When an error of the print function is recorded in the error information 35 managed by the system control unit 30, the screen generation unit 31a displays, for example, a Web page as shown in FIG. 6B as an error screen corresponding to the error. G21 is generated. At this time, the screen generation unit 31a may create the Web page G21 that is an error screen at the same address as the Web page G20 that is an operation screen, or may create it at a different address. When creating the same address, the screen generation unit 31a performs processing for replacing the Web page G20 set at the address 42 shown in FIG. 4 with the Web page G21 of the error screen when an error occurs in the print function. Become.

  FIG. 7 is a diagram illustrating an example of a Web page related to the FAX function generated by the screen generation unit 31a. FIG. 7A shows a Web page G30 generated as an operation screen for the FAX function, and FIG. 7B shows a Web page G31 generated as an error screen when an error occurs in the FAX function. An example is shown. For example, when the IWS unit 31 is activated, the screen generation unit 31a creates a Web page G30 as illustrated in FIG. 7A at the address 43 illustrated in FIG. When an error of the FAX function is recorded in the error information 35 managed by the system control unit 30, the screen generation unit 31a displays, for example, a Web page as illustrated in FIG. 7B as an error screen corresponding to the error. G31 is generated. At this time, the screen generation unit 31a may create the web page G31 that is an error screen at the same address as the web page G30 that is the operation screen, or may create it at a different address. When creating the same address, the screen generation unit 31a performs processing for replacing the Web page G30 set at the address 43 shown in FIG. 4 with the Web page G31 on the error screen when an error occurs in the FAX function. Become.

  The screen generator 31a holds screen information 36 as shown in FIG. The screen information 36 is information that is stored and managed in a predetermined storage area such as the memory 11, for example. As described above, an error occurs in any of the scan function, print function, and FAX function, and an error screen is displayed. When created, information about the error screen is recorded.

  FIG. 8 is a diagram showing an example of the screen information 36. As shown in FIGS. 8A and 8B, the screen information 36 includes screen information 36a related to the scan function, screen information 36b related to the print function, and screen information 36c related to the FAX function. Each screen information 36a, 36b, 36c includes an error flag and an error screen URL. For example, when no error has occurred in the scan function, as shown in FIG. 8A, the error flag of the screen information 36a related to the scan function is set to “0”, and no information is recorded in the error screen URL. It becomes a state. On the other hand, when an error occurs in the scan function, the screen generator 31a sets the error flag to “1” as shown in FIG. 8B, and sets the error screen address corresponding to the error to the error screen. Record in URL. The same applies when an error occurs in the print function or FAX function. The error flag is error occurrence information indicating the occurrence of an error, and is represented by 1-bit information, for example.

  Next, the browser 32 performs processing for accessing the Web server 2 via the network communication interface 12, acquiring a Web page provided by the Web server 2, and displaying the Web page on the display unit 14a. This browser 32 is a tab browser that can individually start a plurality of display tabs, accesses addresses set individually for each display tab, and displays on each display tab from each address. This is a configuration capable of acquiring a Web page for doing this.

  FIG. 9 is a block diagram illustrating an example of a detailed functional configuration of the browser 32. As shown in FIG. 9, the browser 32 includes a first display tab control unit 32a, a function specifying unit 32b, and a second display tab control unit 32c.

  The first display tab control unit 32a is a processing unit that accesses an address designated by the user, acquires a Web page GA for display on the first display tab from the address, and causes the display unit 14a to display the web page GA. That is, the first display tab control unit 32a operates as the browser 32 is activated, and activates the first display tab among the plurality of display tabs. Then, the first display tab control unit 32a accesses the external Web server 2 via the network communication interface 12 based on the address input to the operation panel 14 by the user, and acquires the Web page GA from the Web server 2. Then, the web page GA acquired from the web server 2 is output to the display unit 14a of the operation panel 14 while being displayed on the first display tab. The web page GA is a web page acquired from an external address.

  When the first display tab control unit 32a acquires the Web page GA from the external Web server 2, the browser 32 causes the function specifying unit 32b to function. The function specifying unit 32b analyzes the Web page GA acquired from the external Web server 2 to determine which function of the scan function, the print function, and the FAX function is the Web page GA. Is identified.

  For example, when the Web page GA acquired from the Web server 2 is a page that can upload a file such as document data, the Web page GA includes a reference button for selecting an upload file as content. It is. When the web page GA acquired from the web server 2 is a page on which a file can be downloaded, the web page GA includes a download button or the like for instructing the execution start of the download as content. .

  Therefore, the function specifying unit 32b specifies the function based on the content included in the Web page GA acquired from the Web server 2. More specifically, since the image data obtained by the scan function can be uploaded to any page where a file can be uploaded, the function specifying unit 32b scans as a function related to the Web page GA. Identify functions. Further, since the downloaded file can be printed out by the print function as long as the file can be downloaded, the function specifying unit 32b specifies the print function as a function related to the Web page GA. . In the case of a downloadable Web page GA, not only the print function but also a FAX function may be specified.

