<1-5. Outline of operation>
In the following, a workflow as shown in FIG. 4, that is, an approval process (stamping process) by three users UA, UB, and UC (for example, a section manager, a department manager, and a president, respectively) for a certain document (specifically, an electronic document DE). ) Is exemplified. In this workflow, the users UA, UB, and UC sequentially perform approval processing (stamping processing) for the electronic document DE.

  As described above, the server 50 stores a plurality of documents, specifically, the electronic documents DE (DE1, DE2, DE3,... (See FIG. 1)) in the storage unit 55, and the plurality of documents. The document data table TB1 (FIG. 14) is also stored in the storage unit 55. In the data table TB1, the association between the document ID (document identification information) and the stamp information is stored for each electronic document DE. Specifically, the document ID, the document data file name, the document type, and the stamp information of the three stamp fields are stored in association with each other. At this point, the document ID (for example, “001”), the document data file name (for example, “planning document.doc”), and the document type (“in-house document”) are recorded for the target document DE for the stamping process. Yes. On the other hand, it is assumed that the stamp information is not yet recorded in the three stamp fields related to the target document DE.

  First, a certain document (in detail, electronic document DE) of the plurality of documents is printed out by the MFP 10 (time T11).

  Specifically, the MFP 10 receives a print output operation by the operating user. During the operation, a list screen (not shown) of print output target documents is displayed on the display unit 6b of the MFP 10. In the list screen, one or more document names including the target document DE are listed. The operating user selects a desired electronic document DE (DE1) as a print output target file from the list screen. When the print output target file is designated (determined), the MFP 10 communicates with the server 50 to obtain the file data of the electronic document DE designated as the print output target file and the document ID that is identification information of the electronic document DE. Receive information including.

  The MFP (image forming apparatus) 10 prints out the electronic document DE based on the file data of the electronic document DE, and generates a paper document DP (printed output of the electronic document) corresponding to the electronic document DE ( (See FIG. 5). In this printout, an identification image GD (for example, a two-dimensional barcode image) including a document ID that is identification information of the electronic document DE to be output is generated, and the identification image GD is generated for the electronic document DE. It is added and printed out as a paper document DP. The identification image GD preferably includes not only “document ID” but also information related to “page number” of each page. In addition, although a two-dimensional barcode image is illustrated here as the identification image GD, it is not limited to this. For example, another barcode image such as a one-dimensional barcode may be used as the identification image GD. Alternatively, other images such as a copy-forgery-inhibited pattern image may be used as the identification image GD.

  In this way, the paper document DP corresponding to the electronic document DE (DE1) is generated. Here, it is assumed that three users UA, UB, and UC each have one paper document DP (DPa, DPb, DPc). Each user UA, UB, UC can check the content of the document (in real space) using the paper document DP (DPa, DPb, DPc). In other words, the paper document DP (DPa, DPb, DPc) is a printed output for browsing (for confirmation) related to a document to be approved by an approved user (UA, UB, UC). However, at this time, as shown in FIG. 5, each paper document DP (specifically, the respective stamp fields SC1, SC2, SC3) is not yet stamped. In the blank area of the paper document DP (here, the lower right portion in the paper document DP), an identification image GD is added and printed out. Here, the case where each user UA, UB, and UC confirms the contents of the document by using individual paper documents DPa, DPb, and DPc is illustrated, but the present invention is not limited to this. For example, each user UA, UB, UC may check the contents of the electronic document DE using the same (single) paper document DP (for example, DPa).

  Thereafter, the operation as shown in FIG. 6 is repeatedly executed for a plurality of users UA, UB, and UC.

  First, the approval process regarding the user UA (section manager) who is the first approver will be described with reference to FIGS.

  The user UA captures a paper document DP including the identification image GD using the mobile terminal 70a (step S11). Specifically, in response to the shooting operation of the user UA, the mobile terminal 70a uses the imaging unit 73 to capture a paper document DP and obtains a captured image GC (GCa) related to the paper document DP.

  The portable terminal 70a extracts the document ID included in the identification image GD in the captured image GCa from the identification image GD, and transmits the extracted document ID to the server 50 (step S12).

  The server 50 refers to the data table TB1 (FIG. 14), specifies the approval target document DE1 (“planning document.doc”) based on the document ID transmitted from the portable terminal 70, and associates it with the document ID. Also obtain the stamp information. Then, the server 50 transmits the acquired stamp information to the portable terminal 70a as superimposed display information (step S13).

  On the other hand, the portable terminal 70a displays the photographed image GC of the paper output document DP corresponding to the electronic document DE on the display unit 72 (touch screen 71S), and displays the stamp information transmitted from the server 50 in the photographed image. The image is displayed superimposed on the GC (step S14). However, at this point in time, none of the three users UA, UB, and UC has yet performed the approval process (the seal process), so that the seal information associated with the document ID does not yet exist, and the captured image The GC stamp fields (approval fields) SC1, SC2, SC3 remain blank (see also FIG. 8).

  Moreover, in said step S12, the portable terminal 70a transmits the identification number of an own apparatus to the server 50 also. The identification number (identification information of the mobile terminal possessed by the user UA) is used as stamper (authorizer) information.

  In step S13, the server 50 transmits the transmission source user (mobile phone) based on the identification number (of the mobile terminal 70a) transmitted from the mobile terminal 70a in step S12 and the data table TB2 (see FIG. 15 described later). The user of the terminal 70a is specified. Then, the server 50 also transmits an imprint image (specifically, image data) of the electronic seal stamp corresponding to the transmission source user to the portable terminal 70a.

  On the other hand, in step S14, as shown in FIG. 8, the portable terminal 70a displays the stamp button BN1 in the touch screen 71S. The stamp button BN1 is a button for a stamp operation described below. In addition, an imprint image MA of an electronic seal stamp related to the user UA is displayed above the stamp button BN1. This imprint image MA is an electronic seal stamp (imprint image) scheduled to be stamped in response to the pressing operation of the stamp button BN1. For example, in FIG. 8, a seal image MA1 in which the characters “Takeuchi” (user UA) are engraved is displayed at a position directly above the stamp button BN1.

