that expression is shone infrared light and red light and accepted transmitted light and bank note figure sweep time of catoptrical timing on bank note, Figure 17 is the face amount of expression judgement face amount and bank note conveyance direction, the process flow diagram that direction determining is handled, in addition, Figure 18 is the process flow diagram of the step of expression identification processing.

And, processing in each process flow diagram is carried out by the identification program that is stored among the ROM112, this identification program constitutes and makes CPU110 carry out following steps: from first illuminating part 23 and second illuminating part 27 as light-emitting device, the infrared light of above-mentioned predetermined wavelength is shone the step on the printing zone on the surface that becomes the bank note of judging object; First comparison step that the reference data of the transmitted light data of the infrared light that seen through this bank note and storage is in advance compared; The transmitted light data of the infrared light in each specific region of the bank note that becomes above-mentioned judgement object and above-mentioned genuine note bank note are implemented the step of predetermined weighting; Second comparison step that data after this weighting are compared mutually; And, carry out the step of the identification of bank note according to the comparative result in first, second comparison step.

Begin most, the CPU110 of bank note treatment device 1 judges whether detect bank note (step S01).Whether this detects the insertion of bank note by banknote detection sensor 18 and sends detection signal and judge, when banknote detection sensor 18 detects bank note, carries out the identification of bank note and handles.

Then, CPU110 outputs to first illuminating part 23 and second illuminating part 27 with project signal, from red light and the infrared light of each illuminating part 23,27 output as visible rays, and shine towards bank note, carry out note surface whole printing zone gradation data read processing, and generate two dimensional image (step S02).

At this moment, because first illuminating part 23 and second illuminating part 27 are configured to the wire of extending along the direction of intersecting with respect to bank note conveyance path 5, so be mapped on the whole width of bank note from the illumination of first illuminating part 23 and 27 outputs of second illuminating part.In addition, red light of being shone and infrared light are from whole the transmission or the reflection of bank note, and these transmitted lights and reflected light are input to being subjected in the optical sensor of light accepting part 26.As mentioned above, also be line sensor owing to be subjected to optical sensor, thus can on its whole length, detect the reflected light and the transmitted light of each light, and read gradation data.

In addition, gradation data in present embodiment reads in the processing, as shown in figure 16, by each red light of first illuminating part 23 and second illuminating part 27 and infrared light four light sources that to be red light and infrared optical transmission constitute with light source with light source and red light and infrared reflection of light, with constant appropriate intervals, light repeatedly and extinguish, and the phase place of each light source can be not overlapping, plural light source not can with the time light.In other words, when the bright lamp of certain light source, other three light sources all extinguish.

Therefore, as present embodiment, even a light accepting part 26 also can detect the light of each light source by constant interval, and read the image that constitutes by gradation data based on the printing zone of the transmitted light of the transmitted light of red light and reflected light, infrared light and catoptrical, bank note.

Whether there is attachment to be connected detection (step S03) on the bank note then.This in step S03, finish gradation data read processing after, then carry out (being set in the present embodiment of bank note to storage position, bank note by conveyance to the bank note rear end from the position of line sensor downstream side near the position about 13mm) conveyance handle, in this is handled, in light accepting part 26 as line sensor, by detect attachments such as whether rope or line are arranged be connected bank note after bring in and carry out.As mentioned above, because line sensor detects the whole width in bank note carrying channel footpath, promptly detect the whole width of bank note, therefore, no matter which position attachment is connected, and it can both be detected.After the rear end of bank note is passed through,, then carry out bank note and judge that NG handles (step 803 if detect attachment; Yes, step S10).And, among this step S03 to whether connecting the identification processing execution of appendiculate detection prior to the bank note among the step S07 described later, pay the utmost attention to the recognition result of attachment and control.

