  The current page number information 112 and the total page number information 113 are necessary for determining which page information (current page number information 112) is relative to the page number (total page number information 113) of the entire document. This information is used to determine a missing page when restoring a document. These pieces of information are also used when a document is restored by the inserter function.

  Information 114 indicating only text data or all data is information indicating whether the document data recorded in the QR code is only text data or document data including image / font information.

  In addition to the document data of the page (own page), the data (binary) 115 is, for example, document data of other pages such as the document data of the previous page or the subsequent page by the processing of FIG. Are also maintained in binary format.

  Information 116 such as font / image position information is information necessary for faithfully restoring the document, such as font information and image position information used in one page of document data.

  The file storage destination 117 specifies document data to be restored when performing restoration processing from electronic data stored in the server terminal device 700 rather than restoration from document data recorded on paper or a QR code. Document specifying information (information for accessing electronic data).

  For example, the electronic data main body is stored in the directory of the server terminal device 700 connected to the printer 300 over the network, and the path is stored. Alternatively, an identifier for uniquely identifying document data (for example, a file name or the like) or the like may be disabled for electronic data. A method of storing electronic data in a database is also conceivable.

  The update date 118 of the electronic data includes document data creation timing information (in this embodiment, the update date is used) indicating the timing when the paper document to be restored is created when the restoration process is performed from the electronic data, and the electronic data. This is information for confirming whether or not the two-dimensional barcode creation timing information (update date) indicating the creation timing is the same or different.

  In addition, when time is used for the document data creation timing information and the 2D barcode creation timing information, there is a slight difference because it is created by another device. In this case, the error within the predetermined range is the same. You may make it compare as what was produced at time.

Thus, when a paper document is restored from the electronic data stored in the server terminal device 700, the user can select whether or not to restore according to the version of the stored electronic data. The user can restore a desired paper document.
The page end flag information 119 is flag information indicating the end of each page held in the QR code.

  FIG. 5 is a schematic diagram illustrating an example of an analysis result table 120 that holds analysis result information of a paper document using a QR code printed for each page of the paper document in the document restoration system 100 according to the embodiment of the present invention. It is.

  The analysis result table 120 reads a paper document (input document) to be restored with a QR code holding information shown in FIG. 4 by the scanner unit 350 of the printer 300 when the document is restored. The plug-in 105 analyzes the QR code of the data and holds analysis result information including a missing state for each page.

  The analysis result table 120 becomes information for creating an inserter instruction list when a document is restored using the inserter 500, for example. The analysis result table 120 is stored in the external memory 211 or the HDD 304, for example.

  As shown in FIG. 5, the analysis result table 120 includes page number information 121, document presence / absence information 122 indicating whether a document is present or missing, and information (FIG. 4) held in a QR code. Restoration presence / absence information 123 with a QR code indicating whether restoration is possible is held.

  As a result of analyzing the input document with the QR code by the plug-in 105, for example, when the first page paper document is a normal paper document and can be restored with the QR code, as shown in FIG. In “1” of the page number information 121, “original” indicating that there is an original is held as the original presence / absence information 122, and it can be restored using the QR code as the presence / absence information 123 of the QR code. “QROK” is held.

  Further, as a result of analyzing the input document with the QR code by the plug-in 105, for example, when the paper document of the fourth page does not exist, it can be restored from the QR code attached to another paper document. In some cases, as shown in FIG. 5, “4” in the page number information 121 holds “missing” indicating that the document is missing as the document presence / absence information 122, and restoration with the QR code is performed. As the presence / absence information 123, “QROK” indicating that restoration is possible with a QR code is held.

  Further, as a result of analysis of the input document to which the QR code is added by the plug-in 105, for example, when the paper document of the third page does not exist, the restoration is also possible from the QR code attached to another paper document. If it is impossible, as shown in FIG. 5, “3” in the page number information 121 holds “missing” indicating that the document is missing as the document presence / absence information 122, and the QR code is used. As the restoration presence / absence information 123, “QRNG” indicating that restoration is possible with a QR code is held.

  Further, for example, when there is no paper document on the eighth page and it cannot be restored from a QR code attached to another paper document, a QR code attached to another paper document is not possible. If there is data in the file storage location 117 included in the file, as shown in FIG. 5, “8” in the page number information 121 indicates “missing” indicating that the document is missing as the document presence / absence information 122. And “QROK (electronic data)” indicating that restoration is possible with the QR code is held as the presence / absence information 123 of restoration with the QR code.

  In this case, since there is an upper limit on the data capacity that can be stored in the QR code, if there is a case where document data exceeding the upper limit is stored, the corresponding page is not stored as document data, but the server terminal device 700 The document data is stored, and the QR code is configured to record the file storage destination 117 without recording the data (binary) 115 relating to the page and the information 116 such as font / image position information. It corresponds.

As a matter of course, when document data exceeding the upper limit is converted into a QR code even if a document exists, “document” is included in the document presence / absence information 122, and “CROK ( Electronic data) ”is recorded.
Next, a processing procedure in the above-described QR code creation processing will be described.

  FIG. 6 is a flowchart showing an example of a processing procedure in the QR code creation processing of the document restoration system 100 according to the embodiment of the present invention. FIG. 7 is a flowchart showing an example of a detailed processing procedure of step S108 shown in FIG.

FIG. 8 is a flowchart showing an example of a detailed processing procedure of step S105 shown in FIG. 6 to 8 are mainly performed by the plug-in 105 shown in FIG. 1-2, that is, the CPU 201 of the client terminal device 200 (or the CPU 301 of the printer 300).
9 to 16 are schematic diagrams illustrating examples of setting screens used in the QR code creation process of the document restoration system 100 according to the embodiment of the present invention.

  This setting screen is displayed on, for example, the CRT 210 when the plug-in 105 is provided in the client terminal device 200, for example, and is displayed on the operation unit 320, for example, when the plug-in 105 is provided in the printer 300, for example. It is displayed on the display screen 321.

Also, the setting information related to the QR code creation process set on the setting screens of FIGS. 9 to 16 is stored in, for example, the external memory 211 or the HDD 304 according to the device in which the plug-in 105 is provided.
The QR code creation process will be described below with reference to FIGS.
Here, before explaining the flowcharts shown in FIGS. 6 to 8, first, the setting screens of FIGS. 9 to 16 will be explained.

The setting screen 601 relating to QR code creation shown in FIG. 9 is configured to be able to set a creation data range, a QR code creation method, and whether to narrow the creation data to text for each page of document data.
Specifically, the setting screen 601 for QR code creation in FIG. 9 shows that “only before and after and own page” 611 is selected as the creation data range.

  When “only front and back and own page” 611 is selected, the own page (n) for printing the QR code, the previous page (n−1) of the n page, and the subsequent page (n + 1) of the n page QR code including the document data is created.

  If n is the first page, the previous page is the last page of this document data. If n is the last page, the subsequent page is the first page of this document data.