  The electronic seal stamp to be stamped in response to the pressing operation of the stamp button BN1 is determined based on the data table TB2 or the like in the storage unit 55 of the server 50. In the data table TB2, a plurality of electronic seal stamp information (imprint image) MP1, MP2, MP3 is registered in advance for each user. An imprint image corresponding to the type of electronic document is (automatically) selected from the plurality of imprint images, and the selected imprint image is stored in association with the electronic document. Here, the imprint image MP1 is an imprint image used in “external document”, and the imprint image MP2 is an imprint image used in “internal document”. The imprint image MP3 is an imprint image used for “other documents”. FIG. 15 shows a state in which the imprint images MP1 (MA1), MP2 (MA2), and MP3 (MA3) relating to the user UA are registered in the data table TB2. Further, in FIG. 15, imprint images MP1 (MB1) and MP2 (MB2) are registered for the user UB, and imprint images MP1 (MC1) and MP2 (MC2) are registered for the user UC.

  Further, the server 50 refers to the document type information (“external document”, “internal document”, “other”) stored in association with the document ID “001” in the data table TB1, and the document type An imprint image corresponding to the information is selected from a plurality of imprint images MP1, MP2, and MP3. For example, based on the fact that the document type information of the document ID “001” is “external document”, the imprint image MP1 (MA1) related to the user UA is determined as the use image (imprint image to be used).

  In this manner, the seal image MA (MA1) of the electronic seal stamp relating to the user UA is temporarily displayed as a confirmation image in the touch screen 71S of the mobile terminal 70a (specifically, the position directly above the button BN1).

  Here, it is assumed that the user UA (section manager) has confirmed the contents in advance using the paper document DP and has already decided to approve the electronic document DE (in other words, the paper document DP). And according to this decision, user UA (section manager) performs electronic stamping operation (approval operation) using portable terminal 70a. Specifically, a stamp button BN1 (see FIG. 8) provided in the touch screen 71S of the mobile terminal 70a is pressed by the user UA.

  In step S15, the portable terminal 70a transmits a stamp instruction DR (DR1) to the server 50 in response to the pressing operation of the stamp button BN1. The stamp instruction DR1 includes a document ID (“001”) of a stamp target (approval target) and stamper (authorizer) information (here, identification information of a mobile terminal possessed by the user UA).

  In step S16, the server 50 updates the data table TB1 (FIG. 14) in accordance with the stamp instruction DR1. Specifically, the server 50 adds the seal information MA of the user UA to the electronic document DE (DE1) with the document ID “001”. More specifically, an imprint image MA1 of an electronic seal stamp related to the user UA is added as information corresponding to the stamp field SC1 of the electronic document DE1. As described above, the electronic seal stamp information of the authorized user corresponding to the mobile terminal 70a is stored in the data table TB1 in association with the electronic document DE1 as the stamp information for the electronic document DE1.

  In addition, when the update completion of the data table TB1 is notified from the server 50 to the mobile terminal 70a, the mobile terminal 70a applies an imprint to the stamp field SC1 of the captured image GC displayed on the display unit 6b of the mobile terminal 70a. The image MA1 is superimposed and displayed (step S17).

  In this way, an approval process (stamping process) by the user UA (section manager) is executed for the electronic document DE.

  Next, the approval process regarding the user UB (director) who is the second approver will be described with reference to FIGS. 6, 9, 10, and the like.

  The user UB photographs the paper document DPb including the identification image GD using the mobile terminal 70b (step S11). Specifically, in response to the shooting operation of the user UB, the mobile terminal 70b captures the paper document DP using the imaging unit 73, and acquires a captured image GC (GCb) related to the paper document DP.

  The portable terminal 70b extracts the document ID included in the identification image GD in the captured image GCb from the identification image GD, and transmits the extracted document ID to the server 50 (step S12). At this time, the portable terminal 70b also transmits the identification number of the own device to the server 50.

  The server 50 refers to the data table TB1 (FIG. 14), specifies the target document based on the document ID transmitted from the portable terminal 70b, and also specifies the stamp information associated with the document ID. The paper document DPb and the paper document DPa are printouts related to the same electronic document DE, and the document ID of the paper document DPb and the document ID of the paper document DPa are the same. Therefore, here, the seal information (specifically, the seal image MA1 (the seal image in which the characters “Takeuchi” are engraved)) is specified as the seal information associated with the document ID. Then, the server 50 transmits the specified seal information to the mobile terminal 70b (step S13).

  On the other hand, the mobile terminal 70b displays the captured image GC of the paper output document DPb corresponding to the electronic document DE on the display unit 72 (touch screen 71S), and displays the stamp information transmitted from the server 50 in the captured image. The image is displayed superimposed on the GC (step S14). At this time, only the user UA performs the approval process (the seal process), and the seal information associated with the document ID (specifically, the seal image MA1 (the seal image in which the characters “Takeuchi” are engraved)). The image is displayed in a superimposed manner on the stamp field (approval field) SC1 of the captured image GC (see also FIG. 10).

  Moreover, in said step S12, the portable terminal 70b transmits the identification number of an own apparatus to the server 50 also. The identification number (identification information of the mobile terminal possessed by the user UB) is used as stamper (authorizer) information.

  In step S13, the server 50 selects the transmission source user (user of the portable terminal 70b) based on the identification number (of the portable terminal 70b) transmitted from the portable terminal 70b in step S12 and the data table TB2. Identify. Then, the server 50 also transmits the seal image (specifically, the image data) of the electronic seal stamp corresponding to the transmission source user to the portable terminal 70b.

