Description

  The present invention relates to a paper sheet processing apparatus that performs authenticity determination of paper sheets represented by banknotes, for example.

  2. Description of the Related Art Conventionally, banknote processing apparatuses having a function of determining authenticity of banknotes have been proposed in order to prevent the use of counterfeit banknotes for banknotes that are a type of paper sheet. This banknote processing apparatus reads data from a banknote using various reading means such as a magnetic sensor and an infrared sensor, and determines whether the read value of the read data falls within a predetermined threshold range. Authenticity is judged.

  Here, banknotes are distributed among people in various modes of use. For this reason, the banknotes that have been distributed are partially missing such as torn or cut. And a banknote with such a small missing range has the full value of a face value.

  Describing in detail the value of such missing banknotes, for example, according to the provisions of the Bank of Japan, even if there are partial missing banknotes, banknotes having an area of 2/3 or more have a full face value. Have value. In addition, Chinese banknotes have a full value in an area of 3/4 or more, and euro banknotes and US banknotes have a full value in an area of 1/2 or more.

  For this reason, even if the banknote has a partial omission, if the reading data of the other part is normal, the banknote processing device determines that the banknote read is a true banknote and permits its use. There is a need.

In view of this situation, there has been proposed a paper sheet inspection apparatus that can determine that a bill is a true bill even if a missing portion exists in the bill (see Patent Document 1). Even if a thickness abnormality is detected, this paper sheet inspection apparatus replaces the determination result that there is no abnormality if it can be determined that the thickness abnormality portion is a missing portion.
As a result, the paper sheet inspection apparatus does not determine that all of the banknotes are missing, but accepts them as true banknotes if they are slightly missing due to repeated use. ing.

  However, in recent years, when an attendant collects a banknote accepted from a user by a banknote processing apparatus typified by an automatic transaction apparatus such as an ATM, a banknote that has been subjected to artificial processing such as cutting is discovered. Things are happening. Such bills are processed into a state that cannot be considered in normal use, for example, a face value display portion is cut into a rectangle with a sharp knife such as a cutter knife.

  It is inferred that the intention of such processing is to analyze an important part used by the banknote processing apparatus for authenticity determination. And, it is considered that such an operation of inserting the processed banknote is intentionally performed by a person who attempts to counterfeit the banknote. If the operation of inserting the processed banknote is left unchecked, the counterfeit is determined to be true in the authenticity determination. There is a concern that banknotes will ramp up in the future.

  However, since the conventional paper sheet inspection apparatus treats a bill as a true bill even if a portion of the bill is missing, it is useful information for those who attempt to counterfeit bills when the above-described analysis is performed. There was a problem that could give.

Japanese Patent No. 2994137

  In view of the above-described problems, the present invention proposes a banknote processing apparatus that detects a processed paper sheet that has been artificially processed, and uses the processed paper sheet that leads to the rampage of high-precision counterfeit paper sheets. It aims at suppressing.

Output means for performing a predetermined output in some cases.

  In particular, even if the paper sheet is determined to be true by the true / false determination, the processed paper sheet is detected as long as it is a processed paper sheet that has been artificially processed.

  According to the present invention, it is possible to detect processed paper sheets that have been artificially processed.

An embodiment of the present invention will be described below with reference to the drawings.
First, the structure of the banknote processing apparatus 1 is demonstrated with the perspective view shown in FIG. 1, and explanatory drawing shown in FIG. In addition, in this embodiment, although the money changer is employ | adopted as the banknote processing apparatus 1, it can comprise by various apparatuses which process a banknote as paper sheets, such as not only this but ATM and a ticket vending machine. Moreover, in this embodiment, although it is set as the apparatus which processes a banknote, it can also comprise with the apparatus which processes other paper sheets, such as not only this but securities.

  The banknote handling apparatus 1 is installed in various stores such as banks, and as shown in FIG. 1, a coin outlet 2, a packaging coin outlet 3, a tray 4, a speaker 5, a card insertion slot 6, a statement slip outlet on the upper front surface. 7, a bill insertion / exit 8, and a touch monitor 9 (display for both touch input) as a notification unit and a display unit are provided, and a bill identification device 11 is provided inside the bill insertion / exit 8. .

  As shown in the partial enlarged plan view of FIG. 2 (A) and the partial enlarged side view of FIG. 2 (B), the banknote recognition device 11 is a line image sensor that is long in the width direction on the conveyance path 28 that conveys the banknote S. 27 is provided. The line image sensor 27 includes a line light source such as a fluorescent lamp or an LED array, and a sensor such as a CCD line image sensor or a PD array.

