The present invention relates to a banknote counting apparatus, and relates to a banknote counting apparatus for detecting the presence or absence of a magnetic ink such that the magnetic force emitted from the magnet is less than the magnetic sensor but more than the banknote.

Generally, a bill counter is used to automatically count bills using a mechanical device, and is also used to count not only bills but also securities such as checks.

The banknote counter generally includes a supply roller for supplying a bill therein for counting the bills, a paper feed roller for transporting the bills supplied, a transport roller for transporting the bills fed by the feed rollers and the feed rollers, And a drive motor for driving the feed roller, the feed roller, and the take-out roller, and a counting unit for counting the bills conveyed through such a roller.

Meanwhile, as the counterfeit technology has been developed, various counterfeit detection functions have been incorporated into the bill counter as the bill counter has been required. The banknote counter basically includes a counter sensor. The counter sensor is composed of a light-emitting and a light-receiving infrared sensor, counting the number of bills transferred using infrared light and measuring the thickness of the bills.

In addition, the bill counter is most often equipped with an ultraviolet (UV) sensor to detect whether the banknote is counterfeit. The banknote counter detects the counterfeit by irradiating ultraviolet rays to one side of the banknote being transferred using an ultraviolet sensor. For reference, bills are usually cotton paper, which differs in the amount of ultraviolet light absorbed from other counterfeit bill materials. Accordingly, the banknote counter can detect whether the banknote is counterfeit through the ultraviolet sensor.

In addition, the banknote counting device detects the magnetic ink using a magnetic sensor (magnetic sensor), which is a magnetic ink detection sensor, in order to detect whether the banknote is in most cases.

However, in the related art, the amount of the magnetic ink contained in the banknote is so fine that the magnetic sensor has a considerable difficulty in detecting it. To this end, a magnet for magnetizing the magnetic ink is attached to the part where the bill passes, maximizing the detection of the sensor.

However, the greater the magnetic field strength of the attached magnet, the better the magnetic ink is magnetized, but it also affects the magnetic sensor and involves electronic noise.

In order to solve the above problems, the present invention, by attaching two or more magnets to send a strong magnetic field toward the magnetized portion (banknotes, etc.) and a weak magnetic field toward the magnetic sensor while minimizing the noise associated with the magnetic sensor It is to provide a banknote counting device for detecting the presence or absence of magnetic ink that can maximize the magnetization of the ink.

In order to achieve the above object, the present invention provides an operation unit for a user's operation, a bill input unit for inserting a bill on the upper side of the main body, a display unit for displaying an operation state, and the like. When transferred, the counting means for counting banknotes using a counter sensor or the like, a sensor unit for checking whether the banknotes are pneumatic or counterfeit, a banknote discharging unit for discharging the banknotes counted by the counting means to the outside, the banknote inserting unit A bill conveying roller means for conveying bills from the bill to the bill ejector, and a controller for controlling the overall apparatus and determining whether the counterfeit is in accordance with the sensed value sensed and output from the sensors, and determining the kind of paper. In the banknote counting apparatus including, the said banknote conveying roller means each sheet of banknote supplied from the said banknote input part. Class supplying roller, a paper feed roller for conveying the bills fed, and a roller for export out of the banknotes supplied by the supply roller and the feed roller,

The sensor unit is a magnet unit for magnetizing the magnetic ink printed on the banknote passing through the banknote inserting unit, a magnetic sensor (magnetic ink sensor, magnetic sensor) for recognizing the banknote magnetized by the magnet unit, detects the color information of the banknote A color sensor for detecting, an image sensor for detecting an image formed on the banknote, and a hidden line detecting sensor for detecting the hidden line formed on the banknote,

After dividing the magnet into plural, the divided magnets are bonded to each other,

The magnetic force emitted from the divided magnet extends strongly toward the portion to be magnetized (banknotes, etc.) and slightly toward the magnetic sensor, thereby minimizing noise associated with the magnetic sensor while maximizing magnetization of the magnetic ink.

