Abstract

PROBLEM TO BE SOLVED: To generate an alarm against a convincing and an intentional correction of an end user by checking a tolerance of a correction input in the case a reading result is corrected, and to reduce a labor of a post-processing by a related organization caused by a post-correction. SOLUTION: In the case where a reading result of the document received by the device is corrected, a range for permitting a correction against the reading result is previously set and when the correction exceeds the set value, a limitation is imparted to the treatment after the event. A recognition result judged by a reading processing part 16 of a document processing part 6 is memorized in a memory part 21 of the document reading device 1 through a control part 17 and is indicated on an operation type display 2 and a correction is requested to a user. The tolerance is set at a tolerance set part 22. It is compared with the corrected content based on the result read by the device at a comparison judgment part 23 and it is judged whether or not the difference exceeds the previously set value. In the case where a correction is repeated, a counter 24 is added by one.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form reading device for making transactions such as transfer by an end user's operation by ATM or the like, and particularly when correcting information of a form received by the device by the end user. The present invention relates to a form reading device that determines acceptance conditions for the device according to a correction allowable range and a control method thereof.

[0002]

2. Description of the Related Art In recent years, devices for automatically processing forms have become widespread. As a specific example of a form reading device that receives a form from the outside and mechanically processes it, there is an automatic transaction device described in, for example, JP-A-57-134771.

This discloses various automatic transfer machines installed in a store of a financial institution, and the apparatus inserts a read form such as a transfer form into a form taking-in port by the end user's hand. It is conveyed by the form conveying means from the take-in port to a predetermined position in the device to be processed, and the processing information is read based on the input information by reading the written information on the form or the push button operation of the end user of the device. We perform mechanical processing such as printing and recording on a form, and collecting in a device.

Another example is JP-A-6-162253.
There is a character reading device described in the publication. This determines whether the total value S of the number of unrecognizable characters and the number of erroneously recognized characters exceeds a predetermined reference value N, and S is N
If it is larger, it is displayed on the display correction device to correct the character, and if S is N or less, it is corrected only when there is a correction intention, and finally the correction is made by the end user.

Since this type of device needs to perform the settlement process of the charges relating to the mechanical processing of the transfer money and the form in parallel, the end user's deposit card, passbook, etc. are used as the input form to pay the charge from the deposit account. It is a well-known form reader that has the requirements of an automatic machine such as deduction of fees, cash payment, withdrawal of change and passbook entry.

The forms handled by these automatic machines can be efficiently processed in a short time by collating with the information registered in the database in advance as the information that can be accepted by the upper processing section. However, when handling these with an automatic machine, in order to avoid the problem of "mishandling" in the unlikely event of misreading due to damage, stains or unclear printed characters on the receipt form,
It is customary to display the reading result on a display device or the like of the apparatus so that the end user can visually recognize it.

In this case, there is an attempt to check the validity of the apparatus or the host computer or to automatically correct it, but in the end, it is necessary for the end user to visually recognize and correct the recognition result. Become. However, especially when dealing with expensive money, if the correction input by the end user's assumption is accepted as it is, a trouble may occur in the post-processing. As an example, considering a case where cash is transferred as a recognition result, it is possible to intentionally correct the amount of money assumed by the end user even if the recognition result shows a correct one.

Conventionally, this correction input is processed as a regular input. If an erroneous correction is made in any of these, at a later date, the transferee will point out or the related organization will collect the deficient amount by checking the stated amount and deposit amount of the form collected from the device. The time and effort of post-processing cannot be ignored, and if mistakes are not noticed, they may be left as they are, resulting in a drop in service.

FIG. 7 is a perspective view showing an example of the structure of a conventional form reading device. In FIG. 7, reference numeral 1 denotes a form reader main body, which is connected to a host computer (not shown) or is configured to operate offline, and incorporates operation control units for various devices described below. . Reference numeral 2 is a tentacle input type operation display screen, and the end user performs an input operation according to a desired purpose according to the guidance of the transaction contents on this display screen. Reference numeral 3 is a money deposit / withdrawal port, and 4 is a banknote deposit / withdrawal port, and both accept and transfer coins / money deposits / changes for obtaining a desired purpose associated with the form processing.

