Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form processing apparatus and a form processing method used in a financial institution such as a bank, and particularly to a form processing apparatus and a form processing method having a function of printing a line such as a passbook on a line-by-line basis. Regarding

[0002]

2. Description of the Related Art Conventionally, automatic teller machines (hereinafter simply referred to as ATM) are used in financial institutions such as banks. One of the units mounted on this ATM is a composite form processing unit that can receive and process different forms such as payment slips and passbooks.

In this composite form processing unit, for example, as shown in FIG. 14, the reading of the page mark 202 printed on the facing surface of the passbook 201, the detection of the final printed line, the print density and the print position are performed. In order to evaluate the printing state such as, the image of the partial area 203 of the spread surface of the passbook 201 is read.

Normally, as a scanner for reading this image, a scanner having an effective visual field of about 20 mm in the width direction (Y direction) of the form conveyance path is used, and the page mark of the passbook 201 is within this effective visual field. The mounting position of the scanner is determined so that 202 can pass through. With this scanner, the page mark 20 of the passbook 201
2. The image of the end of each printed line is read to recognize the page mark 202 and determine the final printed line.

[0005]

However, as shown in FIG.
As shown in, when the skew is generated in the passbook 201 in the previous entry, printing is performed obliquely with respect to the print line set in the passbook 201 (hereinafter referred to as “skew line printing”).
May occur and the printing may extend over multiple lines.
In such a case, skewed printing cannot be detected reliably from a partial image, so the line that has already been printed is judged to be the next leading blank line, and printing is performed there. There was a risk of double printing.

Further, as shown in FIG. 15, when printing is interrupted in the middle due to ink shortage or the like, the image of the printed line cannot be captured by the scanner, and as a result, the printed line is not printed. There was a problem that the line was printed as the next blank line, which again caused double printing.

The present invention has been made to solve the above problems, and a form processing apparatus capable of correctly determining a printed line on a form and preventing the occurrence of printing defects such as double printing and the like. The purpose is to provide a form processing method.

Therefore, according to the present invention, it is possible to detect the conveyance skew of the form with high accuracy. Further, in the case of oblique printing, an inclination appears in a part of the image of the entire surface to be printed of the form, so that there is an advantage that the conveyance skew can be detected separately from the oblique printing.

Further, the print state evaluation means is a mark provided at a position displaced from the center of the print surface of the form in the biaxial direction from the entire image of the print surface of the form read by the image reading means. May be detected, the direction of inserting the form may be determined based on the position of the detected mark, and the print state may be evaluated in consideration of the determined direction of the form.

Since the orientation of the entire read image also changes depending on the insertion direction of the form, the accuracy of the evaluation can be improved by optimizing the method and standard for evaluating the printing state according to the insertion direction of the form. it can. For example, in the case of obtaining a projection for evaluation, it is necessary to switch the projection axial direction according to the vertical and horizontal orientations of the form insertion.

On a surface to be printed such as a passbook, for example, a page mark for identifying a page is provided at a position displaced in the biaxial direction from the center of the spread surface of the passbook. The insertion direction of the passbook appears as a difference in the position of the page mark in the image of the entire print surface of the form obtained by the image reading means. Therefore, by locating such a mark, it is possible to accurately determine the insertion direction of the form.

According to another aspect of the present invention, there is provided a form processing apparatus which conveys a form having a surface to be printed on a line basis, and a surface to be printed of the form conveyed by the conveying means. Printing means for printing in line units, an image reading means for reading the entire image of the printed surface of the form conveyed by the conveying means, and an entire image of the printed surface of the form read by the image reading means Skew detection means for detecting the conveyance skew of the form based on the above.

Furthermore, a form processing method according to another aspect of the present invention comprises a conveying means for conveying a form having a surface to be printed on a line-by-line basis, and the form of the form conveyed by the conveying means. A printing means for printing on the surface to be printed in units of the lines and an image reading means for reading the image of the form conveyed by the conveying means are provided, and the image reading means is used to print the image on the surface to be printed of the form.

Further, page marks 55a and 55b for identifying the pages of the passbook are printed at fixed positions on the facing surfaces of the vertical passbook 52 and the horizontal passbook 53, respectively. The page marks 55a and 55b indicate individual pages with unique patterns.

Next, the flow of payment processing by the ATM 100 of this embodiment will be described. In the following description, the CPU 22 executes a program stored in a storage device such as the ROM 28 to perform various calculations, controls, and data processing.

