It is a figure which shows the processing flow of the processing operation example of the client server system in FIG. FIG. 3 is a diagram for explaining a method of realizing the processing flow in FIG. 2 alone. It is a figure for demonstrating the implementation system at the time of performing the implementation system of FIG. 3 by two or more. It is a figure which shows the example of an image of the contract as a fixed form document based on the Example of this invention, and the example of information corresponding to it (before correction). It is a figure which shows the example of an image of the contract as a fixed form document based on the Example of this invention, and the example of information (after correction) corresponding to it.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing an overall configuration of an embodiment of a client server system according to the present invention.

  The client server system according to the present embodiment includes a client PC 10 and a client PC 20, an AP server (Application Server) 30, and a DB server (DataBase Server) 40, as shown in FIG. The client PC 10 and the client PC 20 are connected to the AP server 30 and the DB server 40 on the in-house LAN. In the example of the figure, a case where two client PCs are included is shown as an example, but a larger number of client PCs may be included.

  The AP server is a server that has a function of accepting a request from a client PC and bridging it to the processing of a business system such as a DB (DataBase). The DB server has a database of business and searches from the client PC. It is a server that performs processing when a request for updating or updating is received and returns a processing result.

  The display device a11 and the display device b21 are display devices included in the client PC 10 and the client PC 20, respectively.

  The receiving means X50 and the receiving means Y60 in the AP server 30 are processing means by a daemon program corresponding to the client PC 10 and the client PC 20, respectively, and are connected to the magnetic disk device 70 on the DB server 40, respectively. It consists of

  The daemon program is not a program directly controlled by the user, but a program that operates in the background in a multitasking operating system such as UNIX (registered trademark).

In the figure, the control means 35 is a means for controlling the entire AP server 30, and the prefetch means X ₁ 80 and the prefetch means Y ₁ 90 are generated from the reception means X 50 and the reception means Y 60, respectively. This is means for pre-reading image data stored in the magnetic disk device 70 and downloading it to the client PCs 10 and 20. As will be described later, the magnetic disk device 70 includes, for example, an image itself including a standard document such as a contract and a variable character area (a personal information description area handwritten such as a contractor's name and address) in the image. A pair of information that is not necessarily accurate and is read and recognized by OCR or the like is stored.

The present invention uses the prefetching means X ₁ 80 generated from the receiving means X50 by the daemon program or the prefetching means Y ₁ 90 generated from the receiving means Y60 by the daemon program, and prefetches the image data of the DB server in the background. Thus, the response of the screen transition of the display device of the client PC is improved by downloading.

  FIG. 2 is a diagram illustrating a processing flow of the prefetching method when the display device of the client PC performs screen transition in the client server system configuration described in FIG.

Display a client PC 10 (client PC20 as well) is for displaying a pair of images A and information _{A 1} to 1 screen, when issuing the request to the receiving means from the client PC 10 (client PC20) (120) The receiving unit obtains image data (a pair of image A and information A ₁ (information A ₁ is information that is not necessarily accurate read from the variable character portion of the image A, for example, by OCR)) from the DB server 40. (130).

The acquired image data (a pair of the image A and the information A ₁ ) is responded to the client PC 10 (or the client PC 20), and the image data (a pair of the image A and the information A ₁ ) is displayed on the display device a110. .

The present invention predicts that the next image data (the image B and the information B ₁ corresponding to the image B will be read at the time when the image A and the information A ₁ are read, generates a prefetch means from the receiving means (140), The image B is prefetched (150) and downloaded to the client PC 10 (or client PC 20) (160) The download destination is a download folder in the standby memory of the client PC 10 (or client PC 20).

Incidentally, performed only for large image B of the data size to prefetching is not performed for small information B ₁ data size. The information B ₁ has an extremely small data size compared to the image B and can be downloaded instantaneously. Therefore, the information B ₁ may be downloaded at the time of actual use.