  In addition, the setting screen 601 relating to QR code creation in FIG. 9 shows that “create multiple QR codes” 612 is selected as the QR code creation method.

When “Create multiple QR codes” 612 is selected, the total data size of all pages in “Only before and after and own page” 611 selected as the creation data range is the capacity allowed by the QR code. If it exceeds the limit, these document data are divided to generate a plurality of QR codes.
When the OK button 613 is pressed in this state, the setting information is set for the plug-in 105.

  The setting screen 601 related to QR code creation shown in FIG. 10 shows that “squeeze created data to text” 614 that is not set in FIG. 9 is further selected with respect to the setting screen shown in FIG. Has been.

By setting “squeeze created data to text” 614, it is possible to create document data of only text data by using a plurality of QR codes by excluding image data.
When the OK button 613 is pressed in this state, the setting information is set for the plug-in 105.

  In the setting screen 601 relating to QR code creation shown in FIG. 11, “only before and after and own page” 611 is selected as the creation data range, and “create single QR code” 615 is selected as the QR code creation method. The situation is shown.

  When the “create single QR code” 615 is selected, the total data size of all pages in the “front and back and own page only” 611 selected as the creation data range is the capacity allowed by the QR code. Even if the number is exceeded, only the creation of a single QR code is permitted.

  Further, when “create single QR code” 615 is selected as the QR code creation method, the detail button 616 becomes effective. When the detail button 616 is pressed, a detail setting screen 701 shown in FIG. 12 is displayed.

The detailed setting screen 701 shown in FIG. 12 is configured to be able to set the priority order of pages for creating QR codes. For example, if you place the cursor on your own page (your page) 711 with the highest priority, the back side will be colored, and if you want to lower that priority, press the down button 713 to the desired location, Conversely, when the priority order is to be raised, the up button 712 is pressed.
When the OK button 714 is pressed, the priority order of each page (priority orders 1 to 3 in the case of three pages shown in FIG. 12) is set.

  When the OK button 714 is pressed, the screen returns to the setting screen 601 for QR code creation. When the OK button 613 is pressed in this state, the setting information is set for the plug-in 105. .

  The setting screen 601 related to QR code creation shown in FIG. 13 shows that “squeeze created data to text” 614 that is not set in FIG. 11 is further selected with respect to the setting screen shown in FIG. Has been.

By setting the “squeeze created data to text” 614, document data including only text data is created with a single QR code, excluding image data.
When the OK button 613 is pressed in this state, the setting information is set for the plug-in 105.

In the setting screen 601 relating to QR code creation shown in FIG. 14, a state where “Fit to QR code size” 617 is selected as the creation data range is shown.
When this “fit to QR code size” 617 is selected, the setting item of the QR code creation method cannot be selected at the same time.

  Further, when “Fit to QR code size” 617 is selected as the creation data range, the detail button 618 is enabled. When the detail button 618 is pressed, a detail setting screen 801 shown in FIG. 15 is displayed.

  When “Fit to QR code size” 617 is selected as the creation data range, the priority order for each page for creating the QR code set on the detailed setting screen 801 shown in FIG. 15 according to the capacity allowed by the QR code. A single QR code is created according to

  The detailed setting screen 801 shown in FIG. 15 is configured to be able to set the priority order for each page for creating a QR code. For example, if you place the cursor on a page close to you (page close to your page) 811 that has the highest priority, the back will be colored, and if you want to lower that priority, press the down button 813 to the desired location. If the user wants to raise the priority order, the up button 812 is pressed.

  Here, the priority selection unit is a unit of pages such as a page close to itself including its own page (own page), a page in front of it, and a page behind it. When the OK button 814 is pressed, the priority order for each page (priority orders 1 to 3 in the case of the three page units shown in FIG. 15) is set.

  When the OK button 814 is pressed, the screen returns to the setting screen 601 related to QR code creation. When the OK button 613 is pressed in this state, the setting information is set for the plug-in 105. .

The setting screen 601 related to QR code creation shown in FIG. 16 shows that “squeeze the created data to text” 614 that is not set in FIG. 14 is further selected with respect to the setting screen shown in FIG. Has been. By setting this “squeezed creation data to text” 614, document data of only text data is created with a QR code, excluding image data. When the OK button 613 is pressed in this state, the setting information is set for the plug-in 105.
Next, the flowcharts shown in FIGS. 6 to 8 will be described.

  When performing the processing of the flowcharts shown in FIGS. 6 to 8, it is assumed that the setting information setting on the setting screen 601 relating to the QR code creation described above has already been performed for each page of the target document data. .

  First, in step S <b> 101 of FIG. 6, the plug-in 105 temporarily stores document data (PDL) to be printed in the document data temporary storage unit 106. Here, the document data temporary storage unit 106 corresponds to, for example, the external memory 211 or the HDD 304.

  Subsequently, in step S102, the plug-in 105 sets A as the total number of pages of the document data (PDL) temporarily stored in step S101. This page total number A corresponds to, for example, the total page number information 113 shown in FIG.

  Subsequently, in step S103, the plug-in 105 sets the variable a indicating the QR code creation target page to 1 in the document data (PDL) temporarily stored in step S101. As a result, the QR code creation target page (own page) a is set.

  In step S104, for each page a, page identification information (file name for uniquely identifying the page is created for the document data (PDL) temporarily stored in step S101). Or the document data may be included and stored for each page of the document data), the server terminal device 700 stores the document data in its own predetermined directory (electronic data storage unit 702). The electronic data corresponding to is received and stored.

  Note that a predetermined location may be used as a directory, or the setting screen 601 may be configured so that a directory that is a storage destination of document data (PDL) can be specified on the setting screen 601.

  Subsequently, in step S105, the plug-in 105 determines that the creation data range of the QR code creation target page (own page) a is based on the setting information set on the setting screen 601 related to QR code creation. It is determined whether only the previous and subsequent pages are set or the size is matched with the QR code size.

  Specifically, in this step S105, on the setting screen 601 shown in FIG. 9 etc., “Only before and after and own page” is selected as the creation data range, or “Fit to QR code size” is selected. It is determined according to whether it is.

  As a result of the determination in step S105, when the created data range matches the QR code size (that is, “Fit to QR code size” 617 is selected and set as in the setting screen 601 shown in FIGS. 14 and 16) ) Proceeds to step S106.

  In step S106, the plug-in 105 performs a single QR code creation process in accordance with the QR code size. Details of step S106 will be described later with reference to FIG. When the process of step S106 is completed, the process proceeds to step S118.

  On the other hand, as a result of the determination in step S105, when the creation data range is only the own page and its preceding and following pages (that is, “only before and after and its own page” as in the setting screen 601 shown in FIGS. 9 to 11 and 13). If 611 is selected and set), the process proceeds to step S107.

  In step S107, the plug-in 105 creates one or a plurality of QR codes on the QR code creation target page (own page) a based on the setting information set on the setting screen 601 for QR code creation. It is determined whether.

