Description

  The present invention relates to a bankbook processing apparatus.

  The passbook processing device reads and writes information on the passbook medium inserted from the insertion slot, writes and reads the magnetic stripe, or drives the image sensor for each page previously assigned to the inserted passbook medium. By reading the media information such as the displayed page information such as the barcode and the number of printed lines of the already printed page by the printing unit that performs printing, the final printed line and the final printed page number of the medium can be determined. It has a function that can be grasped.

  If the inserted page of the passbook is different from the final printed page number, the page of the medium is turned, the next page is opened, the image sensor is driven again, and the information on the medium is read. Perform the operation. In addition, the passbook medium has a bar code and magnetic stripe with page information, although the display position varies depending on the operating organization, and media information is specified using both functions. .

  However, in a state where the medium information attached to the medium cannot be read, for example, the end of the medium is bent (hereinafter, the same state is abbreviated as the end bend) and the barcode cannot be read by the image sensor. When the medium is inserted, the final print line and the final print page of the medium cannot be grasped, and it may be impossible to specify the medium information. If the media information cannot be specified, the media is returned to the customer as an error.Therefore, the media cannot be read, for example, it has a function to detect a broken edge of the media. There are techniques for displaying guidance for prompting or correcting the state of a medium (for example, Patent Documents 1 and 2).

  However, in Patent Document 1, in order to detect an unreadable state of the medium information, it is necessary to match the medium information read from the magnetic stripe of the passbook medium with the medium information based on the image reading result. For this reason, since it is necessary to perform a magnetic stripe reading process and an image reading process until it is determined that the medium information cannot be read, it takes time to detect the unreadable state.

  Further, in Patent Document 2, by providing a border line on the back surface with respect to the print surface, the border line on the back surface reaches the end of the image with respect to the image read by the image sensor due to the end fold of the print surface. It is detected that the edge of the medium on the printing surface is broken. However, it is impossible to detect edge breakage with a bankbook medium that does not have a border line.

  An object of the present invention is to quickly detect a medium information unreadable state such as a broken edge in a means for reading medium information with an image sensor without adding a new function as in the above-mentioned patent document.

In order to solve the above-described problems and achieve the object, a passbook processing apparatus according to the present invention includes an image processing unit that reads image information of a passbook page, and a change in the image information caused by the thickness of the page. And a medium information determination unit that detects a page break.

  In addition, the passbook processing apparatus according to the present invention includes an image processing unit that reads image information of a page including identification information attached to a page of the passbook, and an edge break of the page based on a change in the configuration of the identification information. And a medium information determination unit to be detected.

  According to the present invention, it is possible to quickly detect an unreadable state of medium information such as edge breakage without adding a new function.

It is a figure of the state which turned up the page concerned one side ahead with respect to the medium in which edge breakage exists. FIG. 5 is a diagram showing a state in which one sheet of the next page is rolled with respect to a medium in which edge breakage exists. It is a figure showing the example of the flowchart of the passbook processing method in Example 2. FIG.

  Hereinafter, embodiments of the present invention will be described in detail. In the embodiments shown below, the passbook processing device according to the present invention is provided in various dedicated terminal devices in a system for exchanging data using a booklet-like medium such as a passbook with an automatic teller machine of a financial institution such as a bank. However, the present invention is not limited to this, but can be applied to a wide variety of devices that perform passbook processing.

  FIG. 1 shows a schematic diagram of the passbook processing apparatus 1. The passbook processing apparatus 1 includes, as main components, a medium insertion unit 3 for inserting the medium 2, a conveyance path 4 and a conveyance roller 5 for conveying the inserted medium 2, and an image reading mechanism unit for reading an image of the sucked medium 2. 6 and a control unit 7 for controlling driving of each unit. Further, an image sensor 61 is provided in the image reading mechanism section 6.

  In the control unit 7, there are a central processing unit 71 (hereinafter referred to as “CPU 71”), a conveyance driving unit 72, an image processing unit 73, a medium information determining unit 74, a page turning unit 75, a return processing unit 76, and a host host 8. The communication means 77 is provided with a storage area 78 for storing image data and storing analysis results of image data.

