Technical Field

The invention relates to a paper sheet handling apparatus and a setting method.

Background

In the paper sheet handling apparatus, denomination determination processing, counting processing, authenticity determination processing, orientation detection processing, defect classification processing, and the like of the banknotes are performed. The good/defective bill sorting process is a process of sorting bills into good-note bills that have no problem in distribution, defective-note bills that are returned to a central bank due to being damaged to such an extent that they are unsuitable for distribution, and the like. The damage to the banknotes includes various types such as stains, graffiti, stains, and damages.

In the good defect discrimination, the paper sheet handling apparatus measures a damage degree which is a numerical value indicating a degree of damage to the paper sheet, and compares the damage degree with a reference value to discriminate the paper sheet into a good bill, a defective bill, or the like.

Patent document 1 discloses a paper sheet handling apparatus capable of setting a good defect level, which is a reference value for determining whether or not a banknote is a defective bill. The paper sheet handling apparatus displays a health defect level setting screen including a current health defect level stored therein, and sets a health defect level according to an operation of a user on the health defect level setting screen.

Patent document 1: japanese patent laid-open publication No. 2013-69039

In order to set the reference value for determining whether or not a banknote is a defective banknote to an appropriate value using the technique described in patent document 1, for example, a banknote regarded as a defective banknote or a banknote regarded as a good banknote is put into a paper sheet handling apparatus, the degree of damage of the banknote is measured, and the reference value is adjusted to an appropriate value while comparing the degree of damage with the banknote. However, it is actually difficult to intuitively grasp the degree of damage to which the banknote is damaged. In particular, since there are a plurality of types of damage, it is difficult to intuitively grasp the correspondence between each type of damage and the reference value. Therefore, skill is required to set the reference value to an appropriate value.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[ example 1]

Fig. 1 is a perspective view showing an external appearance of a banknote sorter (sorter) according to embodiment 1 of the present invention, and fig. 2 is a view showing a structure of the banknote sorter shown in fig. 1. The banknote sorting machine 100 shown in fig. 1 and 2 is a paper sheet processing apparatus that performs reconciliation processing on banknotes as paper sheets and classifies the banknotes into any one of a plurality of categories based on the processing result of the reconciliation processing. The reconciliation process includes a perfect defect discriminating process of discriminating a banknote into a perfect banknote having no problem in circulation and a defective banknote having been damaged to an extent not suitable for circulation, according to the degree of damage of the banknote.

The banknote sorter 100 shown in fig. 1 and 2 includes a hopper (hopper) section 110, a discriminating section 120, a cassette (pocket)130, a reject cassette 140, a distribution door 150, and a display input section 160. There may be a plurality of cassettes 130 and reject cassettes 140. In fig. 2, there are 4 boxes 130 and two reject boxes 140. When the 4 cassettes 130 need to be distinguished, they are referred to as cassettes 130A to 130D, and when the two reject cassettes 140 need to be distinguished, they are referred to as reject cassettes 140A to 140B.

The hopper 110 is an input unit into which the banknotes S are input. The banknotes S put into the hopper portion 110 are fed out one by a banknote feeding portion 220 described later, and the fed-out banknotes S are sequentially conveyed by a banknote conveying portion 230 described later.

The differentiating section 120 acquires differentiating information for differentiating (differentiating) the banknotes S from the banknotes S conveyed from the hopper section 110. Specifically, the authentication unit 120 includes various sensors such as a visible light sensor for acquiring a reflected image and a transmitted image of the banknote S by visible light, and a reading sensor for acquiring invisible security information that cannot be confirmed by the naked eye, and acquires authentication information based on sensor information acquired by these sensors. The security information can be acquired using infrared light, ultraviolet light, magnetism, or the like.

