Ultraviolet (UV) sensor, which performs a counterfeit detection function, detects a counterfeit by irradiating ultraviolet rays to one side of a bill to be transported. Since banknotes are usually made of cotton fibers, they differ in the amount of UV light absorbed from forged banknote materials. Accordingly, the banknote counter can detect whether the banknote is counterfeit through the ultraviolet sensor.

However, the detection of counterfeit using the existing ultraviolet sensor detects the counterfeit through only one side of the bill and detects the counterfeit through data (ultraviolet dose) obtained from the bill, but the amount of ultraviolet light is measured differently according to the fine cotton fiber tissue form of the bill. Occurs and there is a problem that leads to the misdetection of the counterfeit.

In addition, recently, due to the high risk of issuing counterfeit bills due to the issue of high value money, it is urgent to develop a banknote counter that can more accurately discriminate counterfeit money.

Counterfeit discrimination banknote counter 100 using a plurality of ultraviolet sensors according to the present invention is a detection means for determining whether the banking means 120 and the counting means 120 for counting the transferred banknotes and the banknotes of the banknotes inserted In the banknote counter configured to count the inserted banknotes, including the means 300 and to determine whether or not, the sensing means 300, the first and second irradiation unit for irradiating ultraviolet rays from one side and the other side of the banknotes (310, 330), the first and second ultraviolet sensors (320, 340) for detecting the amount of reflection or transmission of ultraviolet rays irradiated to the first, second irradiation unit and the value measured by the first ultraviolet sensor and the second ultraviolet ray When the measured value satisfies the reference value in the sensor, it is determined as the pneumoconiosis, and if any one value does not satisfy the reference value, the controller 200 may be configured to determine as a counterfeit.

First, referring to the general configuration of the bill counter 100, although not shown in detail in the drawings, the conveying means 110 is to sequentially transport the bills to count the bills placed, the supply roller for supplying the bills placed in the input section And a paper feed roller for transferring the supplied paper money, and a transport roller for carrying out the paper money supplied by the feed roller and the paper feed roller, and finally discharged to the discharge portion.

The counting means 120 counts the number of bills using a sensor such as a counter sensor to count bills supplied by the conveying means. When the user places a large amount of bills in the input unit and executes a counting command through the operation unit 130, the bills are counted by the counting means while being transferred inside each sheet by the transport means 110.

In addition, the bill counter 100 is a display unit 140 for displaying the number of bills counted, the counting environment setting through the operation unit 130 is displayed through a display device such as an LCD panel or seven segments, the environment by the operation unit A memory 150 capable of storing data such as settings and coefficient accumulation is configured.

The controller 200 basically controls the banknote counter 100 in accordance with the operation of the manipulation unit 130, and processes the data for determining whether the counterfeit is present or the paper type by referring to the memory 150 according to the detected value. . On the other hand, the memory 150 stores the information data about the bills of each country, the user may input bill information through the operation unit.

Here, the information data on the bill includes reference ultraviolet absorbance, magnetic presence, bill size, color information, image information, hidden thread information, and the like.

Sensing means 300 is a configuration for detecting whether or not when counting banknotes. Various techniques are currently applied to the sensing means, and typical examples include a size sensor for measuring the size of a banknote, a color sensor for detecting the color of a banknote, a hidden wire sensor for detecting a security thread, and a magnetic sensor for detecting the presence or absence of a magnetic. It is configured to include.

In addition, it corresponds to the main technical gist of the present invention, and further includes a plurality of ultraviolet sensors in order to detect the amount of ultraviolet rays transmitted or reflected.

The ultraviolet sensor is provided with a first ultraviolet ray sensor 320 and a second ultraviolet ray sensor 340 on one side and the opposite side of the banknote, respectively, and the first irradiating portion 310 and the second irradiating portion that irradiate ultraviolet rays correspondingly. 330 is installed.

The first and second ultraviolet sensors 320 detect the counterfeit through the amount of transmission or reflection after irradiating ultraviolet rays to the bill. Since banknotes have high reflectivity for short wavelengths of light in the wavelength range of light, by applying ultraviolet rays to the banknotes through ultraviolet sensors using these characteristics, the amount of light is measured to analyze fluorescent materials and lipids contained in banknotes. Detect whether or not it is a fake.