Reference numeral 5 denotes a form take-in port, and the form received from the take-in port is drawn into a built-in form processing unit 6 for processing. Reference numeral 7 is a deposit / withdrawal card insertion / ejection slot, and 8 is a passbook insertion / ejection slot, which is used for confirmation of the person involved in the form processing and passbook entry processing. Reference numeral 9 is a statement outlet, which prints out the details of the transaction using the built-in statement issuing machine 25
The statement is discharged from.

FIG. 8 is a detailed block diagram of the form processing unit in FIG. In FIG. 8, the form 10 inserted from the form take-in port 5 is detected by the sensor 11, and when a take-in process command is issued from the higher-level processing unit 18 to the apparatus, the transport rollers 12a to 12d and a motor for rotationally driving the carry rollers 12a to 12d. The form 10 is sandwiched between rollers 12A to 12D that face the conveying rollers by 13 and a drive belt 14 (not shown in part), is drawn in from the intake port 5, is conveyed under the detector 15, and is conveyed to the form 10. The image information detected above is sent to the read / read processing unit 16 and is recognized.

The detector 15 shown in FIG. 8 is an optical detector such as a line image sensor, and can optically read the print information and the like shown in FIG. The reading processing unit 16 performs information processing such as cutting out a character or the like at a specific place in the form information, and sends the cut out information to the upper processing unit 18 via the control unit 17.

The upper processing unit 18 determines whether or not to accept the form based on the processing information sent, and sends the confirmation result to the control unit 17. If the higher-level processing unit 18 determines that the form is acceptable according to the determination result, the control unit 1
By issuing a command to the control unit 7, the control unit 17 suctions and activates the motor 13, and the form is conveyed under the print head 19. At this time, the control unit 17 is based on the information instructed by the upper processing unit 18.
Through the print head 19 to perform desired printing on the form,
It is stored in the recovery unit 20 and a series of processing is completed.

The printing by the print head 19 is performed on the form 1.
0 indicates the case where additional information etc. is given to a specific part,
Although the record information such as the reception serial number and the reception time is printed, it may be omitted depending on the transaction business and is not always necessary. Note that when the upper processing unit 18 rejects the acceptance based on the determination result, or when the end user performs a cancel operation, the upper processing unit 18 or the control unit 17 issues a reverse rotation instruction to the motor 13, and the form 10 When the form 10 is passed back through the intake port 5 and the form 10 passes the form sensor 11, the operation of the motor 13 is stopped and the end user waits for the form removal.

[0017]

As described above, in the conventional method, when there is an error in the read result, the one corrected by the correction input is treated as the correct one. Since there is no guard against corrections, indirect damages including post-processing of related organizations due to correction errors cannot be ignored. In addition, there are cases in which mistakes are not noticed, and there is an inconvenience in which service is degraded.

Therefore, an object of the present invention is to solve such a conventional problem, and when correcting the reading result of a form received by the apparatus, a range in which the reading result is allowed to be corrected is set in advance, Providing a form reader and control method that can eliminate post-processing trouble and prevent service degradation by limiting the subsequent processing by catching the correction that exceeds the set value To do.