Next, CPU110 carries out face amount, direction determining to be handled, judge the face amount (for example 1,000 of new note yen, 5,000 yen, 10,000 yen, old bank note 1,000 yen, 2,000 yen, 5,000 yen, 10,000 yen totally 7 kinds) of the bank note that is inserted and direction of insertion (according to note surface be go up or down and this moment, bank note inserted is four direction towards difference) (step S04).And, handle about this face amount, direction determining, will be described in detail in the back.

Then, CPU110 judges whether to judge face amount and conveyance direction (step S05), and is for example serious stained or damaged and under the situation about can not judge (NO of step S05), processing is moved to step S10 at bank note, carries out bank note and judges that NG handles.In this bank note judges that NG handles, CPU110 will make the signal of driving motor 10 reverse rotations output to driving motor driving circuit 125, make bank note turn back to bank note forcibly and will insert mouth 6, and move to step S01 once more.

On the other hand, under the situation that can judge face amount and direction (Yes of step S05), make the two dimensional image of obtaining within the specific limits move forward into line position compensation, so that the related coefficient maximum (step S06) of itself and reference data.

In addition, in step S07, carry out the identification of bank note.To be described in detail in the back this identification, and only carry out simple declaration here, at first, calculating obtains related coefficient and difference absolute value between data and the reference data to four kinds of light sources (infrared transmission, infrared external reflection, red transmission and red reflex) respectively.Extract the specific region then and be weighted, to the related coefficient after four kinds of light sources calculating weightings.And then, for transmission data, only extract watermark region 40a, get differential coefficient in inside and calculate its size.At last, computing related coefficient between the special datum data in watermark region 40a.In addition, if all related coefficients of calculating all in the scope of determining, just are judged to be genuine note,, also be judged to be counterfeit money even only have one outside scope.

At this moment, also consider to use a large amount of genuine note bank note,, use the identification of horse formula distance (Mahalanobisdistance) by mean value, variance and the covariance of obtaining each numerical value in advance as sample.This is not individually to consider the numerical value of calculating, and is to use multivariable analysis synthetically to judge.

And the required time of identification is about 0.7s, and bank note is about 0.1s by conveyance to time of storage position, and carrying out the time that forge or true or paper money judges in storage position is about 0.6s.In addition because before the identification of this bank note was handled, whether identification was connected with above-mentioned attachment (step S03), therefore, behind identification, even with the bank note conveyance in the process of storage position, also can prevent devious conduct reliably.

In addition, be to be judged to be under the situation of genuine note (Yes of step S08) in the identification result, carry out and judge that OK handles (step S09).This processing is carried out after bank note becomes the keeping state, for example is equivalent to various processing such as exchange, prepaid card sale, writing recording medium.

In the processing of above-mentioned steps S08, be judged as at bank note under the situation of counterfeit money, in addition, in the processing of above-mentioned steps S03, be judged to be under the appendiculate situation of connection, carry out bank note and judge that NG handles (step S10), during bank note in this case judges that NG handles, also can carry out and different processing when step S05 shifts before.

For example, be judged as at bank note under the situation of counterfeit money, perhaps, also can not return the bank note that is inserted, hold state and still rest on being judged to be under the appendiculate situation of connection, and to epigyny device 200 output alarm signals.Perhaps, under situation as described above, also can return bank note, but recur at same state under three times the situation, to epigyny device 200 output alarm signals initial twice.Thus, even genuine note but owing to adhere to or be connected with unnecessary attachment, and be not judged as under the situation of genuine note, sometimes just can be judged to be genuine note by remove attachment by the user, saved the trouble of carrying out useless maintenance, also can prevent to bring uncomfortable feeling to the user.

Next, face amount, the direction determining that describes above-mentioned steps S04 in detail handled.And, as previously mentioned, in the reference data storage part 116 of forge or true or paper money detection unit 150, store according to four kinds of light (transmitted light of the transmitted light of infrared light and reflected light, red light and reflected light) each, the reference data to right of seven kinds of face amounts.

