The passbook input port 3d and the card input port 3e are arranged, respectively.

The display input screen 3a is composed of a display unit for displaying the amount of money to be traded, an account number, transaction processing contents and the like, and an input unit such as a touch panel for inputting an amount of money, an account number and the like and a predetermined process. For example, when a predetermined amount of money is transferred to a designated account, when a predetermined amount of money and an account number are input to the touch panel by the user, the amount of money and the account number are displayed on the display unit. The user checks the displayed transaction details and if there is no abnormality, the user can proceed with this transaction with the touch panel. If there is a problem, the amount and account number can be re-entered using the touch panel.

When a coin is deposited by the user in the coin inlet 3b, the kind, authenticity, etc. of the coin deposited are discriminated in the banknote processing apparatus 3. According to the authenticity discrimination result, the genuine coin is conveyed to the coin storage of the predetermined gold kind arrange | positioned inside the banknote processing apparatus 3. The fake coin is returned to the user from the coin inlet 3b. Further, according to the user's manipulation input through the display input screen 3a, coins of the desired amount of money are returned to the user from the coin inlet 3b.

When a banknote is thrown in by the user in the banknote inlet 3c, the kind, authenticity, etc. of the banknote which were put into the banknote processing apparatus 3 are discriminated. According to the discrimination result, genuine banknotes are conveyed for each kind of paper to a predetermined stacker arranged in the banknote processing apparatus 3. The fake bills are returned to the user from the bill slot 3c. In addition, the discrimination process of a banknote state is mentioned later. In addition, according to the user's operation input through the display input screen 3a, the bill of the desired amount of money is conveyed from the stacker and returned to the user from the bill input port 3c.

Next, each function of the host computer 2 and the banknote processing apparatus 3 which comprise the banknote discrimination system 1 is demonstrated.

Fig. 2 is a block diagram showing the functions of the host computer and the banknote processing apparatus in the first embodiment, respectively.

First, the host computer 2 includes a storage unit 21, a communication unit 22, a discriminating unit 23, and a central processing unit (CPU) 24.

The master template is stored in advance in the storage 21. The master template is composed of characteristics such as the appearance of gold coins of the true denomination banknote, the shape of a printed pattern, and the shade of light. For example, the master template of a banknote is a vertical and horizontal length (or normalized length and horizontal length in normal banknotes in the case of four insertion directions of front and back and top and bottom with respect to the banknote processing apparatus 3). The gradation degree in each area | region which divided the whole banknote by the micro area | region, and the thickness of one banknote etc. are mentioned later. In addition, even if the banknotes are in circulation, there are fluctuations in characteristic values such as appearance, print shape, and shades. If the master template is strictly corresponded only to the true lottery, the differentiation method using the master template described later may not accurately discriminate even gold grades such as the true lottery. Thus, each characteristic value constituting the master template has a width within an allowable range, for example, a normal distribution. Such master templates are prepared corresponding to 1,000 yen bills, 5,000 yen bills, and 10,000 yen bills, respectively. In addition, the master template stored in the storage unit 21 can be updated as necessary.

The communication part 22 is connected to the banknote processing apparatus 3 by the network 4 which can communicate, and transmits and receives information with respect to the banknote processing apparatus 3.

The banknote detecting unit 32 detects that the banknote put into the predetermined conveying path by the user from the banknote inlet 3c of the banknote processing apparatus 3 is notified, and notifies the CPU38 of this detecting.

According to the operation instruction received from the CPU 38 notified of the detection of the conveyance of the bill, the sensor unit 33 has characteristics such as the size and appearance of the bill, the shape and shade of the printed form, the thickness, and the thickness of the bill from the entire surface of the conveyed bill. Read it. And the sensor part 33 produces | generates image information from the characteristic of the banknote which read. In addition, the sensor unit 33 may be composed of an optical sensor, a thickness sensor, a magnetic sensor, and the like, depending on the characteristic to be read. Further, the optical sensor generates image information of the banknote by the transmitted light and the reflected light of the light irradiated on the conveyed banknote, the thickness sensor detects the thickness from the displacement amount in the thickness direction by the conveyed banknote, the magnetic sensor is the magnetic Create an image. In addition, the banknote reading by the sensor part 33 is mentioned later again, giving a specific example.

The amplifying unit 34 amplifies the image information of the bill generated by the sensor unit 33.

The A / D converter 35 converts the image information amplified by the amplifier 34 into digital information. The image processing unit 36 performs image processing such as coordinate transformation (tilt correction) and density correction on the image information converted into digital information.

