It includes a reception unit 17, an extraction unit 19, a display control unit 21 that displays content, an evaluation unit 41, and a change history association unit 61.

  User authentication unit 11 has previously registered user identification information for identifying a registered user who is permitted to use MFP 100 in advance, and identifies a user who logs in to MFP 100. For example, the MFP 100 registers a set of user identification information and a password as registration information regarding a registered user. When the user logs in to the MFP 100 using, for example, the PC 200 among the PCs 200, 200A to 200E and the mobile phones 220, 220A, 220B, the user authentication unit 11 transmits a login screen to the PC 200. When the user inputs the user identification information and the password to the PC 200, the user authentication unit 11 receives the combination of the user identification information and the password transmitted from the PC 200, and the received combination of the user identification information and the password. And registration information are compared. If the combination of the user identification information and the password received from the PC 200 matches the registration information, the user authentication unit 11 authenticates the user who uses the PC 200 and permits login. Hereinafter, a user authenticated by the user authentication unit 11 and permitted to log in is referred to as a login user.

  Further, when authenticating the user, the user authentication unit 11 sets the login user's user identification information as the login user among the PCs 200, 200A to 200E and the mobile phones 220, 220A, 220B until the login user logs out of the MFP 100. Is temporarily stored in the RAM 114 in association with the device identification information for identifying the device operated by the device. As the device identification information, for example, a network address assigned to the device in the LAN 103 and the Internet 105 can be used.

  When the user is authenticated by the user authentication unit 11, the CPU 111 receives data received from the device specified by the device identification information corresponding to the user identification information of the login user until the login user logs out of the MFP 100. Treat as input by the logged-in user.

  The content storage unit 13 receives content from the login user. For example, when content is received from a logged-in user who operates PC 200, a content designation screen is transmitted to PC 200. If the logged-in user designates content according to the content designation screen and instructs transmission, PC 200 designates the designated content as MFP 100. Send to. When the communication I / F unit 112 receives content from the PC 200, the content storage unit 13 acquires the received content, and stores the acquired content in the HDD 115 in association with the user identification information of the login user. When the login user specifies related content related to the content on the PC 200, the related content is stored in the HDD 115 in association with the content together with the content. Hereinafter, the login user who has received the content storage unit content is particularly referred to as a creation user.

  If the content is electronic data, the data format and its contents are not limited. Here, the content is data generated by a document editing program and is a presentation material that contains the plan of a new product. Will be described as an example.

  The content specified by the login user on PC 200 may be content stored on PC 200, content stored on HDD 115 of MFP 100, or a file server connected to LAN 103. If it is, the content stored in the file server may be used. In this case, the content storage unit 13 acquires content by downloading the content stored in the file server. The content acquired by the content storage unit 13 may be image data output by the document reading unit 130 reading the document.

  The browsing request reception unit 15 receives a browsing request from a login user. For example, when a browsing request is received from a logged-in user who operates the PC 200A, a content designation screen is transmitted to the PC 200A. The content designation screen includes selectable content identification information for identifying the content stored in the HDD 115 by the content storage unit 13. When a plurality of contents are stored in HDD 115, the content designation screen includes selectable content identification information for each of the plurality of contents. When the logged-in user indicates content identification information included in the content designation screen, PC 200 </ b> A transmits a browse request including the instructed content identification information to MFP 100. When the communication I / F unit 112 receives a browsing request from the PC 200A, the browsing request receiving unit 15 receives a browsing request by a login user who operates the PC 200A.

  Further, the browsing request receiving unit 15 determines whether or not the login user who has requested browsing is a creation user. The browsing request reception unit 15 identifies the content specified by the content identification information included in the browsing request from the content stored in the content storage unit 13 in the HDD 115, and is stored in association with the specified content. If the identification information is the same as the user identification information of the login user who has requested browsing, the login user who has requested browsing is determined to be the creation user. Hereinafter, a login user other than the creation user is referred to as an evaluation user. Upon receiving the browsing request, the browsing request receiving unit 15 outputs a display instruction to the display control unit 21. The display instruction includes the content identification information included in the browsing request, the distinction between the creation user and the evaluation user, and the device identification information of the device that has transmitted the browsing request.