As shown in figure 17, CPU110 at first for example selects the transmitted light section data of infrared light from the two dimensional image that is generated by gradation data, above-mentioned gradation data promptly obtains (step S11) from whole printing zones from by whole of the bank note that becomes the identification object of conveyance.

Next, check the similar degree of obtaining data and reference data (step S12) of 28 kinds (direction of insertion at bank note is the data reversal that makes towards the right side) of seven kinds of face amounts, four direction under the situation on a left side.Specifically, as the index of expression similar degree, use the coefficient R that is expressed from the next.

[formula 1]

$R=\frac{\underset{i}{\mathrm{\Σ}}\underset{j}{\mathrm{\Σ}}\left(f\right[i,j]-F)\left(s\right[i,j]-S)}{\sqrt{\underset{i}{\mathrm{\Σ}}\underset{j}{\mathrm{\Σ}}{\left(f\right[i,j]-F)}^2}\sqrt{\underset{i}{\mathrm{\Σ}}\underset{j}{\mathrm{\Σ}}{\left(s\right[i,j]-S)}^2}}$

And, in formula, [i, j] is the coordinate of bank note, at this bank note coordinate [i, j] in, be made as f[i, j from the concentration value (brightness value) of the two dimensional image of obtaining data that becomes the bank note of judging object], concentration value in the reference data is made as s[i, j], the mean concentration that obtains data is made as F, and the mean concentration of reference data is made as S.

Coefficient R is got-1～+ 1 value, and approaching+1 is judged to be the similar degree height.In addition, calculating the related coefficient between the reference data of each four direction of all and seven kinds of face amounts, is the face amount, the direction of being inserted that become the bank note M that judges object with the face amount and the direction determining of expression mxm..

And, in the present embodiment, owing in advance the gradation data in whole printing zones of note surface is stored as reference data, so employing said method, but also can be not according to this method, so long as the degree of identification face amount, direction also can not carried out the identification in whole printing zones.For example, also can be on three lines (central authorities of bank note M, about 9mm, the following about 9mm of distance) of long side direction apart from the top, calculating obtains the related coefficient of data and reference data, and the data judging that the mean value of three lines is the highest is face amount, the direction that becomes the bank note M of identification object.In the case, because judgement becomes simple, therefore also can shorten the judgement time.

Next, CPU110 carries out the judgement (step S13) in the processing of step S12, if having the face amount that is fit to according to result of determination, for the identification of back is handled, be provided with and determine the face amount that is fit to, the identification code (step S14) of direction, handle moving to step S04.On the other hand,, the identification code (step S15) that is fit to bank note is set, handles moving to step S04 in that judgement does not exist under the situation of suitable face amount according to result of determination.

Next, the identification processing to the step S06 among Figure 15 is elaborated.

As shown in figure 18, CPU110 is respectively to each of four kinds of light (transmitted light of the transmitted light of infrared light and reflected light, red light and reflected light), becoming between the reference data of gradation data that the bank note M that judges object obtains and storage in advance the similar degree (step S21) of calculating in whole printing zones of note surface.At this moment, the difference absolute value sum SUM that uses coefficient R and be expressed from the next.

[formula 2]

$\mathrm{SUM}=\underset{i}{\mathrm{\Σ}}\underset{j}{\mathrm{\Σ}}\left|f\right[i,j]-s[i,j\left]\right|$

And in formula, [i, j] is the coordinate of bank note, in this bank note coordinate [i, j], is made as f[i, j from the concentration value (brightness value) of the two dimensional image of obtaining data that becomes the bank note of judging object], the concentration value in the reference data is made as s[i, j].

Next, judge whether coefficient R and difference absolute value sum SUM are in the permissible range (step S22).At this moment, the value of coefficient R is approaching more+and 1, difference absolute value sum SUM obtains data just more near reference data more near 0 in addition.In addition,, the sign indicating number (step S30) of " being counterfeit money " is set, handles moving to step S07 if outside permissible range (No of step S22), then be judged to be counterfeit money.On the other hand, in step S22,, then handle moving to step S23 if the value of coefficient R is in the permissible range (Yes of step S22).

