  Further, from the viewpoint of printing an electronic document as a paper document by assigning a page ID to each page based on a print instruction (print job) from the client terminal 10, the image forming apparatus 30 has the composite shown in FIG. It is good also as a structure which has arrange | positioned not only the machine but the printer (one or more units) which has only a printing function.

  FIG. 5 is a block diagram showing a functional configuration of the policy management apparatus 40 in FIG.

  The policy management device 40 is composed of a general-purpose computer. As shown in FIG. 5, the policy management device 40 is a communication interface (I / F) unit 41 that controls a communication interface when communicating with the client terminal 10, the image forming device 30 and the like via the NW 60. And a storage unit 43 for storing various information such as operation programs and a control unit 45 for controlling the entire apparatus.

  In the policy management apparatus 40, the storage unit 43 is provided with a document authority information management table (TB) 431 and an authority information detail management table (TB) 433.

  In the document authority information management table 431, “document ID” indicating information for identifying a document and operation levels (operation levels 1, 2, 3,...) Permitted for the document having the document ID are displayed. The “operation authority” shown is retained.

  In the authority information detailed management table 433, “operation contents” indicating the contents of operations permitted by the authority are stored in correspondence with “operation authority”. As an example, the permitted operation content “view” is held for the operation level 1, and the permitted operation content “view” and “print” are held for the operation level 2. The permitted operation contents “view”, “scan”, “copy”, and “print” are held, and for operation level 4, the permitted operation contents “view”, “edit”, “scan”, “Copy” and “Print” are retained.

  In addition, the control unit 45 includes an authority information management unit 451 and an authority information search / distribution processing unit 453.

  The authority information management unit 451 registers and manages document authority information and authority information detailed information in the corresponding document authority information management table 431 and authority information detailed management table 433, respectively.

  The authority information search / distribution processing unit 453 cooperates with, for example, the document processing permission control unit 145 (see FIG. 2) of the client terminal 10 and the document processing permission control unit 368 (see FIG. 4) of the image forming apparatus 30. Upon receiving an authority inquiry request including a document ID from these apparatuses, document processing (“browse”, “print”, “scan”, “copy”, “copy” of the document corresponding to the document ID included in the authority inquiry request is received. Control is performed to distribute authority relating to “FAX transmission” to the inquiry source apparatus.

  As an example of document processing permission / inhibition control performed in cooperation with the policy management apparatus 40, for example, in the client terminal 10, a protected document [document for which authority (security policy) is set] managed by the document management apparatus 20 is used. When trying to access, an application is started by a user operation, and a protected document file in which a security policy is set is opened.

  At that time, in the client terminal 10, the user is authenticated by a predetermined method to obtain the user ID, and then the document processing permission / refusal control unit 145 is added to the protected document file (encrypted). The document ID and the user ID are transmitted to the policy management apparatus 40.

  On the other hand, when the policy management apparatus 40 receives the document ID and the user ID, the authority information search / distribution processing unit 453 sets the operation level set for the user associated with the received document ID to the document authority information. Based on the management table 431, the authority set for the user is checked from the authority information detailed management table 433 based on the operation level and notified to the document processing permission control unit 145 of the client terminal 10.

  On the other hand, in the client terminal 10, the document processing permission / refusal control unit 145 determines whether or not there is a viewing right based on the authority sent from the policy management apparatus 40. The decryption key sent with the authority from is decrypted with the decryption key, and the document is displayed on the screen.

  Thereafter, when the displayed electronic document (protected document) is printed (see the control sequence shown in FIG. 8), the policy management apparatus 40 is inquired about the authority using the document ID of the electronic document as a key, and the policy management apparatus After confirming that printing is permitted with reference to the authority transmitted as a response from 40, a print instruction (print job) is sent to the image forming apparatus 30 to print a paper document with a page ID.

  In addition, as an example of document processing permission / inhibition control performed in cooperation with the policy management device 40, the document processing permission / rejection control unit 368 of the image forming apparatus (multifunction peripheral) 30 performs the following processing when scanning the paper document in the reading unit 31. Control like this.

  Here, the paper document to be scanned is identified by the image corresponding to the electronic document of the page for each page by the image forming apparatus 30 such as a multifunction peripheral or a printer based on a print instruction from the client terminal 10. It is assumed that it is formed on a recording sheet together with an image of page ID.

  In the image forming apparatus 30, when the page ID is extracted by the page ID extraction unit 362 from the scan data obtained by scanning the paper document by the reading unit 31, the document processing permission control unit 368, based on the page ID. The document management apparatus 20 is inquired, the document ID of the printing source document held in correspondence with the page ID is acquired in the print document attribute management table 222, and the document ID is transmitted to the policy management apparatus 40.

  In the policy management apparatus 40, when the document ID is received, the authority information search / distribution processing unit 453 checks the operation level associated with the received document ID from the document authority information management table 431, and further sets the operation level to the operation level. Based on this, the authority is checked from the authority information detailed management table 433 and notified to the image forming apparatus 30.