  On the other hand, in step S14, as shown in FIG. 8, the portable terminal 70b displays the stamp button BN1 in the touch screen 71S. The stamp button BN1 is a button for a stamp operation described below. In addition, an imprint image MB of an electronic seal stamp related to the user UB is displayed above the stamp button BN1. This imprint image MB is an electronic seal stamp (imprint image) scheduled to be stamped in response to the pressing operation of the stamp button BN1. For example, in FIG. 10, an imprint image MB1 in which the characters “Okamoto” are engraved is displayed at a position immediately above the stamp button BN1. The imprint image MB1 is determined based on the data table TB2 and the like. For example, based on the fact that the document type information of the document ID “001” is “external document”, the seal image MP1 (MB1) related to the user UB is determined as the use image.

  Here, it is assumed that the user UB has confirmed the content in advance using the paper document DPb and has already decided to approve the electronic document DE (in other words, the paper document DP). Then, according to this decision, the user UB performs an electronic stamping operation (approval operation) using the mobile terminal 70b. Specifically, a stamp button BN1 (see FIG. 10) provided in the touch screen 71S of the mobile terminal 70b is pressed by the user UB.

  In step S15, the portable terminal 70b transmits a stamp instruction DR (DR2) to the server 50 in response to the pressing operation of the stamp button BN1. The stamp instruction DR2 includes a document ID (“001”) to be stamped and stamper (authorizer) information (here, identification information of the portable terminal possessed by the user UB).

  In step S16, the server 50 updates the data table TB1 based on the stamp instruction DR2. Specifically, the stamp information (MB) of the user UB is added to the electronic document DE with the document ID “001”.

  Further, when the update completion of the data table TB1 is notified from the server 50 to the portable terminal 70b, the portable terminal 70b displays the imprint image MB1 in the stamp column SC2 of the photographed image GC displayed on the display unit 6b. Superimposed and displayed (step S17).

  In this way, the approval process (stamping process) by the user UB (department manager) is executed for the electronic document DE.

  Next, the approval process regarding the user UB (director) who is the third approver is executed in the same manner (see FIGS. 6, 11, and 12).

  Specifically, the user UC (for example, the president) captures the paper document DPc including the identification image GD with the mobile terminal 70c after the users UA and UB have electronically stamped, and the mobile terminal 70c A captured image GCc according to the above is acquired. The portable terminal 70 c extracts the document ID included in the identification image GD in the captured image GCc, and transmits the extracted document ID to the server 50. The server 50 identifies a document based on the document ID, and displays the identified electronic document DE on the mobile terminal 70c. At this time, based on the stamp information by the users UA and UB, two imprint images MA1 and MB1 relating to the stamped users UA and UB are superimposed and displayed on the electronic document DE. Thereafter, when the user UC further performs a seal process using the seal image MC1 using the mobile terminal 70c, the seal process on the electronic document DE is completed.

  Thereby, in the data table TB1 in the server 50, it is stored that three stamping processes have been performed on the electronic document DE.

  Further, when the print output instruction for the electronic document DE is given after the approval process for the electronic document by each of the users UA, UB, and UC as described above, the MFP 10 generates (outputs) a print output as shown in FIG. To do. This printed output is printed out with the stamp information superimposed on the electronic document DE. More specifically, seal images MA1, MB1, and MC1 relating to the electronic seal stamp are printed out and superimposed on the stamp fields SC1, SC2, and SC3, respectively. Such a print output instruction may be given from the portable terminal 70 to the MFP 10 via the server 50, for example. In this case, the electronic document DE may be specified as the document to be printed based on the captured image GC of the paper document DP by the portable terminal 70. Alternatively, an electronic document to be printed may be specified by a direct operation on the MFP 10 and a print output instruction may be directly given from the user to the MFP 10.

  According to the operation as described above, a paper document printed out by the MFP 10 (specifically, the print output unit 3) is photographed using the imaging unit 73 of the portable terminal 70, and from the identification image GD in the photographed image GC. Based on the extracted document ID, the electronic document DE corresponding to the paper document DP is specified by the server 50. Then, in the server 50, in response to the seal instruction from the mobile terminal 70, the electronic seal stamp information (imprint image, etc.) of the user corresponding to the mobile terminal 70 is associated with the electronic document DE as the seal information for the electronic document. Remembered. Therefore, based on the document ID extracted from the identification image GD in the captured image GC obtained by photographing the paper document DP, the electronic document DE corresponding to the paper document DP is specified by the server 50, and the electronic document DE is electronically stored. It is possible to perform a stamping process. Further, the approval user can check the content of the document while ensuring high visibility by browsing the document using the paper document DP. Specifically, the authorized user can confirm one page and / or a plurality of pages in whole or in detail by using the paper document DP without being restricted by the size of the display unit of the mobile terminal. it can. In this way, it is possible to improve the convenience of the user when performing the electronic stamping process.

  Further, the server 50 acquires the stamp information for the electronic document DE specified based on the document ID based on the data table TB1, and directs the acquired stamp information to the portable terminal 70 for superimposed display on the captured image. Send as information. According to this, the portable terminal 70 can display the stamp information superimposed on the captured image GC. Therefore, each user can easily confirm the presence or absence of the stamping process (approval process) by the approver.

  Furthermore, the electronic seal stamp information of the user corresponding to the mobile terminal 70 is the type of electronic document DE (“internal document”, “external document”, etc.) from among a plurality of electronic seal information registered in advance for each user. Depending on (automatically). Therefore, each approver (authorization user) can easily use his or her own electronic seal stamps.

  In the above embodiment, the content of the electronic document is not displayed on the mobile terminal 70 using the data of the electronic document DE, but the captured image GC of the paper document DP corresponding to the electronic document is displayed on the mobile terminal 70. Is displayed. According to this, since it is not necessary to download the data of the electronic data DE itself from the server 50 to the portable terminal 70, the amount of data communication can be suppressed.

<2. Second Embodiment>
The second embodiment is a modification of the first embodiment. Below, it demonstrates centering on difference with 1st Embodiment.