In step S23, between data of extracting from the specific region and special datum data, give big weight, calculate coefficient R W+.And the specific region of She Dinging is latent image zone 40b and special printing zone 40c herein, and these zones are in red light and the different zone of gray scale under the infrared light, have negative correlation between red light and the infrared light.In addition, in the present embodiment, the weight mapping graph that preparation is calculated in advance, and the coefficient R W+ of the weighting shown in being calculated as follows.

[formula 3]

$\mathrm{Rwi}=\frac{\underset{i}{\mathrm{\Σ}}\underset{j}{\mathrm{\Σ}}W[i,j]\left(f\right[i,j]-F)\left(s\right[i,j]-S)}{\sqrt{\underset{i}{\mathrm{\Σ}}\underset{j}{\mathrm{\Σ}}W[i,j]{\left(f\right[i,j]-F)}^2}\sqrt{\underset{i}{\mathrm{\Σ}}\underset{j}{\mathrm{\Σ}}W[i,j]{\left(s\right[i,j]-S)}^2}}$

At this moment, for the transmitted light of red light and infrared light, the weight mapping graph that utilizes transmitted light to use calculates weighted correlation coefficient, and in addition, for reflected light, the weight mapping graph that utilizes reflected light to use calculates weighted correlation coefficient.

In addition, the weight w[i on each coordinate of regulation specific region, j] can be from the special datum data of red light and infrared light, determine by the formula of representing below, also can when carrying out identification, calculate this weight w[i, j at every turn] determine.

[formula 4]

If (s _r[i, j]-Sr) (s _Ir[i, j]-S _IrThe coordinate of)＜0, then

W[i，j]＝1+c×|(s _r[i，j]-S _r)(s _ir[i，j]-S _ir)|

If (s _r[i, j]-Sr) (s _Ir[i, j]-S _IrThe coordinate of) 〉=0, then

W[i，j]＝1

And, in formula, [i, j] is the coordinate of bank note, at this bank note coordinate [i, j] in, the concentration value of special datum data that becomes the red light of the bank note of judging object is made as sf[i, j], concentration value in the special datum data of infrared light is made as Sir[i, j], the mean concentration of the special datum data of red light is made as Sr, and the mean concentration of the special datum data of infrared light is made as Sir.In addition, c is a weight multiplying power coefficient, is the value of suitably determining.

In addition, judge whether coefficient R W+ is in the permissible range (step S24).Owing to the value of in weighted correlation coefficient RW+, also getting-1～+ 1, so approaching more+1 is judged to be more near the special datum data.In addition, if outside permissible range (No of step S24), just be judged to be counterfeit money, it is the sign indicating number (step S30) of counterfeit money that result of determination is set, and handles to move to step S07.On the other hand, in step S24,, then handle and move to step S25 if be judged to be in permissible range (Yes of step S24).

In step S25, the extracting data watermark region 40a of CPU110 from obtaining by the bank note that becomes the judgement object, and calculate its concentration value.That is, in advance at every kind of face amount, preparing watermark region 40a is white, other masks for deceiving, and by two dimensional image and the mask contrast that will obtain, only extracts watermark region 40a.

In addition,, calculate the big or small g[i of the gradient (gradient) that is expressed from the next, j in order to investigate in the inside of watermark region 40a whether have image], and calculate its summation in whole watermark region 40a.

[formula 5]

$g[i,j]=\sqrt{{\left(f\right[i+1,j]-f[i-1,j\left]\right)}^2+{\left(f\right[i,j+1]-f[i,j-1\left]\right)}^2}$

And, the concentration value of the two dimensional image obtained on the coordinate [i, j] is made as f[i, j].For example, in counterfeit money, there is not watermark part (comprising the more smooth situation of concentration ratio among the watermark region 40a) sometimes by forgeries such as duplicating, in this case, its concentration value step-down.