  The display control unit 21 generates a screen for displaying content stored in the HDD 115 in response to a display instruction being input. The screen generated by the display control unit 21 is changed in the content stored in the HDD 115 by the change history association unit 61 described later, but is different before and after the content is changed. Hereinafter, the stage before the content is changed is called a pre-content correction stage, and the stage after the content is changed is called a post-content correction stage. Further, in the stage before content correction, a comment is associated with the content by the evaluation unit 41 described later, but this is different in the stage before and after the comment is associated with the content. Hereinafter, the stage before the comment is associated with the content is referred to as a pre-comment association stage, and the stage after the comment is associated with the content is referred to as a post-comment association post floor.

<Before content modification>
(Before attaching comments)
The display control unit 21 generates a screen for displaying the content stored in the content storage unit 13 when a display instruction is input from the browsing request reception unit 15 in the stage before associating a comment. It is sent to the device operated by the logged-in user who has requested browsing. Specifically, the display control unit 21 specifies the content specified by the content identification information included in the display instruction input from the browsing request reception unit 15 from the content stored in the HDD 115 by the content storage unit 13. Then, a screen for displaying the specified content is generated.

  The history presence information display unit 31 determines whether or not the related content has been changed based on the evaluation record input from the extraction unit 19. If the related content has been changed, the related content is changed together with the content. The history presence information indicating that it is present is displayed. Specifically, the history content information display unit 31 changes the related content depending on whether or not the related content change history is set in the item of the related content change history of the evaluation record input from the extraction unit 19. Judge that When the history presence information display unit 31 determines that the related content is changed, the history presence information display unit 31 acquires the position of the comment in the content set in the item of the position of the evaluation record, and acquires the content in the content included in the screen. The history presence information is displayed in association with the position of the comment. The history presence information is a button for instructing display of the related content change history set in the related content change history item of the evaluation record input from the extraction unit 19. When the button for instructing the display of the related content change history is instructed, the history presence information display unit 31 displays the related content change history in the item of the related content change history of the evaluation record.

  In the post-content correction stage, when the evaluation user B, the evaluation user C, and the evaluation user D browse the content A, the change history is displayed together with the changed content A, and the change history of the related content, reference content, and related content is displayed. If each exists, the related content, the reference content, and the change history of the related content are displayed. Thereby, the evaluation user B and the evaluation user C can know that the comment B or the item described in the comment C is reflected in the content A after the change. Further, although the evaluation user D has not input a comment, the evaluation user D can confirm the change corresponding to the comment input by the evaluation user B and the content changed by the creation user A.

  Hereinafter, the case where the evaluation record B and the evaluation record C illustrated in FIG. 11 are stored in the HDD 115 will be specifically described. In the evaluation record B shown in FIG. 11, the user A operates the PC 200 to log in to the MFP 100 as a creation user and inputs the content A, and the user B operates the PC 200A to log in to the MFP 100 as the evaluation user B and the content A It is generated when a comment B is input. The evaluation record B indicates that the evaluation user B designates the reference content B. Furthermore, in the evaluation record B, a change history B in which the creating user A changes the content A corresponding to the comment B is set. Furthermore, it is shown that the related content related to the content A is changed by the creation user A, and the evaluation user D is designated as the second additional evaluation user.

  The evaluation record C is generated when the user C operates the PC 200B to log in to the MFP 100 as the evaluation user C and inputs the comment C for the content A. Moreover, the evaluation record C indicates that the evaluation user B designates the evaluation user D as the first additional evaluation user. The evaluation record C indicates that the creation user A is at a stage before changing the content A corresponding to the comment C.

(When evaluation user B requests browsing)
When the evaluation user B makes a browsing request for specifying the content A and selects the confirmation mode, the browsing request receiving unit 15 outputs a display instruction to the display control unit 21, the content identification information of the content A, and the selection instruction Are output to the display mode selection receiving unit 17. Since the user B selects the confirmation mode, the display mode selection receiving unit 17 outputs the content identification information of the content A and the extraction instruction to the extraction unit 19.