The communication unit 37 is connected to a network 4 capable of communicating with the host computer 2, and transmits and receives information to and from the host computer 2.

CPU 38 controls the conveyance mechanism of the banknote in banknote processing apparatus 3 according to a user's operation input. The CPU 38 further includes a bill detector 32, a sensor 33, an amplifier 34, an A / D converter 35, an image processor 36, and a communication unit included in the bill processor 3. (37) and the like are controlled. In particular, when the detection from the banknote detecting unit 32 is notified, the CPU 38 transmits an operation command to the sensor unit 33 to operate the sensor unit 33. In addition, the CPU 38 transmits the image information processed by the image processing unit 36 from the communication unit 37 to the host computer 2. Moreover, the CPU 38 controls the conveyance mechanism of the banknote in the banknote processing apparatus 3 according to the discrimination result in the host computer 2.

The differentiation method of the banknote inserted into the banknote processing apparatus 3 which consists of the banknote discrimination system 1 which has the host computer 2 and the banknote processing apparatus 3 provided with such a structure, respectively is demonstrated.

It is a flowchart which shows the discrimination process of banknotes performed by the banknote discrimination system in 1st Embodiment. 4 is a figure for demonstrating the reading process of the image information of the banknote which consists of a banknote discrimination system, and FIG. 5 is a figure for demonstrating the image process of the banknote which is performed by a banknote discrimination system.

3, the process of step S11-S13 is performed by the banknote processing apparatus 3, and the process of step S14-S17 is performed by the host computer 2, respectively. 4 shows a case where the banknote Q is rotated and conveyed from the conveyance path 331 in the X direction. 5 (A) shows an image of the entire bill (Q) face read and generated by the sensor unit 33, and FIG. 5 (B) shows an image process on the entire face of the bill (Q). Each image is shown.

A description with reference to FIGS. 2 and 3 to 5 is as follows.

First, the banknote Q injected from the banknote insertion port 3c of the banknote processing apparatus 3 is conveyed by the conveyance path 331 arrange | positioned inside the banknote processing apparatus 3, as shown in FIG. In addition, conveyance of the banknote Q in the conveyance path 331 is performed by the conveyance mechanism not shown in the inside of the banknote processing apparatus 3 which is not shown in figure.

Position sensors 334a to 334d and optical sensors 332 are disposed on the conveyance path 331. In addition, the banknote Q injected by the user from the banknote inlet 3c is conveyed toward the X direction in the conveyance path 331. As shown in FIG.

The position sensors 334a to 334d are part of the components of the banknote detector 32. The position sensors 334a and 334b are arrange | positioned in the conveyance surface of the conveyance path 331 before the banknote Q is conveyed to the optical sensor 332, and detect conveyance of the banknote Q to the optical sensor 332. The detection result is notified to the CPU 38. In addition, the position sensors 334c and 334d are arrange | positioned in the conveyance surface of the conveyance path 331 after banknote Q is carried out from the optical sensor 332, and carry out carrying out of the optical sensor 332 of the banknote Q is carried out. Detect.

The optical sensor 332 is a part of the component of the sensor part 33, and the light emitting part and the light receiving part (both not shown) are opposingly arrange | positioned with the conveyance path 331 up and down, respectively. When the optical sensor 332 receives an operation instruction from the CPU 38 notified of the detection of the bill Q from the position sensors 334a and 334b, the surface of the bill Q is conveyed by the transport path 331. The light is irradiated to it, and the characteristics such as the size and appearance of the banknote Q, the shape of the printed form, the shade and the like are read from the transmitted light on the entire surface of the banknote Q at that time. Image information of the banknote Q is generated from the read characteristic (step S11 in FIG. 3).

The image information of the banknote Q read and generated by the optical sensor 332 is rotated with respect to the Y direction (vertical direction with respect to the X direction), as shown in FIG. It rotates by angle (theta). In addition, as shown to Fig.5A, the vertex on the upper left of banknote Q is made into point A.

The image processing unit 36 detects the coordinates of the point A and the rotation angle θ with respect to the Y direction from the image information of the banknote Q generated by the sensor unit 33. As shown in FIG. 5B, the image processing unit 36 rotates the image information based on the rotation angle θ, thereby making the image information of the banknote Q parallel to the X and Y directions. . In addition, the image processing unit 36 performs a moving process so that the coordinates of the point A are at the origin (coordinate 0 of the upper left corner).