[0019]

In order to achieve the above object, according to the present invention, whether the difference exceeds the preset range as compared with the corrected contents based on the result read by the apparatus. It is to determine whether or not. That is,
The form reading device of the present invention is a reading device that reads and recognizes the description information of a received form and is a method that allows the end user to correct the recognition result, and recognizes it as a storage unit that stores the recognition result. It is characterized by including setting means for setting a correction range of information, and means for comparing the set value obtained from the setting means with the correction result. Further, the form reading control method of the present invention is such that, in the comparison means, when the correction result exceeds the set value of the allowable range, and the number of redoing operations of correction exceeds a preset specified value, a warning or accepted form is received. It is characterized by collecting or returning, or dealing with them in combination.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a configuration diagram of a main part of a form reader according to an embodiment of the present invention. The overall configuration of the apparatus and the form handling apparatus are the same as those of the conventional configuration described with reference to FIGS. FIG. 1 shows a main part of an apparatus according to the present invention. Reference numeral 1 is a form reading device, 6 is a form processing unit, and 2 is an operation type display. In the form processing unit 6, 17 is a control unit and 16 is a read damage unit. Further, 21 in the form reading device 1 is a storage unit for a recognition result by the reading processing unit 16,
22 is a permissible range setting unit for correction by the end user, 23
Is a comparison determination unit for comparing the correction value by the end user with the allowable range, and 24 is a counter for counting the number of corrections. The reading information of the form is read from the reading processing unit 16 to the control unit 17
The recognition result is stored in the storage unit 21 via the, and the recognition result is displayed on the display unit 2.

At the same time, based on the recognition result, a permissible range setting unit 22 for setting a permissible range for correction outputs a comparison value and sends it to the comparison / determination unit 23. Next, when the end user looks at the display 2 and inputs a desired correction from the operation type display 2, the correction result is sent to the comparison / determination unit 23 via the counter 24. Here, when the value is compared with the previous allowable range comparison value, and the correction exceeding the allowable range is performed, the counter 24 is counted up, and when the specified number of times is exceeded,
The subsequent operation of the device is limited.
Restrictions include returning the form, collecting it, displaying or ringing a warning, or a combination of these.

FIG. 2 is an operation flowchart of a form reading control method showing an embodiment of the present invention. When the form is inhaled through the intake port (S11), the device reads the information on the form.
(S12). After displaying the result on the display (S
13), the presence or absence of correction is requested (S14). Here, if the correction is not necessary, the presence or absence of cancellation is sought (S15), and if not, the confirmation key or the like is pressed (S16). on the other hand,
If there is a correction, after the correction input (S19), it is determined whether the correction content exceeds the allowable value (S21), and YE
In the case of S, the count value of the correction number N is incremented by one and the correction input is waited again (S23). If the correction content exceeds the permissible value, a warning "Please check again" will be issued by voice or screen display.

When the count value N exceeds a specified value (eg N ') (S22), it is returned (S24). When returning it, "it cannot be handled with that value"
Etc. and give a warning by voice or display. Next, the presence or absence of cancellation is requested (S15), and if not canceled, the display on the display is confirmed, and after waiting for the confirmation key to be pressed (S16), desired printing is performed (S17), and the printed form is printed. Is collected (S1
8). If canceled, (S15-Y) will be returned.
(S20). It should be noted that instead of returning it, it can also be collected. Once collected, it can be used as evidence at a later examination.

FIG. 5 is a table showing the setting of the correction range according to the embodiment of the present invention. Since FIG. 5 shows a case where the digit number check and the similarity degree check are combined to make a determination, the similarity degree will be described with reference to FIG. 6, so only the case of the digit number check will be described here. The correction range of whether or not the allowable value in FIG. 2 is exceeded (S21) will be described using only the digit number check in FIG. In FIG.
The allowable range setting unit 22 sets the number of read digits = the number of corrected digits as shown in FIG. 5 as the allowable range set value, for example.
As an example, if 10,000 yen is displayed as the reading recognition result,
In this apparatus, the setting unit 22 of FIG. 1 automatically sets the number of digits to 5 digits.