  When the extraction instruction is input, the extraction unit 19 sets the same content identification information as the content identification information of the content A in the content item from the evaluation record B and the evaluation record C stored in the HDD 115. Extract all evaluation records. Next, the extraction unit 19 adds the user identification information “user” of the evaluation user B to any of the evaluation user item, the first additional evaluation user item, and the second additional evaluation user item from the extracted evaluation records. All the evaluation records in which the same user identification information as “B” is set are extracted. Here, although the evaluation record B corresponding to the comment B and the evaluation record C corresponding to the comment C are stored in the HDD 115, the evaluation record B corresponding to the comment B is extracted and the display record corresponding to the comment C is displayed. C is not extracted.

  The display control unit 21 generates a screen for displaying the comment B set in the comment item of the evaluation record B input from the extraction unit 19 together with the content A stored in the content storage unit 13. The data is transmitted via the communication I / F unit 112 to the device operated by the login user who has requested to view the screen.

  Specifically, the comment B set in the comment item of the evaluation record B is changed to the position B in the content set in the position item of the evaluation record by the comment display unit 23 included in the display control unit 21. Displayed in association.

  Further, the reference content B set in the reference content item of the evaluation record B by the reference content display unit 27 included in the display control unit 21 is the position B in the content set in the item of the position of the evaluation record B. Are displayed in association with each other.

  Further, the change history display unit 25 included in the display control unit 21 associates the change history B set in the change history item of the evaluation record B with the position B in the content set in the position item. Is displayed.

  Further, since the related change history B that is the change history of the related content is set in the related content change history item of the evaluation record B by the history presence information display unit 31 included in the display control unit 21, the position of the evaluation record B The history presence information is displayed in association with the position B in the content set in the item.

  By specifying the confirmation mode, the evaluation user B can be prevented from browsing the comment C input by the evaluation user C. Therefore, it is determined whether or not the content A has been changed with respect to the comment B input by the evaluation user B. can do. For this reason, it is possible to efficiently check the content change.

  FIG. 12 is a fifth diagram illustrating an example of a browsing screen. Here, after the creation user A changes the content A with respect to the comment B, the browsing screen displayed when the evaluation user B requests browsing and selects the confirmation mode is shown. Referring to FIG. 12, browsing screen 301 </ b> D includes an area 311 </ b> A that displays an image of content A after change, an area 311 that displays an image of content A before change, and an operation area 351. The area 311A is different in that the area 311 includes the area 331 added by the creation user A to the area 311 and the other parts are the same. For this reason, the evaluation user B can confirm which of the contents A has been changed by the creating user A based on the comment B displayed in the area 313A by comparing the area 331A and the area 331. it can.

  The operation area 351 includes an area 352 for displaying the content identification information of the reference material, a button 353 displaying a display character, and history presence information 355 indicating a “related material changed” character. When the user indicates the button 353, the reference content specified by the content identification information set in the area 352 is displayed. Since the history presence information 355 is displayed, the evaluation user B can know that the related content has been changed. In addition, by indicating the history presence information 355, the related content before and after the change is displayed. For this reason, it is easy to confirm the change location of the related content.

(When evaluation user C requests browsing)
When the evaluation user C makes a browsing request for specifying the content A and selects the confirmation mode, the browsing request receiving unit 15 outputs a display instruction to the display control unit 21, the content identification information of the content A, and the selection instruction Are output to the display mode selection receiving unit 17. Since the user C selects the confirmation mode, the display mode selection receiving unit 17 outputs the content identification information of the content A and the extraction instruction to the extraction unit 19.

  When the extraction instruction is input, the extraction unit 19 sets the same content identification information as the content identification information of the content A in the content item from the evaluation record B and the evaluation record C stored in the HDD 115. Extract all evaluation records. Next, the extraction unit 19 is the same as the user identification information of the evaluation user B in any of the evaluation user item, the first additional evaluation user item, and the second additional evaluation user item from the extracted evaluation records. Extract all evaluation records for which user identification information is set. Here, although the evaluation record B corresponding to the comment B and the evaluation record C corresponding to the comment C are stored in the HDD 115, the evaluation record C corresponding to the comment C is extracted and the display record corresponding to the comment B is displayed. B is not extracted.