In this way, the image information of the banknote Q is made parallel to the X direction and the Y direction, and the normalized image information of the banknote Q is obtained by image processing (normalization processing) that sets the point A to the origin O. (Step S12 of FIG. 3).

The normalized image information of the banknote Q thus obtained is held by the holding part 31 of the banknote processing apparatus 3. And this normalized image information is notified to the host computer 2 from the communication part 37 of the banknote processing apparatus 3 with the discrimination request | injection of the inserted banknote Q (step S13 of FIG. 3).

The communication part 22 of the host computer 2 receives the discrimination request of the banknote Q with this normalized image information from the banknote processing apparatus 3. Then, the discriminating unit 23 of the host computer 2 executes the following discriminating process on the state of the banknote Q based on the master template stored in the storing unit 21.

First, it discriminates about the gold type of banknote Q. Based on the normalized image information of the banknote Q, the master template suitable for characteristics, such as the dimension and an outline of a banknote Q, the shape of a printed pattern, and the shade, is specified. The paper type of banknote Q is discriminated as being the gold type which this suitable master template shows (step S14 of FIG. 3).

When the paper type of the banknote Q is not discriminated, subsequent processing in the host computer 2 is stopped, and the banknote processing apparatus 3 is notified that discrimination is impossible. In the banknote processing apparatus 3 in which the discrimination impossibility was notified, this banknote Q is returned from a banknote insertion port 3c to a user.

Next, the damaged state of banknote Q is discriminated. By comparing the specific master template with the normalized image information of the banknote Q, the total area of the defect portion is specified from the number of defect portions such as folding, holes, breakage, etc. of the outline of the banknote Q, and the area of each defect portion. The damage state (damage amount) of (Q) is discriminated (step S15 of FIG. 3).

In the case where the discriminated damage amount is equal to or greater than the predetermined amount or the damage amount cannot be discriminated, subsequent processing in the host computer 2 is stopped, and the bill processing apparatus indicates that the damage amount is equal to or greater than the predetermined amount or not discriminatable. 3) Notify. In the banknote processing apparatus 3 which received this notification, this banknote Q is returned to a user from the banknote slot 3c.

Next, the authenticity of the banknote Q is discriminated. The authenticity of the banknote Q is discriminated by comparing the specific master template with the normalized image information of the banknote Q (step S16 in FIG. 3).

If the normalized image information and the master template do not match, the subsequent processing in the host computer 2 is stopped, and the bill processing apparatus 3 is notified that the master template does not match. In the banknote processing apparatus 3 which received this notification, this banknote Q is returned to a user from the banknote slot 3c.

Finally, the conveyance state of banknote Q is discriminated. The specific master template is compared with the normalized image information of the banknote Q, and the conveyance state of overlapping conveyance, inclination, etc. of the banknote Q is discriminated from the appearance, thickness, etc. of the banknote Q (step S17 of FIG. 3). ).

When the banknote Q is discriminated as being conveyed in an abnormal state such as overlapping conveyance or inclination, or when the conveying state cannot be discriminated, it is conveyed in an abnormal state or that it cannot be discriminated. The bill processing apparatus 3 is notified. In the banknote processing apparatus 3 which received this notification, this banknote Q is returned to a user from the banknote slot 3c.

When the differentiation process of the above steps S14-S17 is complete | finished, the banknote processing apparatus 3 of the host computer 2 notifies the banknote processing apparatus 3 of the discrimination result (gold paper type, true right, little damage, normal conveyance) of the banknote Q. do. The banknote processing apparatus 3 conveys banknote Q to the stacker of the corresponding paper type according to this discrimination result.

In this way, the gold type master template of a banknote is stored in the host computer 2 communicatively connected to the banknote processing apparatus 3, and the banknote processing apparatus 3 is stored in the host computer 2 based on the master template. The state of the banknote Q put into it is discriminated.

Therefore, when updating is necessary for this master template, it is only necessary to update the master template stored in the host computer 2. For this reason, the update work with respect to each banknote processing apparatus 3 arrange | positioned in various places becomes unnecessary, and management and update work of a master template become easy.

In addition, since the latest master template is always stored in the host computer 2, it is possible to prevent differentiation of the bills Q by using the old master template by mistake.

In the above case, the case where the master template of true power was used was demonstrated. Hereinafter, the case where the master template of the upper right is used is demonstrated as an example.