In this embodiment, the banknotes S are transported in the short direction, but may be transported in the longitudinal direction.

  With the above configuration, the banknote processing apparatus 1 executes banknote identification (denomination determination, authenticity determination, and processing presence / absence determination) of the banknotes by the banknote identification apparatus 11, and executes banknote exchange transactions based on the identification results. can do.

Next, the structure of the banknote processing apparatus 1 is demonstrated with the block diagram of the banknote processing apparatus 1 shown in FIG.
The CPU 16 as the control means controls each circuit device in accordance with a program stored in the ROM 17 and stores the control data in the RAM 18 so as to be readable. The RAM 18 also stores, as operation data, the payment transaction operation state and the like received during exchange.

The CPU 16 controls the banknote transport unit 10, the banknote recognition device 11, the operation unit 12, and the display unit 13 via the I / O interface 15.
The banknote transport unit 10 drives the transport path in accordance with a control signal from the CPU 16 and transports the banknotes to the banknote recognition device 11.
The banknote identification device 11 is an apparatus that executes authenticity determination and processing presence / absence determination after discriminating the denomination of the banknote, and details thereof will be described later.

The operation unit 12 allows the customer to input transaction data at the time of exchange from the touch monitor 9 (FIG. 1), accepts the customer's transaction use card from the card insertion slot 6 (FIG. 1), and further converts the banknote to be exchanged into the banknote. Accept from the entrance 8 (FIG. 1).
The display unit 13 displays and guides input items and operation guides on the touch monitor 9 (FIG. 1), an attached display (not shown), and an attendant panel (not shown). Here, the clerk panel allows an input operation by a clerk of arbitrary setting data for setting the operation mode.

  The photographing unit 14 serving as a photographing unit is a digital camera or a digital video camera having an image sensor such as a CCD or a CMOS, and photographs a user (a bill exercising person) who has inserted a bill. Although not shown in FIG. 1, the photographing unit 14 may be installed on the front panel of the banknote handling apparatus 1, and the photographing direction at the time of installation is a normal user standing in front of the banknote handling apparatus 1. The face position may be set.

  With the above configuration, the banknote handling apparatus 1 performs a denomination determination, authenticity determination, and processing presence / absence determination on the banknote received from the banknote entrance 8 to determine whether or not to permit the transaction, and to permit the transaction. A currency exchange process for exchanging money based on the transaction data input on the touch monitor 9 is executed.

Next, the structure of the banknote identification device 11 is demonstrated with the block diagram of the banknote identification device 11 shown in FIG.
The banknote recognition device 11 includes a CPU 21, a ROM 22, a RAM 23, a communication device 24, and an I / O driver 25, and various sensors (26, 27,...) Via the I / O driver 25. .

  The CPU 21 executes authenticity determination processing for matching the template data stored in the ROM 22 with the detection data temporarily stored in the RAM 23. As a result of the matching, if the similarity is within the appropriate range, it is determined to be a genuine note, and if it is outside the appropriate range, it is determined to be a false note. Furthermore, when it determines with a genuine note, the processing presence determination process which also determines the presence or absence of a process is also performed, and both determination results are transmitted to CPU16 (FIG. 2) of a banknote processing apparatus via the communication apparatus 24. FIG.

  The ROM 22 stores a program for operating the banknote recognition device 11, denomination determination image data, authenticity determination template data (waveform template data and the like), and a processing presence / absence determination module.

  The RAM 23 temporarily stores data detected by various sensors (26, 27,...). Here, the detected data refers to data such as detected waveform data and detected image data detected by various sensors (26, 27,...). The RAM 23 stores template data according to the necessity for adding template data.

The communication device 24 performs communication with the banknote processing device 1 (FIG. 2) that is a host device, and transmits the above-described determination result to the banknote processing device 1.
The I / O driver 25 is a driver for connecting various sensors (26, 27,...), And relays transmission / reception of signals between the various sensors and the CPU 21.

  The trigger sensor 26 detects that a banknote has been conveyed to the banknote recognition device 11 and transmits a detection signal to the CPU 21. In response to the detection signal, the CPU 21 starts identification processing.

The line image sensor 27 reads a banknote image to detect a waveform, and transmits this waveform data to the CPU 21 as detection data. This makes it possible to determine the authenticity of the banknote and the presence / absence of processing.
In addition, various sensors used for denomination determination and authenticity determination are provided, but details thereof are omitted.