For example, if the end user tries to correct this to 1 yen as in item No. 1 in FIG. 5, the number of digits read becomes ≠ the number of digits after correction, and the comparison / determination unit 23 in FIG. 1 makes the determination in S21 in FIG. In the process, YES is determined as outside the correction range. Similarly, if the end user tries to correct this to 100 yen as in item No. 2, the number of digits read becomes ≠ the number of digits after correction, and the comparison determination unit 23 in FIG. Is configured to be YES. Note that S22
The specified value N'of indicates a limited number of corrections,
Since the possibility of erroneous processing is very large when correction is made with a different number of digits, in this case N ′ = 1 may be returned immediately. The prescribed value N'will be decided upon.

FIG. 6 shows another embodiment of the present invention and is a table diagram when the similarity is used as the correction allowable range. Another example of determining the correction range will be described with reference to FIG. This table shows recognition results in rows and correction results in columns. For example, if the recognition result is 3, it is highly likely that the recognition of the device is incorrect.
They are 3, 8, and 9. Similarly, if the recognition result is 6,
It is set to 5, 6, and 8 as the items that are likely to be erroneously recognized. The degree of these recognition errors is peculiar to this type of document reading device and can be set in advance. If the correction result is erroneous for a high similarity in this table, the similarity check in S21 becomes YES and the correction is requested again.

Now, as an example of the check in FIG. 5,
When the reading recognition result is displayed as 8,000 yen as in item No. 10, if the end user mistakenly corrects it to 1000 yen, 1 is low from the similarity of 8 as shown in FIG. The comparison determination unit 23 determines that the corrected 1 is other than the read character≈correction character similarity candidate, and S2 in FIG.
If the answer is 1 in YES, another correction is required, and the subsequent operation of the device is processed according to the operation flow of FIG.

It should be noted that 100 as shown in item Nos. 13 and 14 of FIG.
If it is displayed as 00 yen, the end user mistakenly sets this to 7
When corrected to 0000 yen or 40,000 yen, as shown in FIG. 6, since 7 and 4 are both high in similarity from the similarity of 1, both are judged as similarity candidates by the comparison determination unit 23 of FIG. If NO in S21 of FIG. 2, the vehicle will pass. That is, item number 1 in the similarity check of FIG.
Only 3 and 14 are NO. As is clear from such determination processing, if the recognition result and the similarity after correction are high, it is not possible to check with 100% accuracy, but if there are numerical values in multiple digits as in item numbers 15-18. Has
It is possible to check with a high degree of accuracy by comparing and judging each digit.

When it is determined that the correction range has been exceeded, in the case where the specified number of times N'is exceeded and the process is redone, a message such as "Please check the correction amount again" should be given along with the automatic return. It may be displayed on a voice guide or a display. It is also possible to prevent the erroneous correction by collecting the data in the device without returning it. Alternatively, it is possible to make it more effective by combining the voice, the display guide, and either the collection or the return depending on the situation. Furthermore, when the specified number of times N is redone, it is possible to collect or return depending on the number of times.

In FIG. 2, one of the checks of the number of digits of the amount of money or the similarity check of numerical values in S21 for judging whether or not the correction allowable value is exceeded is judged. For example, in the case of the table of FIG. 5, in the determination of only the number of digits check, it is determined that the item numbers 1 to 6 exceed the permissible value, YES is obtained in S21, and another correction can be requested. However, the item numbers 7 to 18 have the same number of digits, so that it cannot be checked although it is actually an erroneous correction. On the other hand, in the table of FIG. 5, in the determination of only the similarity check, it is determined that the item numbers 7 to 18 exceed the allowable value, the determination result in S21 is YES, and the correction can be requested again. However, for the item numbers 1 to 6, since there is only one numerical value and the same numerical value, erroneous correction cannot be checked.