  In the image forming apparatus 30, the document processing permission / refusal control unit 368 performs a user operation (start instruction operation such as scan, copy, FAX transmission, etc.) triggered by the current scan based on the authority sent from the policy management apparatus 40. It is checked whether or not there is an authority regarding the corresponding document processing (scanning, copying, FAX transmission, etc.), and if there is an authority, the document processing is instructed to the scan image processing unit 365 based on the scan data, for example. Control to execute.

  As described above, when the image forming apparatus 30 performs document processing based on the scan data obtained by scanning the image of the paper document, the page ID is extracted from the scan data, and the print source document is extracted based on the page ID. It is necessary to identify the document ID and confirm that there is a desired authority corresponding to the document ID.

  Here, due to the nature of the paper document to which the page ID handled by this system is assigned, scanning is started in a state where a plurality of paper documents are set at the reading position of the reading unit 31, and the reading unit 31 obtains the result of the scanning. It can happen that one or more page IDs are extracted from the scanned data.

  According to the image forming apparatus 30 of the present invention, even in such a case, the image forming apparatus 30 has an image processing function that can obtain a desired print (copy) result or scan result. Will be described in detail.

  In the first embodiment, in the system configuration shown in FIG. 1, the client terminal 10, the document management apparatus 20, the image forming apparatus 30, and the policy management apparatus 40 are respectively functional blocks shown in FIG. 2, FIG. 3, FIG. Consists of

  In the system of this embodiment, when the electronic document is printed by the image forming apparatus 30 as a paper document with a page ID, the document management apparatus 20 uses the document ID of the original electronic document, the page ID of each page, and the logic. While managing print document attribute information including page number and page size, the image forming apparatus 30 extracts a page ID from scan data obtained by the scan when scanning a paper document, and prints corresponding to the page ID. Print document attribute information (page size) of the original electronic document is acquired from the document management apparatus 20, and the scan data processing is executed on condition that the acquired page size matches the page size of the scan data. .

  Management of the electronic document and document attribute information in the document management apparatus 20 is based on a document registration process (see FIG. 6) from the client terminal 10 to the document management apparatus 20 and a print instruction from the client terminal 10 described below. This is realized through document printing processing (see FIG. 8) in the image forming apparatus 30.

  FIG. 6 is a diagram showing a control sequence between the client terminal 10 and the document management apparatus 20 related to document registration processing in the system of this embodiment.

  In the document registration process shown in FIG. 6, the client terminal 10 instructs the application unit 141 to start an application (document processing application) based on a predetermined user operation on the input / operation unit 11 (step S101), and edits it. A screen is displayed to accept input of information, and electronic document data is generated based on the input information (step S102).

  During the electronic document data generation processing, the document attribute information generation unit 144 monitors whether or not a document registration operation has been performed by the user using the input / operation unit 11 (step S103). If a registration operation has been performed (YES in step S103), For example, a document ID for identifying the electronic document data is generated by a method of allowing the user to input a desired document ID using the registration setting screen (step S104).

  In step S102, for example, processing for acquiring electronic document data registered in advance in the document management apparatus 20 or the like is allowed. If electronic document data is acquired from a registration destination, registration is performed in step S104. The document ID of the electronic document data may be acquired first.

  Next, the information registration / acquisition unit 142 registers the electronic document data generated (or acquired) in step S102 (step S105) and various data including the document ID generated (or acquired) in step S104 ( The process (step S106) of registering the metadata regarding the registration of the electronic document data is sequentially performed.

  In the electronic document data registration process in step S105, the information registration / acquisition unit 142 sends a registration request including the electronic document data to the document management apparatus 20 (step S105a).

  On the other hand, when the document management apparatus 20 receives the electronic document registration request sent from the client terminal 10 by the processing request reception unit 241, the information management unit 242 stores the electronic document data included in the registration request into, for example, a storage device 23 (step S201: electronic document registration process).

  In the electronic document metadata registration process in step S106, the information registration / acquisition unit 142 generates a document ID generated by the document attribute information generation unit 144 when generating the electronic document data and various metadata relating to the document registration. Is sent to the document management apparatus 20 (step S106a).

  On the other hand, when the electronic document metadata registration request sent from the client terminal 10 is received by the processing request reception unit 241 in the document management device 20, the information management unit 242 causes the document ID included in the registration request and the above-described step S201. For example, the electronic document data is stored in the registered document attribute management table 221 of the storage unit 22 in association with the storage location of the electronic document data (step S202: electronic document metadata registration processing).

  FIG. 7 is a diagram illustrating an example of information registered in the registered document attribute management table 221 of the document management apparatus 20.

  In the registered document attribute management table 221 of this example, the document ID (= docu1) of the document 1 stored in the storage device 23, the storage location (= ftp: // xxxx) of the document 1 in the storage device 23, and the storage device The document ID (= docu2) of the document 2 stored in 23 and the storage location (= ftp: // yyyyy) of the document 2 in the storage device 23 are stored in association with each other.

  In the example of FIG. 7, the registered document attribute management table 221 clearly indicates that only the storage location of the electronic document data having the document ID corresponding to the document ID is registered. You may make it store metadata, such as a creator of this electronic document data, and creation date.