  With the above configuration, the authenticity determination is performed by matching with the waveform data authenticity determination template data detected by the line image sensor 27, and the presence / absence of processing is determined by the processing presence determination module based on the waveform data. Can do.

Next, authenticity determination and processing presence / absence determination will be described.
5, FIG. 6, and FIG. 7 are explanatory diagrams for explaining the waveform data detected by the line image sensor 27 at the illustrated positions for the banknote S that has been intentionally processed.

  As shown in the plan view of FIG. 5 (A), the banknote S where the cut-out portion S1 is present at random locations or positions, or the artificial cut-out portion S1 (as shown in the plan view of FIG. 6 (A)). In this example, the banknote S where the monetary amount display portion is cut out along the characters) or another paper or the like is pasted on the cut-out (missed) portion as shown in the plan view of FIG. When the banknote S in which the pasting portion S3 is present is sensed by the line image sensor 27, a detection waveform K is obtained as shown in the waveform explanatory diagrams of FIGS. 5B, 6B, and 7B. Most of the detected waveform K is between the upper limit value and the lower limit value of the template waveform T, that is, within an appropriate range in which it is determined as a genuine note (a predetermined ratio or more). Therefore, in authenticity determination, it can be determined that it is a genuine note.

  However, since the abnormal waveforms K1 and K3 that are partly out of the appropriate range are seen, it can be determined that the banknote S is in a state of change such as torn, dirty, or processed. That is, for example, if the value at each position of the detected waveform K is a feature value, most of the feature values are true, and only some of the feature values (abnormal waveforms K1 and K3 portions) are false. A change determination can be made to determine that a change (including accidental and intentional) has occurred after the new ticket is issued. Since the abnormal waveform K1 is a cut-off portion, it is the same as the detected value when the banknote S is not present, and the abnormal waveform K3 is a portion that has been pasted and processed, so that any member is present. This is the detection value.

  When it is determined that there is a change in such a change determination, the presence / absence of artificial processing can be determined by the processing presence / absence determination module. Here, the artificial processing refers to processing that is artificially performed, such as cutting processing for cutting out a part of a bill, or partial material changing processing in which the cutting portion is closed with a member such as paper. The cutting process includes a punching process for making a hole in a part of a banknote and a notch process in which an end part of a paper sheet is partly cut out.

In the processing presence / absence determination by the processing presence / absence determination module, the presence / absence of processing can be determined by extracting the shape of the abnormal waveform K1 portion by image processing. For example, the boundary between the abnormal waveform K1 and the normal waveform K2 continues linearly over a certain range. If the boundary between the abnormal waveform K1 and the normal waveform K2 is beautifully curved and continues for a certain range or more, it is determined that the shape is not a naturally occurring shape but an artificially processed shape. The processing presence / absence determination is not limited to this, and may be executed by another method.
In this way, the authenticity determination and the processing presence / absence determination of the banknote S can be executed, and the processed banknote subjected to intentional processing can be detected.

Next, the operation | movement which CPU16 of the banknote processing apparatus 1 performs is demonstrated with the flowchart shown to FIG. 8, FIG. 9, and the screen image explanatory drawing shown in FIG.
The CPU 16 accepts that the banknote S is inserted from the banknote inlet / outlet 8 (step n1), conveys the accepted banknote S to the banknote recognition apparatus 11 by the banknote transport unit 10, and performs banknote identification processing on the banknote identification apparatus 11. Execute (step n2). In this bill recognition processing, the CPU 21 of the bill recognition device 11 performs the above-described authenticity determination, change determination, and processing presence / absence determination, and transmits these determination results to the CPU 16 by the communication device 24.

  If the determination result received from the banknote identification device 11 is not a genuine banknote (step n3: No), the CPU 16 executes a counterfeit bill suppression process (step n4) and ends the process. In the counterfeit bill suppression process, the inserted banknote S is returned as it is, and the user is notified that the banknote cannot be handled by display on the display unit 13 and voice output.

  When it determines with a genuine banknote (step n3: Yes), if this banknote S is not a processed banknote (step n5: No), transaction processing will be performed (step n6). This transaction process is a process of paying out banknotes or coins of a designated denomination according to the amount inserted, but the banknote processing apparatus 1 is another apparatus such as an ATM or a ticket machine. For example, an appropriate transaction process performed by the apparatus, such as a deposit process, a withdrawal process, or a sales process, may be executed.