In addition, CPU110 judges whether the concentration of watermark region 40a is in the permissible range (step S26), if outside permissible range (No of step S26), then be judged to be counterfeit money, and the sign indicating number that result of determination is a counterfeit money (step S30) is set, and handles moving to step S07.On the other hand, in step S26,, then handle and move to step S27 if be judged to be in permissible range (Yes of step S26).

Then, CPU110 calculates coefficient R (step S27), the similarity between the two dimensional image of the watermark region 40a that obtains with observation post and the two dimensional image that generates from reference data.

Then, CPU110 judges whether coefficient R is in the permissible range (step S28), if outside permissible range (No of step S28), then be judged to be counterfeit money, and the sign indicating number that result of determination is a counterfeit money (step S30) is set, and handles moving to step S07.On the other hand, in step S28,, then handle and move to step S29, and the sign indicating number that result of determination is a genuine note (step S29) is set, handle moving to step S07 if be judged to be in permissible range (Yes of step S28).

In addition, in foregoing, in judgement to watermark region 40a, preferably, and as pre-treatment, luminance compensation and the position compensation shown in enforcement is following.

In watermark region 40a, exist longitudinally mostly or horizontal folding line, owing to also longitudinally go up the inequality that produces brightness sometimes, so in comprising the little rectangular area of watermark region 40a, two dimensional image of obtaining and the benchmark image of storing are in advance implemented luminance compensation together, so that longitudinal and transverse gray scale cumulative distribution equalization.And, in the comparison in whole printing zones of bank note,, therefore also they can be ignored because the influence of folding line or inequality is very not big.

In addition, on the position of the image in watermark region 40a (for example personage), all there is individual difference in every bank note, in order to compensate, in preset range, to carry out position compensation by the neighborhood inquiry, and obtains the position of related coefficient maximum in advance.

Like this, there are a plurality of determination steps that use the numerical value of calculating in the present embodiment, and, the judgement that the specific region is weighted also by and the process of usefulness in, only when all entering in the permissible range, all numerical value just is judged to be genuine note, even calculate an extraneous numerical value, also be judged to be counterfeit money.Therefore, the precision of identification is high, also can tackle the pseudo-technology for making of height, needn't constantly develop at new pseudo-technology for making, thereby become the authenticating method of bank note of ratio of performance to price excellence and the authenticity determining device of bank note.

Next, in above-mentioned bank note treatment device 1,, illustrate bank note is carried out the driving motor 10 of conveyance processing and the drive controlling step of electromagnet 54 with reference to the process flow diagram of Figure 19.

Begin most, when banknote detection sensor 18 detects the insertion of bank note and becomes the ON state (Yes of step S51), driving motor 10 is just changeed driving, and LED70 lights (step S52).Thus, the conveyance roller is driven in rotation in the bank note direction of insertion 12,13,14, in bank note conveyance auto levelizer, and notifies user's bank note to handle, to prevent to append insertion bank note.

By conveyance bank note in device, when bank note during by bank note reading device 20 regional, according to above-mentioned Figure 15 to step shown in Figure 180, execution bank note determination processing.In addition, in the stage of carrying out this bank note determination processing, promptly carry out the sealing processing (step S53) of baffle mechanism 50 concurrently with the bank note determination processing.

In the present embodiment, when the banknote detection sensor 18 in the downstream of the rotatable lamella 52 that is arranged on baffle mechanism 50 detects the rear end of bank note (banknote detection sensor 18 is OFF), electromagnet 54 energisings, thus, rotatable lamella 52 is driven rotation by tilting member 57, sector gear 57G, gear 55G and axle 55, as shown in Figure 9, thus rotatable lamella 52 inserts mouthfuls 6 from the outstanding sealing of conveyance face 5a bank note.