The information for authentication includes a damage degree which is a numerical value indicating the degree of damage (damage) of the bill S. The damage of the bill S includes a plurality of items (types), and the degree of damage is acquired for each item. The greater the damage (i.e., the greater the deviation from the original state without damage), the greater the degree of damage. Examples of the items include holes, damages, stains, dirt, graffiti, and information damages. The information damage is information loss such as loss of magnetic information and the like, which does not exist in a place where security information should exist (a place where a damaged banknote does not exist), information addition such as addition of a fluorescent agent to a place where security information should not exist (a place where a damaged banknote does not exist), and the like.

The cassettes 130 and the reject cassettes 140 are storage sections that store the banknotes S conveyed from the hopper section 110. The cassette 130 stores the banknotes S corresponding to the sorting result of the differentiating section 120. The reject box 140 stores therein a reject ticket such as a banknote S for which the authentication information cannot be acquired by the authentication unit 120 and a banknote S for which the transport posture is poor and which cannot be put into the box 130.

The dispensing gate 150 is a device for dispensing the transported banknotes S to any one of the cassettes 130A to 130D and the reject cassettes 140A to 140B.

The display input unit 160 has a function as a display unit for displaying various information and a function as an input unit for receiving various information in response to an operation from a user using the banknote sorting machine 100.

Fig. 3 is a block diagram showing the configuration of the control system of the banknote sorting machine 100. In fig. 3, the discriminator 120, the distribution gate 150, the display input unit 160, the controller 200, the storage unit 210, the bill feeder 220, and the bill conveyor 230 are shown as a control system of the bill sorting machine 100. The display input unit 160 includes a display unit 161 that displays various information and an input unit 162 that receives various information in accordance with an operation from a user.

The control unit 200 is a control unit that controls each unit of the banknote sorting machine 100. The control Unit 200 is a processor such as a CPU (Central Processing Unit), and executes a program that defines the operation of the processor to perform various processes related to the control of each Unit of the banknote sorting machine 100. For example, the control unit 200 performs a sorting process of sorting the banknotes S into any one of a plurality of categories based on the information for authentication acquired by the authentication unit 120, and stores the banknotes S in any one of the cassettes 130A to 130D and the reject cassettes 140A to 140B based on the processing result of the sorting process using the distribution gate 150. The control unit 200 also performs processing for displaying information corresponding to the authentication information acquired by the authentication unit 120 on the display unit 161. The classification processing includes, for example, denomination determination processing, counting processing, authenticity determination processing, orientation detection processing, sound defect classification processing, and the like.

The storage unit 210 is configured by a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and stores a program that defines the operation of the control unit 200, control data for controlling each unit by the control unit 200, and the like. The control data includes, for example, assignment destination information indicating a reference value used to discriminate the banknotes S by the sorting process, a process result of the sorting process, and a relationship of the cassette 130 or the reject cassette 140 that houses the banknotes S, and the like.

The bill feeding unit 220 feeds out the bills S, which are inserted into the hopper unit 110 shown in fig. 1 and 2, one by one. The bill transport section 230 transports the bill S sent out by the bill sending-out section 220 to the cassette 130 or the reject cassette 140 through the differentiating section 120.

In the banknote sorting machine 100 described above, if the user inserts (loads) the banknotes S into the hopper unit 110, the banknotes S are separated one by the banknote feeding unit 220, fed out to the transport path T, and then transported to the differentiating unit 120 by the banknote transport unit 230. The authentication unit 120 acquires authentication information from the bill S and outputs the authentication information.

The control unit 200 performs a sorting process of sorting the banknotes S into any one of a plurality of categories based on the information for discrimination from the discriminating unit 120 and the reference value stored in the storage unit 210. The control unit 200 determines the cassette 130 or reject cassette 140 in which the banknotes S are stored based on the processing result of the sorting process and the assignment destination information stored in the storage unit 210, and controls the assignment gate 150 to store the banknotes S in the determined cassette 130 or reject cassette 140.

In the present embodiment, the discrimination information includes the degree of damage as a numerical value indicating the degree of damage of the bill S, and the control section 200 performs, as the sorting process, a sound defect sorting process of sorting the bill S based on the degree of damage.