  FIG. 8 is a diagram illustrating a control sequence among the client terminal 10, the document management apparatus 20, and the image forming apparatus 30 related to the electronic document printing process in the system of this embodiment.

  In the electronic document printing process shown in FIG. 8, for example, the client terminal 10 starts an application by a process similar to step S101 in FIG. 6 (step S121), and further performs an electronic document by a process similar to step S102 in FIG. Data is generated or acquired (step S122).

  During the electronic document data generation processing, the document attribute information generation unit 144 monitors whether or not the user has performed a print start operation using the input / operation unit 11 (step S123), and when the print start operation is performed (step S123). In step S123, a document ID for identifying the electronic document (printing source electronic document) is generated (step S124).

  The document ID of the printing source electronic document can be generated in the same process as in step S104 in FIG. 6, and when the electronic document data is acquired from the registration destination, the document ID can also be acquired.

  Subsequently, the document attribute information generation unit 144 analyzes the electronic document data of the printing source, and each of the logical page number of each page of the electronic document data, the page ID of each page, and the page size of each page. Information is generated (step S125).

  For this page ID, for example, a hash value is calculated based on the electronic document data of each page of the printing source electronic document, and the hash value is generated as the page ID of the corresponding page.

  Next, the print job generation unit 142 generates a print job from the electronic document data generated (or acquired) in step S122 and the page ID generated in step S125 (step S126).

  Here, the print job generation unit 142 draws the electronic document data of each page of the printing source with a page ID corresponding to each page, and more specifically, for each page. Then, a print job in which an instruction to draw electronic document data and a QR code corresponding to a hash value calculated as a page ID based on the electronic document data of the page is generated is generated.

  After generating the print job, the information registration / acquisition unit 142 generates the document ID of the electronic document that is generated (or acquired) in step S124 and the logical page number and page ID of each page generated in step S125. And the process (step S127) which each information of page size is matched and registered is implemented.

  In this print document attribute information registration process, the information registration / acquisition unit 142 includes information on the document ID of the print source electronic document, the logical page number of each page of the print source electronic document, the page ID, and the page size. A registration request is sent to the document management apparatus 20 (step S127a).

  On the other hand, when the document management apparatus 20 receives the print document attribute registration request sent from the client terminal 10 by the processing request reception unit 241, the information management unit 242 causes the document ID included in the registration request and the logical page of each page. Each information of the number, page ID, and page size is extracted individually, and these pieces of information are associated with each other and stored in, for example, the print document attribute management table 222 of the storage unit 22 (step S211: print document attribute, meta data). Data registration process).

  Thereafter, the print job generation unit 143 performs print instruction processing for transmitting the print job generated in step S126 to the image forming apparatus 30 via the NW 60 via the communication I / F unit 15 (step S128).

  In contrast, when the image forming apparatus 30 receives the print job sent from the client terminal 10 via the communication I / F unit 37, the print control unit 361 prints a paper document based on the print job (step S301). Execute.

  In this paper document printing process, the print control unit 361 analyzes the drawing command in the received print job, and the image processing unit 32 converts the electronic document data into each page according to the analysis result. Print image data that can be drawn together with a QR code indicating the corresponding page ID is generated, and the image forming unit 34 generates an image of the electronic document data of the page and the page for each page based on the print image data. Are printed out as a number of paper documents corresponding to the number of pages on which a QR code image corresponding to the page ID is formed.

  FIG. 9 is a conceptual diagram showing an example of a paper document print output by the image forming apparatus 30 in step S301 of FIG.

  9A shows an output example of the document 1 with the document ID “docu001” composed of 3 pages of A4 size, and FIG. 9B shows the document composed of 2 pages of A4 size. It is an output example of the document 2 whose ID is docu002.

  As shown in FIG. 9A, when the user gives a print instruction for the document 1 from the client terminal 10, the image forming apparatus 30 that has received a print job based on the print instruction starts with the electronic data for the first page. A paper document 3401 of the first page on which an image corresponding to document data (= what it is) and an image corresponding to the page ID (= P0011) corresponding to the first page is formed is output, and then the second page A paper document 3402 of the second page in which an image corresponding to electronic document data (= Kakikaku) and an image corresponding to the page ID (= P0012) corresponding to the second page is formed is output, and further three pages Finished outputting the paper document 3403 for the third page in which the image corresponding to the electronic document data for the eye (= the insert) and the image corresponding to the page ID corresponding to the third page (= P0013) are formed. Thereafter, the printing operation is terminated.

  Further, according to FIG. 9B, when a print instruction for the document 2 is issued from the client terminal 10, the image forming apparatus 30 that has received a print job based on the print instruction starts with the electronic document data for the first page. Is output as a first page paper document 3411 in which an image corresponding to the first page (= hahifu) and an image corresponding to the page ID (= P0021) corresponding to the first page are formed. After the output of the paper document 3412 of the second page in which the image corresponding to the electronic document data (= Mamimu) and the image corresponding to the page ID (= P0022) corresponding to the second page is formed, the printing is performed. End the operation.