  In the second embodiment, an example is shown in which changes to the paper document after the print output time can be presented to the user.

  In the second embodiment, the electronic document DE is updated by a device other than the mobile terminal 70. For example, update processing (such as changing document contents) for the electronic document DE is performed by another computer (not shown) or the like that can be connected to the server 50 via a network, and the updated electronic document is overwritten and stored in the server 50. Note that the present invention is not limited to this, and the update process for the document may be performed using the mobile terminal 70 (described later).

  The server 50 according to the second embodiment also has a data table TB3 (see FIG. 16). In the data table TB3, update information regarding the update time and update contents (difference information) of the electronic document DE is recorded. The data table TB3 is updated every time the electronic document DE is updated. As described above, the server 50 also manages update information (including the update time and update contents of each electronic document) regarding each electronic document.

  FIG. 16 shows an example of recorded contents in the data table TB3. In FIG. 16, after the data was first created (updated) at time T10 (“July 10, 2011 13:05:00”), the data was also updated at times T20, T30, and T40. It is shown. However, in the following, the description will be started assuming that only data at time T10 is recorded among data relating to times T10, T20, T30, and time T40.

  At the print output time T11 of the paper document DP after the time T10, the identification image GD printed on the paper document DP is formed in a state that also includes information on the update time of the electronic document DE corresponding to the paper document DP. The Specifically, in the identification image GD, the latest document update time at the time of print output of the paper document DP is encoded and included. For example, the latest document update time T10 (“July 10, 2011 13:05:00”) at the print output time T11 (“July 10, 2011 15:10:00”) is encoded. And embedded as a part of the identification image GD (two-dimensional barcode).

  Thereafter, when the electronic document DE is updated at time T20 (“July 11, 2011, 10:45:00”), the update time and the update content regarding the electronic document DE are stored in the data table TB3. For example, when there is a change in the content of the text (when the character “8000 yen” in the text is changed to “5000 yen”), the update time T20 is stored and the difference between before and after the update is stored. Difference information is stored as update content (text change content).

  Further, after time T25, display processing of the electronic document DE and the like are executed on the display unit 72 of the portable terminal 70 in the same manner as in FIG.

  FIG. 17 is a diagram illustrating an operation according to the second embodiment. FIG. 17 illustrates an electronic document display process or the like accompanying a shooting operation by the user UB.

  As shown in FIG. 17, also in the second embodiment, the same processes (steps S21 to S27) as the processes of steps S11 to S17 of FIG. 6 are executed. However, as described below, the update contents from the time T10, which is the document update time embedded in the identification image GD printed out on the paper document DP, to the current time (time T25) (the document update immediately before the current time). Time T20 (including the updated contents at the current document update time of the electronic document) is also exchanged between the portable terminal 70b and the server 50.

  Specifically, in step S22 after the photographing process (step S21), the document ID is extracted from the identification image GD of the paper document DP. Furthermore, it is assumed here that the document update time T10 and the page number are also extracted from the identification image GD. Then, the extracted information (document ID, page number, document update time) and identification information (terminal identification information) of the portable terminal 70 b are transmitted to the server 50.

  In step S23, the server 50 refers to the data table TB1, specifies the electronic document corresponding to the document ID, and acquires the stamp information (approval information) related to the electronic document. When the stamp information exists, the server 50 transmits the stamp information (for example, the stamped imprint image MA1 (“Takeuchi”)) to the mobile terminal 70.

  Further, the server 50 specifies the electronic seal stamp of the user UB corresponding to the terminal identification information of the mobile terminal 70b based on the mobile terminal identification information and the data table TB2, and information on the electronic seal stamp (imprinted image for stamping). Is also transmitted to the portable terminal 70.

  Furthermore, the server 50 refers to the data table TB3 (FIG. 16) and also acquires the latest update time (for example, time T20) of the electronic document at the current time. When the latest update time T20 is a time later than the above time T10 (in other words, when the update process is performed at a time T20 after the time T10), the time T10 starts from the time T10. The update contents (specifically, difference information) updated up to the present time are also transmitted from the server 50 to the portable terminal 70b as superimposed display information. Specifically, the updated content (difference information) at time T20 is transmitted as the superimposed display information.

  In step S24, when the display target page is a stamp page (for example, the first page), the mobile terminal 70b uses the stamp information to add the stamped imprint image MA1 (“Takeuchi”) to the captured image GC. Superimposed display. In the example illustrated in FIGS. 17 and 18, the display target page is a page other than the stamp page (for example, the second page), and the stamped imprint image MA1 (“Takeuchi”) is not displayed. In addition, the mobile terminal 70b displays an image of the electronic seal stamp of the user UB (for example, a seal image including the characters “Okamoto”) and the button BN1 on the screen. Further, when there is an update content, the mobile terminal 70b also displays the update content (difference information) superimposed on the captured image GC.

  In FIG. 18, in addition to the captured image GC and the button BN1 of the second page of the paper document DP, the updated content (difference information) at time T20 is also displayed on the display screen of the mobile terminal 70b. Here, it is shown that the character “8000 yen” is changed to “5000 yen” at the positions of the fifth to ninth characters on the third line of the second page.

  Thereafter, in step S25 and subsequent steps, the same stamping process and the like as in step S15 and subsequent steps are executed.

  In the above description, the electronic document display process accompanied by the photographing operation by the user UB has been mainly described, but the same process is executed for the other users UA and UC.

  According to the above aspect, when the latest update time T20 at the current time is a time later than the latest time T10 at the print output time T11, the server 50 updates between the time T10 and the current time. The updated content (specifically, the updated content at time T20) is also transmitted to the portable terminal 70 as the superimposed display information. Therefore, the updated content can be easily displayed on the mobile terminal 70. Therefore, a user (an approved user or the like) can confirm using the paper document DP, and can confirm a partial change content (update content) with the content displayed on the mobile terminal 70. Further, thereafter, the approval user can perform an electronic stamping process.