  When the screen of the display device a of the client PC is changed (210), the display device a tries to acquire the image B, but since the prefetched image B already exists in the download folder of the standby memory, The image B is read from the download folder (170).

The same applies to the image C and the information C _{1. When} the image B and the information B ₁ are read, the next image data (the image C and the information C ₁ corresponding to the image C are expected to be read and the image C is pre-read. (180), download to the client PC 10 (or client PC 20) (190) The download destination is the download folder in the standby memory of the client PC 10 (or client PC 20).

  When the screen of the display device a of the client PC is changed (220), the display device a tries to acquire the image C, but the prefetched image C already exists in the download folder of the standby memory. The image C is read from the download folder (200).

As described above, images B, C,... That have a large data size, that is, a large amount of information and takes a long time to download, are pre-read and stored in the download folder in the standby memory in advance, and the screen transitions. Reads out the images B, C,... From the download folder in the standby memory and displays them on the display device a. At this time, information B ₁ , C ₁ ... Corresponding to the images B, C,... Is read from the magnetic disk device 70 of the DB server 40 and displayed on the display device a as a pair with the image B. As described above, since the information B ₁ , C ₁ ... Has a small data size and can be instantaneously read from the DB server 40, the image B and the information B1 are displayed almost simultaneously.

  In the present invention, at the time of screen transition, since an image having a large data size is prefetched in the background and downloaded and stored in the client PC in advance, the screen transition time is changed. Thus, it is not necessary to newly download from the DB server 40 via the network, and as a result, the response of the screen transition can be greatly improved.

  FIG. 3 is a diagram showing, in time series, the timing at which an image and information corresponding to the image are displayed on the display device a of the client PC 01 and the timing at which the image and information corresponding to the image are read.

The display device a of the client PC 01 first downloads the image A and the information A ₁ and displays them in pairs (display data A ₀ = image A + information A ₁ ).

User (operator) refers to the image A and information A ₁ displayed in pairs on a display device a client PC01, while viewing the image A, the variable character area of the image A (the contractor name, address, etc. If personal information description region) in the corresponding information a ₁ data is not correct (if the corresponding content inconsistent image a) is modified to match the content of the image a (in the figure "information a ₁ In process: 04 ").

  Meanwhile, as described above, the image B that has been downloaded behind the scenes by the prefetching means and stored in the download folder of the standby memory 03 is read (“image B is read: 05” in the figure).

Correction processing of information A ₁ is to be reflected in the information A ₁ that is stored in the magnetic disk device 70 of the DB server 40 when finished.

Information B ₁ corresponding to the image B read from the download folder in the standby memory 03 is read from the magnetic disk device 70 of the DB server 40 and displayed on the display device a in a pair with the image B (display data B ₀ = image B +). information _B 1).

In this example, the user (operator) refers to the image B and the information B ₁ displayed in a pair on the display device a of the client PC 01, and while viewing the image B, the variable character area (contractor) of the image B name, if the data of the personal information description region) corresponding to the information B ₁ such as an address is not correct modified to match the content of the image B (in the figure "processing of information B _1: 06 ').

  Meanwhile, as described above, the image C that has been downloaded behind the scenes by the prefetching means and stored in the download folder of the standby memory 03 is read out ("Read image C: 07" in the figure). ).

When the correction process of the information B ₁ is completed, the information B ₁ is reflected in the information B ₁ stored in the magnetic disk device 70 of the DB server 40.

Information C ₁ corresponding to the image C read from the download folder in the standby memory 03 is read from the magnetic disk device 70 of the DB server 40 and displayed on the display device a in a pair with the image C (display data C ₀ = image C +). information _C 1).

User (operator) refers to the image C and the information C ₁ displayed in pairs on a display device a client PC01, while viewing the image C, the variable character region of the image C (the contractor name, address, etc. If information C ₁ of data corresponding to the personal information description region) is not correct is modified to match the content of the image C.