  FIG. 2A shows an example of a medium 2 such as a passbook used in a financial institution or the like. When the apparatus user inserts the medium 2 into the medium insertion section 3, the apparatus user inserts with an arbitrary page opened. Each page of the medium 2 is provided with a page mark 21 indicating page information in a specific pattern, and the image reading mechanism section 6 reads the page mark as image data to open the inhaled medium. The number of pages can be specified. However, the page mark 21 differs depending on the specifications of each medium issued by each financial institution and is not necessarily a uniform pattern. In the medium example of FIG. 2, the page mark is composed of a plurality of horizontal bars. However, the use of the page mark differs depending on the financial institution issuing the medium. As described above, there is a page mark 22 composed of a plurality of vertical bars, and there is a medium in which no page mark exists.

  When the user inserts the medium 2 into the medium insertion portion 3, the inhaled medium 2 is transported by the transport driving means 72 to a position where the image reading mechanism section 6 can read the page mark 21. As an image reading method, sensor scanning may be performed while the medium is being transported. When image reading is started by the image reading mechanism 6, as long as the page mark can be read normally as shown in FIGS. Page information can be acquired and transactions can be continued. However, as shown in FIGS. 3 (a) and 3 (b), when the page mark cannot be read normally from the image sensor 61 due to a broken edge of the page, the page information becomes illegal and the transaction An error occurs.

  Therefore, the image data obtained by reading the page by the image reading mechanism unit 6 is input to the image processing means 73 to analyze the image. This will be specifically described with reference to FIG.

  The image data is composed of the number of pixels decomposed at a resolution determined by the specifications of the image sensor 61. The data of each pixel may be color information or black and white information. In the case of black and white information, the data of each pixel is data expressed in a multi-level tone (hereinafter referred to as grayscale data). When extracting a page mark, black data of the page mark is obtained from the grayscale data. Is extracted and binarization is performed by setting a threshold value.

  FIG. 4 shows a gray scale data for the image data input to the image processing means 73 by the image reading mechanism 6 on the page where the page mark of FIG. An example is shown in which a white level with black as a minimum value and white as a maximum value is graphed for each row of scanning units. The horizontal bar code is identification information attached in a direction perpendicular to the page turning direction of the medium 2 such as a passbook. When the image processing unit 73 extracts page marks from the image data, the medium coordinate range determined as black data for each scanning row is dx_bar (n), and the black data coordinate range of each row is dx_bar (1) = 0. Let dx_bar (2) = b1, dx_bar (3) = c1, and dx_bar (4) = d1. In the pages before and after the folded page, if there is no edge break in the page of the medium, b1 = c1 = d1 should be satisfied, but if there is a edge break, the relationship of b1> c1> d1. It is represented by

  That is, in the pages before and after the folded page, the length of the horizontal bar code constituting the page mark 21 gradually decreases as the folded edge of the folded page becomes deeper. Therefore, the medium information determination unit 74 determines that edge breakage exists by extracting black data from the image data. Thus, in the present embodiment, by detecting and detecting changes and differences in the configuration of identification information (for example, the length of each of the black data) attached to the pages constituting the medium 2 such as a passbook, A page break is detected. Therefore, it is possible to detect a page break for a passbook with identification information such as a page mark only by adding a determination process using image information as described above.

  On the other hand, if the page is folded, the thickness of one page is different between the portion where the medium overlaps due to the edge break and the portion where the medium does not overlap, so the thickness of one page is white. Appears as a level difference. In addition, the definition of the thickness for one page may be an arbitrary fixed value, or the white level difference of the thickness for one page may be different for each passbook processing device due to variations in the performance of the image sensor such as resolution and resolution. Processing for determining a difference in white level in advance may be performed so as to set.