≪ Example 1 >

It demonstrates again, referring FIG. 3 and FIG.

When the renewal of the master template is urgently needed in order to prevent the use of the check in the banknote processing apparatus 3, the host number of the check is host as a feature of the check. It is newly added and updated to the master template of the storage unit 21 of the computer 2.

In addition, an instrument number is assigned as the number inherent to each banknote in the position of Q1 and Q2 of banknote Q shown in FIG. Note that, besides the instrument number, for example, a so-called watermark is a feature of the banknote Q. The watermark is produced at the Q3 position of the banknote Q shown in Fig. 4, and is an image or shape which is distinguished by making the position of Q3 brighter than the surroundings.

When the banknote Q is put into the banknote processing apparatus 3 after the updating of the master template in this way, in step S11 of FIG. 3, in addition to the optical sensor 332, for example, the sensor unit 33 to which a character sensor is added, is added. By this, the instrument number of the banknote Q is also read.

After the predetermined process of steps S12-S15 of FIG. 3, the master number of the master ticket of the master template and the bank number Q of the banknote Q are compared.

As a result of the check, if there is no coincidence, since the banknote Q is not a wound, the usual discrimination process is performed.

On the other hand, in the case of a match, the subsequent processing in the host computer 2 is stopped, and the bill processing apparatus 3 is notified that the master template matches the master template. At the same time, it is also possible to notify the system administrator or the like who manages the entire banknote discrimination system 1. Moreover, the banknote processing apparatus 3 which received this notification does not return this banknote Q to a user, but is accommodated in the predetermined stacker inside the banknote processing apparatus 3.

In this way, in order to prevent the use of the check in the banknote processing apparatus 3 because the check is newly released, only the master template stored in the host computer 2 is updated even if the update of the master template is urgently needed. By doing so, it is possible to respond quickly and reliably.

Next, the image information of the banknote Q read and produced by the optical sensor 332 is made to be parallel with respect to the X direction and the Y direction similarly to step S12 of FIG. 3, and the image which makes the point A the origin O By the processing (normalization processing), normalized image information of the banknote Q can be obtained (step S22 in FIG. 7).

Next, the discrimination part 39 of the banknote processing apparatus 13 uses the master template hold | maintained by the holding | maintenance part 31, and the normalization image information of the banknote Q, The following discrimination with respect to the state of banknote Q is carried out. Run the process. In addition, steps S23 to S26 of the following discrimination processing correspond to steps S14 to S17 in FIG. 3, respectively.

First, it discriminates about the gold type of banknote Q. Based on the normalized image information of the banknote Q, the master template suitable for characteristics, such as the dimension and an outline of a banknote Q, the shape of a printed pattern, and the shade, is specified. The paper type of banknote Q is discriminated as being the gold type which this suitable master template shows (step S23 of FIG. 7).

When the paper type of the banknote Q is not discriminated, subsequent processing in the banknote processing apparatus 13 is stopped, and the banknote processing apparatus 13 returns this banknote Q to the user from the banknote inlet 3c. do.

Next, the damaged state of banknote Q is discriminated. By comparing the specific master template with the normalized image information of the banknote Q, the total area of the defect portion is specified from the number of defect portions such as folding, holes, breakage, etc. of the outline of the banknote Q, and the area of each defect portion. The damage state (damage amount) of (Q) is discriminated (step S24 of FIG. 7).

In the case where the discriminated damage amount is more than a predetermined amount or the damage amount cannot be discriminated, subsequent processing in the banknote processing apparatus 13 is stopped, and the banknote processing apparatus 13 passes the banknote Q into the banknote insertion slot. Return to the user from (3c).

Next, the authenticity of the banknote Q is discriminated. The authenticity of the banknote Q is discriminated by comparing the specific master template with the normalized image information of the banknote Q (step S25 in FIG. 7).

When the normalized image information and the master template do not match, subsequent processing in the banknote processing apparatus 13 is stopped, and the banknote processing apparatus 13 returns this banknote Q to the user from the banknote inlet 3c. do.

Finally, the conveyance state of banknote Q is discriminated. The specific master template is compared with the normalized image information of the banknote Q, and the conveyance state of overlapping conveyance, inclination, etc. of the banknote Q is discriminated from the appearance, thickness, etc. of the banknote Q (step S26 of FIG. 7). ).

When the banknote Q discriminates that the banknote Q is being conveyed in an abnormal state such as overlapping conveyance or inclination, or when the conveying state cannot be discriminated, the banknote processing apparatus 13 selects the banknote Q as a bill inserting hole ( Return to the user from 3c).