  As illustrated in FIG. 9, when the document 1 and the document 2 are printed and output as a paper document with a page ID assigned to each page by the image forming apparatus 30 according to a print instruction from the client terminal 10, the document management apparatus 20. Then, the print document attribute information regarding the documents 1 and 2 is held in the print document attribute management table 222 by the print document attribute and metadata registration process in step S211 of FIG.

  FIG. 10 is a table showing an example of information held in the print document attribute management table 222 of the document management apparatus 20.

  In FIG. 10, when the electronic document 1 is printed, the page ID (P0011, P0012, P0013) of each page 1 to 3 of the document 1, the logical page number (1, 2, 3) of each page, The page size (A4) is stored in correspondence with the document ID (docu001) of the printing source electronic document 1.

  Similarly, when the electronic document 2 is printed, the page ID (P0021, P0022) of each page 1, 2 of the document 2, the logical page number (1, 2) of each page, and the size (A4) of each page. ) Is held in correspondence with the document ID (docu002) of the printing source electronic document 1.

  Here, the document ID held in the print document attribute management table 222 is linked to the document ID held in the registered document attribute management table 221, and if the page ID registered in the print document attribute management table 222 is known, Through the link from the document ID in the table 222 corresponding to the page ID to the document ID having the same value in the registered document attribute management table 221, the storage location of the electronic document data of the printing source corresponding to the document ID can be understood. It has become.

  Next, a processing operation when a paper document printed in the mode shown in FIG. 9 is scanned by the reading unit 31 of the image forming apparatus 30 will be described.

  FIG. 11 is a diagram showing a control sequence between the image forming apparatus 30 and the document management apparatus 20 related to the paper document scan processing operation of the present embodiment.

  When scanning a paper document in the image forming apparatus 30, the user sets the paper document at a predetermined reading position corresponding to the size of the paper document on the platen, and then performs a scan start operation on the display / operation unit 35. Do.

  In the image forming apparatus 30, during standby, the control unit 36 monitors whether or not a scan start operation has been performed (step S311). When the scan start operation has been performed (step S311 YES), the reading unit 31 is driven. Then, the image of the paper document set on the platen is scanned (step S312), and the scan data obtained by the scan is temporarily captured in, for example, the storage unit 33 (step S313).

  After the start of the scanning operation, the control unit 36 monitors whether or not the scanning operation is completed (step S314). When the scanning operation is completed (step S314 YES), the control unit 36 instructs the page ID extraction unit 362 to that effect. Accordingly, the page ID extraction unit 362 extracts the page ID based on the scan data corresponding to the page ID in the scan data obtained so far (step S315).

  Further, the control unit 36 activates the scan page size recognition unit 363, whereby the scan page size recognition unit 363 recognizes the page size of the scan data based on the scan data (step S316).

  Next, the information acquisition unit 364 accesses the document management apparatus 20 using the page ID extracted by the page ID extraction unit 362 as a key, and the print document held in the print document attribute management table 222 corresponding to the page ID. Attribute information (document ID, logical page number, page size information of the electronic document to be printed) is acquired (step S317).

  In the process of step S317, in the image forming apparatus 30, the information acquisition unit 364 sends a document attribute acquisition request including the page ID to the document management apparatus 20 (step S317a).

  On the other hand, in the document management apparatus 20, when the document attribute acquisition request sent by the image forming apparatus 30 is received by the processing request reception unit 241, the information search distribution processing unit 243 uses the page ID included in the registration request as a key. Then, each information of the document ID corresponding to the page ID, the logical page number of each page, and the page size is retrieved from the print document attribute management table 222, and an acquisition request response signal including these pieces of information is formed as an image request source image. The information is transmitted to the device 30 (step S221: information search / distribution process).

  On the other hand, in the image forming apparatus 30, the information acquisition unit 364 captures a response signal sent from the document management apparatus 20 in response to the document attribute acquisition request, and acquires each piece of information included in the response signal.

  When the information acquisition unit 364 acquires the document ID, page number, and page size information of the printing source document corresponding to the page ID extracted by the page ID extraction unit 362, the scan image processing unit 365 continues to acquire the document ID. The page size indicated by the page size information of the printing source electronic document in the information acquired from the management apparatus 20 is compared with the page size of the scan data recognized by the scan page size recognition unit 363 in step S316 (step S318). It is determined whether or not the respective sizes match (step S319).

  If it is determined that the page sizes match (YES in step S319), the scan image processing unit 365 performs image processing in the next step on the scan data temporarily stored in the storage unit 33 (step S319). S341), after completion of the image processing, transition to a standby state.

  In step 341, the scan image processing unit 365 responds to the operation using the document ID acquired in step S317 as a key in accordance with the content of the scan start operation (operation such as scan, copy, FAX transmission, etc.) in step 311. The document processing (scanning, copying, FAX transmission, etc.) is executed when it is recognized that there is an authority.