  Specifically, in step S107, whether “Create multiple QR codes” is selected as the QR code creation method on the setting screen 601 shown in FIG. 9 or the like, or “Create single QR code” is displayed. It is determined according to whether it is selected.

As a result of the determination in step S107, a single QR code is created (that is, “Create a single QR code” 615 is selected and set as in the setting screen 601 shown in FIGS. 11 and 13). In step S108, the process proceeds to step S108.
In step S108, the plug-in 105 performs a single QR code creation process.
Details of step S108 will be described later with reference to FIG. When the process of step S108 ends, the process proceeds to step S118.

  On the other hand, when a plurality of QR codes are created as a result of the determination in step S107 (that is, “Create a plurality of QR codes” 612 is selected and set as in the setting screen 601 shown in FIGS. 9 and 10). In the case), the process proceeds to step S109.

  In step S109, the plug-in 105 determines whether to create only text data as data in the set creation data range based on the setting information set on the setting screen 601 for QR code creation. .

  Specifically, in this step S109, determination is made depending on whether or not “squeeze created data to text” is selected on the setting screen 601 shown in FIG.

  As a result of the determination in step S109, not only the text data is created, but all the data in the created data range page is created (that is, as in the setting screen 601 shown in FIG. If “squeeze” is set without being selected), the process proceeds to step S110.

  When the process proceeds to step S110, the plug-in 105 determines that the document data (PDL) temporarily stored in step S101 is the creation data range of its own page (n pages), the previous page (n-1 pages), and The document data of the back page (n + 1) is read to determine the document data size.

On the other hand, when only the text data is created as a result of the determination in step S109 (that is, when “squeeze created data to text” 614 is selected and set as in the setting screen 601 shown in FIG. 10). The process proceeds to step S111.
In step S111, the plug-in 105 performs an extraction process for extracting only text data from the document data (PDL) temporarily stored in step S101.

  Subsequently, in step S112, the plug-in 105 determines that the generated data range of the text data extracted in step S111 is its own page (n page), the previous page (n-1 page), and the subsequent page. The text data of (n + 1) is read and the document data size is determined.

  In the example shown in FIG. 6, first, only text data is extracted from the document data (PDL) temporarily stored in step S101 (S111), and then the text data of the pages in the created data range from the extracted text data. Is shown (S112), but the present embodiment is not limited to this mode.

For example, as in step S110, first, from the document data (PDL) temporarily stored in step S101, the own data page (n pages), the previous page (n-1 pages), and its creation data range. Even in a mode in which the document data of the back page (n + 1) is read and then only the text data is extracted from the page of the read creation data range, it is applicable to this embodiment.
When the process of step S110 ends, or when the process of step S112 ends, the process proceeds to step S113.

  In step S113, the plug-in 105 compares the data size read in step S110 or step S112 with the capacity allowed by the created QR code, and the capacity allowed by the QR code is equal to or larger than the read data size. It is determined whether or not.

Here, in this example, 80% of the entire size of the QR code is set as the capacity allowed by the QR code. This is because the capacity allowed by this QR code corresponds to the allowable amount that can be set in the data (binary) 115 of the information 110 held by the QR code shown in FIG.
Therefore, the data of the data size that is equal to or smaller than the allowable amount is QR-coded.
If it is determined in step S113 that the capacity allowed by the QR code is equal to or larger than the read data size, the process proceeds to step S114.

  In step S114, the plug-in 105 converts the document data read in step S110 or step S112 into a barcode and performs a single QR code creation process. Thereafter, the process proceeds to step S117.

  On the other hand, as a result of the determination in step S113, if the capacity allowed by the QR code is not equal to or larger than the read data size (that is, if the capacity allowed by the QR code is less than the read data size), the process proceeds to step S115. move on.

  In step S115, the plug-in 105 converts the document data read in step S110 or step S112 into a barcode and performs a process for creating one QR code.

  At this time, the file storage destination 117 includes identification information for identifying the document data in step S104, that is, page identification information regarding the electronic data stored in the server terminal device 700, a path to the directory of the server terminal device 700, and the like. Set information including.

  Subsequently, in step S116, the plug-in 105 determines whether there is any remaining document data not created as a QR code among the document data read in step S110 or step S112.

  As a result of the determination in step S116, if there is remaining document data not created as a QR code among the document data read in step S110 or step S112, the number of QR codes to be created is set to be increased by one. Returning to step S115, a process for creating one QR code in the remaining document data is performed.

  On the other hand, as a result of the determination in step S116, if there is no remaining document data not created as a QR code among the document data read in step S110 or step S112, the process proceeds to step S117.

  In step S117, the plug-in 105 places the QR code created in step S114 or step S115 at a predetermined position on the page (own page) a of the QR code creation target of the document data (PDL) temporarily stored in step S101. Place and attach.

  When a plurality of QR codes are created in the loop from step S115 to step S116, each QR code is shifted and arranged at a predetermined position on the page (own page) a for which the QR code is created.

  Subsequently, in step S118, the plug-in 105 determines whether or not the variable a indicating the QR code generation target page (self page) is smaller than the total page number A of the document data set in step S102.

  As a result of the determination in step S118, if the variable a indicating the QR code generation target page (own page) is smaller than the total page number A of the document data set in step S102, the QR code generation processing is performed. It is determined that all pages of the document data temporarily stored in S101 have not been performed, and the process proceeds to step S119.

  In step S119, the plug-in 105 adds 1 to the variable a indicating the QR code creation target page (self page) to change the QR code creation target page a. And the process after step S105 is performed again with respect to the page a changed by step S119.

  On the other hand, if it is determined in step S118 that the variable a indicating the QR code creation target page (own page) is equal to or greater than the total page number A of the document data set in step S102, QR code creation processing is performed. Is performed for all pages of the document data temporarily stored in step S101, and the processing in the flowchart shown in FIG.

After that, when the user instructs the print processing of a series of document data with a QR code attached to each page by the processing in FIG. 6, the CPU 301 of the printer 300 causes the printer unit 340 to print the series of document data. The processing is performed, and the series of documents is printed out on a sheet (recording medium) (first output step). That is, document data including a QR code is printed for each sheet.
Next, details of the single QR code creation process in step S107 shown in FIG. 6 will be described with reference to FIG.

  When the process of step S107 of FIG. 6 is started, first, in step S201 of FIG. 7, the plug-in 105 creates a QR code based on the setting information set on the setting screen 601 related to QR code creation. Determine page priority.

  Specifically, in step S201, the detail button 616 is pressed on the setting screen 601 shown in FIG. 11 or 13 to display the detailed setting screen 701 shown in FIG. Based on the priority order, the priority order of pages for generating the QR code is determined.

  That is, in this step S201, when the data cannot be stored in a single QR code created by the total data size of the current page, the previous page, and the subsequent page, based on the priority order determined here. This is a process for storing page data in a QR code.