When the differentiation process of the above steps S23-S26 is complete | finished, the banknote processing apparatus 13 transfers banknote Q to the corresponding paper type stacker according to the discrimination result (gold paper type, true book, less damage, normal conveyance) of banknote Q. Return.

As described above, when storing the master template for each kind of banknote in the host computer 12 connected to the banknote processing apparatus 13 so as to be communicable, and discriminating the banknote Q in the banknote processing apparatus 13, the host computer ( The master template was transmitted to the banknote processing apparatus 13 from 12, and the banknote Q state was discriminated by the banknote processing apparatus 13.

Therefore, when the master template needs to be updated, it is only necessary to update the master template stored in the host computer 12. For this reason, the update work with respect to each banknote processing apparatus 13 arrange | positioned in various places becomes unnecessary, and management and update work of a master template become easy.

In addition, since the latest master template is always stored in the host computer 12, it is possible to prevent differentiation of the banknote Q by using an old master template by mistake.

In addition, in the above, the case where the banknote processing apparatus 13 performs the step A which receives a master template from the host computer 12 before step S21 was demonstrated. This step A may be any time as long as the timing before step S23 is executed. In order to execute this step A, for example, at the start of the operation of the banknote processing apparatus 13 by the user, the timing such as after the end of the image processing in step S22 can be considered.

In the above-mentioned case, the case where the master template of true power was used was demonstrated. Hereinafter, the case where the master template of the upper right is used is demonstrated as an example.

<Example 2>

This will be described again with reference to FIGS. 7 and 4.

First, as in the first embodiment, when the renewal of the master template is urgently necessary in order to make the examination unusable in the banknote processing apparatus 13, this examination is a feature of this examination. The new serial number is added to the master template of the storage unit 21 of the host computer 12 and updated.

After updating of the master template stored in the host computer 12, the banknotes introduced from the banknote inlet 3c of the banknote processing apparatus 13 are arranged inside the banknote processing apparatus 13 as shown in FIG. It is conveyed by the conveyance path 331.

When the conveyance of the banknote Q in the optical sensor 332 is detected by the position sensors 334a and 334b, this detection is notified to the CPU 38 from the banknote detector 32. By this notification, the CPU 38 notifies the host computer 12 of the master template transmission request via the communication unit 37.

When the transmission request is notified to the host computer 12, the transmission instructing section 25 transmits the master template of the highest authority stored in the storage section 21 to the banknote processing apparatus 13 through the communication section 22.

The transmitted master template is received by the communication unit 37 of the banknote processing apparatus 13 and transferred to the holding unit 31 by the CPU 38 to be held (step A in FIG. 7).

Subsequently, upon receiving an operation command from the CPU 38, the note number of the banknote Q is also read by the sensor unit 33 in which, for example, a character sensor is added to the optical sensor 332. Image information including the characteristics of the banknote Q is generated from the read characteristics (step S21 in FIG. 7).

Thereafter, the processes in steps S22 to S24 in FIG. 7 are similarly executed.

Next, the authenticity of the banknote Q is discriminated. The authenticity of the banknote Q is discriminated by comparing the master template with the renewed serial number of the bill and the banknote Q (the step S25 in FIG. 7).

As a result of the check, if there is no coincidence, since the banknote Q is not a ticket, the discrimination process proceeds at step S26.

On the other hand, in the case of coincidence, the subsequent processing in the banknote processing apparatus 13 is stopped, and the banknote processing apparatus 13 does not return this banknote Q to the user, but the predetermined inside of the banknote processing apparatus 3 is fixed. I receive it in the stacker of the. It is also possible to notify the system administrator or the like at the same time.

In this way, even when the renewal of the master template is urgently necessary in order to prevent the use of the survey in the banknote processing apparatus 3 as a result of the new check, only the master template stored in the host computer 12 is updated. By doing so, it is possible to respond quickly and reliably.

Also in the second embodiment, as in the case of the first embodiment, this step A may be any time as long as the timing before the step S23 is executed. In order to execute this step A, for example, at the start of the operation of the banknote processing apparatus 13 by the user, the timing such as after the end of the image processing in step S22 can be considered.

In addition, in Example 2, although the case of a serial number was demonstrated as an example of the characteristic of a police, it is not limited to a serial number as a characteristic of a police, and may be a watermark etc. similarly to Example 1.