  On the other hand, when it is determined in step S319 that the page size of the electronic document to be printed does not match the page size of the scan data (NO in step S319), the scan image processing unit 365 temporarily stores in the storage unit 33. After the stored scan data is deleted (step S331), an error message indicating an input data error is displayed (step S332), the user is notified of the abnormality, and then the process returns to the standby state to return to the next paper document. Accept scans.

  Next, a specific example of the series of paper document scan processing operations shown in FIG. 11 will be described with reference to FIG.

  In FIG. 12, the paper document 3402 (paper document a) of the second page of the three-page paper document [see FIG. 9A] obtained by printing the document 1 and the document 2 are printed. When scanning the paper document 3411 (paper document b) of the first page of the obtained two-page paper document (see FIG. 9B) on the platen of the image forming apparatus 30 at once. An example is shown.

  Here, the paper document 3402 and the paper document 3411 to be scanned are both of A4 size, and these two paper documents 3402 and 3411 are placed at the A3 size reading position on the platen in the manner shown in FIG. Set.

  In this set state, when an image scan of the paper document in the sub-scanning direction (y direction) is performed line by line in the main scanning direction (x direction) from the position L1 in FIG. 12, and the scanning to the position L2 is completed. Scan data corresponding to the A3 size paper document is obtained by combining the paper documents 3402 and 3411.

  Then, based on the scan data, the page ID extraction unit 362 uses the page ID = P0012 assigned to the paper document 3402 based on, for example, the page ID area data of the paper document 3402 in the scan data. Extract (see step S315 in FIG. 12).

  The scan page size recognition unit 363 recognizes the page size of the scan data = A3 based on the scan data (see step S316).

  Subsequently, the information acquisition unit 364 uses the page ID = P0012 of the paper document 3402 extracted by the page ID extraction unit 362 as a key from the print document attribute management table 222 (see FIG. 10) held in the document management apparatus 20. The page size = A4 of the print source electronic document 1 (document ID = docu001) corresponding to the page ID = P0012 is acquired (see step S317).

  Further, the scan image processing unit 365 compares the page size = A3 recognized from the scan data with the page size = A4 acquired from the document management apparatus 20 and determines that the two page sizes do not match (step S1 in FIG. 2). (Refer to S319NO).

  If the determination result is obtained, the scan data of the paper documents 3402 and 3411 is deleted, and an error message is displayed (see steps S331 and 332).

  Similarly, when the page ID = P0021 of the paper document 3411 is extracted in step S315, the print document attribute management table 222 (see FIG. 10) held in the document management apparatus 20 using the page ID = P0021 as a key. ), The page size = A4 of the electronic document 2 (document ID = docu002) corresponding to the page ID = P0021 is acquired, and the acquired page size = A4 and the page size recognized from the scan data = A3. Based on the determination result that they do not match, the scan data is deleted and an error message is displayed.

  Here, as an error message for anomaly notification, for example, a message with the content “The page size read is different from the page size of the original document” is displayed, and a paper document is displayed to the user who viewed the error message. It is possible to take measures such as prompting to scan by setting 3402 and 3411 separately.

  In the second embodiment, in the system configuration shown in FIG. 1, the client terminal 10, the document management device 20, and the policy management device 40 are configured by the functional blocks of FIGS. 2, 3, and 5, respectively, as in the first embodiment. The

  As illustrated in FIG. 13, the image forming apparatus 30 </ b> B according to the present exemplary embodiment includes a control unit 36 that includes a print control unit 361, a page ID extraction unit 362, a scan page size recognition unit 363, and an information acquisition unit that are the same as those in the first exemplary embodiment. 364, a document processing permission / refusal control unit 368, and a page ID extraction determination unit 366 and a multi-page image processing unit 367 as functional blocks not provided in the first embodiment.

  The page ID extraction determination unit 366 includes the page size acquired from the document management apparatus 20 by the information acquisition unit 364 based on the page ID extracted by the page ID extraction unit 362 from the scan data obtained by scanning the paper document, and the scan. If the page size of the scan data recognized by the page size recognition unit 363 is different, the page ID extraction unit 362 determines whether another page ID is extracted from the scan data.

  When the page ID extraction determination unit 366 determines that another page ID has been extracted from the scan data, the multiple page image processing unit 367 processes the scan data as scan data of a plurality of pages.

  Next, the operation of the system according to the present embodiment will be described.

  FIG. 14 is a diagram showing a control sequence between the image forming apparatus 30 and the document management apparatus 20 related to the paper document scan processing operation of this embodiment.

  In FIG. 14, the same processing steps as those in the paper document scanning process in the first embodiment shown in FIG.

  In FIG. 14, the processes in steps S311 to S319, S331, S332, and S341 are the same as those in the first embodiment, and the processes in steps S321 to S323 are unique to the present embodiment.