  When it determines with a processed banknote (step n5: Yes), CPU16 image | photographs the user who is a banknote thrower by the imaging | photography part 14 (step n7). At this time, strobe light emission is executed as necessary so that the face of the user can be photographed as clearly as possible.

The CPU 16 executes a processing presence suppression process (step n8) and ends the process.
As shown in FIG. 9A, the CPU 16 holds the accepted banknote S in the device (step p1), and outputs an output with processing to the speaker 5 and the touch monitor 9, as shown in FIG. p2). As shown in the screen image diagram of FIG. 10 (A), this processed output is a bill M1 that requires confirmation because it is a banknote that needs to be confirmed, and a user that is a photographed image taken in step n7. The face image F is displayed and output on the touch monitor 9, and the above message is output by voice through the speaker 5. As a result, an unauthorized user who has inserted the processed banknote cannot collect the banknote S without calling an attendant. Therefore, since the unauthorized user bears the risk that the fraudulent act will be revealed by calling an attendant, and the banknote S cannot be collected, the subsequent processing of the processed banknote against such an unauthorized user Can be stopped. Further, by displaying the face image F, it is possible to give an anxiety that an unauthorized act has been recorded to an unauthorized user, and to effectively stop the subsequent processing of the banknote.

  The output with processing is not limited to this, and as shown in FIG. 10B, a warning message M2 indicating that the processing of the banknote touches the criminal law may be further added and output. In this case, not only the display output to the touch monitor 9 but also an audio output or light may be added to the warning. If comprised in this way, the person who does not have the criminal consciousness in the exercise of the processed banknote can have a criminal consciousness, and the subsequent execution of the processed banknote can be stopped.

  In addition, when a plurality of processed banknotes are inserted at once, or when a processed banknote is inserted by a plurality of transactions by the same user, a message for warning this user is displayed on the touch monitor 9 or the like. It may be configured to output. Thereby, the exercise of the processed banknote can be stopped.

  Further, as shown in FIG. 10C, the processing presence output is a bill that needs to be confirmed, so only the message M1 requesting the call of the attendant is output, and the display of the face image F of the user is performed. You may make it the structure which is not. Thereby, when it is detected that a banknote that happens to be cut in a straight line during distribution is a processed banknote, the face image F of the legitimate user is not displayed and the legitimate use Dissatisfaction can be prevented.

Further, it may be configured such that the photographing at step n7 is not executed and the photographing unit 14 is not provided. Thereby, cost reduction can be aimed at and it can avoid giving the sense of being monitored with a camera to a regular user.
The captured image captured in step n7 may be stored in the RAM 18. This makes it possible to specify the person who uses the processed banknotes after the fact.

  With the above operation, the CPU 16 of the banknote processing apparatus 1 can determine not only whether the accepted banknote S is authentic but also whether or not artificial processing has been performed on the true banknote. Therefore, it is possible to prevent a person who attempts to counterfeit bills by analyzing the mechanism of true / false determination from seeing a portion that becomes a point for determining the authenticity of bills.

  Thus, the banknote processing apparatus 1 is a touch which performs the output of a message, when the processed banknote is detected with the line image sensor 27 which detects the processed banknote by which the banknote S currently distribute | circulated in the market was made | formed artificially. Since the monitor 9 is provided, it is possible to suppress the use of processed banknotes that lead to the rampage of highly accurate counterfeit banknotes.

  Further, since the line image sensor 27 detects a paper sheet that has been partially cut out, it is processed even if it is a processed banknote that makes a true / false judgment. Can be reliably detected.

  In addition, since the touch monitor 9 notifies the message M1 that is unusable (confirmation is required), even if it is a processed banknote that is determined to be true in the authenticity determination, the user who has inserted the processed banknote Can be considered unusable. In other words, the authenticity judgment standard and the non-usable standard differ depending on the processed banknote, so the user who inserted the processed banknote cannot recognize whether or not the processed part is used for the authenticity determination. Counterfeit bills can be made difficult.

  Further, since the line image sensor 27 includes the photographing unit 14 for photographing the user when the processed banknote is detected, it is possible to grasp the face of the person who attempts the fraud by inserting the processed banknote, thereby preventing fraud. Can be useful.

  Moreover, since the touch monitor 9 displays and outputs a warning message M2 together with the photographed image photographed by the photographing unit 14, it is possible to hesitate to insert the processed banknote many times, Use can be suppressed.