In the good/defective discriminating process, the control section 200 compares the degree of damage with the reference value stored in the storage section 210, and discriminates the bill S as a good bill or a defective bill. For example, the control unit 200 determines the banknote S as a good-note banknote when the degree of damage is less than the reference value, and determines the banknote S as a defective-note banknote when the degree of damage is equal to or greater than the reference value. The control unit 200 distributes the banknotes S to any one of the cassettes 130A to 130D based on the sorting result and the distribution destination information stored in the storage unit 210. For example, when the destination information sets that the good-note banknotes are stored in the cassettes 130A and 130B and the defective-note banknotes are stored in the cassettes 130C and 130D, the control unit 200 allocates the banknotes S determined as the good-note banknotes to the cassettes 130A and 130B and allocates the banknotes S determined as the defective-note banknotes to the cassettes 130C and 130D.

Note that, in the good defect sorting process, the banknotes S may be sorted into 3 or more categories. For example, the control unit 200 may classify the banknotes S into defective note banknotes, good note banknotes, and ATM banknotes that are almost undamaged banknotes suitable for loading into an ATM (automated Teller Machine) or the like. In this case, the good note bills are bills less damaged than the defective note bills and larger damaged than the ATM bills, and the reference values include a 1 st reference value for distinguishing the defective note bills from the good note bills and a 2 nd reference value for distinguishing the good note bills from the ATM bills.

The reference value may be set for each applicable range indicating the banknote to which the reference value is applied. Examples of the applicable range include all currencies, currencies of specific currency (e.g., yen), currencies of specific denominations (currency types) (e.g., 1 ten thousand dollar bills), and currencies of specific series (e.g., E-note of 1 ten thousand dollar bill (series of 5 th 1 ten thousand dollar bill after the war issued in 2004)). In this case, the discriminating unit 120 acquires the type (currency, denomination, and series) of the bill S as the discrimination information based on the sensor information, and the control unit 200 performs the defect discriminating process based on the reference value corresponding to the type of the bill S included in the discrimination information.

When the discriminating unit 120 acquires the damage degree for each damage item, the control unit 200 obtains, for example, a total damage degree which is a comprehensive numerical value corresponding to the damage degree of each item, and sorts the banknotes S based on the total damage degree and the reference value. The total damage level is the sum or weighted sum of the damage levels, etc.

Hereinafter, a process of setting a reference value for the sound defect classification process will be described. Note that, in the following, it is assumed that the banknote S is classified into any one of 3 types, i.e., ATM banknote, good banknote, and defective banknote.

When the reference value for the sound defect classification processing is set, the control unit 200 shifts to a maintenance setting mode, which is a specific mode for setting the reference value. For example, if the input unit 162 accepts a shift request from the user to the maintenance setting mode, the control unit 200 shifts to the maintenance setting mode.

In the maintenance setting mode, if the banknotes S are inserted into the hopper section 110, the control section 200 transports the banknotes S using the banknote feeding section 220 and the banknote transport section 230, causes the discriminating section 120 to acquire a banknote image which is an image of the front and back surfaces of the banknotes S, and acquires the degree of damage to the banknotes S for each item from the banknote image. The banknote image may be a region damaged by the banknote S, and need not be the entire banknote S.

The control unit 200 displays a damage notification screen including the banknote image acquired by the discriminating unit 120 and damage information indicating the degree of damage acquired by the discriminating unit 120 on the display unit 161. At this time, when the damage of the bill S includes information damage related to invisible information, the control unit 200 performs a process of making the bill image recognizable according to the degree of damage of the information damage. Examples of the processing include synthesizing an image indicating a damage (e.g., a predetermined mark) to a damaged portion of the banknote image and changing the color of the damaged portion of the banknote image. In this case, the larger the degree of damage, the larger the image indicating damage, or the larger the region in which the color is changed. The damage information may indicate the degree of damage itself, or may indicate a value in which the degree of damage is normalized to a predetermined range (for example, 0 to 99).