  Here, in the present embodiment, based on the setting on the detailed setting screen 701 shown in FIG. 12, the own page (own page) is determined as the priority order 1 and the previous page in the own page (own page) as the priority order 2. It is assumed that one of the next page and the subsequent page is determined, and the other page in the priority order 2 is determined as the priority order 3.

  Subsequently, in step S202, the plug-in 105 determines whether to create only text data as data of the set creation data range based on the setting information set on the setting screen 601 for QR code creation. Determine.

  Specifically, in step S202, the determination is made according to whether or not “squeeze the created data into text” is selected on the setting screen 601 shown in FIG.

  As a result of the determination in step S202, not only text data is created, but all data of pages in the created data range is created (that is, as in the setting screen 601 shown in FIG. If “squeeze” is set without being selected), the process proceeds to step S203.

  In step S203, the plug-in 105 has priority 1 among the document data (PDL) temporarily stored in step S101 of FIG. 6 based on the setting information set on the setting screen 601 for QR code creation. Read document data.

  Here, in the present embodiment, since the page (own page), that is, the page for which the QR code is to be created is determined as priority 1 in step S201, in this example, the document data of the own page is determined. Will be read.

  Subsequently, in step S204, the plug-in 105 determines and stores the data size of the document data read in step S203. Here, when the process of step S203 is repeated, the data size of the document data is stacked to determine the read data size.

  Subsequently, in step S205, the plug-in 105 compares the read data size determined in step S204 with the capacity allowed by the QR code to be created, and the capacity allowed by the QR code is determined based on the read data size. Or the document data of the last priority page is not read.

  Here, in this example, 80% of the overall size of the QR code is set as the capacity allowed by the QR code to be created in the same manner as in step S113 of FIG. 6 described above.

If the result of determination in step S205 is affirmative, the priority is increased by one with respect to the priority of the document data read in step S203, the process returns to step S203, and the processing from step S203 onward is performed again. Do.
On the other hand, if the result of determination in step S205 is negative, the process proceeds to step S210.

  As a result of the determination in step S202, when only text data is created (that is, when “squeeze created data to text” 614 is selected and set as in the setting screen 601 shown in FIG. 13), step The process proceeds to S206.

In step S206, the plug-in 105 has priority 1 among the document data (PDL) temporarily stored in step S101 of FIG. 6 based on the setting information set on the setting screen 601 for QR code creation. An extraction process for extracting only text data from document data is performed.
Subsequently, in step S207, the plug-in 105 reads the text data extracted in step S206.

  Subsequently, in step S208, the plug-in 105 determines and stores the data size of the text data read in step S207. Here, when the process of step S207 is repeated, the data size of the text data is stacked to determine the read data size.

  Subsequently, in step S209, the plug-in 105 compares the read data size determined in step S208 with the capacity allowed by the created QR code, and the capacity allowed by the QR code is determined based on the read data size. Or the text data of the last priority page is not read.

  Here, in this example, 80% of the overall size of the QR code is set as the capacity allowed by the QR code to be created in the same manner as in step S113 of FIG. 6 described above.

If the result of determination in step S209 is affirmative, the priority is increased by one with respect to the priority of the text data extracted and read in steps S206 and S207, the process returns to step S206, and step S206 is again performed. Perform the following processing.
On the other hand, if the result of determination in step S209 is negative, the process proceeds to step S210.

  In step S210, the plug-in 105 determines whether the capacity allowed by the QR code is the same (equal) as the read data size determined in step S204 or step S208.

  As a result of the determination in step S210, if the capacity allowed by the QR code is not the same (equal) as the read data size determined in step S204 or step S208, the process proceeds to step S211.

  In step S211, the plug-in 105 performs processing for deleting the data of the page read last in step S203 or step S207. As a result, the data can be converted into a QR code within the capacity range permitted by the QR code.

  When the process of step S211 is completed, or when it is determined in step S210 that the capacity allowed by the QR code is the same (equal) as the read data size determined in step S204 or step S208, Proceed to step S212.

  In step S212, the plug-in 105 converts the document data read in step S203 or step S207 into a barcode and performs a single QR code creation process. At this time, information including the page identification information and the path to the directory in step S104 is set in the file storage destination 117.

The data deleted in step S211, that is, the data out of the capacity allowed by the QR code, is information 114 indicating only text data or all data, data (binary) 115, font / image position information. The information 116 such as the current page number information 112, the file storage destination 117 (for example, information related to the storage area of the electronic data storage unit 702), and the information related to the update date 118 are created as QR codes.

Subsequently, in step S213, the plug-in 105 determines the QR code created in step S212 as the QR code creation target page (own page) a of the document data (PDL) temporarily stored in step S101 in FIG. Place and attach to. Thereafter, the process proceeds to step S118 of FIG. 6 described above, and the processes after step S118 are performed.
Next, details of the single QR code creation process in accordance with the QR code size in step S106 shown in FIG. 6 will be described with reference to FIG.

  When the process of step S106 of FIG. 6 is started, first, in step S301 of FIG. 8, the plug-in 105 creates a QR code based on the setting information set on the setting screen 601 related to QR code creation. Determine the priority for each page.

  Specifically, in step S301, the detail button 618 is pressed on the setting screen 601 shown in FIG. 14 or 16 to display the detailed setting screen 801 shown in FIG. Based on the priority order, the priority order of the page unit for creating the QR code is determined.

  Here, in the present embodiment, based on the setting on the detailed setting screen 801 shown in FIG. 15, a page close to you including your page (your page) is determined as priority 1 and close to you as priority 2 One page unit of the front page or the rear page in the page is determined, and the other page unit in the priority order 2 is determined as the priority order 3.

  Subsequently, in step S302, the plug-in 105 determines whether to create only text data as data of the set creation data range based on the setting information set on the setting screen 601 for QR code creation. Determine.

  As a result of the determination in step S302, not only text data is created, but all data of pages in the created data range is created (that is, as in the setting screen 601 shown in FIG. If “squeeze” is set without being selected), the process proceeds to step S303.

  In step S303, the plug-in 105 has priority 1 among the document data (PDL) temporarily stored in step S101 of FIG. 6 based on the setting information set on the setting screen 601 for QR code creation. Read document data in page units.

Here, in this embodiment, since a page close to itself including its own page (own page) is determined as priority 1 in step S301, in this example, first, a page for which a QR code is to be created is included. The document data for each page is read.
Subsequently, in step S304, the plug-in 105 determines and stores the data size of the document data read in step S303.
Here, when the process of step S303 is repeated, the data size of the document data is stacked to determine the read data size.

  Subsequently, in step S305, the plug-in 105 compares the read data size determined in step S304 with the capacity allowed by the QR code to be created, and the capacity allowed by the QR code is determined based on the read data size. It is determined whether or not it is larger.

