In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

 1 shows an embodiment of a configuration of a banknote processing apparatus according to the present invention and shows the inside of a device capable of performing counting, counterfeit detection and damaged banknote detection for one or more banknotes to be inputted .

Referring to FIG. 1, the banknote handling apparatus 10 includes rollers 110 for sequentially feeding a plurality of banknotes stacked on the input unit 140 and feeding the banknotes one by one, And may include transfer sensors 120.

For example, the rollers 110 may include a main-feed roller for feeding bills, a kicker roller for separating the stacked bills into sheets and delivering the bills to the main-feed roller, a push roller, a reverse roller for pushing the upper sheet in the opposite direction and separating it into a sheet when two or more bills are transported together, and the like

The conveyance sensors 120 include an input sensor for detecting whether or not the paper money to be separated and fed is separated and a jam sensor for detecting a jam of paper money in the middle of the conveyance path T .

The banknote processing apparatus 10 includes a recognition unit (not shown) for sequentially recognizing the inputted bills and outputting a recognition result corresponding to at least one of the denomination of the bills, whether the bills are counterfeit, and whether the bills are damaged or not.

The recognition unit is located adjacent to the conveyance path T of the bill to be conveyed to detect recognition of the denomination of the bill, detect whether it is falsified, detect whether the bill is damaged or not and detect recognition bills 130 ). ≪ / RTI >

The recognition sensors 130 may include a CIS image sensor to acquire an image of each banknote to be conveyed and to extract banknote characteristic information in the obtained image to recognize the denomination.

In addition, the recognition sensors 130 may include an infrared (IR) sensor, a UV sensor, a magnetic (MG) sensor, a CIS sensor, or the like for detecting various counterfeit elements formed on the bill.

In addition, the banknote handling apparatus 10 includes an anti-stokes sensor for detecting Anti-Stoke's luminescent material formed in a specific region of a banknote for detecting counterfeit money.

The anti-stokes luminescent material is a luminescent material capable of emitting light in a visible light range when it is excited by infrared rays (IR), wherein the rotation line of Raman spectrum is referred to as a Raman line and a line appearing on a longer wavelength side than the incident light is referred to as a stoke line The line appearing on the wavelength side is called an anti-Stokes line.

The Raman spectrum is a spectrum of scattered light due to the Raman effect, and the spectrum in the case where the energy difference between the vibration levels of the ground state of the molecules occurs between the incident photon and the molecule is referred to as a vibrational Raman spectrum.

In this case, since the transition between the rotation levels is also related, it is also referred to as a Raman rotation vibration band, and the change in the quantum number of vibrations is strongly exhibited. On the other hand, the spectrum when the energy difference between the rotation levels within the lowest vibration level of the floor condition occurs is called the rotating Raman spectrum.

On the other hand, the normal bills determined to be non-counterfeit by the above-described structure are stacked on the stacker 150, and the abnormal bills, such as the counterfeit or the denomination can not be identified, 160, respectively.

The recognition unit provided in the banknote processing apparatus 10 can detect the thickness of a banknote using an ultrasonic US sensor and confirm whether or not a tape is attached to the banknote according to the detected banknote thickness.

1, the ultrasonic transmitter 131 and the ultrasonic receiver 132 may be disposed opposite to each other with the paper money transport path T therebetween. The ultrasonic receiver 132 may include an ultrasonic transmitter 131, It is possible to receive the ultrasonic wave transmitted from the banknote and transmitted through the banknote.

As a result of checking using the ultrasonic sensor, if the bills are judged to be damaged bills such as a tape adhered to the bills, the bills can be discharged to the reject pocket 160.

In addition, whether or not the banknote is damaged can be detected by detecting a torn or perforated banknote using a CIS image sensor, detecting a jippe in water by using an ultraviolet (UV) sensor, or graffiti using an infrared (IR) sensor The bill can be identified by detecting the bill.

The configuration of the banknote handling apparatus 10 described with reference to FIG. 1 is according to an embodiment of the present invention, and the present invention is not limited to this, and various configurations may be possible as needed.

For example, as shown in FIG. 2, the charging unit 141 and the discharging units 161, 162, and 163 of the banknote processing apparatus 10 may be configured as pockets inside the apparatus.