  The display control unit 21 generates a screen for displaying the comment C set in the comment item of the evaluation record C input from the extraction unit 19 together with the content A stored in the content storage unit 13.

  Specifically, the comment C set in the comment item of the evaluation record C by the comment display unit 23 provided in the display control unit 21 is the position C in the content set in the item of the position of the evaluation record C. Are displayed in association with each other.

  On the screen viewed by the evaluation user C, the change history B, the reference content B, and the change history of the related content B are not displayed. This is because the change history of the change history B, the reference content B, and the related content B is not related to the portion of the content A specified at the position C in the content where the comment C is input.

(When evaluation user D requests browsing)
When the evaluation user D makes a browsing request for specifying the content A and selects the confirmation mode, the browsing request reception unit 15 outputs a display instruction to the display control unit 21, the content identification information of the content A, and the selection instruction Are output to the display mode selection receiving unit 17. Since the user D selects the confirmation mode, the display mode selection receiving unit 17 outputs the content identification information of the content A and the extraction instruction to the extraction unit 19.

  When the extraction instruction is input, the extraction unit 19 sets the same content identification information as the content identification information of the content A in the content item from the evaluation record B and the evaluation record C stored in the HDD 115. Extract all evaluation records. Next, the extraction unit 19 further includes user identification information of the evaluation user D in the evaluation user item, the first additional evaluation user item, and the second additional evaluation user item from the extracted evaluation records. Extract all evaluation records that have the same user identification information as. Here, the user identification information “user D” of the evaluation user D is set in the item of the second additional evaluation user of the evaluation record B corresponding to the comment B, and the first addition of the evaluation record C corresponding to the comment C is performed. Since the user identification information “user D” of the evaluation user D is set in the evaluation user item, the evaluation record B corresponding to the comment B and the evaluation record C corresponding to the comment C are extracted.

  The display control unit 21 sets the comment B set in the comment item of the evaluation record B input from the extraction unit 19 and the comment item of the evaluation record C together with the content A stored in the content storage unit 13. A screen for displaying the comment C is generated.

  Specifically, the comment display unit 23 provided in the display control unit 21 corresponds to the comment B set in the comment item of the evaluation record B corresponding to the position B in the content set in the item of the evaluation record position. The comment C that is displayed and set in the comment item of the evaluation record C is displayed in association with the position C in the content set in the position item of the evaluation record.

  Further, the reference content B set in the reference content item of the evaluation record B by the reference content display unit 27 included in the display control unit 21 is the position B in the content set in the item of the position of the evaluation record B. Are displayed in association with each other.

  Further, the change history display unit 25 included in the display control unit 21 associates the change history B set in the change history item of the evaluation record B with the position B in the content set in the position item. Is displayed.

  Further, since the related change history B that is the change history of the related content is set in the related content change history item of the evaluation record B by the history presence information display unit 31 included in the display control unit 21, the position of the evaluation record B The history presence information is displayed in association with the position B in the content set in the item.

  The evaluation user D views the comment B input by the evaluation user B, the reference content B, the change history B in which the creation user A has changed the content A with respect to the comment B, and the change history of the related content. be able to. The evaluation user D can input a comment on the change of the content A and the change of the related content A input by the creation user A. For this reason, the creation user A can request the user D to evaluate the changed portion of the content A after the change.

  Further, the evaluation user D can view the comment C input by the evaluation user C. The evaluation user D can input a comment to the comment C input by the evaluation user C. For example, a comment for reinforcing the comment C, a comment for denying the comment C, or the like. For this reason, the evaluation user C can request the evaluation user D to evaluate the comment C.