The magnet is characterized in that it is divided into two in the vertical and / or horizontal direction with respect to the bill entry direction.

In the present invention, the distance between the magnet and the magnetic sensor is preferably 3 ~ 7mm.

If the distance between the magnet and the magnetic sensor is set to less than 3mm, the magnetic field strength of the magnet is greatly affected by the magnetic sensor, and the electromagnetic noise is generated. If the distance between the magnet and the magnetic sensor is set to exceed 7mm, the magnetization by the magnet The magnet ink magnetization of the banknote becomes weak, making it difficult for the magnetic sensor to recognize the magnetization.

The magnetic field strength of the magnet is greatly affected by the magnetic sensor, and the electronic noise is generated.

And / or a control unit 300 for determining a roll type and performing a corresponding process.

The banknote conveying roller means 160 basically includes a feed roller, a paper feed roller, and a take-out roller as described above. In addition, the guide plate 170 also guides the conveying direction of the banknote conveyed by the banknote conveying roller means 160, as described above in FIG.

Since the banknote conveying roller means 160 and the guide plate 170 are also mentioned above, detailed description is omitted here.

The first ultraviolet (UV) sensor 200 and the second ultraviolet sensor 201 are sensors for detecting whether the counterfeit is irradiated with ultraviolet rays to the conveyed bills. The first ultraviolet sensor 200 is installed at a predetermined position of the guide plate 170, and senses the ultraviolet rays reflected by irradiating one surface of the transferred banknote. The second ultraviolet sensor 201 senses the ultraviolet light reflected by irradiating the other surface of the transferred banknote. Preferably, the second ultraviolet sensor 201 senses the ultraviolet light reflected by irradiating the other surface of the banknote which is installed at a predetermined position of the sensor plate 180 described above with reference to FIG. 2.

Such an ultraviolet sensor is a known technical configuration, and for reference, the banknote has a high reflectance with respect to light having a short wavelength in the wavelength range of the light, so the banknote counting device utilizes this characteristic to pay the bill through the ultraviolet sensor. After irradiating ultraviolet light to the amount of light is measured by analyzing the fluorescent material and lipids contained in the bill can be distinguished whether the bill is true or false.

The control unit 300 basically controls the overall bill counter according to the manipulation of the user's control unit 110, and determines whether or not counterfeit and / or the denomination by referring to the memory 400 according to the sensed value to perform the corresponding process. Perform. Memory 400 preferably has a database of information data on the bills of each country in order to distinguish the authenticity of the bills. The information data on the bill is based on the amount of ultraviolet rays absorbed by the bill and the presence or absence of magnetic and the number of the bill, the size of the bill, color information, image information, security thread information, etc., according to the characteristic aspect of the present invention as described below. It includes all the data necessary for the determination of counterfeit, and it also includes the data for classifying notes of paper money.

When the controller 300 determines the counterfeit according to the value sensed by the first ultraviolet sensor 200 and the second ultraviolet sensor 201 with reference to the memory 400, preferably the bill counting operation is stopped and the counterfeit discrimination is determined. Display an error message for the display unit 120. In addition, the control unit 300 may output a buzzer sound for detecting the counterfeit through a buzzer (not shown). Accordingly, the user removes the detected counterfeit from the bill counter.

The controller 300 preferably stops the bill counting operation for a predetermined time and then processes the bill counting operation again. The display unit 120 displays the number of bills that are continuously counted while the bills are counted. If all bills are counted, the display unit 120 displays the number of bills finally counted. At this time, of course, the treated waste water is not included in the displayed water.

According to this aspect of the present invention, the banknote counting device can detect whether the counterfeit is more easily through ultraviolet irradiation on both sides of the bill, and in particular, in the case of peeling counterfeit.