Fig. 4 is a diagram showing an example of a damage notification screen. The damage notification screen 400 shown in fig. 4 includes a banknote image 401 on the front side of the banknote S, a banknote image 402 on the back side of the banknote S, and damage information 411 to 413. On the surface of the illustrated banknote S, stains (Stain) and Graffiti (Graffiti) are present, and the stains and Graffiti are represented as such as stains 451 and Graffiti 452 in the front banknote image 401. Further, there is a loss of Magnetic information (Magnetic loss) as a damage of information on the reverse side of the bill S, and visual information 453 visually showing the loss of Magnetic information is synthesized on the bill image 402 on the reverse side. In the example of the figure, the visual information 453 is a mark (explosion mark) that is larger as the degree of damage (degree of loss of magnetic information) is larger. Not limited to the loss of magnetic information, the same information as the visual information 453 is synthesized even when the loss or addition of infrared information and ultraviolet information occurs.

The damage information 411 to 413 correspond to any one of the damages (dirt 451, graffiti 452, and visual information 453) shown in the banknote images 401 and 402, respectively, and are displayed in the vicinity of the corresponding damage. The damage information 411 to 413 includes the damage degree of the corresponding damage and the maximum value of the damage degree. Here, the damage degrees indicated by the damage information 411 to 413 are normalized to values of 0 to 99.

After the damage notification screen is displayed, if the input unit 162 accepts an instruction to set the reference value, the control unit 200 sets the reference value in the storage unit 210 based on the damage information included in the damage notification screen.

Specifically, if the input unit 162 accepts a selection instruction to select any one of the items of damage included in the damage notification screen, the control unit 200 displays a setting screen for setting a reference value on the display unit 161. Then, if the input unit 162 accepts an instruction to determine the setting of the reference value, the control unit 200 sets the reference value in the storage unit 210 based on the damage information of the item selected by the selection instruction. The selection instruction and the determination instruction are included in the setting instruction.

Fig. 5 is a diagram showing an example of the setting screen. The setting screen 500 shown in fig. 5 is a setting screen in the case where dirt is selected as a damaged item in fig. 4, and includes a category selection button 501 and a range selection button 502.

The category selection button 501 is a button for selecting a category classified by a reference value, and includes an ATM button 511, a Fit button 512, and an Unfit button 513. The ATM button 511 is a button for sorting the banknotes S having a degree of damage or more indicated by the damage information into ATM banknotes, the Fit button 512 is a button for sorting the banknotes S having a degree of damage or more indicated by the damage information into good banknote banknotes, and the Unfit button 513 is a button for sorting the banknotes S having a degree of damage or more indicated by the damage information into defective banknote banknotes.

The range selection buttons 502 are buttons for determining the applicable range of the bills indicating the applicable reference value, and include a full-currency button 521, a corresponding-currency button 522, a corresponding-denomination button 523, and a corresponding-series button 524.

The all-pass button 521 is a button for setting a reference value suitable for bills related to all passes (yen, dollar, euro, and the like).

The corresponding currency button 522 is a button for setting a reference value suitable for currency of banknotes related to currency of banknotes S (banknotes S with acquired damage) input into the hopper unit 110 in the maintenance setting mode. When the button is selected, a reference value suitable for a banknote in the same currency as the currency of the inserted banknote is set. For example, in the case where the inserted banknotes are 1 ten thousand dollar banknotes in yen, the reference value is applied to all banknotes in yen (1 ten thousand dollar banknotes, and the like), and is not applied to banknotes related to other currency (U.S. dollars, and the like).

The corresponding denomination button 523 is a button for setting a reference value suitable for the banknotes relating to the denomination of the inserted banknotes. If the button is selected, a reference value suitable for a banknote of the same denomination as the denomination of the inserted banknote is set. For example, in the case where the inserted banknotes are 1 ten thousand dollar banknotes in yen, the reference value is applied only to 1 ten thousand dollar banknotes in yen, and is not applied to banknotes related to other denominations (thousand dollar banknotes and the like). Note that the banknotes of other denominations include banknotes of other currency (such as U.S. dollars).