In this case, the banknotes stacked on the input unit 141 are recognized as denomination, counterfeit, or damaged by the recognition unit, and are classified into a plurality of stacking pockets 161, 162, and 163 according to the recognition result, .

3 is a view for explaining an embodiment of a method of recognizing whether or not a tape is attached by detecting the thickness of a banknote using the ultrasonic sensor in the recognition part of the banknote processing apparatus 10. [

3, the recognition unit included in the banknote processing apparatus 10 may include an ultrasonic transmission unit 300 and an ultrasonic reception unit 320 disposed at positions opposite to each other with a banknote A being conveyed therebetween .

The ultrasonic wave transmitted from the ultrasonic transmission unit 300 can be received by the ultrasonic reception unit 320 after the bill A passes through the paper currency A while the paper currency A passes between the ultrasonic transmission unit 300 and the ultrasonic reception unit 320. [

The thickness of the banknote A can be detected according to the intensity of the ultrasonic wave received by the ultrasonic receiving unit 320. For example, the thickness of the banknote A may be calculated to decrease as the intensity of the received ultrasonic wave decreases .

3, when the tape P is attached to one area of the banknote A, the intensity of the ultrasonic wave received by the ultrasonic wave receiver 320 in the region where the tape P is attached is It can be judged that the thickness of the banknote A is large, because it is measured weakly in the other region.

Therefore, when the intensity of the ultrasonic wave received by the ultrasonic receiver 320 is smaller than a predetermined reference value in a certain region, it can be determined that the tape is attached to the paper money A and can be detected as a damaged paper money.

However, since the thickness and the material of the banknote differ depending on the denomination (the issuing country and the amount of the banknote) of the banknote, the reference value used for the tape detection may be set differently according to the denomination of the banknote A.

For this purpose, the banknote handling apparatus 10 first recognizes the denomination of the banknote A prior to the tape detection, compares the reference value corresponding to the recognized denomination with the intensity of the ultrasonic wave received by the ultrasonic receiver 320 Whether or not the tape is attached to the banknote A can be confirmed.

However, the ultrasonic receiving unit 320 may include a plurality of ultrasonic receiving sensors aligned in one direction, so that the exact thickness of the paper currency A may not be detected due to interference between ultrasonic receiving sensors adjacent to each other.

4, the ultrasound transmitting unit 300 includes a plurality of ultrasound transmitting modules 301 to 305, and the ultrasound receiving unit 320 includes a plurality of ultrasound transmitting units 301 to 305 corresponding to the ultrasound transmitting modules 301 to 305, And includes reception sensors 321 to 325.

Here, the ultrasonic transmitting module and the ultrasonic receiving sensor, which correspond to each other, transmit and receive ultrasonic waves and measure the intensity of the ultrasonic waves received by the ultrasonic receiving sensor, whereby the thickness of the corresponding position in the paper currency A can be detected.

4, the ultrasonic waves transmitted from the first ultrasonic transmission module 301 corresponding to the area where the banknote A is not positioned do not pass through the banknote A, The ultrasonic waves reaching the ultrasonic reception sensor 321 and the strong ultrasonic waves not passing through the paper money A can be received up to the second ultrasonic reception sensor 321 positioned adjacent thereto.

In this case, the ultrasonic waves received by the second ultrasonic reception sensor 321 are transmitted to the ultrasonic waves transmitted from the second ultrasonic transmission module 302 and passed through the banknote A, from the ultrasonic waves transmitted from the first ultrasonic transmission module 301 The intensity of the ultrasonic waves is increased, and the thickness detection for the corresponding part of the banknote A may not be performed accurately.

According to an embodiment of the present invention, when detecting the thickness of a banknote using the ultrasonic sensor, a part of the ultrasonic transmission modules are operated according to the width of the banknote, whereby the thickness of the banknote is detected incorrectly by interference with the adjacent sensor Therefore, the performance of the bill processing apparatus can be improved.

FIG. 5 is a block diagram showing a part of the configuration of a bill processing apparatus according to an embodiment of the present invention, and shows only a configuration for detecting the thickness of a bill using the ultrasonic sensor among the configurations of the bill processing apparatus.

The description of the same components as those described with reference to Figs. 1 to 4 of the configuration shown in Fig. 5 will be omitted below.