  In the image forming apparatus 30B according to the present exemplary embodiment, when a scan start operation is performed after setting a paper document to be scanned in the series of processing in steps S311 to S319 in FIG. 14 (YES in step S311), the paper is read by the reading unit 31. The document is scanned (step S312), the scan data is captured (step S313), and when the scanning operation ends (YES in step S314), the page ID extraction unit 362 extracts the page ID from the scan data (step S315). On the other hand, the scan page size recognition unit 363 recognizes the page size of the scan data (step S316), and the information acquisition unit 364 uses the page ID extracted in step S315 as a key to print the page size of the electronic document to be printed. Is acquired from the document management apparatus 20 (step 317).

  Next, the multi-page image processing unit 367 compares the page ID of the printing source electronic document acquired by the information acquisition unit 364 with the page size of the scan data recognized by the scan page size recognition unit 363 (step S318). It is determined whether or not the page sizes match (step S319).

  If it is determined that the sizes match (YES in step S319), the multi-page image processing unit 367 performs image processing (scanning and copying) for the next process on the scan data temporarily stored in the storage unit 33. , FAX transmission, etc.) (step S341), and after the image processing is completed, transition to a standby state.

  On the other hand, when it is determined in step S319 that the page ID of the electronic document as the printing source does not match the page size of the scan data (NO in step S319), the page ID extraction determination unit 366 performs the process in step S315. For the page ID extraction result by the page ID extraction unit 362, a search is made for a page ID different from the page ID for which the page size of the scan data is compared in step S318 (step S321). Is extracted by the page ID extraction unit 362 (step S322).

  If it is determined that a page ID different from the page ID for which the page size of the scan data is to be compared has not been extracted (NO in step S322), the multiple page image processing unit 367 temporarily stores the page ID in the storage unit 33. Deletes the stored scan data (step S331), displays an error message indicating an input data error (step S332), informs the user of the abnormality, returns to the standby state, and then returns to the next state. Accept scanning of paper documents.

  On the other hand, if it is determined that a page ID different from the page ID for which the page size of the scan data is to be compared is extracted (NO in step S322), the multiple page image processing unit 367 performs the above steps S312 and S3. A plurality of scan data obtained by the scan in S313 corresponding to the number of all the page IDs extracted by the page ID extraction unit 362 (including the page IDs to be compared with the page size of the scan data in Step S318). A multi-page process is performed (step S323), and after the multi-page process is completed, image processing (scanning, copying, FAX transmission, etc.) of the next process is performed on the multi-page scan data. This is performed (step S341).

  FIG. 15 is a diagram showing a control sequence between the image forming apparatus 30 and the document management apparatus 20 related to the multi-page processing in step S323 of FIG.

  As shown in FIG. 15, the image forming apparatus 30 determines that a page ID different from the page ID compared with the page size of the scan data has been extracted in step S322 of FIG. 14 (NO in step S322). When the process proceeds to the multi-page processing (step S323), first, the multi-page image processing unit 367 instructs the information acquisition unit 364 to extract each of these pages extracted from the scan data as in step S317 of FIG. The document management apparatus 20 is accessed using the ID (however, excluding the page ID to be compared in step S313) as a key, and the print document attribute information (document ID and page of the printing source document) corresponding to each page ID. Number and page size information) is acquired (step S351).

  Next, the multi-page image processing unit 367 extracts the page size information of the printing source electronic document corresponding to each page ID from the respective print document attribute information acquired using each page ID as a key, and extracts the page size information. Further, based on the page size of each print source electronic document, the scan data is divided into areas of each page size (step S353), and the scan data of each divided area is temporarily stored in, for example, a storage unit 33 (step S354).

  Here, for example, if the page size of the scan data is A4, and the page size of each printing source document corresponding to, for example, two different page IDs extracted from the scan data is A4, the page size of A3 is set. The scan data is divided into two A4 size areas.

  Subsequently, the multi-page image processing unit 367 generates a document ID for identifying each area of the scan data stored in the storage unit 33 as a scanned electronic document (image data) (step S355).

  Thereafter, the multi-page image processing unit 367 generates each document ID generated (or acquired) in step S355 and the scan data (scan electronic data) of each region corresponding to each document ID obtained by the region division in step S353. Document data) is associated with each other and registered in the document management apparatus 20 (step S356), and processing for registering metadata relating to the registration of the scanned electronic document data (step S357) is sequentially performed. After the registration of the scanned electronic document data and its metadata to the document management apparatus 20 is completed, the multi-page process (step S323) is exited, and the process proceeds to the next scan data processing step (step S341 in FIG. 14).

  The scan electronic document data (image data of each divided region) registration process in step S356 and the metadata registration process in step S357 are performed on the image forming apparatus 30 side, for example, in FIG. Can perform the same procedure as when performing processing for registering an electronic document in the document management apparatus 20 and when performing processing for registering the electronic document metadata.

  However, in the case of this scanned electronic document data and its metadata registration, the document management apparatus 20 side receives a registration request including each document ID and scanned electronic document data corresponding to each document ID from the image forming apparatus 30. The information management unit 242 stores each scanned electronic document data (image data of each divided area) included in the document registration request in a predetermined storage location (scanned electronic document data registration area) of the storage device 23, and The storage location and each page ID are stored in association with each other (step S201a). On the other hand, when a metadata registration request regarding registration of the scanned electronic document data is continuously received from the image forming apparatus 30, it is included in the metadata registration request. Scanned electronic document metadata by associating each document ID with document attribute information such as creation date and time corresponding to each document ID Registered in the scanned document attribute management table 223 as (step S202a).