According to a further aspect of the present invention, the banknote counter further includes a transmission ultraviolet sensor. The first ultraviolet sensor 200 and the second ultraviolet sensor 201 described above include all of a light emitting device for detecting a counterfeit through ultraviolet rays reflected and reflected on a bill, but the ultraviolet sensor according to an additional aspect otherwise Is for detecting whether the counterfeit through the ultraviolet rays transmitted through the banknote, the light emitting element and the light receiving element are implemented separately.

That is, the banknote counting device includes at least one light emitting ultraviolet sensor 273 and a light receiving ultraviolet sensor 273 which are installed at a predetermined position of the guide plate 170, and at least one light receiving ultraviolet sensor 273 which is installed to be opposite thereto. A light emitting ultraviolet sensor 271 is included.

Light-emitting ultraviolet sensor 271 and the number on both side plates 170 and 180

It is specified that all of the light ultraviolet sensors 273 are preferably installed. The reason for using such a transmissive ultraviolet sensor is that, for example, in the case of dollars, the transmittance is higher than that of the ultraviolet ray. Since the transmission type ultraviolet sensor is a known technical configuration, detailed description thereof will be omitted.

As described above, the bill counter is irradiated with ultraviolet rays on both sides of the banknote, unlike the conventional one, so that the counterfeit can be easily detected when the ultraviolet ray is irradiated only on one side of the banknote.

According to a further aspect of the present invention, the banknote counter further includes a first magnetic sensor 210. The first magnetic sensor 210 is formed in a plurality of preferably in a rectangular shape at a predetermined position of the guide plate 170, and senses the magnetic distribution formed on one surface of the bill to be transferred. Preferably, the first magnetic sensor 210 is formed to a certain range in the horizontal direction on the guide plate 170 to easily sense the magnetic distribution formed on the bill.

If the magnetic distribution sensed by the first magnetic sensor 210 is less than the reference distribution with reference to the memory 400, the controller 300 outputs an error message and / or a buzzer sound through the display unit 120 indicating the detection of counterfeit. .

According to this aspect of the invention the banknote counting device can additionally detect whether the counterfeit through a magnetic sensor.

According to a further aspect of the present invention, the banknote counter further includes a first color sensor 220. The first color sensor 220 senses color information of one side of a bill to be transferred and installed at a predetermined position of the guide plate 170. In one embodiment, the color sensor receives light reflected from a white light diode that emits light from a specific part of a bill and reflects the light from a color sensor diode including three primary colors (blue, red, and green) of the bill. That is, it is configured to sense the color. The control unit 300 may detect whether the forgery is modified as well as the paper type of the bill from the color information sensed by the first color sensor 220 as described above.

Briefly describing the banknote classification, first, the control unit 300 initially stores the winding type data of the first banknote to be transferred as a set value, and detects it according to the sensed value when the different winding types are transferred. If necessary, the controller 300 may notify the user by outputting the display unit 120 and / or a buzzer sound. The control unit 300 proceeds the counting operation again after stopping the predetermined time counting operation, and adds the bills counted for each kind of book. Since such technology is well known, a detailed description thereof will be omitted.

According to this aspect of the present invention, the banknote counting device may detect not only the banknote classification but also additional forgery and alteration through the color sensor.

In accordance with a further aspect of the present invention, the banknote counter includes a first image sensor 230. The first image sensor 230 senses an image of at least a portion of one side of the banknote installed and transported at a predetermined position of the guide plate 170, and preferably senses an entire image of one side of the banknote. The image sensor may be a contact image sensor (CIS) in one preferred embodiment. The CIS may sense a kind of paper money by sensing at least a portion of an image of one side of a paper money, and in particular, may sense a unique serial number among the paper money images to distinguish a paper money serial number.

For reference, the CIS is a small image input device that scans an object (Document, etc.) that adheres to the glass surface of the unit and converts the data into data.

The CIS has a resolution of more than 200 dpi and includes a light source (RGB light source), a lens (Rod lens), a photo sensor (Sensor Chip) and other electronic components that output a video signal.