  Here, in this example, 80% of the overall size of the QR code is set as the capacity allowed by the QR code to be created in the same manner as in step S113 of FIG. 6 described above.

  Here, it is assumed that the data size of the document data (PDL) temporarily stored in step S101 in FIG. 6 is larger than the capacity allowed by the QR code created in step S305 (that is, the detailed setting shown in FIG. 15). It is assumed that processing is performed up to the page unit of the last priority set on the screen 801, and the loop of step S303 to step S305 is not continuously repeated).

  As a result of the determination in step S305, when the capacity allowed by the QR code is larger than the read data size, the priority is increased by one with respect to the priority of the document data read in step S303, and step S303 is executed. Returning to step S303, the processes after step S303 are performed again.

  On the other hand, as a result of the determination in step S305, if the capacity allowed by the QR code is not larger than the read data size (below), the process proceeds to step S310.

  If only the text data is created as a result of the determination in step S302 (that is, when “squeeze created data to text” 614 is selected and set as in the setting screen 601 shown in FIG. 16), step The process proceeds to S306.

In step S306, the plug-in 105 has priority 1 among the document data (PDL) temporarily stored in step S101 of FIG. 6 based on the setting information set on the setting screen 601 for QR code creation. An extraction process for extracting only text data from document data in page units is performed.
Subsequently, in step S307, the plug-in 105 reads the text data extracted in step S306.

  Subsequently, in step S308, the plug-in 105 determines and stores the data size of the text data read in step S307. Here, when the process of step S307 is repeated, the data size of the text data is stacked to determine the read data size.

  Subsequently, in step S309, the plug-in 105 compares the read data size determined in step S308 with the capacity allowed by the QR code to be created, and the capacity allowed by the QR code is determined based on the read data size. It is determined whether or not it is larger.

  Here, in this example, 80% of the overall size of the QR code is set as the capacity allowed by the QR code to be created in the same manner as in step S113 of FIG. 6 described above.

  Here, the data size of the text data extracted from the document data (PDL) temporarily stored in step S101 in FIG. 6 is assumed to be larger than the capacity allowed by the QR code created in step S309 (that is, It is assumed that the processing is performed up to the page unit of the last priority set on the detailed setting screen 801 shown in FIG. 15, and the loop of step S306 to step S309 is not continuously repeated).

  As a result of the determination in step S309, if the capacity allowed by the QR code is larger than the read data size, the priority is increased by one with respect to the priority of the text data extracted and read in steps S306 and S307. Then, the process returns to step S306, and the processes after step S306 are performed again.

  On the other hand, as a result of the determination in step S309, if the capacity permitted by the QR code is not larger than the read data size (below), the process proceeds to step S310.

  In step S310, the plug-in 105 determines whether the capacity allowed by the QR code is the same (equal) as the read data size determined in step S304 or step S308.

As a result of the determination in step S310, if the capacity allowed by the QR code is not the same (equal) as the read data size determined in step S304 or step S308, the process proceeds to step S311.
In step S311, the plug-in 105 performs a process of deleting the data of the page read last in step S303 or step S307.

  When the process of step S311 is completed, or when it is determined in step S310 that the capacity allowed by the QR code is the same (equal) as the read data size determined in step S304 or step S308, The process proceeds to step S312.

  In step S312, the plug-in 105 converts the document data read in step S303 or S307 into a barcode and performs a single QR code creation process. At this time, specific information for specifying document data such as page identification information and information including the path to the directory of the server terminal device 700 in step S104 is set in the file storage destination 117.

It should be noted that the data deleted in step S311 excludes information 114 indicating only text data or all data, data (binary) 115, information 116 such as font / image position information, and the current page number information 112. Information relating to document data including the file storage destination 117 and the update date 118 is created by converting it into a QR code.

Subsequently, in step S313, the plug-in 105 determines that the QR code created in step S312 is a predetermined position of the page (own page) a of the QR code creation target of the document data (PDL) temporarily stored in step S101 of FIG. Place and attach to. Thereafter, the process proceeds to step S118 of FIG. 6 described above, and the processes after step S118 are performed.
Next, a processing procedure in document restoration processing using a QR code will be described.
FIG. 17 is a flowchart illustrating an example of a processing procedure in document restoration processing using a QR code of the document restoration system 100 according to the embodiment of the present invention.
FIG. 18 is a flowchart illustrating an example of a detailed processing procedure of step S420 illustrated in FIG.

  FIG. 19 is a flowchart illustrating an example of a detailed processing procedure of step S502 illustrated in FIG. FIG. 29 is a flowchart illustrating an example of a detailed processing procedure of step S516 illustrated in FIG.

FIGS. 20 to 28 and FIGS. 30 to 31 show the operation unit 320 of the printer 300 shown in FIG. 3 during the document restoration process using the QR code of the document restoration system 100 according to the embodiment of the present invention. It is a schematic diagram which shows an example of the operation screen displayed on the display screen 321.
Hereinafter, a document restoration process using a QR code will be described with reference to FIGS. First, the flowchart shown in FIG. 17 will be described.

  First, in step S401 in FIG. 17, the CPU 301 of the printer 300 performs processing for displaying the copy mode selection screen 901 illustrated in FIG. 20 on the display screen 321 of the operation unit 320 based on an input instruction to the operation unit 320 by the user. .

  Subsequently, in step S402, the CPU 301 of the printer 300 determines whether or not the restoration copy button 912 has been selected by the user pressing the restoration copy button 912 on the copy mode selection screen 901 shown in FIG.

  If the result of determination in step S402 is that restoration copy has been selected, processing proceeds to step S403. When the processing proceeds to step S403, the CPU 301 of the printer 300 displays a pre-document analysis confirmation screen 902 shown in FIG. 21 on the display screen 321 of the operation unit 320, which includes a guidance message for scanning to analyze the document to be restored. Perform the process.

Thereafter, a series of paper documents to be restored by the user (in this paper document, the QR code described above is printed for each paper document) is set in the scanner unit 350, and a confirmation screen before document analysis shown in FIG. When the OK button 913 902 is pressed by the user, in step S404, the CPU 301 of the printer 300 controls the scanner unit 350 to scan the paper document.
If the user presses the cancel button 914 on the pre-document analysis confirmation screen 902 shown in FIG. 21, the scan process in step S404 is not performed.

Subsequently, in step S405, the plug-in 105 (specifically, the CPU 201 when the plug-in is provided in the client terminal device 200, and the CPU 301 when the plug-in is provided in the printer 300) For each page of the paper document scanned in step S404, the QR code attached to the page of the paper document is read.
Subsequently, in step S406, the plug-in 105 performs an analysis process on the information (FIG. 4) held in the QR code read in step S405.
Subsequently, in step S407, the plug-in 105 holds the analysis result analyzed in step S406 in the analysis result table 120 shown in FIG.