  Further, in the portion where the next page is visible due to the edge break of the page, the thickness of two pages appears as a difference in white level by comparing with the portion where the medium overlaps due to the edge break. In the example of FIG. 4, when the difference in white level for one page is set to th, the difference between the white level value of the medium coordinate x = 0 in the first row and the maximum value th (1) is 2th or more. Let the coordinate range be dx (1) = a. Also in the second line, as in the first line, the coordinate range in which the difference th (2) between the white level value and the maximum value of the medium coordinate x = 0 is 2th or more is dx (2) = b, the third line The coordinate range in which the difference th (3) between the white level value of the medium coordinate x = 0 and the maximum value is 2th or more is dx (3) = c, and the white level value of the medium coordinate x = 0 in the fourth row A coordinate range in which the difference between the maximum values th (4) is 2th or more is dx (4) = d. The medium information determination unit 74 has a relation of the coordinate ranges a, b, c, and d with respect to the image data input to the image processing unit 73 by the image reading mechanism 6 on the page where the edge break exists. If c <d, it is determined that edge breakage exists.

  In other words, in a page that is folded, the range of the overlapping portion is gradually widened as the folding becomes deeper, so that the medium information determination unit 74 determines that the edge is broken when the above relationship exists. It is determined that there is a fold. As described above, in this embodiment, the edge of a page is detected by detecting a change or difference in image information (for example, the range of the difference in white level) generated by the thickness of a page constituting the medium 2 such as a passbook. A break is detected. Therefore, it is possible to detect a page break even for a passbook having no identification information such as a page mark, simply by adding a determination process using image information as described above. Note that it is premised that the number of scan lines of image data is sufficiently large with respect to a range where there is an edge fold, and the determination is possible if the scan lines to be determined are two or more lines.

  FIG. 5 shows gray scale data for the image data input to the image processing means 73 by the image reading mechanism 6 on the page with the page mark of FIG. This is an example in which the white level is graphed for each row of scanning units, with black as the minimum value and white as the maximum value. The vertical bar code is identification information attached in a direction parallel to the page turning direction of the medium 2 such as a passbook. When the page mark is a vertical bar code, if the number of bar codes detected for each scan line is dx_bar_m (n), the value is either 0 or n on the pages before and after the broken page. It becomes. In the example of FIG. 5, if the number of vertical barcodes is 4 (n = 4), dx_bar_m (1) = 0, dx_bar_m (2) = 4, dx_bar_m (3) = 3, dx_bar_m (4) = 1. There is a value that does not match the book.

  Also, in the pages before and after the folded page, the length of the horizontal bar code constituting the page mark 21 is gradually increased as the folded edge of the folded page becomes deeper. For this reason, the medium information determination unit 74 can determine that the page is broken. As described above, in the case of the vertical bar code, as in the case of the horizontal bar code, the change of the configuration of identification information (for example, the length of each black data) attached to the page constituting the medium 2 such as a passbook By detecting the difference, the page break is detected.

  Therefore, as in the case shown in FIG. 4, it is possible to detect a page break for a passbook with identification information such as a page mark only by adding a determination process using image information as described above. it can. Note that the determination method based on the difference in white level can be the same method as in FIG.

  For media that do not have page marks such as barcodes, black data information for page marks and information on the number of barcodes do not exist. If it is a method, it can determine similarly. Further, in the above example, the case where the edge break of one page has been described, but the case where the edge break of two or more pages has occurred can be considered similarly. For example, the white level difference th is set to 3th, 4th, etc. according to the number of broken pages, and the medium information determination unit 74 determines which level the detected white level difference corresponds to. Thus, it is possible to calculate the number of pages that have been turned a plurality of pages at a time.

  As a series of processing procedures for making the above-described determination, FIG. 6 shows an example of a flowchart of the present embodiment. First, the medium insertion unit 3 detects the medium (step 101). The detected medium is conveyed to the mounting position of the image reading mechanism unit 6 (step 102). The image sensor 61 in the image reading mechanism unit 6 is activated to scan the medium 2 (step 103). The scanned image data is analyzed by the image processing means 73, and gray scale data is extracted (step 104). The medium information determination means 74 determines whether or not the medium information determination means medium mark position is broken from the extracted gray scale data (step 105). When the medium information determination unit 74 determines that there is no edge break (step 105; No), the page information is specified, and the process ends (step 106). If it is determined that there is an edge fold (step 105; Yes), the return processing means 76 performs a return process (step 107), and the user is given a “page broken in the passbook” as a medium reinsertion instruction 1. Please correct and insert your passbook again "(step 108).