The light is emitted from the RGB light source to the focal point set on the glass surface, and the light reflected from the banknote on the glass surface is directed into the unit through the lens. The light reaches a photo sensor (Sensor Chip), and is converted into an electrical signal of an analog type on a circuit board (PCB) provided with the photo sensor and a microprocessor (pointing to the control unit 300). The output analog signal is converted into a digital signal and input to the controller 300.

As described above, the control unit 300 detects whether the paper currency is classified and additionally counterfeit according to the memory 400 and performs a control process accordingly.

According to this aspect of the invention the banknote counting device can determine the counterfeit through the image sensor, it is also possible to classify the kind.

According to a further aspect of the present invention, the banknote counter further includes a first hidden line detection sensor 240. The first hidden line detecting sensor 240 is a means for sensing a hidden thread formed on the banknote. The silver wire is difficult to forge with a thin strip-shaped wire made of plastic or metal with a width of about 0.5 to 3 mm placed vertically in the banknote, and therefore, a considerable effect can be expected in preventing forgery. For reference, a simple metal-deposited silver line is inserted in the old world and a holographic silver line is inserted in the newly issued priesthood.

Hidden wires can be manufactured in partially exposed (windowed thread) or completely embedded in paper (hidden hidden wire), as in the full circle. In addition, there are various forms of the hidden line according to the manufacturing method and function provision, and there are fine letter hidden line, silver line partially removed metal layer, colored letter combination silver line, ultra thin metal + colored silver line.

The hidden line detection sensor, called a metal thread sensor or a security sensor, can sense a fluorescent or magnetic material applied to the surface of a hidden line formed on a bill, or sense a difference in a printed pattern in a horizontal or vertical direction. Or you can sense the spacing, patterns, letters, etc. of hidden lines. Since the hidden line detection sensor, which is a means for detecting the authenticity of the hidden line, is a known configuration, detailed description thereof will be omitted.

According to this aspect of the invention the banknote counting device can additionally determine whether the counterfeit through a hidden line sensor.

According to a further aspect of the present invention, the banknote counter further includes a size sensor 250. The size sensor 250 is installed at a predetermined position of the guide plate 170 to sense the size of the bill to be transferred, and includes at least one pair of size light receiving / emitting sensors installed opposite thereto.

For example, the size sensor 250 may include at least one first size light receiving sensor 251a and a second size light emitting sensor 253b including a plurality of light receiving sensors in a row at a predetermined position of the guide plate 170 in a horizontal direction. And a first size light emitting sensor 251b and a second size light receiving sensor 253a at positions opposite thereto. According to a preferred aspect, the first size light-receiving sensor 251a and the second size light-receiving sensor 251a and the second size light-receiving sensor 253b respectively disposed on the guide plate 170 are disposed to face each other. 253a is installed on the sensor plate 180.

The size sensor 250 configured as described above is for detecting the horizontal size of the banknote. Since the size sensor 250 having such a configuration is a known technology, detailed description thereof will be omitted. According to this aspect of the present invention, the banknote counting device can determine whether the counterfeit through the size sensor 250, and in particular in this case, because the size difference is a lot, it is also easy to classify the paper type.

FIG. 4A is a view showing a guide plate disposed inside a conventional banknote counter and having sensors disposed thereon, and FIG. 4B is a diagram illustrating a magnetic force line distribution emitted from a magnet of the conventional banknote counter. In addition, Figure 5a is a view showing a guide plate located inside the banknote counting device according to an embodiment of the present invention, the sensor is disposed, Figure 5b is emitted from the magnet of the banknote counting device according to an embodiment of the present invention 5 is a diagram illustrating a magnetic force line distribution, and FIG. 5C is a diagram illustrating a magnetic force line distribution emitted from a magnet of a banknote counting device according to an embodiment of the present invention. 4A and 5A show only a part of the sensor (eg, a magnet, a magnetic sensor, etc.) on the guide plate.