  FIG. 13 is a sixth diagram illustrating an example of a browsing screen. Here, after the creation user A changes the content A with respect to the comment B, the browsing screen displayed when the evaluation user D requests browsing and selects the confirmation mode as the display mode is shown. Referring to FIG. 13, browsing screen 301E includes an area 330 for displaying the image of content A after the change, an area 301 for displaying the image of content A before the change, and an operation area 351A. The area 330 is different in that the area 330 includes an area 313A for displaying the comment of the user B in the area 301, an area 323A for displaying the comment of the user C, and an area 331 of the changed part in which the created user A changed the content A. The parts are the same. For this reason, the evaluation user D may check which of the contents A has been changed by the creating user A based on the comment B displayed in the area 313A by comparing the area 330 and the area 301. it can. Moreover, since the part of the content A corresponding to the same position as the comment C displayed in the area 323A is not changed, it can be understood that the creating user A has not changed the content A with respect to the comment C yet.

  The operation area 351A is different from the operation area 351 included in the browsing screen 301D illustrated in FIG. 12 in that an area 361 is added. The area 361 includes a message “Please comment on user A”. Thereby, it is possible to comment on the creation user A by inputting a new comment on the changed portion of the content A displayed in the area 331, for example.

  FIG. 14 is a flowchart illustrating an example of the flow of content management processing. The content management process is a process executed by CPU 111 when CPU 111 provided in MFP 100 executes a program stored in ROM 113, HDD 115, or CD-ROM 118. Referring to FIG. 14, CPU 111 determines whether or not user authentication is successful. The process waits until user authentication is successful (NO in step S01). If user authentication is successful (YES in step S01), the process proceeds to step S02. Hereinafter, the authenticated user is referred to as a login user.

  In step S02, it is determined whether content has been accepted. Accept content entered by the logged-in user. If the content is accepted, the process proceeds to step S03. If not, the process proceeds to step S04. In step S03, the content accepted in step S02 is stored in HDD 115 in association with the user identification information of the login user, and the process ends.

  On the other hand, in step S04, it is determined whether or not any content stored in HDD 115 has been accepted. If the designation is accepted, the process proceeds to step S05; otherwise, the process returns to step S02. In step S05, it is determined whether or not the login user is a creation user. Specifically, if the user identification information associated with the content specified in step S04 is the same as the user identification information of the login user, the login user is determined to be a created user. Judge as an evaluation user. If it is determined that the login user is the creation user, the process proceeds to step S06; otherwise, the process proceeds to step S08.

  In step S06, all comments are set as display comments. In HDD 115, a comment corresponding to the content specified in step S04 is stored in association with the content in HDD 116 in the evaluation user display process executed in step S13 described later. In step S06, among the comments stored in HDD 115, all of the comments associated with the content specified in step S04 are set as display comments.

  In the next step S07, the creation user display process is executed, and the process ends. Details of the creation user display process will be described later.

  On the other hand, in step S08, selection of a display mode is accepted. When the logged-in user selects either the confirmation mode or the browsing mode, the selection of the display mode is accepted. In step S09, the process branches depending on the selected display mode. If the confirmation mode is selected as the display mode, the process proceeds to step S10. If the viewing mode is selected as the display mode, the process proceeds to step S12.

  In step S10, an extraction process is executed, and the process proceeds to step S11. Although details of the extraction process will be described later, this is a process for extracting a comment input by the login user from comments stored in the HDD 115. In the next step S11, the comment extracted in step S10 is set as a display comment, and the process proceeds to step S13. On the other hand, in step S12, as in step S06, all comments are set as display comments, and the process proceeds to step S13. In step S13, the evaluation user display process is executed, and the process ends. Details of the evaluation user display process will be described later.

  FIG. 15 is a flowchart illustrating an example of the flow of extraction processing. The extraction process is a process executed in step S10 of FIG. The stage before the extraction process is executed, specifically, the evaluation user display process shown in step S13 of FIG. 14 is executed, whereby the evaluation record of the format shown in FIG. Is remembered.

  Referring to FIG. 15, in step S21, a comment associated with the evaluation user is extracted. Specifically, from the evaluation record B and the evaluation record C stored in the HDD 115, the user identification information that is the same as the user identification information of the evaluation user who is the login user identifies the evaluation record set in the item of the evaluation user Then, the comment identification information set in the comment item of the identified evaluation record is extracted.

  In the next step S22, a comment with the evaluation user as the first additional evaluation user is extracted. Specifically, from the evaluation record B and the evaluation record C stored in the HDD 115, the same user identification information as the user identification information of the evaluation user who is the login user is set in the item of the first additional evaluation user. The record is specified, and the comment identification information set in the comment item of the specified evaluation record is extracted.