FIG. 3 is an operation flowchart of a combined form reading control method showing another embodiment of the present invention.
In FIG. 3, as shown in FIG. 5, by performing both the number-of-digits check and the similarity check, check omission due to erroneous correction as described above in FIG. 2 is prevented. When the form is inhaled through the intake port (S31), the device reads the information on the form (S32). Then, after displaying the result on the display (S33), the presence or absence of correction is determined (S34). here,
If no correction is required, the presence or absence of cancellation is requested (S3).
5). If there is no cancellation, wait for pressing the confirmation key etc.
(S36). On the other hand, if there is a correction, after the correction input
(S39), it is determined whether or not the correction content exceeds the allowable value due to the number of digits mismatch (S41).
43). When the count value N exceeds a prescribed value (for example, N ') (S42), it is returned (S44).

Next, it is judged by the similarity check whether or not the correction contents exceed the allowable value (S45), and if YES, the count value of the correction number M is increased by one and the correction input is waited again ( S47). If NO, count value M
When exceeds a specified value (for example, M ') (S46), it is returned (S48). Next, the presence / absence of cancellation is sought (S35). If not canceled, the display on the display is confirmed, and after pressing the confirmation key (S36), desired printing is performed (S3).
7) The printed form is collected (S38). If canceled (S35-Y), it is returned (S40). In this case, as is apparent from FIG. 5, almost all erroneous corrections can be checked except item numbers 13 and 14.

FIG. 4 is an operation flowchart of a form reading control method showing another embodiment of the present invention. In the present embodiment, processing for determining the procedure for determining the specified value N'M 'of the number of corrections is shown. That is, here, it is determined whether the number of corrections is two or more, whether the correction is to be returned or collected once, or the like, depending on what percentage or more the identification result is. When the form is inhaled from the intake port (S51), the device reads the information on the form (S52). Then, after displaying the result on the display (S53), the presence or absence of correction is determined (S54). here,
If no correction is required, the presence or absence of cancellation is requested (S5).
5). If there is no cancellation, wait for pressing the confirmation key etc.
(S56).

On the other hand, if there is a correction, after the correction input (S63), it is determined whether the correction content exceeds the allowable value by the digit number mismatch or the similarity check (S6).
5) In the case of YES, the count value of the correction number N is incremented by one and the correction input is waited again (S61). When the count value N exceeds a specified value (for example, N'or M ') (S66), it is returned (S68). Next, the presence or absence of cancellation is sought (S55). If not canceled, the display on the display is confirmed, and after pressing the confirmation key (S56), desired printing is performed (S57), and the printed form is printed. Is collected (S5
8). If canceled (S64-Y), return
(S64).

After this, it is assumed that there is a result as to whether or not there was no erroneous correction with respect to the previous correction input. For example, it is assumed that the collected transaction value and the transaction value actually deposited or withdrawn are inspected every one to two to three days, and a result indicating whether or not the correction input is correct is issued. The cumulative total of the false recognition rates of the same device including the previous inspection result, that is, the cumulative rate A of the passing rates without checking the false correction is calculated (S5
9) and it is determined whether this is 1% or more (S6).
0) When it exceeds 1%, it is determined that there are many error corrections only for that device, and the specified value N '= set for that device.
1 is set (S61). In other words, if the correction allowable value is exceeded, it is set to return or collect once. On the other hand, when it is 1% or less, the device determines that the error correction rate is normal and sets an arbitrary value of N ′ = 2 or more (S
62). By doing so, it is possible to take measures such as limiting the number of corrections to only once, returning the form immediately, and calling attention to the end user, especially in the case of a device with a lot of erroneous corrections.

In the embodiment of the present invention, an example of the amount of money is given as the correction information, but the same logic can be used for other character information for which a correction allowable range can be set such as similarity check. It goes without saying that you can do it. Also,
In the present embodiment, the next operation of the device is limited by the number N of correction operations exceeding the allowable value, but the correction input is sequentially monitored,
A warning may be issued during the correction operation, and the present invention is not limited to the embodiment of the present invention.

[0037]

As described above, according to the present invention,
When correcting the read result, by checking the allowable range of correction input, it is possible to warn the end user's assumptions and intentional corrections, and reduce the trouble of post-processing of related organizations by post-correction. There is an effect that can be.