  As a method of holding the analysis result, for example, when an input document with a QR code is analyzed by the plug-in 105 and the paper document is a normal paper document and can be restored with the QR code, “Original” indicating that there is an original is stored as the presence / absence information 122 of the original corresponding to the page number information 121, and “QROK” indicating that restoration is possible using the QR code as the presence / absence information 123 of restoration using the QR code. Retained.

  In addition, when the plug-in 105 analyzes the input document to which the QR code is attached, the paper document does not exist and can be restored from the QR code attached to another paper document. “Missing” indicating that the document is missing is held as the document presence / absence information 122 corresponding to the page number information 121 of the page, and it can be restored with the QR code as the restoration information 123 with QR code. “QROK” shown is held.

  Further, when the plug-in 105 analyzes the input document to which the QR code is attached, the paper document does not exist and cannot be restored from the QR code attached to another paper document. Holds “missing” indicating that the original is missing as the original presence / absence information 122 corresponding to the page number information 121 of the corresponding page, and cannot be restored with the QR code as the restoration presence / absence information 123 with the QR code. “QRNG” indicating that the

  Furthermore, as a result of analyzing the input document to which the QR code is attached by the plug-in 105, there is no paper document, and it is impossible to restore from the QR code attached to another paper document. If the data (binary) 115 included in the QR code attached to another paper document and the information 116 such as the font / image position information do not contain data and the file storage destination 117 contains data, the corresponding “Missing” indicating that the document is missing is held as the document presence / absence information 122 corresponding to the page number information 121 of the page, and it can be restored with the QR code as the restoration information 123 with QR code. “QROK (electronic data)” is held.

Subsequently, in step S408, the plug-in 105 determines whether there is a next document (paper) scanned in step S404. If the result of this determination is that there is the next document (paper) scanned in step S404, the process returns to step S405, and the processing from step S405 onward is performed again.
On the other hand, if the result of determination in step S408 is that there is no next document (paper) scanned in step S404, processing proceeds to step S409.

In step S409, the plug-in 105 determines that pages that cannot be restored based on the analysis result information stored in the analysis result table 120 illustrated in FIG. It is determined whether or not the ratio is greater than 30%. Specifically, the determination in step S409 is performed based on the restoration presence / absence information 123 in the QR code held in the analysis result table 120 illustrated in FIG.
If the result of determination in step S409 is that there are more pages that cannot be restored than the reference value, processing proceeds to step S410.

  In step S410, the CPU 301 of the printer 300 performs processing for displaying the document analysis result screen 903 shown in FIG. 22 on the display screen 321 of the operation unit 320. In the document analysis result screen 903 shown in FIG. 22, page information relating to a page that cannot be restored is displayed.

Subsequently, in step S411, the CPU 301 of the printer 300 determines whether or not to restore the restoration target document by pressing the restoration button 915 by the user on the document analysis result screen 903 shown in FIG.
As a result of the determination in step S411, when the restore button 915 is pressed to restore the document to be restored, the process proceeds to step S413.

On the other hand, as a result of the determination in step S411, when the restoration target document is not restored (when the non-restoration button 916 on the document analysis result screen 903 shown in FIG. 22 is pressed), the processing in the flowchart shown in FIG. Exit.
If the number of pages that cannot be restored is not greater than the reference value as a result of the determination in step S409, the process proceeds to step S412.

In step S412, the plug-in 105 performs a missing page determination process to determine whether there is a missing page, based on the analysis result information held in the analysis result table 120 illustrated in FIG. The determination in step S412 is specifically performed based on the document presence / absence information 122 held in the analysis result table 120 shown in FIG.
If there is a missing page as a result of the determination in step S412, the process proceeds to step S413.

  In step S 413, the CPU 301 of the printer 300 performs processing for displaying the document analysis result screen 904 shown in FIG. 23 on the display screen 321 of the operation unit 320. In the document analysis result screen 904 shown in FIG. 23, page information related to the missing page (information on the number of missing pages) is displayed.

  Subsequently, in step S414, the CPU 301 of the printer 300 performs an operation from the user to the original document all print button 917, the missing page only print button 918, and the inserter use check box 919 on the document analysis result screen 904 illustrated in FIG. Accept selection.

  Subsequently, in step S <b> 415, the CPU 301 of the printer 300 performs processing for displaying the document restoration method selection screen 905 shown in FIG. 24 on the display screen 321 of the operation unit 320.

  If QROK (electronic data) exists as a result of the analysis in step S407, confirmation information such as “There is a page that can be restored only from electronic data” is displayed to display the next step. It is also possible to guide the user's operation selection in S416.

  In step S416, the CPU 301 of the printer 300 selects an operation from the user for the text data only restore button 920, the paper data to copy button 921, and the electronic data to restore button 922 on the document restoration method selection screen 905 shown in FIG. Accept.

  Subsequently, in step S <b> 417, the CPU 301 of the printer 300 performs processing for displaying the QR code creation selection screen 906 shown in FIG. 25 on the display screen 321 of the operation unit 320.

  Subsequently, in step S418, the CPU 301 of the printer 300 accepts an operation selection from the user for the button 923 and the non-button 924 on the QR code creation selection screen 906 shown in FIG.

  Subsequently, in step S419, the CPU 301 of the printer 300 performs processing for displaying the restoration confirmation screen 907 shown in FIG. 26 on the display screen 321 of the operation unit 320.

  Thereafter, when the user presses the OK button 925 on the restoration confirmation screen 907 shown in FIG. 26, the plug-in 105 responds to the user's operation selection on the operation screen shown in FIGS. The document data is restored.

  Details of step S420 will be described later with reference to FIG. If the user presses the NG button 926 on the restoration confirmation screen 907 shown in FIG. 26, the restoration process in step S420 is not performed.

Subsequently, in step S421, the CPU 301 of the printer 300 controls the printer unit 340 to print out the document data restored in step S420 on a sheet (second output step). Thereafter, the processing in the flowchart shown in FIG.
If there is no missing page as a result of the determination in step S412, the process proceeds to step S422.

  In step S 422, the CPU 301 of the printer 300 performs processing for displaying the confirmation screen 908 shown in FIG. 27 on the display screen 321 of the operation unit 320. Thereafter, when the user presses the OK button 927 on the confirmation screen 908 shown in FIG. 27, the processing in the flowchart shown in FIG. 17 ends.

  In addition, when the restoration copy is not selected as a result of the determination in step S402 (that is, when the normal copy button 911 is pressed by the user on the copy mode selection screen 901 shown in FIG. 20 and the normal copy is selected). Advances to step S423.

  Thereafter, when the user sets a paper document to be copied in the scanner unit 350 and gives an instruction to copy the paper document, in step S423, the CPU 301 of the printer 300 controls the scanner unit 350 to control the paper document. Scan the document.

Subsequently, in step S424, the CPU 301 of the printer 300 controls the printer unit 340 to print the document data scanned in step S423 on a sheet. Thereafter, the processing in the flowchart shown in FIG.
Next, the details of the document data restoration processing in step S420 shown in FIG. 17 will be described with reference to FIG.