  The above-described processing is similarly performed on image data (image D-information D1, image E-information E1,...) Such as a contract that the user intends to continuously process.

  In FIG. 3 described above, the implementation method in the case of reading in time series on the display device a of a single client PC has been described, but in FIG. 4 described below, the case of reading in time series on the display devices of a plurality of client PCs An implementation method will be described.

  When a plurality of users perform processing separately using a plurality of client PCs, prefetched images may overlap due to the work amount of each user and the processing ability of each user. FIG. 4 is a diagram showing the processing pattern in such a case in time series.

The processing flow shown in the upper part of FIG. 4 is almost the same as that described with reference to FIG. 3, but in the case of FIG. 4, the client PC 01 downloads the image B that has been downloaded in advance during the processing of the information A _1. Is read from the download folder of the standby memory 03. At this timing, the image C is downloaded and stored in the download folder of the standby memory 03.

The client PC 09 performs similar processing on the images D, C, E, and the like. The figure shows a case where the image C is processed before the image E, and the display device b of the client PC 09 first downloads the image D and the information D ₁ and displays them in pairs (display data D ₀ = image). D + information D ₁ )).

In this example, the user (operator) refers to the image D and information D ₁ that has been displayed in pairs on a display device (b) of the client PC09, while viewing the image D, the variable character area of the image D (contractor name, if the corresponding content inconsistent personal information description region) in the case of data information D ₁ corresponding incorrect (image D including addresses) is modified to match the content of the image D (in the figure " during processing the information _{D 1:} 12 ").

  Meanwhile, as described above, the image C that has been downloaded behind the scenes (background) by the prefetching means and stored in the download folder of the standby memory 11 is read (“image C is read: 13” in the figure). ).

Correction processing of the information D ₁ is to be reflected in the information D ₁ that is stored in the magnetic disk device 70 of the DB server 40 when finished.

Information C ₁ corresponding to the image C read from the download folder in the standby memory 11 is read from the magnetic disk device 70 of the DB server 40 and displayed on the display device b in a pair with the image C (display data C ₀ = image C +). information _C 1).

In this example, the user (operator) refers to the image C and the information C ₁ displayed in pairs on a display device (b) of the client PC09, while viewing the image C, the variable character region of the image C (contractor name, if information C ₁ of data corresponding to the personal information description region), such address is not correct modified to match the content of the image C (in the figure "processing information C _1: 14").

  In the meantime, as described above, the image E that has been downloaded behind the scenes by the prefetching means and stored in the download folder of the standby memory 11 is then read out (“Read image E: 15” in the figure). ).

When the correction process of the information C ₁ is completed, the information C ₁ is reflected in the information C ₁ stored in the magnetic disk device 70 of the DB server 40.

Information E ₁ corresponding to the image E read from the download folder of the standby memory 11 is read from the magnetic disk device 70 of the DB server 40 and displayed on the display device b in a pair with the image E (display data E ₀ = image E +). information _E 1). Thereafter, the same processing is repeated.

In this case, the processing of information _{B 1} in the client PC01 ( "processing of information _{B 1:} 06" in the drawing) is prolonged, the client PC09 is to have pre-read image C above (in the figure reads out the "image C: 13 1 are linked to each other as indicated by “α” in FIG. 1 to monitor each other's state, and the prefetching means for the client PC 01 detects that the client PC 09 has prefetched the image C first. Then, a deletion request is issued to the image C on the client PC 01, the image C is deleted from the download folder of the standby memory 03, and a new image F is downloaded (“Destroy image C and download image F in the figure”). : 07 ").

  In the above example, when each prefetching means is linked as shown by “α” in FIG. 1 and the same image is used in another client PC, if the image is already in the standby memory of the own client PC, However, instead of linking the prefetching units with each other, the control unit 35 (see FIG. 1) that manages the entire AP server monitors each prefetching unit to perform the same function. It may be.