5, the bill processing apparatus may include an ultrasonic transmission unit 300, a denomination recognition unit 310, an ultrasonic reception unit 320, a thickness detection unit 330, and a control unit 340.

The denomination recognizing unit 310 can recognize the denomination of the banknote using the obtained banknote images for each of the inputted banknotes.

For example, the denomination recognition unit 310 acquires the image of the bill A using the CIS image sensor, extracts the outline of the bill from the obtained image, calculates coordinates from the image of the bill within the outline, The denomination of the banknote can be determined by comparing characteristic values of a plurality of predetermined areas (for example, the color or brightness average value of the corresponding area) with the characteristic values of the pneumatic pressure using the calculated coordinates.

Meanwhile, the denomination of the banknote may be inputted from the user.

The control unit 340 receives information on the recognized denomination through the denomination recognition unit 310 and receives a plurality of ultrasonic waves transmitted from the ultrasonic transmission unit 300 based on the paper currency width corresponding to the input denomination information Some of the modules 301 to 305 can be selected and operated.

For example, the control unit 340 may operate only a part of the ultrasonic transmission modules corresponding to the position of the paper currency to be transferred among the ultrasonic transmission modules 301 to 305 to transmit the ultrasonic waves toward the paper currency, The remaining ultrasonic transmission modules at nonexistent locations may not transmit ultrasonic waves.

When the ultrasound waves transmitted from the selected ultrasound transmission modules and transmitted through the banknote A are received by the ultrasound reception sensors, the thickness detector 330 detects the thickness of the paper money B according to the intensity of the received ultrasound, (A) can be detected.

Hereinafter, embodiments of a method for controlling an operation of the bill processing apparatus according to the present invention will be described in detail with reference to FIGS. 6 to 8. FIG.

The control method shown in FIG. 6 is a flowchart of a bill processing apparatus according to an embodiment of the present invention, Will be described in conjunction with block diagrams.

6, the denomination recognition unit 310 recognizes the denomination of the banknote using the banknote image (step S600), and the controller 340 detects the width of the banknote according to the recognized denomination (step S610) .

As described above, since the width W of the banknote may be different according to the denomination (the issuing country and the amount of the banknote) of the banknote, the controller 340 controls the memory (not shown) By using the denomination-denominated denomination information stored in the denomination-denominated denomination denomination DB.

Thereafter, the controller 340 selects a portion of the plurality of ultrasonic transmission modules 301 to 305 to transmit ultrasonic waves based on the detected paper currency width in step S610 (S620).

7, when the paper money A is conveyed and enters between the ultrasonic transmission unit 300 and the ultrasonic reception unit 320, the number of the ultrasonic transmission modules corresponding to the width W of the paper money A, The first and second ultrasonic wave transmitting modules 301 and 302 can be operated by the controller 340 to transmit ultrasonic waves.

On the other hand, the remaining ultrasonic transmission modules, for example, the third to nth ultrasonic transmission modules 303 to 305, which are out of the width W of the banknote A, do not transmit ultrasonic waves, The reception sensors 301 and 302 may not be affected by ultrasonic waves transmitted from adjacent ultrasonic transmission modules and not transmitted through the banknote A,

As the bill A is continuously conveyed, the ultrasonic transmission modules operated by the control unit 340 are changed. In the case shown in FIG. 8, the operation of the first ultrasonic transmission module 301 is ended, The second and third ultrasonic wave transmitting modules 302 and 303 may be operated by the control unit 340 to transmit ultrasonic waves toward the banknote A. [

The plurality of ultrasonic receiving sensors 321 to 325 receive ultrasonic waves transmitted from the selected ultrasonic transmission modules and transmitted through the banknote A in step S630 and the thickness detector 330 detects the ultrasonic waves received from the ultrasonic transmission modules 321 to 325 in step S630 The thickness of the banknote A is detected (step S640).

At least some steps of the operation control method of the banknote handling apparatus according to the present invention may be stored in a computer-readable recording medium made of a program to be executed by a computer, and examples of the computer readable recording medium include A ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet).

The computer readable recording medium may be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And, functional programs, codes and code segments for implementing the above method can be easily inferred by programmers of the technical field to which the present invention belongs.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