  In addition, in the above, the mode in which difference information (update content) is displayed when there is a change in the content of the text (when the character “8000 yen” in the text is changed to “5000 yen”) is illustrated. However, it is not limited to this. For example, “additional comment” (see also the third embodiment) may be displayed as the updated content (difference information).

  In addition, when a paper document is printed at time T11 and the processes in steps S21 to S27 are executed at time T45 after time T40, in steps S23 and S24, between time T10 and time T45. Changes (difference information) during the period are exchanged and displayed. Specifically, the change content at time T20, the change content at time T30, and the change content at time T40 are transmitted from the server 50 to the mobile terminal 70 and displayed on the mobile terminal 70. In addition, the change regarding drawing should just show the new drawing after a change as update content on the display part 72 of the portable terminal 70 with characters, such as "drawing has been changed."

  Further, the paper document DP is printed at time T21 between time T20 and time T30, and the processing of steps S21 to S27 is executed at time T35 (time between time T30 and time T40) thereafter. May be. In this case, in steps S <b> 23 and S <b> 24, the changed content at time T <b> 30 is exchanged between the server 50 and the portable terminal 70 and displayed on the portable terminal 70.

<3. Third Embodiment>
The third embodiment is a modification of the first embodiment. Below, it demonstrates centering on difference with 1st Embodiment.

  In the third embodiment, an example in which an update operation or the like for an electronic document is executed using the mobile terminal 70 is illustrated.

  Further, here, a case where an allowable update operation or the like is different for each user (for each portable terminal 70) is illustrated. More specifically, the server 50 specifies a processing menu allowed for the user of the mobile terminal based on the terminal identification information transmitted from the mobile terminal 70, and also displays information related to the processing menu for the superimposed display. Send as information. Then, the server 50 executes the specific action for the electronic document DE in response to an execution instruction (specifically, a document change instruction and comment addition) other than the stamp instruction that is an execution instruction for the specific action included in the processing menu. Execute the process.

  FIG. 19 is a diagram illustrating an operation according to the third embodiment. FIG. 19 illustrates an electronic document display process or the like accompanied by a photographing operation by the user UB.

  As shown in FIG. 19, also in the third embodiment, the same processes (steps S31 to S37) as the processes of steps S11 to S17 of FIG. 6 are executed. However, as will be described below, in the third embodiment, it is possible to execute not only a seal instruction but also various other actions on the electronic document.

  In step S32 after the photographing process (step S31) in FIG. 19, the document ID and the page number are extracted from the identification image GD of the paper document DP. Then, the extracted information (document ID, page number) and identification information (terminal identification information) of the portable terminal 70 b are transmitted to the server 50.

  In step S33, the server 50 refers to the data table TB1 (FIG. 14), specifies the electronic document corresponding to the document ID, and acquires the stamp information related to the electronic document. When the stamp information exists, the server 50 transmits the stamp information (for example, the stamped imprint image MA1 (“Takeuchi”)) to the mobile terminal 70.

  Further, the server 50 specifies the electronic seal stamp of the user corresponding to the mobile terminal identification information based on the mobile terminal identification information and the data table TB22 (FIG. 22), and transmits the electronic seal stamp information to the mobile terminal 70. In the third embodiment, a data table TB22 is provided as the data table TB2.

  Furthermore, the server 50 specifies a process (permission process) permitted to the user UB corresponding to the mobile terminal identification information based on the mobile terminal identification information and the data table TB22, and includes a process menu MN ( Specifically, the processing item or the like is transmitted to the portable terminal 70. As shown in FIG. 22, permission processing information for each user is stored in the data table TB22. For example, three processes (process items) of “add comment”, “document change”, and “seal process” are stored as permission processes for the user UB. The server 50 identifies these three processes as permission processes based on the data table TB22.

  In step S34, when the display target page is a stamped page (for example, the first page), the portable terminal 70b uses the stamped information on the imprinted image MA1 (“Takeuchi”) as the captured image GC. Superimposed display. In the example shown in FIGS. 19 to 21, the display target page is a page other than the stamp page (for example, the second page), and the stamped imprint image MA <b> 1 (“Takeuchi”) is not displayed.

  In addition, the mobile terminal 70b displays the processing menu MN on the screen.

  Specifically, as shown in FIG. 20, in addition to the captured image GC of the second page of the paper document DP, the processing menu MN is also displayed on the display screen of the portable terminal 70b. Here, a process menu MN including three processes (“comment addition”, “document change”, and “seal process”) permitted to the user UB is displayed.

  Thereafter, in step S35, an action execution instruction is given using the process menu MN, an information updating operation based on the action execution instruction is performed in step S36, and a display content updating operation in the portable terminal 70 is performed in step S37. .

  For example, in step S35, when the user UB adds a check mark to the check box for adding a comment in the process menu MN (see FIG. 21), an add button BN5 is displayed on the mobile terminal 70b and a comment by the user UB is displayed. An add operation (described below) is accepted. Specifically, the user UB taps a desired position in the captured image GC, and an arbitrary character string (for example, “numerical value correction is necessary”) is displayed in a balloon image displayed with the tap position as a reference point. input. Then, the add button BN5 is pressed. In this way, an action execution instruction (specifically, a comment addition instruction) is given. In response to the execution instruction, the mobile terminal 70 creates data in which the input character string is associated with the position in the document corresponding to the tap position in the captured image GC, and transmits the data to the server 50. To do.

  The server 50 executes an information update operation based on the action execution instruction (comment addition instruction) (step S36). More specifically, operations such as storing the contents of change (contents of additional comments, comment addition positions, etc.) in the data table TB3 (FIG. 16) etc. are executed. Moreover, the portable terminal 70 displays the content reflecting the change content based on action execution instruction on the display part 72 (touch screen 71S). Specifically, an additional comment (for example, a character string “necessary for numerical correction”) is superimposed on the captured image GC, and the add button BN5 is deleted (step S37). And it returns to the state of FIG. 20 again and the operation | movement of step S35-S37 is performed repeatedly.