In addition, in case of bills of other countries (eg, dollars), the transmittance is higher than that of ultraviolet rays, and thus the amount of ultraviolet rays is measured according to the characteristics of different bills. In one embodiment, the irradiation unit may be configured as an LED for irradiating light in the ultraviolet region, the ultraviolet sensor may be configured as a light receiving unit for detecting the level of ultraviolet light by detecting the light emitted from the irradiation unit.

In detail, both sides of the passage 350 through which the banknotes supplied by the transfer means 110 pass to the first and second irradiation units 310 and 330 and the first and second ultraviolet sensors 320 and 340. The transmission amount or reflection amount of ultraviolet rays irradiated to the banknote is measured.

When describing the UV measurement method in detail, first, in order to confirm the transmission amount measurement value, when the ultraviolet rays irradiated to the first irradiation unit transmits from one side of the bill, the first ultraviolet sensor 320 installed on the opposite side measures the transmission amount. Similarly, when the ultraviolet rays irradiated from the second irradiator 330 transmits from the opposite side of the banknote, the transmission amount is measured by the second ultraviolet sensor 340, and it is determined that the reference value, that is, the ultraviolet ray level is less than the reference value, is counterfeit.

In this case, the first inspection unit corresponds to the first irradiation unit and the first ultraviolet sensor, and the second inspection unit corresponds to the second irradiation unit and the second ultraviolet sensor.

The sensing means 300 for ultraviolet detection are installed at staggered positions, respectively. The first irradiation part and the second ultraviolet sensor are provided on one side, and the second irradiation part and the first ultraviolet sensor are installed on the other side.

This is to measure the amount of reflection as well as the amount of transmission. When the amount of reflection of the ultraviolet rays irradiated on the banknote is to be measured, the ultraviolet rays irradiated from the first irradiation unit are reflected back from the banknote, and the second ultraviolet sensor 340 measures it. The amount of reflected ultraviolet light is measured by the first ultraviolet sensor 320.

In this case, unlike the measurement of the transmission amount, the first inspection unit (the first irradiation unit and the second ultraviolet sensor) performs the inspection first, and then the second inspection unit (the second irradiation unit and the first ultraviolet sensor) is implemented. In addition, a separate driving means 220 is provided in order to easily acquire the reflectance, so that the interval between the first irradiator and the second ultraviolet sensor and the second irradiator and the first ultraviolet sensor may be narrowed and operated.

Therefore, it is possible to detect whether the counterfeit is more accurate by measuring the transmission amount or the reflection amount according to the type of banknote, and since it is performed on both sides of the banknote, it is possible to achieve even higher detection power.

As described above, a separate mode switching unit 210 is further provided to determine the measurement of the transmission amount or the reflection amount. The mode switching unit 210 is selected by the user selectively through the operation unit, or irradiated with ultraviolet rays to the first counting bill, if the transmission amount or the amount of reflection is extremely fine, that is, if the transmission amount or the amount of reflection does not significantly exceed the reference value, the mode accordingly Switch automatically. If the amount of transmission is fine, it is switched to the reflection measurement mode, and if the amount of reflection is minute, it is switched to the transmission measurement mode.

Therefore, depending on the type of bill, the user can automatically detect the counterfeit by measuring the amount of reflection or the amount of transmission according to the characteristics of the bill without additional manipulation.

According to the present invention configured and operated as described above, a plurality of ultraviolet sensors may be used to increase the usability by measuring a transmission amount or a reflection amount according to the type of bill. In addition, there is an advantage that can be solved by errors of the microstructure of the banknote by irradiating ultraviolet rays from both sides.

As described above and described with reference to a preferred embodiment for illustrating the principle of the present invention, the present invention is not limited to the configuration and operation as shown and described as such.

Rather, it will be apparent to those skilled in the art that many changes and modifications to the present invention are possible without departing from the spirit and scope of the appended claims. And all such modifications and changes as fall within the scope of the present invention are therefore to be regarded as being within the scope of the present invention.