  By the above processing, it is possible to detect a medium information unreadable state such as edge breakage only by analyzing image data without performing processing for reading information on the magnetic stripe, and to quickly return to the user. it can. In addition, by notifying the user that there is an edge break and correcting the media information unreadable state such as edge break by the user himself without going to the window, the waiting time of the user is consequently reduced. can do.

  Next, a description will be given of an embodiment in which the number of pages in which the edge breakage is detected is specified. In the present embodiment, the page turning means 75 shown in FIG. 1 is utilized. Note that the page turning means used in this embodiment is a means necessary for the original transaction processing, and is not a function newly added to the bankbook processing apparatus 1.

  The processing contents are the same as those in the first embodiment until the user inserts the medium 2 and determines whether or not there is edge breakage or the like. A process for specifying the number of existing pages is added.

  FIG. 7 shows a state in which one page with edge breakage is turned from the upper side to the lower side of the medium by the page turning means 75 from the state of the medium shown in FIG. By turning one page of the medium, the page mark of the previous page can be read. FIG. 8 shows a state in which the next page of the page in which the edge break is present is turned up from the lower side to the upper side by the page turning means 75 from the state of the medium in FIG. The page mark of the next page or the previous page can be read by turning one page of the medium in which the edge break is detected back and forth.

  From the above, by using the page turning means 75 provided as standard in the passbook processing apparatus, it is possible to identify the page where the edge breakage has occurred.

  FIG. 9 shows an example of a flowchart of this embodiment. The medium is detected by the medium insertion unit 3 (step 201). The detected medium is conveyed to the mounting position of the image reading mechanism 6 (step 202). The image sensor 61 in the image reading mechanism 6 is activated to scan the medium 2 (step 203). The image processing means 73 temporarily stores the image data of the medium 2 generated by scanning in the storage area 77, analyzes the image data, and extracts gray scale data (step 204). The medium information determination unit 74 determines whether there is any edge break from the extracted gray scale data (step 205). If the medium information determination unit 74 determines that there is no edge break, the medium information determination unit 74 specifies page information and ends the process (step 206). When it is determined that there is an edge break, the page turning means 75 turns the medium 2 by one page by the page turning process (step 207). Obtain the image data and read the page information from the page mark for the medium after it has been beaten, determine the previous page number or the next page number, calculate the difference between the two, and there is a break in the difference It is specified as the number of pages (step 208).

  Thereafter, the return processing means 76 performs return processing of the medium (step 209), and as a medium reinsertion instruction 2, to the user, “the page XX of the passbook is broken. Please make an announcement "(step 210). With the above processing, in addition to the effects of the first embodiment, it is possible to specify the page where the edge breakage of the medium has occurred. Therefore, the user is searched for the page where the edge breakage of the medium has occurred. There is no need.

  In the above example, the case where the page information is read from the page mark has been described. However, the page where the edge breakage has occurred may be specified using the determination method based on the difference in white level shown in the first embodiment. For example, when the medium information determination unit 74 counts the number of pages turned by the page turning unit 75, the relationship between the coordinate ranges in which the white level difference is 2th or more is the relationship shown in the first embodiment. It is determined whether or not there is. When the medium information determination unit 74 determines that such a relationship is established, it determines that there is a page break, and the return processing unit 76 adds 1 to the number of pages counted so far. The number may be notified to the user as a page where the edge of the medium is broken. By performing such processing, it is possible to identify the page where the edge breakage has occurred even in a medium such as a passbook that does not have a page mark such as a barcode, and notify the user. Also in this case, it is also possible to calculate the number of pages that have been turned over at a time by the same method as shown in the first embodiment and announce the number of pages.

  As described above, according to the present passbook processing apparatus, the reading of the magnetic stripe is not performed, the image data read from the medium by the image reading mechanism unit is utilized, and only the analysis of the pixel data is performed. Whether or not reading is possible can be determined. Further, if the next page can be read normally by performing page turning continuously, it is also possible to determine the number of the next page and to specify the number of pages in which the edge breakage has occurred. By making an announcement such as “The end of the page is bent. Please correct it and insert it again.”, The user can recover the medium reading error himself. This eliminates the need for guidance to the window and can reduce waiting time.