Processing of information _{B 1} in the client PC01 (while processing in FIG. "Information _{B 1:} 06) to reflect the information _{B 1} that is stored in the magnetic disk device 70 of the DB server 40 When you are finished, then downloads the standby memory 03 The image F is read from the folder (“Read image F: 08” in the figure), information F ₁ corresponding to the read image F is read from the magnetic disk device 70 of the DB server 40, and the display device a is paired with the image F. (Display data F ₀ = image F + information F ₁ ) Thereafter, the same processing is repeated.

  With the function of the prefetching unit described above, it is possible to prevent the same image from being repeatedly processed by a plurality of client PCs and to smoothly download the prefetched image.

  5 and 6 show examples of display screens of the display device, FIG. 5 shows an example of a screen before correction, and FIG. 6 shows an example of a screen after correction.

In FIG. 5, image A is an example of an address (residence) change notification filed to the Patent Office when the applicant changes his / her address. item (variable data) shows an example obtained by adding by hand the information a ₁ is pre-specified area read by OCR is associated with the item modifiable area variable data is written in the image a The state of the screen displayed as (indicated by a frame) is shown.

The specified items in this example are date, application number, applicant's old address, new address, name (company name), agent's address and name, and OCR's old address of applicant. “6” in the address of is misrecognized as “8”, “Information” in the name is misrecognized as “Clear”, “萩” in the name of the agent is “荻” Akira "is an example of a screen displayed as the image a and the information a ₁ pairs before correction when it is erroneously recognized as" Ichiro ".

FIG. 6 shows that the operator (user) has corrected the contents of the correctable area indicated by the frame of the information A ₁ while viewing the image A based on the screen of the image A and the information A ₁ before correction shown in FIG. This is an example of the screen after correction, in which the above-mentioned misrecognized “address 8” is changed to “address 6”, “clearing” is set to “information”, “荻” is set to “萩”, “ro” is set Each has been modified to “Ryo”.

  Even when the reading and recognition by the OCR are correct, the handwritten character on the screen A itself is corrected to be apparently wrong. The “Toyoshu” in the address field of the agent in the image A of FIG. 5 is correctly recognized as “Toyosu” by OCR reading, but this is clearly a handwritten mistake of “Toyosu”, as shown in FIG. To “Toyosu”.

<Modification>
The DB server is provided with an image management table provided with a pre-use flag for holding the presence / absence of pre-use for each image. When the image is downloaded to one client PC for each image, this is indicated as the pre-use flag. Is set to “1”, and when a download request is received from another client PC, the request is suppressed, and duplicate download and duplicate processing of the same image to a plurality of client PCs are prohibited. It is also possible.

  The processing order (download order) of a plurality of images is not particularly limited in the present invention, but may be determined in advance based on the frequency of use. In particular, in the fixed document variable data correction support system according to the present invention, the download order of images of fixed documents including variable data (for example, contracts, various notification documents, etc.) may be set in the order of standard document creation or reception, When a plurality of client PCs are provided, which client PC is to be assigned to the correct operator may be determined according to the complexity of correction of the standard document to be corrected, the skill level of the correct operator, and the like.

  In the embodiment of the information corresponding to the image of the standard document including the variable data shown in FIGS. 5 and 6, only the variable character data portion is extracted and displayed at the bottom of the screen. In addition, the operator may visually determine whether the variable character data portion is indicated by a frame by displaying all of them, and the image may be corrected as necessary while referring to the image.

  The processing performed by the client server system, fixed document variable data correction support system, screen transition method, fixed document variable data correction support method according to the present invention includes a client PC, a DB server, a CPU and a memory constituting an AP server, This is realized by executing a program corresponding to each process (each means or each step in the claims) by hardware such as a register. Programs corresponding to these processes can be distributed to the market via computer-readable recording media such as FD, CD-ROM, and DVD, and networks such as the Internet.