  In the next step S23, a comment with the evaluation user as the second additional evaluation user is extracted, and the process returns to the content management process. Specifically, from the evaluation record B and the evaluation record C stored in the HDD 115, the same user identification information as the user identification information of the evaluation user who is the login user is set in the item of the second additional evaluation user. The record is specified, and the comment identification information set in the comment item of the specified evaluation record is extracted.

  FIG. 16 is a flowchart illustrating an example of the flow of the evaluation user display process. The evaluation user display process is a process executed in step S13 of FIG. Referring to FIG. 16, CPU 111 reads content stored in HDD 115 (step S31). Before the evaluation user display process is executed, content is designated by the login user in step S04 of FIG. In step S31, the content designated by the login user is read from HDD 115.

  In the next step S32, the first page among the plurality of pages included in the read content is set as a processing target. In the next step S33, content display processing is executed. Although details of the content display process will be described later, the content display process is a process of displaying the first page set for the process in step S32 of the content read in step S31. The display here includes a case where the display is performed on any of the PCs 200, 200A to 200E and the mobile phones 220, 220A, 220B operated by the login user.

  In step S34, it is determined whether designation of a position has been accepted. If the evaluation user who is the login user points to the position in the first page of the content displayed in step S33, the specified position is accepted as the position in the first page of the content. If the position in the content is designated, the process proceeds to step S35; otherwise, the process proceeds to step S41.

  In step S35, a comment is accepted. Accepts comments entered by an evaluation user who is a login user. In step S36, the position in the content designated in step S34 and the comment accepted in step S35 are associated with the content read in step S31. Specifically, an evaluation record having the format shown in FIG. 5 is generated, and the generated evaluation record is stored in the HDD 115. At this stage, the content identification information of the content read in step S31 is set in the content item of the evaluation record, and the user identification information of the creation user stored in association with the content is set in the creation user item. The position in the content specified in step S34 is set in the position item, the comment accepted in step S35 is set in the comment item, and the user identification information of the evaluation user who is the login user is set in the evaluation user item. Is set.

  In the next step S37, it is determined whether or not an instruction to add reference content has been accepted. When the evaluation user who is a login user inputs the content identification information of the reference content, an instruction to add the reference content is accepted. If an instruction to add reference content is accepted, the process proceeds to step S38. If not, step S38 is skipped and the process proceeds to step S39.

  In step S38, the reference content is associated with the comment received in step S35. Specifically, the received reference content is stored in HDD 115, and content identification information for identifying the stored reference content is set in the reference content item of the evaluation record generated in step S36.

  In step S39, it is determined whether an instruction to add a first evaluation user has been accepted. If the evaluation user who is the login user designates an evaluation user other than the evaluation user as the first evaluation user, an instruction to add the first additional evaluation user is accepted. If the addition instruction of the first additional evaluation user is accepted, the process proceeds to step S40. If not, step S40 is skipped and the process proceeds to step S41.

  In step S40, the first additional evaluation user is associated with the comment received in step S35. Specifically, the user identification information of the first evaluation additional value user who is instructed to add in step S39 is set in the item of the first additional evaluation user of the evaluation record.

  In step S41, it is determined whether or not related content exists. When related content is input together with content when content is input by the creation user, the related content is stored in association with the content. It is determined whether or not such related content is stored in association with the content. If related content exists, the process proceeds to step S42; otherwise, the process proceeds to step S46.

  In step S42, it is determined whether an instruction to display related content has been received. If an instruction to display related content is received from an evaluation user who is a login user, the process proceeds to step S43. If not, the process proceeds to step S44. In step S43, the related content is displayed. In the next step S44, it is determined whether or not a history display button to be displayed is instructed by executing the content display process executed in step S33. If the history display button is instructed, the process proceeds to step S45; otherwise, the process proceeds to step S46. In step S45, the related content before and after the change is displayed, and the process proceeds to step S46.