  When the process of step S420 in FIG. 17 is started, first, in step S501 of FIG. 18, the plug-in 105 accepts the button (917, 918) of the document analysis result screen 904 shown in FIG. In accordance with the operation selection, it is determined whether to print the entire original document or only the missing page.

If only the missing page is printed as a result of the determination in step S501 (when the operation button is selected for the missing page only print button 918 in the document analysis result screen 904 shown in FIG. 23), the process proceeds to step S502.
In step S502, the plug-in 105 performs restoration processing for only missing pages.

Details of step S502 will be described later with reference to FIG. When the process of step S502 is completed, the process of the flowchart shown in FIG. 18 is finished (that is, the process of step S420 shown in FIG. 17 is finished), and then the process proceeds to step S421 (printing process) of FIG. Become.

On the other hand, as a result of the determination in step S501, when all the original documents are printed (when the print all original document button 917 is selected in the document analysis result screen 904 shown in FIG. 23), the process proceeds to step S503.
In step S503, the plug-in 105 refers to the analysis result table 120 shown in FIG. 5 for each page of the document to be restored.

Subsequently, in step S504, the plug-in 105 creates an original document for each page of the document to be restored based on the analysis result information held in the analysis result table 120 shown in FIG. 5 referred to in step S503. It is determined whether or not it can be restored. Specifically, the determination in step S504 is performed based on the document presence / absence information 122 and the restoration presence / absence information 123 in the QR code held in the analysis result table 120 shown in FIG.
If the result of determination in step S504 is that there is no original document and restoration is not possible (in the case of QRNG), the process proceeds to step S515.
On the other hand, as a result of the determination in step S504, if the original document is present or can be restored, the process proceeds to step S505.

  Even if there is no original document and it cannot be restored (in the case of QRNG), a process is added between step S504 and step S515 so that the document data is restored from the electronic data stored in the server terminal device 700. May be.

  When only the missing page is restored, the electronic data saved in the server terminal device 700 corresponding to the missing page from the QR code information (specifically, the file saving destination 117) printed on the previous and next pages. It is also possible to obtain and restore.

  In step S505, the plug-in 105 determines whether the data (binary) 115 held in the QR code is only text data based on the QR code holding information (specifically, information 114) shown in FIG. Image data determination processing is performed to determine whether or not.

  As a result of the determination in step S505, if the data (binary) 115 held in the QR code is not only text data (for example, data including image data or the like), the process proceeds to step S506.

  In step S506, the plug-in 105 transmits to the server terminal device 700 for each page of the document to be restored based on the analysis result information held in the analysis result table 120 shown in FIG. 5 referred to in step S503. It is determined whether restoration is possible only from the stored electronic data.

  Specifically, this is performed based on the document presence / absence information 122 and the QR code restoration presence / absence information 123 held in the analysis result table 120 shown in FIG. The determination is made based on whether QROK (electronic data) is held.

  If restoration is possible only from electronic data, the process proceeds to step S516. If restoration is not possible only from electronic data, the process proceeds to step S507. Details of the processing in step S516 will be described later with reference to FIG.

  In step S507, the plug-in 105 reads information (FIG. 4) held in the QR code from the QR code holding the document data of the restoration target document.

  Subsequently, in step S508, the plug-in 105 performs document data restoration processing of the restoration target document based on the QR code information (specifically, data (binary) 115) read in step S506. . Thereafter, the process proceeds to step S512.

  On the other hand, as a result of the determination in step S505, if the data (binary) 115 held in the QR code is only text data, the process proceeds to step S509.

  In step S509, the plug-in 105 changes the restoration method to only text data according to the operation selection of the buttons (920, 921, 922) on the document restoration method selection screen 905 shown in FIG. 24 received in step S416. It is determined whether to restore, to copy from paper data, or to restore from electronic data.

  On the document restoration method selection screen 905, if QROK (electronic data) exists in the restoration information 123 with the QR code stored in the analysis result table 120 in step S407, the document analysis result indicates that. Is displayed on the document restoration method selection screen 905.

  As a result of the determination in step S509, when only text data is restored (when the restore text data only button 920 is selected on the document restoration method selection screen 905 shown in FIG. 24), the process proceeds to step S510.

  In step S510, the plug-in 105 reads the information (FIG. 4) held in the QR code from the QR code holding the document data (text data) of the restoration target document. Based on the QR code information (specifically, data 115), the document data (text data) of the document to be restored is restored.

On the other hand, as a result of the determination in step S509, when copying from paper data (when the copy button 921 is selected from paper data on the document restoration method selection screen 905 shown in FIG. 24), the process proceeds to step S511.
In step S511, the plug-in 105 performs a process of holding as print image data read from paper data. Thereafter, the process proceeds to step S515.

  On the other hand, as a result of the determination in step S509, when restoring from electronic data (when the restore button 922 from electronic data is selected on the document restoration method selection screen 905 shown in FIG. 24), the process proceeds to step S516.

  In step S516, the plug-in 105 performs processing for restoring a document from electronic data. Details of the processing in step S516 will be described later with reference to FIG.

  When the process of step S508 or step S510 is completed, subsequently, in step S512, the plug-in 105 operates the buttons (923, 924) on the QR code creation selection screen 906 shown in FIG. 25 received in step S418. It is determined whether or not to create a QR code according to the selection.

  As a result of the determination in step S512, when a QR code is not created (when the no button 924 is selected on the QR code creation selection screen 906 shown in FIG. 25), the process proceeds to step S515.

  On the other hand, if the result of determination in step S512 is to create a QR code (when the button 923 is selected for operation on the QR code creation selection screen 906 shown in FIG. 25), the process proceeds to step S513.

  In step S513, the plug-in 105 creates a QR code attached to the document data of the document to be restored, in the same manner as the QR code creation process shown in FIG.

  Subsequently, in step S514, the plug-in 105 places the QR code created in step S513 at a predetermined position of the document data restored in step S508 or step S510. Thereafter, the process proceeds to step S515.

  In step S515, the plug-in 105 determines whether there is a next page of the document to be restored. If the result of this determination is that there is a next page of the document to be restored, processing returns to step S503, and processing on the document to be restored of the next page is performed.

On the other hand, if the result of determination in step S515 is that there is no next page of the document to be restored, the processing of the flowchart shown in FIG. 18 ends (that is, processing in step S420 shown in FIG. 17 ends), and then The process proceeds to step S421 in FIG.
Next, the details of the restoration process for only the missing page in step S502 shown in FIG. 18 will be described with reference to FIG.

  When the process of step S502 in FIG. 18 is started, first, in step S601 in FIG. 19, the plug-in 105 refers to the analysis result table 120 shown in FIG. 5 for each page of the document to be restored.

  Subsequently, in step S602, the plug-in 105 deletes the page for each page of the document to be restored based on the analysis result information held in the analysis result table 120 shown in FIG. 5 referred to in step S601. It is determined whether or not.