Then, in the bank note determination processing of step S53, judge whether exist bank note to judge that NG handles (step S54).When existing bank note to judge that NG handles, carry out the inversion driving of driving motor 10 in this stage and handle, make bank note insert oral-lateral and return (step S55) towards bank note.At this moment, handle owing to carried out the sealing of baffle mechanism 50, institute draws in rotatable lamella 52 so that the driving of electromagnet 54 is OFF (removing energising) from bank note conveyance path 5, thereby can be along discharge direction conveyance bank note (step S56).

In addition, under the state that bank note insertion oral-lateral is return, when driving motor predetermined amounts inversion driving, stop the inversion driving (step S57) of driving motor 10 at bank note.And this scheduled volume is set at and the bank note rear end is become break away from the rotating speed of conveyance roller to the degree of 12 state.At this moment, bank note is discharged to insert mouthful 6 degree of extracting out from bank note, and the user extracts bank note out, the stage of being detected by banknote detection sensor 18 in the rear end of bank note (step S58), be the stage that banknote detection sensor 18 becomes OFF, LED70 extinguishes, thus end process (step S59).

And, in bank note judges that NG handles, except just with bank note from bank note insert mouthfuls 6 return, as mentioned above, also can not return bank note but send caution signal to epigyny device.In addition, as mentioned above, bank note can be judged that the state of NG in handling is arranged in the counter,, send caution signal in that to count to bank note continuously be counterfeit money and connect under the appendiculate situation.

In above-mentioned steps S54, there be not bank note to judge under the situation of NG processing, carry out the keeping standby and handle (step S60).In the present embodiment, storage position is a bank note by conveyance to the bank note rear end from the line sensor position about side 13mm downstream, in this keeping standby is handled, makes the driving of driving motor 10 stop the schedule time, perhaps makes the transmission of driving force become OFF.

In this keeping standby is handled, because certain is former thereby send under the situation of returning instruction, by making driving motor 10 inversion driving, the bank note that inserted can be inserted mouthfuls 6 from bank note immediately and return (with reference to step S55～step S59).On the other hand,, carry out the conveyance of being undertaken by driving motor 10 and handle by sending processing signals such as piling up instruction, with the direct conveyance of bank note (keeping bank note) that will be in the keeping state to the downstream.

In the present embodiment, as mentioned above, up to insert mouthful bank note that inserts arrival storage position from bank note before (for example banknote detection sensor 18 detects the stage of bank note rear end), drive baffle mechanism 50 sealings, therefore, not only bank note by conveyance after storage position, and in the determinating treatment course of bank note, because bank note inserts mouthfuls 6 and is sealed by baffle mechanism, so can prevent the devious conduct in the bank note determination processing reliably.Promptly, in the past, when the connection attachment carries out devious conduct on bank note, in order to prevent the behavior (closing baffle mechanism), need carry out the identification processing of bank note and the processing of the bank note conveyance being arrived storage position, but in the present embodiment, owing to before storage position, sealed baffle mechanism 50 in conveyance, so can prevent devious conduct reliably.In addition, up to bank note by conveyance before the storage position be in detent position because bank note inserts mouthfuls 6, so the user can not insert bank note continuously, thereby can prevent the bank note paperboard effectively.

And, after inserting bank note,, therefore simplified the treatment step that is used to prevent devious conduct because the sealing of carrying out baffle mechanism with the determination processing of the validity of bank note handles, and carries out the processing of direct conveyance to storage position.

In addition, after the keeping standby is handled, bank note is arrived the downstream by conveyance, detect by the stage of the rear end of the bank note of conveyance by detecting sensor 60 at bank note, being bank note becomes (step S61) behind the OFF by detecting sensor 60, with scheduled volume the driving motor rotation is driven, stop (step S62, S63) then.This scheduled volume depends on that bank note passes through detecting sensor 60 and conveyance roller to 14 distance, and to break away from the conveyance roller corresponding to the rotation amount of the state of 14 clamping with the rear end of bank note.In addition, the driving that makes electromagnet 54 then is OFF (removes energising), and rotatable lamella 52 is drawn in from bank note conveyance path 5, and making bank note insert mouthfuls 6 becomes open state, and LED70 extinguishes, thus end process (step S64).Certainly, also can become stage of OFF by detecting sensor 60, make the driving of electromagnet 54 become OFF (removing energising), and extinguish LED70 at bank note.