The composite form processing unit 120 depending on the customer
When a payment slip (indicated by reference numeral 40 in FIG. 4) is inserted from the insertion slot 1 of the above, the transport rollers 3a and 3b of the intake unit 3 are driven, and the payment slip is automatically transferred to the inside of the present composite form processing unit 120. It is captured. The payment note taken in is conveyed so as to pass through the reading surface of the image reader 9, and at this time, the entire image of the payment note is read by the image reader 9. After this, the payment form passes through the printing unit 10 and is held in the temporary holding unit 17 secured in the vertical form conveyance path between the printing unit 10 and the form storage units 11a and 11b.

The image of the payment note read by the image reader 9 is stored in the image memory 26, and character recognition is performed on the image. As a result, the account number of the payee entered in the payment form as the character recognition result,
Transaction data such as the amount to be paid is obtained, and the presence or absence of characters in the necessary entry fields and the type of payment form are confirmed.

The data which is the character recognition result is the operation panel 1
It is displayed on the display 50 along with the image of the payment form, and the customer compares the displayed contents to check whether the recognition result is correct. If it is correct, the customer presses the confirmation key on the operation panel 150. When the confirmation key is pressed, the customer is instructed to insert a banknote into the banknote unit 130, a coin into the coin unit 140, and a card into the card unit 101 by a message by a screen or a voice, and the account of the payee is displayed. Transactions such as payment are made.

Here, the passbook (vertical passbook 52, horizontal passbook 5
3. In order to perform the settlement by any other kind of passbook 60), when the passbook is inserted from the insertion slot 1, the magnetic stripe of the passbook by the magnetic stripe read / write unit 5 (reference numerals 54a and 54b in FIG. 5) is displayed. 2) and the image of the entire spread surface of the passbook is read by the image reader 9.

If the information can be normally read from the magnetic stripe of the passbook, based on the read information such as the customer's account number, the last transaction date, the balance of the account, and the page number to which the new transaction content should be recorded. Transactions such as payment from the customer's account to the payee's account are performed.

On the other hand, the entire image of the spread surface of the passbook read by the image reader 9 is stored in the image memory 26 through the internal bus 29. From this form image, the CPU 22 extracts features such as the outline of the passbook, the binding, the positions of page marks (indicated by reference numerals 55a and 55b in FIG. 5), and determines the type of passbook from these features.

After the passbook type is determined, the image of the page mark at the position specified by the passbook type is cut out from the entire image of the spread face of the passbook, and the page number corresponding to the page mark is obtained by pattern matching. At this time, it is also possible to determine the vertical and horizontal orientations of the passbook based on the position of the page mark in the passbook image.

Next, the CPU 22 determines whether or not the page number, which is the recognition result of the page mark, matches the next entry page number read from the magnetic stripe of the passbook. The passbook is moved to the printing unit 10 when it is determined that the double-page spread is correct.

Further, the CPU 22 evaluates the printing state based on the whole image of the passbook and judges the blank line to be printed next. At this time, when the previous print is straddling a plurality of lines due to the oblique printing, this is detected, and the blank line to be printed next is determined so that double printing does not occur.
Also, even if the previous print was interrupted in the middle of the line due to ink shortage, etc., this line is judged as the last printed line, and the blank line to be printed next is selected so that double printing does not occur. to decide.

Next, the transaction result is printed (bookkeeping) on the next blank line determined in this way. After entry, passbook read / write by magnetic stripe read / write unit 5
It is returned to the write position, where the information of the magnetic stripe is rewritten to the latest contents, and then the insertion port 1 is inserted through the capture unit 3.
Will be returned to.

After the passbook is returned, the payment note is moved from the temporary holding section 17 to the printing position by the printing section 10, and the printing section 10 carries out necessary printing such as handling date and time, handling office and the like. Subsequently, the payment note is conveyed to the image reader 9, the image of the print at the specific portion is read by the image reader 9, and the quality of the print density is determined by the character recognition process, and the determination result is notified to the CPU 22. To be done. After that, the payment form is conveyed to the form storage units 11a and 11b and stored therein.

Next, details of the processing for evaluating the printing state based on the entire image of the passbook will be described. FIG. 6 shows a flowchart of this processing. As an example, consider the case of the horizontal passbook 53, but the same applies to the case of the vertical passbook 52.

As shown in FIG. 7, first, the entire image of the spread surface of the horizontal passbook 53 is read by the image reader 9. Here, the image reader 9 has an effective visual field 91 for the entire width of the conveyance path so that the image of the payment form 40 can be read. Therefore, it is possible to read the entire image of the spread surface of the horizontal passbook 53 with the image reader 9.

The format composed of ruled lines indicating a plurality of print lines and characters / symbols printed on the spread page of the horizontal passbook 53 is printed in a predetermined dropout color for the image reader 9. 9
So that it cannot be read as an image.