The corresponding series button 524 is a button for adapting the reference value to the bill related to the series of inserted bills. If the button is selected, a reference value suitable for a bill of the same series as the series of inserted bills is set. For example, in the case of an E-note in which the inserted banknotes are 1 ten thousand yen banknotes in yen, the E-note is applicable only to 1 ten thousand yen banknotes in yen, and is not applicable to banknotes related to other series (D-note of 1 ten thousand yen banknotes, etc.) and other denominations.

When the category selection button 501 and the range selection button 502 are selected, the control unit 200 sets a reference value to the storage unit 210 using the selected contents as a determination instruction. For example, when the Unfit button 513 of the category selection button 501 and the all-pass button 521 of the range selection button 502 are selected, the control unit 200 sets a value for determining that the bill S having the damage degree "45" or more normalized to a value of 0 to 99 is a defective bill as the 1 st reference value for distinguishing the defective bill from the defective bill, which is common to all-pass. Thus, the damaged banknotes S having a damage degree of dirt or more of the inserted banknotes are classified as defective banknote banknotes.

The classification and the application range of the classification may be further subdivided than in the above examples. The reference value may be different depending on the case of setting for sorting bills such as a bank or a cash center. Note that the ATM button 511 may be omitted when the banknotes S having the damage degree smaller than the 2 nd reference value are classified as ATM banknotes.

[ example 2]

In embodiment 1, the damage degree indicated by the damage information included in the damage notification screen is reflected in the reference value as it is, but in this embodiment, it is an example in which a change value, i.e., a change damage degree, obtained by changing the damage degree indicated by the damage information included in the damage notification screen can be reflected in the reference value.

In the present embodiment, if the input unit 162 accepts a selection instruction to select any one of the items of damage included in the damage notification screen, the control unit 200 displays a change screen for changing the degree of damage indicated by the damage information included in the damage notification screen on the display unit 161. Then, if the input unit 162 receives a change instruction for changing the damage level, the control unit 200 obtains the changed damage level in which the damage level is changed in accordance with the change instruction, and displays the setting screen. The subsequent processing is the same as in example 1, but differs in that the control unit 200 sets the reference value based on the degree of damage being changed when setting the reference value.

Fig. 6 is a diagram showing an example of the change screen according to the present embodiment. The change screen 600 shown in fig. 6 is a change screen in the case where dirt is selected as a damaged item in fig. 4, and includes a change button 601, a category switch button 602, a screen switch button 603, and a reference image 604.

The change button 601 is a button for changing the damage level. Specifically, the change button 601 includes change buttons 611 to 616 for changing the degree of damage by instructing a change in the degree of appearance of damage.

Change button 611 is a button for not changing the size of dirt, change button 612 is a button for making the size (area) of dirt 2 times, change button 613 is a button for making the size of dirt half, change button 614 is a button for not changing the concentration of dirt, change button 615 is a button for making the concentration of dirt 2 times, and change button 616 is a button for making the concentration of dirt half.

The relationship between the degree of appearance of damage (for example, the size and concentration of stain) and the degree of damage represented by numerical values is not limited to being in direct proportion, and is often complicated. Therefore, in the example of fig. 6, the degree of damage can be intuitively changed by instructing the change of the degree of damage in appearance by the change buttons 611 to 616. Since the size and concentration of the dirt can be changed, any one of the change buttons 611 to 613 related to the size of the dirt and any one of the change buttons 614 to 616 related to the concentration of the dirt may be selected.

The category switching button 602 is a button for switching a category to be selected in the setting screen shown in fig. 5, and includes an above button 621 and a below button 622. The above button 621 is a button for classifying the banknotes S having a damage degree or more into a desired category (ATM banknotes, good banknote banknotes, or defective banknote banknotes) on the setting screen as in the category selection button 501 of fig. 5. The following button 622 is a button for classifying the banknotes S having a damage degree or less into a desired category on the setting screen.

The screen switching button 603 is a button for switching to a screen in which the degree of damage can be directly changed, instead of changing the degree of damage in appearance by the change button 601. When the numerical value set as the reference value can be clearly grasped, the screen may be switched by the button to directly change the degree of damage.