Like this,, bank note is in open state usually, so the treatment step when having simplified bill handling because inserting mouthfuls 6.

Bank note treatment device of the present invention also can carry out suitable distortion except above-mentioned treatment step.In addition, baffle mechanism 50 needs only at conveyance bank note and judges in the process of validity, and sealing bank note inserts mouth 6 and gets final product, and for the timing and the opportunity of sealing, can carry out suitable change.

In addition, the identification of bank note is handled and is not limited in above-mentioned embodiment, can carry out various changes.

Promptly, in the present embodiment, when bank note that relatively becomes the judgement object and genuine note, use the transmitted light of infrared light and transmitted light and these four kinds of light sources of reflected light of reflected light and red light to be illustrated, but also can use the transmitted light data of infrared light at least.This moment, preferably as above-mentioned embodiment, wavelength was the wavelength of 950nm or near its value.

In addition, in the above-described embodiment, when carrying out identification, situation about judging by related coefficient is illustrated, but for example also can generates analog waveform, by relatively judging between the shape of this waveform from being subjected to the data behind the light.And then, under the situation that weighting compares, improve the judgement precision thereby also can amplify this waveform.

In addition, in the above-described embodiment, divide into first comparison step and second comparison step is illustrated, in above-mentioned first comparison step, will compare through the transmitted light data and the said reference data of the infrared light of the whole printing zones that become the note surface of judging object; In above-mentioned second comparison step, transmitted light data to the above-mentioned infrared light in the specific region specific in advance in the printing zone of note surface, implement predetermined weighting, data after mutual relatively this weighting between bank note that becomes the judgement object and the above-mentioned genuine note bank note, but also can compare simultaneously with not distinguished.

Promptly, in the identification program, pack in advance comprise the relational expression that is used for weighting relatively use relational expression, use this identification program, transmitted light data at the infrared light of the whole printing zones that see through the genuine note surface, and in the reflected light data of the red light of reflection, data that will weighting in advance in the specific region are as reference data and be stored in the memory storage, on the other hand, in the authenticity determining device that above-mentioned identification program is housed, transmitted light data from the infrared light that sees through the whole printing zones become the note surface of judging object, the perhaps reflected light data of Fan She red light, also carry out the weighting of above-mentioned specific region part concurrently, and compare with the said reference data.

In addition, as compare with the data that in whole printing zones, obtain, to the method that the transmitted light data that obtain from the specific region and reflected light data be scheduled to weighting, can be such method also: the data volume that makes transmitted light data in the above-mentioned specific region and/or reflected light data be than other regional data volume increase.

For example, when using wire ground to be provided with the led array etc. of a large amount of LED, if irradiation is then selected LED to drive the whole LED of driving in the specific region by the zone beyond the specific specific region of coordinate.

Perhaps, also can control the speed of bank note transport mechanism conveyance bank note, make the conveyance velocity ratio slow, thereby increase the data volume of transmitted light data and reflected light data in other zone for by the specific specific region of coordinate.That is, thus make the closeer increase of coordinate density data volume.

In addition, as mentioned above, the bank note treatment device 1 in the present embodiment also can be controlled the conveyance speed of bank note, but also can be by changing luminous interval, promptly changing and deal with sweep time.

In addition, in the present embodiment, carried out identification, but also can use the specific region to judge according to the flow process of step S21 shown in Figure 180～step S28, promptly only set by step S23 and step S24 carry out identification, can also suitably make up other step etc. and judge.