The image of the facing surface of the passbook 53 read by the image reader 9 in step 601 is pixel by pixel.
It is binarized by a predetermined threshold so that the value of the printed portion becomes "1" and the value of the non-printed portion becomes "0" (step 60).
2) It is stored in the image memory 26. Then, the Y-axis projection value of the binarized image stored in the image memory 26 is obtained (step 603). FIG. 8 shows an example of measuring the Y-axis projection value. The Y-axis projection value is obtained by calculating the number of pixels having a value of “1” on the line 81 of Y coordinate for each X coordinate.

Subsequently, a line whose projection value is "1" or more is detected (step 604), and it is checked whether or not the line continues for a predetermined value A or more (step 605). If the line is not continuous for a predetermined value A or more, the line (or continuous line) is a line (or continuous line) on which a projection value is generated due to factors unrelated to printing, such as dirt.
The line (or continuous line) is not targeted for the subsequent processing, and the next applicable line is detected through step 609.

Here, as shown in FIG. 8, the default value A may be determined based on, for example, the number of lines for printing one character. The number of lines for one printed character may be directly used as the default value A.

A continuous line having a projection value of "1" or more and a predetermined value A or more is continuous (Xa1, Xa2, Xa in FIG. 8).
..) is detected, the sum of the projection values of the individual continuous lines is calculated, and it is determined whether or not the sum is equal to or greater than the specified value B (step 60).
6). The prescribed value B may be set based on the minimum value of the total sum of Y-axis projection values for one print line. This is because the total sum of Y-axis projection values for one print line differs depending on the type of font used.

In this judgment, for the continuous line whose total projection value is less than the prescribed value B (there is no such line in the example of FIG. 8), it is the continuous line in which the projection value is generated due to factors unrelated to printing such as stains. Therefore, the continuous line is not processed thereafter, and the next corresponding line is detected through step 609. In the example of FIG. 8, Xa1, Xa2,
It is determined that the total sum of the projection values of the continuous line Xa3 is equal to or greater than the specified value B, and as a result, the individual continuous lines Xa1, Xa
It is determined that a2 and Xa3 are continuous lines for one printing line, respectively (step 607).

Next, it is judged whether or not the number of continuous lines for one printing line is equal to or larger than the predetermined value C (step 608). Here, the default value C is set to a value with which it is possible to determine that skewed printing has been performed across two or more lines. Oblique printing over two or more lines means, for example, printing in which one line of printing is out of the area of one line of the passbook 53 on the next line, or when printing on the next line is longer than the specified length. It is the printing of the protruding state. If the number of continuous lines for printing one line does not reach the predetermined value C, it is determined that the printing line for the continuous line is a line that is correctly printed in the area for one line of the passbook 53, and the processing is performed via step 609. Then, the corresponding line is detected.

If the number of continuous lines for printing one line is equal to or greater than the predetermined value C, the value N of the counter is set to "1". The above processing is repeated until the final line, and the value N of the counter is incremented each time a continuous line for one printing line having the number of lines equal to or greater than the predetermined value C is determined (step 61).
0).

When the value N of the counter reaches the specified value D (YES in step 611), the transport skew of the passbook 53 is determined (step 612), and the end of the evaluation of the projection value up to the final line is not waited. Then, the passbook 53 is returned to the user. For example, "2" is set as the predetermined value D. That is, in the case where a continuous line corresponding to one print line having the number of lines equal to or greater than the predetermined value C is determined, the passbook itself is conveyed obliquely (skew conveyance) as shown in FIG. However, unlike skewed printing in the case of skew feeding of a passbook, all the printed lines in a page are determined as skewed printed lines. On the other hand, skewed printing is often the case of only one line on a page. For this reason, if the number of skewed print lines determined is, for example, "2" or more, it is considered that the skew conveyance of the passbook has occurred, and the customer is returned and the passbook is reinserted. As a result, it is possible to prevent recurrence of the skew printing. Of course, a value of "3" or more may be used as the predetermined value D.

If the processing of all the lines is completed while the counter value N is "1", the oblique print is determined (step 61).
4) The control is performed so that the next printing is performed on the line next to the line used by the oblique printing. Throughout the processing of all the lines, in step 608, if a continuous line for printing one line whose number of lines is the predetermined value C or more is not detected, it is determined that neither skew printing nor passbook skew conveyance has occurred, and printing is completed. Controls printing to the next line.