  In step S46, it is determined whether a page switching instruction has been accepted. It is determined whether or not an evaluation user who is a login user has input a page switching instruction. If a page switching instruction is accepted, the process proceeds to step S47; otherwise, the process proceeds to step S48. In step S47, the page after switching by the page switching instruction is set as a processing target, and the process returns to step S33. In step S48, it is determined whether a browsing end instruction has been accepted. It is determined whether or not an evaluation user who is a login user has input a browsing end instruction. If a browsing end instruction is accepted, the process returns to the content management process. If not, the process returns to step S34. Thereby, another comment etc. can be input continuously.

  FIG. 17 is a flowchart illustrating an example of the flow of content display processing. The content display process is a process executed in step S33 in FIG. 16 and step S73 in FIG. Referring to FIG. 17, CPU 11 displays a page set as a processing target (step S51).

  In the next step S52, it is determined whether or not there is a display comment. Here, if there is an evaluation record satisfying a predetermined condition among the evaluation records stored in the HDD 115, it is determined that a display comment exists. Hereinafter, an evaluation record that satisfies a predetermined condition is referred to as a display comment evaluation record. The predetermined condition is that the content identification information of the content read in step S31 of FIG. 16 or step S71 of FIG. 18 described later is set in the content item, and the position set in the position item Is to indicate the inside of the page displayed in step S61. If there is a display comment evaluation record, the process proceeds to step S53. If not, the process ends.

  In step S53, one of the display comments is selected as a processing target. Specifically, one is selected from the evaluation records of the display comments. In the next step S54, the position in the content corresponding to the display comment is specified. Specifically, the position in the content set in the item of the position of the evaluation record of the display comment selected in step S53 is acquired.

  In the next step S55, the display comment selected in step S53 is displayed in association with the position in the content specified in step S54. Specifically, the comment set in the comment item of the evaluation record of the display comment is displayed. For example, a comment is displayed in a form of a balloon superimposed on the content.

  In the next step S56, it is determined whether or not a content change history is associated with the display comment. If the change history is set in the change history item of the evaluation record of the display comment selected in step S53, it is determined that the content change history is associated with the display comment. If the content change history is associated with the display comment, the process proceeds to step S57; otherwise, the process proceeds to step S59.

  In step S57, the content change history is read. The change history set in the change history item of the evaluation record of the display comment is generated. In the next step S58, the content before change included in the change history read in step S57 is displayed in association with the position in the content specified in step S54. For example, the changed content is displayed in a balloon format. Thereby, the contents before and after the change can be compared.

  In the next step S59, it is determined whether or not the related content change history is associated with the display comment. If the related content change history is set in the item of the related content change history of the display comment evaluation record, it is determined that the related content change history is associated. If the related content change history is associated, the process proceeds to step S60. If not, step S60 is skipped and the process proceeds to step S61. In step S60, a history display button is displayed in association with the position in the content specified in step S54. The history display button is history presence information indicating that a related content change history exists, and is associated with a command for displaying the related content change history when the history display button is instructed.

  In step S61, it is determined whether there is a display comment to be processed next. In step S53, if there is a display comment evaluation record that is not selected as a processing target from among the display comment evaluation records, the process returns to step S53. If not, the process ends. When the content display process is terminated, if the content display process is executed during the evaluation user display process, the process returns to the evaluation user display process, or the content display process is under the creation user display process described below. Return to the creation user display process.

  FIG. 18 is a flowchart illustrating an example of the flow of the creation user display process. The creation user display process is a process executed in step S07 of FIG. Referring to FIG. 18, the content stored in HDD 115 is read (step S71). Before the creation user display process is executed, content is designated by the creation user who is the login user in step S04 of FIG. In step S <b> 71, the content designated by the creation user who is the login user is read from the HDD 115.

  In the next step S72, the first page among the plurality of pages included in the read content is set as a processing target. In the next step S73, the content display process shown in FIG. 17 is executed.

  In step S74, it is determined whether a display comment displayed by the content display process executed in step S73 has been selected. If the display comment is selected, the process proceeds to step S75. If not, the process proceeds to step S89. When the display comment is selected, among the evaluation records stored in the HDD 115, an evaluation record in which the comment identification information of the display comment is set in the comment item is set as a processing target.