  Similar processing is also executed for the other actions “document change” and “seal processing”.

  According to such an aspect, the server 50 specifies a processing menu allowed for the user of the mobile terminal based on the terminal identification information transmitted from the mobile terminal 70, and also includes information related to the processing menu. Transmit as superimposition display information. Therefore, the processing menu allowed for the user of the mobile terminal is appropriately displayed on the mobile terminal 70. In addition, the permission process can be set for each user.

  Further, the server 50 executes the specific action for the electronic document DE in response to an execution instruction (specifically, a document change instruction and comment addition) other than the stamp instruction that is an execution instruction for the specific action included in the processing menu. The process which concerns on is performed. Therefore, the user can easily give a specific action execution instruction using the mobile terminal 70.

<4. Fourth Embodiment>
The fourth embodiment is a modification of the first embodiment. Below, it demonstrates centering on difference with 1st Embodiment.

  In the fourth embodiment, an example in which a voice message input using the portable terminal 70 is stored in the server 50 in association with an electronic document is illustrated.

  23 and 24 are diagrams illustrating operations according to the fourth embodiment. FIG. 23 shows an electronic document display process or the like accompanied by a photographing operation by the user UA, and FIG. 24 shows an electronic document display process or the like accompanied by a photographing operation by the user UB.

  As shown in FIGS. 23 and 24, also in the fourth embodiment, the same processes (steps S41 to S47) as the processes of steps S11 to S17 of FIG. 6 are executed. However, in the third embodiment, not only the electronic seal is realized, but also a voice message can be stored along with the electronic seal.

  In step S42 after the photographing process (step S41) in FIG. 23, the document ID and the page number are extracted from the identification image GD of the paper document DP. Then, the extracted information (document ID, page number) and identification information (terminal identification information) of the portable terminal 70a are transmitted to the server 50.

  In step S43, the server 50 refers to the data table TB1 (FIG. 14), specifies the electronic document corresponding to the document ID, and acquires the stamp information related to the electronic document. When the stamp information exists, the server 50 transmits the stamp information to the portable terminal 70a.

  Further, the server 50 specifies the user's electronic seal stamp corresponding to the mobile terminal identification information based on the mobile terminal identification information and the data table TB2 (FIG. 15), and transmits the electronic seal stamp information to the mobile terminal 70a.

  In step S44, the portable terminal 70a, if there is a stamped electronic seal stamp for the electronic document DE and the display target page is a stamp page (for example, the first page), based on the stamp information, The completed seal image is superimposed on the captured image GC and displayed. It should be noted that the imprint image is not displayed when the stamp information does not yet exist. In addition, the mobile terminal 70a displays an image of the electronic seal stamp of the user UA (for example, a seal image MA1 including the characters “Takeuchi”) and a button BN1 (see also FIG. 8).

  Thereafter, in step S45, the user UA performs an electronic stamping operation (approval operation) using the mobile terminal 70a. A stamp button BN1 (see FIG. 8) provided in the touch screen 71S of the portable terminal 70a is pressed by the user UA. When the button BN1 is pressed, the portable terminal 70a transmits a stamp instruction DR (DR1) to the server 50 in response to the pressing operation.

  Further, a confirmation screen GA4 as shown in FIG. 25 is continuously displayed on the touch screen 71S of the portable terminal 70a. The confirmation screen GA4 includes a display image that displays a character string “Do you want to record a voice message?” And buttons BN6 and BN7. When the user UA presses the “YES” button BN6, a voice recording start instruction can be given to the portable terminal 70a. In response to the voice recording start instruction, the portable terminal 70a displays the screen GA5 (FIG. 26) on the touch screen 71S of the portable terminal 70a and records voice using the microphone (not shown) of the portable terminal 70a. Start. A message “Recording” is displayed on the screen GA5. Further, an end button BN8 is provided on the screen GA5. When the user UA finishes speaking a voice message (for example, “please confirm xx by July 15”), the user UA presses the end button BN8.

  The mobile terminal 70a transmits a voice message to the server 50 in response to the stamping operation (pressing operation of the end button BN8).

  In step S46, the server 50 updates the data table TB1 based on the received voice message and the stamp instruction DR1. Specifically, the stamp information (MA) and voice message (voice data) of the user UA are added to the electronic document DE with the document ID “001”. That is, the server 50 stores the audio data transmitted from the portable terminal 70 in response to the seal instruction DR1 from the portable terminal 70 in the data table TB1 (management information) in association with the electronic document DE (DE1).

  Further, when the update completion of the data table TB1 is notified from the server 50 to the mobile terminal 70a, the mobile terminal 70a applies an imprint to the stamp field SC1 of the captured image GC displayed on the display unit 6b of the mobile terminal 70a. The image MA1 is superimposed and displayed (step S47).

  In this way, an approval process (stamping process) by the user UA (section manager) is executed for the electronic document DE.

  Next, an approval process related to the user UB (director) who is the second approver will be described with reference to FIG.

  In step S42 after the photographing process (step S41) in FIG. 24, the document ID and the page number are extracted from the identification image GD of the paper document DP. Then, the extracted information (document ID, page number) and identification information (terminal identification information) of the portable terminal 70 b are transmitted to the server 50.

  In step S43, the server 50 refers to the data table TB1, specifies the electronic document corresponding to the document ID, and acquires the stamp information related to the electronic document. When the stamp information exists, the server 50 transmits the stamp information to the portable terminal 70b.

  Further, the server 50 specifies the user's electronic seal stamp corresponding to the mobile terminal identification information based on the mobile terminal identification information and the data table TB2, and transmits the electronic seal stamp information to the mobile terminal 70b.

  Furthermore, the server 50 also transmits data VT (described later) obtained by converting the voice message into text (character string) as superimposed display information to the portable terminal 70b. The data VT is data converted from a voice message (voice data) to text data by a voice recognition technique. The data VT is generated by the server 50 or the like.