  Next, a specific example of the series of paper document scan processing operations shown in FIGS. 14 and 15 will be described with reference to FIG.

  Also in FIG. 16, the paper document 3402 (paper document a) of the second page of the three-page paper document [see FIG. 9 (a)] obtained by printing the document 1 and the document as in FIG. The paper document 3411 (paper document b) of the first page of the two-page paper document obtained by printing 2 (see FIG. 9B) is set on the platen of the image forming apparatus 30. This assumes that you are scanning at once.

  In this case, the process flow up to steps S315, S316, S317, and S319NO shown in FIG. 16 is the same as that in the scan process shown in FIG.

  However, in this embodiment, in step S319, the page size of the scan data = A3 and the page size of the electronic document 1 of the printing source acquired from the document management apparatus 20 based on the page ID = P0012 extracted from the scan data = A4. Is determined not to match (NO in step S319), the page ID extraction determination unit 366 searches for the page ID = P0021 different from the page ID = P0012 from the page ID extraction result in step S315 (FIG. 16). (See YES in step S322).

  Next, the multi-page image processing unit 367 proceeds to multi-page processing (see step S323), and uses the information acquisition unit 364 to print the electronic data of the printing source from the document management apparatus 20 using the page ID = P0021 as a key. The page size of the first page of document 2 = A4 is acquired (see step S351).

  Further, the multi-page image processing unit 367 prints the page size A4 of the second page of the electronic document 1 that has already been acquired using the page ID = P0012 as a key, and then the page ID = P0021 as a key. Based on the page size A4 of the first page of the original electronic document 2, scan data having a page size of A3 is divided into two areas of A4 size (see step S353).

  Then, the scan data of each divided area is used as scan data of the paper document a printed on the second page of the electronic document 1 and scan data of the paper document b printed on the first page of the electronic document 2, respectively. After the storage, the document ID corresponding to each is registered in the document management apparatus 20 (see steps S354 to S357).

  FIG. 17 is a conceptual diagram showing a specific example of the area division process of scan data in steps S351 and S353 in the specific example illustrated in FIG.

  In this area division processing, the image forming apparatus 30 first corresponds to the page size = A4 of the printing source document 1 corresponding to the page ID = P0012 and another page ID = P0021 as shown in FIG. The page size = A4 of the printing source document 2 to be acquired is acquired (corresponding to step SS351 (and S317 in FIG. 16)).

  Next, as shown in FIG. 17B, the multi-page image processing unit 367 sets the page size of the printing source document 1 = A4, the page size of the printing source document 2 = A4, and the page size of the scan data = A3. Based on the above, an image area that can divide the A3 size image area of the scan data into two A4 size images is determined.

  After that, as shown in FIG. 17C, the multi-page image processing unit 367 converts the A3 size scan data into the A4 size first image region according to the determination of the divided image region in FIG. Similarly, it is divided into two A4 size second image areas, and one scan data corresponding to the scan data of the paper document a and another scan data corresponding to the scan data of the paper document b are generated [FIG. 17 (b), (c): Corresponds to step S353 in FIG.

  An image forming apparatus 30C (not shown) according to the third embodiment modifies the multi-page processing function of the multi-page image processing unit 367 provided in the control unit 36 of the image forming apparatus 30B (see FIG. 13) according to the second embodiment. The configuration of each functional block other than the multi-page image processing execution unit (referred to as 367c for convenience) having the modified multi-page processing function is the same as that of the image forming apparatus 30B according to the second embodiment. is there.

  In the image forming apparatus 30C according to the present embodiment, the paper document is scanned along the flow shown in FIG. 14 as in the case of the image forming apparatus 30B according to the second embodiment. However, in the multi-page process of step S323 in FIG. The multi-page image processing unit 367c includes not only the page size information of each electronic document of the printing source respectively corresponding to the plurality of page IDs extracted from the scan data, but also the image of the electronic document of each printing source (for each page ID). Electronic document data of the corresponding page) is also acquired from the document management apparatus 20, and the scan data is divided into regions based on the acquired page size information of the electronic document of each printing source and the image of each page. It has a function to process as an image.

  The multi-page process (referred to as step S323c for convenience) in the image forming apparatus 30C according to the present embodiment will be described with reference to the control sequence shown in FIG.

  In FIG. 18, the same reference numerals are assigned to the same processing steps as those in the multiple page processing (see FIG. 15) in the image forming apparatus 30B according to the second embodiment.

  In the image forming apparatus 30C of the present embodiment, in this multi-page process (step S323c), a page ID different from the page ID that is the comparison target of the page size of the scan data in step S322 of FIG. 14 is extracted. Is started by the page ID extraction determination unit 366 (NO in step S322).