  In step S75, it is determined whether or not reference content exists. If the content identification information of the reference content is set in the reference content item of the evaluation record set as the processing target, it is determined that the reference content exists. If reference content exists, the process proceeds to step S76; otherwise, the process proceeds to step S78. In step S76, it is determined whether an instruction to display reference content has been received. If the creation user who is a login user presses a button to which an instruction to display reference content is assigned, an instruction to display reference content is accepted. If an instruction to display the reference content is accepted, the process proceeds to step S77. If not, step S77 is skipped and the process proceeds to step S78. In step S77, the reference content is displayed, and the process proceeds to step S78. The reference content specified by the content identification information set in the reference content item of the evaluation record set as the processing target is read and displayed.

  In step S78, it is determined whether or not the content has been changed. It is determined whether or not the creating user who is a login user has changed the content. If it is determined that the content has been changed, the process proceeds to step S79. If not, step S79 is skipped and the process proceeds to step S80. In step S79, the change history is associated with the comment. Specifically, the change history is set in the change history item of the evaluation record set as the processing target. The change history includes changed portions before and after the change of the content corresponding to the changed portion where the content has been changed.

  In step S80, it is determined whether an instruction to add a second additional evaluation user has been accepted. If the creating user who is the login user inputs the user identification information of another user as the second additional evaluation user, the instruction to add the second additional evaluation user is accepted. If an instruction to add the second additional evaluation user is accepted, the process proceeds to step S81. If not, step S81 is skipped and the process proceeds to step S82. In step S81, the second additional evaluation user is associated with the comment. Specifically, the user identification information of the second additional evaluation user is set in the item of the second additional evaluation user of the evaluation record set as the processing target.

  In step S82, it is determined whether or not related content exists. Judgment is made based on whether or not the content read in step S71 is associated with related content. If related content exists, the process proceeds to step S83; otherwise, the process proceeds to step S89. In step S83, it is determined whether the related content has been changed. It is determined whether or not the creating user who is a login user has changed the related content. If it is determined that the related content has been changed, the process proceeds to step S84. If not, step S84 is skipped and the process proceeds to step S85. In step S84, the related content change history is associated with the comment. The related content change history is set in the related content change history item of the evaluation record set as the processing target. The change history of the related content includes a changed portion before and after the change of the related content corresponding to the changed portion in which the related content is changed.

  In step S85, it is determined whether an instruction to display related content has been received. If an instruction to display related content is received from an evaluation user who is a login user, the process proceeds to step S86; otherwise, the process proceeds to step S87. In step S86, the related content is displayed. In the next step S87, it is determined whether or not a history display button displayed by executing the content display process executed in step S73 is instructed. If the history display button is instructed, the process proceeds to step S88; otherwise, the process proceeds to step S89. In step S88, the related content before and after the change is displayed, and the process proceeds to step S89.

  In step S89, it is determined whether a page switching instruction has been accepted. It is determined whether or not the evaluation user has input a page switching instruction. If a page switching instruction is accepted, the process proceeds to step S90; otherwise, the process proceeds to step S91. In step S90, the page after being switched by the page switching instruction is set as a processing target, and the process returns to step S73. In step S91, it is determined whether a browsing end instruction has been accepted. It is determined whether or not the evaluation user inputs an instruction to end browsing. If a browsing end instruction is accepted, the process returns to the content management process. If not, the process returns to step S74. As a result, another comment can be selected, and a change history or the like corresponding to the selected comment can be set.

  As described above, MFP 100 according to the present embodiment functions as a content management apparatus. When an evaluation user designates a position in content and inputs a comment, the comment, the position designated in content and the evaluation user, Is associated, and when a part of the content is changed by the creating user, when the change history is associated with the comment specified by the creating user and the confirmation mode is selected as the display mode, browsing among one or more comments All the comments associated with the user are extracted and the content is displayed, and the comment and the change history are displayed in association with the position in the content. For this reason, the comment entered by the evaluation user himself and the change history of the user who changed the content are displayed at the same position, so it is easy to check whether the content has been changed according to the comment. Can do.