  In step S44, according to the subroutine processing (step S70) shown in FIG. 27, the portable terminal 70b executes a display operation related to the seal information and the like.

  Specifically, if it is determined in step S71 that there is no voice message associated with the electronic document DE (DE1), the process proceeds to step S74.

  In step S74, the portable terminal 70b superimposes the imprinted image (for example, the imprinted image MA1 including the characters “Takeuchi”) on the photographed image GC (specifically, the imprint column SC1) based on the imprint information. To display. In addition, the mobile terminal 70b displays an image of the electronic seal stamp of the user UB (for example, a seal image MB1 including the characters “Okamoto”) and a button BN1 on the screen (see FIG. 10).

  On the other hand, if it is determined in step S71 that there is a voice message associated with the electronic document DE (DE1), the process proceeds to step S72.

  In step S72, it is determined whether or not voice reproduction by the portable terminal 70b is possible (whether or not the portable terminal 70b has a voice data reproduction function). When audio reproduction by the portable terminal 70b is not possible, the process proceeds to step S75. Further, when sound reproduction by the portable terminal 70b is possible, the process proceeds to step S76.

  In step S75, a screen GA7 as shown in FIG. 28 is displayed. On the screen GA7, as in FIG. 10, a stamped imprint image (an imprint image MA1 including the characters “Takeuchi”) is displayed superimposed on the captured image GC, and an image of the user UB's electronic seal stamp (“ An imprint image MB1) including the characters “Okamoto” and a button BN1 are displayed. Further, on the screen GA7, the data VT obtained by converting the voice message from the user UA into text is also displayed superimposed on the captured image GC. More specifically, the data VT is displayed together with a balloon image starting from the stamp field SC1 of the user UA.

  In step S76, a screen GA8 as shown in FIG. 29 is displayed. On the screen GA8, in addition to the display contents similar to those in FIG. 10, a menu MV relating to the reproduction of the voice message is further displayed. In the menu MV, “There is a voice message. Do you want to play it?” Is displayed, and “YES button” (voice start button) and “NO button” (cancel button) are also displayed. Yes.

  When the user UB presses the “YES button”, a voice message transfer command is transmitted from the portable terminal 70 b to the server 50. Thereafter, in response to the transfer command, a voice message (voice data) is transferred from the server 50 to the portable terminal 70b, and the received voice message is reproduced on the portable terminal 70b.

  Thereafter, the same operation as described above is executed after step S45. As a result, a stamping process or the like based on a stamping operation (approval operation) by the user UB is performed, and a voice message (voice data) is recorded, transferred, or stored.

  In this way, display processing and approval processing (stamping processing) of the captured image GC by the user UB is performed on the electronic document DE.

  According to such an aspect, the server 50 stores the voice message input using the portable terminal 70 in association with the electronic document DE. Therefore, the voice message can be electronically managed in association with the electronic document DE.

  In addition, depending on the presence or absence of the playback function of the portable terminal 70, the voice playback operation related to the voice data and the display operation of the data VT obtained by converting the voice data into text data are automatically switched. Therefore, the voice data can be used easily and effectively.

  Note that, in the above, the case where the server 50 generates the data VT obtained by converting the voice data into text is not limited to this. For example, the data VT is generated by the mobile terminal 70b. Also good.

<5. Fifth Embodiment>
The fifth embodiment is a modification of the first embodiment. Below, it demonstrates centering on difference with 1st Embodiment.

  In the fifth embodiment, a mode in which an “approval request” is also transmitted to the next approver of a certain approver based on the position information of each approver and the like will be described. Note that the approval order for the electronic document DE is determined in advance, and is stored in, for example, the data table TB1 (TB15) (FIG. 30). In FIG. 30, it is recorded that the users UA, UB, and UC are approvers for the electronic document DE, and approval is performed in this order. It is also recorded that the user UE is a proxy approver of the user UA and the user UF is a proxy approver of the user UB.

  Each of the mobile terminals 70a, 70b, and 70c in the fifth embodiment has a GPS (Global Positioning System) function. The position information of each user is acquired by the GPS function of each portable terminal 70a, 70b, 70c. The acquired position information is stored in association with each user (mobile terminal) in the data table TB2 (FIG. 15), for example. In this embodiment, immediately after the approval of a certain approver is completed, the position information of the certain approver and the position information of the next approver are transmitted from each portable terminal 70 to the server 50, The server 50 grasps the position information of each mobile terminal. However, the present invention is not limited to this, and the position information of each user may be constantly grasped by the server 50 by a regular communication operation between each portable terminal 70 and the server 50.

  In this embodiment, the “approval request” is different from each other based on the relationship between the locations of both users (specifically, the distance between both users and the type (attribute) of the location of the next user). It is executed for the next approver or the like in a manner. For example, an approval request is notified to the next approver by a method based on the data table TB5 (FIG. 31). The data table TB5 is data stored in the server 50 or the like.

  In the data table TB5 of FIG. 31, an approval request operation according to the distance between both users and the attribute information of the next user's location is defined.

As shown in the uppermost row of the data table TB5, when the condition CN1 is satisfied, the approval request action AN1 is adopted. Condition CN1 is that the distance between two users (the distance between the position of an approver (authorized user) and the position of the next approver) is smaller than a predetermined distance TH5 (for example, several hundred meters) (distance “Small”), and the location of the next approver (authorization user) and the location of the previous approver are both the same site in the company. In addition, approval request action AN1 is a "prompting to the documents passed by hand carry" effect of the operation.

  Further, as shown in the second row from the top of the data table TB5, when the condition CN2 is satisfied, the approval request action AN2 is adopted. The condition CN2 is that the distance between the two users is greater than the predetermined distance TH5 (distance “large”), and the position of the next approver (approved user) and the position of the previous approver are “any” "In-house but different sites". Further, the approval request action AN2 “prints out the electronic document with the nearest print output device (such as MFP) of (the next approver), and transmits an approval request mail (to the next approver)” This is the effect.