  When the process proceeds to the multi-page processing (step S323c), first, the multi-page image processing unit 367c instructs the information acquisition unit 364, and each page ID extracted from the scan data (however, as in step S317 in FIG. The document management apparatus 20 is accessed with the key of “excluding the page ID to be compared in step S318” as a key, and the print document attribute information (document ID, page number, page of the original document) corresponding to each page ID. Each information of size) is acquired (step S351).

  In addition, the multi-page image processing unit 367c continues to instruct the information acquisition unit 364 to specify the document ID of each electronic document of the printing source corresponding to each page ID acquired in step S351 and each page ID. The document management apparatus 20 is accessed using each corresponding page number as a key, and image data (electronic document data) of the page number of the printing source electronic document stored in the storage device 23 corresponding to each document ID. Is acquired (step S352).

  In this image data acquisition process, the image forming apparatus 30C gives the document management apparatus 20 a document acquisition including the combination of the document ID and page number acquired in step S351 for each page ID extracted from the scan data. On the other hand, in the document management apparatus 20, when the processing request processing unit 241 receives the document acquisition request, the information search / distribution processing unit 243 sets the document ID and page number of each set included in the document acquisition request. For each set, the storage location of the electronic document of the printing source corresponding to the document ID is specified for each group, and the image data of the page corresponding to the page number is read from the storage location of the storage device 23, and the image forming apparatus It transmits to 30C (step S223).

  In step S351, page size information of each printing source electronic document corresponding to each page ID extracted from the scan data is acquired, and in step S352, corresponding to each page ID extracted from the scan data. When the image data of the corresponding page of the electronic document of the printing source is acquired, the multi-page image processing unit 367c scans the data based on the page size of each electronic document of the printing source and the image data of the corresponding page. Is divided into a plurality of areas (the number of each page) having the image content and page size of each page (step S353a), and the scan data of each divided area is temporarily stored in, for example, the storage unit 33. Store (step S354).

  After that, the multi-page image processing unit 367c attaches the document ID to each area of the scan data (scan electronic document data) stored in the storage unit 33 as in the multi-page process (see FIG. 15) of the second embodiment. After registering in the management apparatus 20 and registering electronic document metadata relating to this processing (steps S355 to S357), the multi-page processing (step S323c) is exited, and the next scan data processing step (FIG. 14) is performed. The process proceeds to step S341).

  FIG. 19 is a conceptual diagram showing a specific example of area division processing of scan data in steps S351 to S353a of FIG.

  Also for this processing, for example, as shown in FIG. 16, a paper document 3402 (paper document a) on which the second page of document 1 is printed and a paper document 3411 (paper document on which the first page of document 2 is printed). b) is scanned at one time. Of the page IDs = P0012 and P0021 extracted from the scan data at this time, the page size = A4 corresponding to the page ID = P0012 is obtained based on the page ID = P0012, and the page ID = P0012 is obtained. A process is assumed after it is determined that another page ID = P0021 is extracted after it is determined that the page size of the scan data does not match A3.

  In the scan data area division processing (see FIG. 19) performed thereafter, the image forming apparatus 30C firstly, as shown in FIG. 19A, the page size of the printing source document 1 corresponding to the page ID = P0012. = A4 and the image data “Kakiku” of the second page and the page size of the original document 2 corresponding to another page ID = P0021 = A4 and the image data “Hahifu” of the first page are acquired. (Corresponding to steps S351 and S352 in FIG. 18).

Next, as shown in FIG. 19B, the multi-page image processing unit 367c starts from the image content “Aki” in the A4 size from the page size = A4 of the printing source document 1 and the image data of the second page. The first collation image data is generated, while the page size of the printing source document 2 is A4 and the image data of the first page is the second collation image having an image content of A4 size “hahifu”. Next, as shown in FIG. 19C, the multi-page image processing unit 367c analyzes the scan data and collates the scan data with the first and second collation image data. Then, from the scan data, the first image area in which the page size and the image content “scratch” coincide with the first comparison image data, the second comparison image data, the page size and the image content. “Hahif” matches 2 image areas are specified.

  After that, as shown in FIG. 19D, the multi-page image processing unit 367c converts the A3 size scan data into the first image area (A4 size “scratch” image specified in FIG. 19C). Area) and a second image area (an image area of A4 size “hahifu”), and is divided into one scan data corresponding to the scan data of the paper document a and scan data of the paper document b. Another corresponding scan data is generated (FIGS. 19B to 19C: corresponding to step S353a in FIG. 18).

  In FIG. 19C, as the scan data to be divided into regions, the paper document a and the paper document image are set in positions opposite to each other, and the paper document b is set at a position to be scanned first. The scan data is shown as an example.

  However, in this embodiment, as shown in FIG. 19, the page size (A4, A4) of the electronic document of the printing source corresponding to each paper document a, b to be scanned and the image data of the corresponding page [“Kakiku” , “Hahif”], the area of the scan data is divided, so that regardless of the orientation (setting direction) of the images of the paper documents a and b set at the reading position, and in the order of scanning. Regardless, scan data corresponding to the paper documents a and b can be divided and generated from the scan data obtained by scanning the paper documents a and b.