The reference image 604 is an image showing a damaged portion of the selected item among damaged portions of the banknote image included in the damage notification screen.

When the change button 601 is selected, the control unit 200 changes the damage level using the selected content as a change instruction. Specifically, the control unit 200 obtains, as the change damage degree, a damage degree corresponding to the changed apparent degree in which the degree of damage has been changed by the selected change button 601. For example, when the change buttons 612 and 615 are selected, the control unit 200 obtains the degree of damage when the size of the stain represented by the reference image 604 is 2 times and the density of the stain is 2 times as the change degree of damage.

In addition, the control unit 200 may display the changed damage degree. Further, the control section 200 may process the banknote image based on the changed damage degree. For example, the control unit 200 may process the banknote images 401 and 402 in the damage notification screen 400 shown in fig. 4, or may process the reference image 604 in the change screen 600 shown in fig. 6. As the processing, there is mentioned matching of the degree of appearance of the damaged portion in the banknote image with the degree of appearance after the change. For example, when the change buttons 612 and 615 are selected, the control unit 200 makes the size of the stain in the reference image 604 2 times and makes the density of the stain 2 times. In this case, if the input unit 162 receives a determination instruction for determining the extent of damage to be changed, the control unit 200 displays a setting screen. The input unit 162 may receive, as the instruction to determine, a case where the category switching button 602 is selected.

In the example of the figure, a button for changing the degree of the damaged appearance to "double" or "half" is provided, but more subtle changes may be possible. For example, a change button may be prepared so that the degree of the appearance of the damage can be changed by a predetermined ratio (for example, 10%) at a time.

As described above, the present invention includes the following matters.

A paper sheet handling apparatus according to an aspect of the present invention includes: an input unit 110 for inputting the banknotes S; a discriminating unit 120 for acquiring a numerical value indicating the degree of damage of the bill and a bill image in which an image of a damaged portion of the bill is reflected; and a control unit 200 for classifying the banknotes into any one of a plurality of categories based on the numerical value and the reference value. The control unit displays the banknote image and the numerical value in a specific mode, and sets the reference value based on the displayed numerical value if a setting instruction for setting the reference value is input.

With the above configuration, since the reference value for sorting the banknotes according to the degree of damage can be set while viewing the degree of damage in appearance and the numerical value, the reference value can be easily set to an appropriate value.

Furthermore, the identification part acquires a numerical value according to each type of damage; the control unit distinguishes bills based on the integrated numerical value and the reference value corresponding to each numerical value, and displays the numerical value for each type of damage in a specific mode. In this case, even when there are a plurality of types of damage, the correspondence between the damage of each type and the reference value can be intuitively grasped, and the reference value can be easily set to an appropriate value.

Further, among the types of damage, there is information damage as damage related to invisible information in the bill; the control unit processes and displays the banknote image based on the numerical value corresponding to the information damage. In this case, damage to invisible information such as security information can also be visually confirmed.

Further, the setting instruction includes a selection instruction to select one of the types of damage; the control unit sets a reference value based on a numerical value corresponding to the type selected by the selection instruction. In this case, since the type of damage for which the reference value is set can be selected, the reference value can be easily set to an appropriate value.

The setting instruction includes a change instruction for changing the displayed numerical value; the control unit sets the reference value based on a change value that is a value obtained by changing the displayed numerical value in accordance with a change instruction. In this case, the reference value can be appropriately set even if there is no damaged banknote S having a damage degree suitable for the set reference value.

Further, the setting instruction includes a determination instruction to determine the changed value; the control unit processes and displays the banknote image based on the change value, and sets a reference value based on the change value if a determination instruction is input. In this case, even when the numerical value is changed, since the damage according to the changed value can be visually confirmed, the reference value can be easily set to an appropriate value.

The embodiments of the present invention described above are illustrative for the description of the present invention, and the scope of the present invention is not limited to these embodiments. Those skilled in the art can implement the present invention in other various forms without departing from the scope of the present invention.