As mentioned above, in the related art, the amount of the magnetic ink contained in the banknote is so small that the magnetic sensor has a considerable difficulty in detecting it. To this end, a magnet for magnetizing the magnetic ink is attached to the area where the bill passes, maximizing the detection of the sensor. That is, as shown in Figure 4a, the bill (not shown) is gradually lowered in the direction of the magnet 10 in the state located on the guide plate 170 of the bill counter, the magnet 10 is the bill Magnetized, and the magnetized banknote enters the magnetic sensor (magnetic sensor) 11. However, if the strength of the magnetic force emitted from the magnet 10 is too weak, the magnetic sensor 11 is not possible to check the magnetism, if the strength of the magnetic force emitted from the magnet 10 is too strong, the magnetic force is the magnetic sensor 11 This also affected electronic noise.

Accordingly, in the present invention, a single magnet is divided into a plurality of parts, and the divided magnets are bonded to each other so that the magnetic force emitted from the divided magnets extends strongly toward the magnetized part (banknotes, etc.) and the magnetic sensor (magnetic sensor). Towards a weak side.

That is, as shown in FIG. 5, in the present invention, one magnet is divided into two 261 and 262, and the divided magnets 261 and 262 are connected again. More specifically, in FIG. 5A and FIG. 5B, one magnet 10 as shown in FIG. 4 is divided into two equal parts in a direction perpendicular to the banknote entering direction, and in FIG. 5C, the magnet as shown in FIG. It is divided into two in parallel direction.

Looking at the distribution of the magnetic field lines emitted from the magnets of the prior art (see FIG. 4b) and the present invention (see FIGS. 5b and 5c), it can be seen that the magnetic field distribution is uniform and concentrated within a certain distance than the prior art. have. That is, in the case of FIG. 4B, the lines of magnetic force are far apart, while in FIG. 5B and 5C, the lines of magnetic force are not far apart from FIG. 4B. This means that the magnetic flux flux density is greater within a certain distance than the prior art. In other words, the sum of the magnetic forces in the case of one magnet and in the case of two divided magnets is the same, so that the magnetic force emitted from the magnet is less than the magnetic sensor in the present invention than in the prior art.

Accordingly, in the present invention, it is possible to maximize the magnetization of the magnetic ink while minimizing the noise accompanying the magnetic sensor.

Of course, in the present invention, an example of dividing a magnet into two is given as an example, but the present invention is not limited thereto, and includes four and eight portions.

In the present invention, the distance between the magnet and the magnetic sensor is preferably 3 ~ 7mm.

In the case of the banknote counting device currently used, the distance between the magnet and the magnetic sensor is about 5 mm. In the present invention, the experiment was performed while adjusting the distance between the magnet and the magnetic sensor little by little, and the following results were obtained. In other words, if the distance between the magnet and the magnetic sensor is set to less than 3mm, the magnetic field strength of the magnet is greatly affected by the magnetic sensor, and the electronic noise is generated. Also, if the distance between the magnet and the magnetic sensor is set to exceed 7mm, the magnet is caused by the magnet. The magnet ink magnetization power of the magnetized banknote was weak, making it difficult for the magnetic sensor to recognize the magnetization. Therefore, in the present invention, the distance between the magnet and the magnetic sensor is preferably set to 3 to 7 mm.

As described above, with reference to the preferred embodiment of the present invention, those skilled in the art will be variously modified without departing from the spirit and scope of the present invention described in the claims below And can be changed.

As described above, in the present invention, by splitting a plurality of magnets magnetizing the bills in the bill counter, the divided magnets are joined together, and the magnetic force emitted from the divided magnets is magnetized (banknotes, etc.). By sending it hard to the side and weak toward the magnetic sensor, the magnetization of the magnetic ink can be maximized while minimizing the noise associated with the magnetic sensor.