  Further, as shown in the third row from the top of the data table TB5, when the condition CN3 is satisfied, the approval request action AN3 is adopted. Condition CN3 is that the distance between the two users is greater than the predetermined distance TH5 (distance “large”), and the location of the next approver (authorized user) is “moving outside the company” It is. Further, the approval request action AN3 is an operation to “send an approval request mail (to the next approver)”.

  Further, as shown in the lowermost row of the data table TB5, when the condition CN4 is satisfied, the approval request action AN4 is adopted. Condition CN4 is that the distance between the two users is greater than the predetermined distance TH5 (distance “large”), and the location of the next approver (authorized user) is “home (outside)”. is there. Further, the approval request action AN4 is an operation of “transmit proxy approval request mail toward proxy approver”.

  FIG. 32 is a diagram illustrating an operation according to the fifth embodiment. FIG. 32 shows an electronic document display process and a seal process associated with a shooting operation by the user UA.

  As shown in FIG. 32, also in the fifth embodiment, the same processes (steps S51 to S57) as the processes of steps S11 to S17 of FIG. 6 are executed. However, in this fifth embodiment, as described below, after the approval process by the user UA (steps S55 to S57), the approval request process for the user UB (steps S61 to S65) is executed.

  Specifically, in response to the completion of the stamping process or the like (steps S55 to S57), in step S61, the server 50 sets each of the mobile terminal 70a of the user UA and the mobile terminal 70b of the user UB who is the next approver. In response to the request, transmission of the location information of each portable terminal is requested.

  In response to the transmission request, the mobile terminals 70a and 70b transmit the position information of the mobile terminals to the server 50 in step S62. For example, the portable terminal 70a transmits position information indicating the position of the company CA in the Osaka site to the server 50, and the portable terminal 70b transmits position information indicating the position of the same company CA in the Tokyo site to the server 50. .

  The server 50 determines the proposal content related to the approval request method based on the received position information and the data table TB5.

  Specifically, which of the above conditions CN1 to CN4 is determined is determined based on the position information of the mobile terminals 70a and 70b, and an approval request action corresponding to the corresponding condition CNi is determined by the user UA (current approval) (Provision operator (approval operator)).

  For example, if it is determined that the condition CN2 is satisfied, the approval request action AN2 corresponding to the condition CN2 is determined as the proposal content.

  And the server 50 transmits the display data regarding the said proposal content with respect to the portable terminal 70a (step S63). The mobile terminal 70a updates the display content of the display unit 72 (touch screen 71S) of the mobile terminal 70a using the received display data (see FIG. 33).

  FIG. 33 is a diagram showing a display screen GA9 for proposing an approval request action AN2. On the screen GA9, the proposal content related to the approval request method is displayed. Specifically, the text “The next approver is at another site. Do you want to print out with the nearest print output device and send an approval request email?” And the “YES button” is displayed. (Proposal acceptance button) and “NO button” (cancel button) are also displayed.

  When the “YES button” is pressed and the proposal content is accepted, the portable terminal 70a instructs the server 50 to execute the proposed approval request action AN2. That is, an instruction to execute the approval request action is given to the server 50 from the portable terminal 70a.

  The server 50 specifies a print output device (for example, MPF) that is closest to the location of the next approver user UB, and prints out the electronic document DE using the specified print output device. Such an aspect is particularly useful when the user UB does not have the paper document DP at hand (or when it is unknown whether he / she has it). Further, it is preferable that the identification image GD is also given to the paper document DP output at this time.

  In addition, the server 50 transmits an approval request mail toward the mobile terminal 70b. Specifically, it transmits toward the registered mail address of the user UB. In the approval request email, for example, “A document has been created and the document has been printed out using the nearest print output device (device number XXX). Please confirm and approve.” Is included.

  On the other hand, the user UB confirms the approval request mail on the mobile terminal 70b. According to this, the user UA can easily transmit an approval request for the next approver (user UB) by electronic mail.

  Here, the aspect in which the approval request action AN2 is executed when the condition CN2 is satisfied has been mainly described. However, when other conditions are satisfied, the corresponding approval request action is executed. .

  For example, when the condition CN3 is satisfied, the approval request action AN3 is executed. Specifically, when the proposal content is accepted and execution of the approval request action AN3 is instructed (step S64), the server 50 transmits an approval request mail to the mobile terminal 70 corresponding to the next approver. The approval request e-mail includes, for example, a phrase such as “A document has been created. Please confirm and approve it”.

When the condition CN1 is satisfied, the approval request action AN1 is executed. Specifically, servers 50 transmits to the mobile terminal 70a of the original approver UA data for display on the approval request message. The approval request message includes, for example, a sentence such as “Because the next approver is at the same site, please hand a paper document (if necessary)”. The user UA confirms the message displayed on the display unit 72 of the mobile terminal 70a, and hands the paper document DP to the next user UB existing in the same site as necessary.

  If the condition CN4 is satisfied, the approval request action AN4 is executed. Specifically, when the proposal content is accepted and execution of the approval request action AN4 is instructed (step S64), the server 50 designates the approval request mail as the proxy approver of the next approver in the data table TB15 (FIG. 30). Etc., and is transmitted toward the mobile terminal 70 corresponding to the proxy approver. In the approval request email, for example, “We have created a document with document ID (XXXXXX), so please confirm it on behalf of Mr. Okamoto, the next approver. Is included.

  In this way, the approval process (stamping process) by the user UA (section manager) is executed for the electronic document DE, and the approval request process for the user UB as the next approver is also executed. Therefore, it is possible to more reliably proceed with the approval procedure by a plurality of persons.

  Similarly, after the approval process or the like by the user UB (steps S51 to S57), the same processes of steps S61 to S65 as described above are executed. Thereby, the approval request process for the user UC who is the next approver of the user UB is also executed.