Next, a modification of this embodiment will be shown. As a modification of the skew conveyance determination method of the passbook, as shown in FIG. 10, when it is determined that all the print lines in the page of the passbook are skew print lines (YE in step 1011).
S), the skew conveyance of the passbook is determined (step 101
2) In other cases, skew printing may be determined (step 1013). Here, S10 of FIG.
01-S1009 is common to S601-S609 of FIG. 6, and the description thereof is omitted.

Furthermore, instead of returning the passbook to the customer when skew conveyance is determined, the width-shifting mechanism 13 may perform the passbook alignment processing. After orientation
The entire image of the spread surface of the horizontal passbook 53 is read again by the image reader 9 and the above-mentioned processing is restarted.

As described above, according to the composite form processing unit 120, printing defects such as skew printing and skew conveyance of the form can be detected with high accuracy. As a result, double printing due to erroneous detection of a printed line as the leading blank line can be prevented, and skew printing due to printing in a skewed conveyance state can be prevented.

Further, the composite form processing unit 120
According to FIG. 11, even if the printing is interrupted in the middle of a line due to ink shortage or the like, this line can be determined as a printed line and double printing can be prevented. .

(Other Embodiments)

The function of detecting a page mark in the entire image of the spread surface of the passbook read by the image reader 9 and determining the insertion direction of the passbook based on the position of the detected page mark is described above. It may be added to the form processing unit 120.

In FIG. 12, 53 (a) is a horizontal passbook inserted in the correct orientation, 53 (a) is a horizontal passbook inserted in the wrong orientation, and 53 (c) is a state rotated 90 degrees to the right. Horizontal passbook inserted in, 53 (d) is 90 to the left
The horizontal passbooks inserted in a rotated state are shown.

As described above, the position of the page mark 55b in the passbook image read by the image reader 9 changes depending on the inserting direction of the horizontal passbook 53. Therefore, the insertion direction of the horizontal passbook 53 can be determined from the detected position of the page mark 55b. This also applies to other types of passbooks such as the vertical passbook 52.

The following control can be performed based on the determination result of the insertion direction of the passbook. For example, the passbooks 53 (b) (c) (d) inserted in the wrong orientation are controlled to be returned to the customer. Further, by changing the printing state evaluation method according to the direction of inserting the passbook, it is possible to evaluate and print the printing state as it is without returning the passbook to the customer.

FIG. 13 shows the procedure in this case. The passbook 53 read by the image reader 9 in step 1301.
After binarizing the image of the double-sided spread (step 130)
2) The position of the page mark 55b in the image is detected (step 1303), and the insertion direction of the passbook is determined based on the detection result (step 1304). Here, the description of the common parts with FIG. 6 is omitted.

As described above, the direction of inserting the passbook is
There are four types as shown in FIG. Passbook 53 here
If the orientations of (a) and (b) are determined, the Y-axis projection value is obtained (step 1305a), and if the orientations of the passbook 53 (c) and (d) are determined, the X-axis projection value is obtained ( Step 1305b). After that, the calculated Y-axis projection value or X
Using the axial projection value, the processes from step 1306 are performed in the same manner as in the above embodiment.

The method of determining the next leading blank line from the result of evaluating the printing state of the passbook is also changed according to the determined insertion direction of the passbook. For example, passbook 53
In the case of (b), contrary to the case of the passbook 53 (a) having the correct orientation, it is determined that the leading blank line exists on the transport direction side from the last printed line. Passbook 53 (c) and (d)
In the case of, it is determined that the leading blank line exists in one of the directions orthogonal to the transport direction from the last printed line. Further, it is possible to change the method of printing on the leading blank line of the determined passbook, or to change it according to the determined insertion direction of the passbook.

As described above, according to this embodiment, the printing state of the passbook can be evaluated with high accuracy regardless of the orientation in which the passbook is inserted, and printing defects such as skew printing can be obtained. Also, skew conveyance of the form can be detected with high accuracy. As a result, double printing due to erroneous detection of a printed line as the leading blank line can be prevented, and skew printing due to printing in a skewed conveyance state can be prevented. Therefore, the restrictions when inserting the passbook are alleviated, and the operability for the customer is improved.

The form processing apparatus of the present invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made without departing from the scope of the present invention.

As a method of evaluating the printing state based on the image of the entire surface to be printed of the form, the projection processing is used in the above embodiment, but as a result, printing defects such as oblique shadow printing and printing interruption can be measured. Any process may be used as long as it is a method.

In the above embodiment, the position of the page mark is detected from the image of the entire print surface of the form in order to detect the insertion direction of the form. Any target mark may be detected as long as it is a mark provided at a position displaced in the biaxial direction from the center. For example, it may be a character such as letters, numbers, or symbols, or a figure or image other than a mark.