  If the page is not missing as a result of the determination in step S602, the process proceeds to step S610. On the other hand, if the page is missing as a result of the determination in step S602, the process proceeds to step S603.

  In step S603, the plug-in 105 identifies a recoverable QR code from, for example, QR codes arranged on the pages before and after the missing page.

  Subsequently, in step S604, the plug-in 105 transmits to the server terminal device for each page of the document to be restored based on the analysis result information held in the analysis result table 120 shown in FIG. 5 referred to in step S601. It is determined whether restoration is possible only from the stored electronic data.

Specifically, this is performed based on the document presence / absence information 122 and the QR code restoration presence / absence information 123 held in the analysis result table 120 shown in FIG. Is determined by whether or not QROK (electronic data) is held.
If restoration is possible only from electronic data, the process proceeds to step S516. If restoration is not possible only from electronic data, the process proceeds to step S605.
In step S605, the plug-in 105 reads the information (FIG. 4) held in the QR code from the QR code specified in step S603.

  In step S606, the plug-in 105 performs document data restoration processing for the missing page based on the QR code information (specifically, data (binary) 115) read in step S605.

  Subsequently, in step S607, the plug-in 105 determines whether to create a QR code in response to the operation selection of the buttons (923, 924) on the QR code creation selection screen 906 shown in FIG. 25 accepted in step S418. Determine.

  As a result of the determination in step S607, if a QR code is not created (when the no button 924 is selected on the QR code creation selection screen 906 shown in FIG. 25), the process proceeds to step S610.

On the other hand, if the result of determination in step S607 is to create a QR code (when the button 923 is selected for operation on the QR code creation selection screen 906 shown in FIG. 25), the process proceeds to step S608.
When the processing proceeds to step S608, the plug-in 105 creates a QR code with the same purpose as the QR code creation process shown in FIG. 6 described above.

  Subsequently, in step S609, the plug-in 105 places and attaches the QR code created in step S608 at a predetermined position of the document data restored in step S606. Thereafter, the process proceeds to step S610.

In step S610, the plug-in 105 determines whether there is a next page of the document to be restored. If the result of this determination is that there is a next page of the document to be restored, the process returns to step S601 to perform processing on the document to be restored of the next page.
On the other hand, if the result of determination in step S610 is that there is no next page of the document to be restored, processing proceeds to step S611.

  In step S611, for example, the CPU 301 of the printer 300 uses the inserter 500 in response to the operation selection in the inserter use check box 919 received in step S414 in the document analysis result screen 904 shown in FIG. Determine whether or not.

  As a result of the determination in step S611, when the inserter 500 is used (when the inserter use check box 919 in the document analysis result screen 904 shown in FIG. 23 is checked), the process proceeds to step S612.

  In step S612, for example, the CPU 301 of the printer 300 creates a list instruction table for using the inserter function based on the analysis result table 120 shown in FIG.

  In this list instruction table, if the document presence / absence information 122 in the analysis result table 120 shown in FIG. 5 is “document”, the document is ejected from the inserter 500, and if it is “missing”, it is fed. The paper is set to be discharged from the paper cassette.

  It should be noted that, as shown in page number 3 of the analysis result table 120 shown in FIG. 5, for a document whose document presence / absence information 122 is “missing” and restoration information 123 with QR code is “QRNG”, the restoration Is impossible.

  Subsequently, in step S613, for example, the CPU 301 of the printer 300 performs a process of displaying an instruction screen 909 for setting a document on the inserter illustrated in FIG. 28 on the display screen 321 of the operation unit 320.

  After that, when the user presses the OK button 928 on the instruction screen 909 for setting a document on the inserter shown in FIG. 28, the CPU 301 of the printer 300, for example, in step S614, the list instruction table created in step S612. Is set in the inserter 500.

When the process of step S614 ends, or when it is determined in step S611 that the inserter 500 is not used, the process in the flowchart shown in FIG. 19 ends, and the process of step S502 shown in FIG. 18 ends. .
Next, details of the process of restoring from the electronic data in step S516 shown in FIG. 18 will be described using FIG.

  When the processing of step S516 in FIG. 18 is started, first, in step S701 in FIG. 29, the plug-in 105 is held in the QR code from the QR code holding the document data of the restoration target document. Read the information (Figure 4).

  Subsequently, in step S702, the plug-in 105 accesses the electronic data in the server terminal device 700 based on the QR code information (specifically, the file storage location 117) read in step S701.

  Subsequently, in step S703, the plug-in 105 compares the update date of the electronic data accessed in step S702 with the QR code information read in step S701 (specifically, the update date 118), and updates the electronic data. It is determined whether or not there was.

If the result of determination in step S703 is that electronic data has been updated, processing proceeds to step S706. In step S706, the plug-in 105 displays the result of step S703 on the update information confirmation screen (FIG. 30).
In step S707, the plug-in 105 selects whether to restore from the updated electronic data on the screen displayed in step S706.
If the result of determination in step S707 is to restore, or if the result of determination in step S703 is that there is no update of electronic data, processing proceeds to step S704.
Subsequently, in step S704, the plug-in 105 performs electronic data acquisition processing.
In step S705, the plug-in 105 performs a document restoration process from the electronic document data to be restored.
As a result of the determination in step S707, if not restored, the process proceeds to step S708.
In step S708, the plug-in 105 displays an end confirmation screen (FIG. 31).

  When the process of step S705 is completed, subsequently, in step S709, the plug-in 105 responds to the operation selection of the buttons (923, 924) on the QR code creation selection screen 906 shown in FIG. 25 received in step S418. To determine whether or not to create a QR code.

  As a result of the determination in step S709, if the QR code is not created (when the no button 924 is selected on the QR code creation selection screen 906 shown in FIG. 25), the process proceeds to step S515 and step S610.

  On the other hand, as a result of the determination in step S709, when a QR code is created (when the button 923 is selected for operation on the QR code creation selection screen 906 shown in FIG. 25), the process proceeds to step S710.

  In step S710, the plug-in 105 creates a QR code to be attached to the document data of the document to be restored, in the same manner as the QR code creation process shown in FIG.

If the update date of the restored document data has been changed (in the case of the flow from step S707), at the time of restoring the original document, a QR code is created with updated information about the current page and the previous and next pages, and the missing data When restoring only the page, not only the missing page but also the QR codes of the front and rear pages are created, and the QR code is arranged and attached to each page.

  Subsequently, in step S711, the plug-in 105 places and attaches the QR code created in step S710 at a predetermined position of the document data restored in step S705.

When the process of step S708 is completed or when the process of step S711 is completed, the process in the flowchart shown in FIG. 29 is finished, and the process of step S516 shown in FIG. 19 is finished.
As described above, the printer 300 and the document restoration system 100 that are document restoration apparatuses according to the present embodiment perform the following processing.