  Further, the Web page GA acquired from the Web server 2 may have a specific file format such as a PDF file. When the Web page GA itself is in a specific file format such as a PDF file, the file can be printed out by a print function. Therefore, when the function cannot be specified from the content included in the Web page GA acquired from the Web server 2, the function specifying unit 32b specifies the function based on the file format of the Web page GA itself.

  The second display tab control unit 32c is a Web page related to the function specified by the function specifying unit 32b, acquires the Web page GB generated by the screen generation unit 31a of the IWS unit 31, and sets the Web page GB as the first page. 2 is output to the display unit 14a of the operation panel 14 while being displayed on the display tab 2. The web page GB is a web page acquired from the IWS unit 31 and corresponds to any of the web pages G10, G11, G20, G21, G30, and G31 described above.

  For example, when the function specified by the function specifying unit 32b is a print function, the second display tab control unit 32c accesses the address 42 corresponding to the print function set by the IWS unit 31, and prints from the address 42. A Web page GB related to the function is acquired. Then, the second display tab control unit 32c outputs the Web page GB related to the print function to the display unit 14a as being displayed on a second display tab different from the first display tab.

  When a plurality of display tabs are activated in the browser 32, the display unit 14a displays, for example, the plurality of display tabs in a stacked state so that the user can visually recognize the contents of the display tab located at the forefront. .

  FIG. 10 is a diagram illustrating an example of a screen displayed on the display unit 14 a by the browser 32. When the browser 32 is activated in the CPU 10, a screen related to the browser function is displayed by the browser 32 on the display unit 14a. On this screen, as shown in FIG. 10, the first display tab 51 and the second display tab 52 are displayed in a state where they overlap each other. In the illustrated example, the first display tab 51 is located on the front side of the second display tab 52, and the display area R1 of the first display tab 51 is visible. An address display column 50 is provided above the plurality of display tabs 51 and 52. In the address display field 50, the address of the Web page displayed on the display tab that is visible is displayed.

  For example, when the user selects the browser function by operating the operation panel 14 and activates the browser 32, the first display tab 51 is first displayed on the display unit 14a. When the user operates the operation panel 14 to input an external address for accessing the Web server 2 in the address display field 50, the browser 32 accesses the Web server 2 via the network communication interface 12. Then, the Web page GA to be displayed on the first display tab 51 is acquired from the Web server 2 and the Web page GA is displayed in the display area R1 of the first display tab 51.

  Further, the browser 32 analyzes the Web page GA displayed on the first display tab 51, thereby specifying a function related to the Web page GA. At this time, if the specified function is a print function, the browser 32 activates the second display tab 52 as shown in FIG. Then, the browser 32 acquires the Web page GB related to the print function generated in the IWS unit 31 and displays the Web page GB on the display unit 14a as being displayed on the second display tab 52. When the Web page GA displayed on the first display tab 51 is not related to the print function but is related to the scan function or the FAX function, the second display tab 52 is generated in the IWS unit 31. A Web page GB related to the scan function or the FAX function is displayed.

  As described above, the browser 32 acquires the Web page GA from the external address designated by the user and displays the Web page GA on the first display tab 51, so that the function related to the Web page GA is specified and specified. Only the web page GB related to the function is acquired from the IWS unit 31 and displayed on the second display tab 52.

  Further, the browser 32 obtains a Web page GB related to the specified function from the IWS unit 31 and displays it on the second display tab 52, and then periodically accesses the screen information 36 held in the IWS unit 31. Monitor whether an error screen related to the specified function has been generated. At this time, the browser 32 accesses only the screen information corresponding to the specified function among the plurality of screen information 36a, 36b, 36c included in the screen information 36, and whether or not “1” is set in the error flag. Determine. For example, as shown in FIG. 10, when the Web page GB related to the print function is displayed on the second display tab 52, the browser 32 accesses the screen information 36b related to the print function, and the error flag is “1”. Is determined. As a result, when the error flag is set to “1” and an error screen related to the specified function is generated, the browser 32 acquires a Web page related to the error screen from the address recorded in the error screen URL. Then, the Web page related to the error screen is displayed on the second display tab 52.

  As described above, when the browser 32 acquires the Web page GA to be displayed on the display unit 14a from the external address, the function related to the acquired Web page GA from the plurality of functions including the scan function, the print function, and the FAX function. And monitor whether or not an error has occurred only for the specified function. If an error has occurred with respect to the specified function, a web page GB corresponding to an error screen indicating the content of the error is automatically acquired from the IWS unit 31, and the first display tab that the user is browsing The web page GB of the error screen is displayed on the second display tab 52 different from 51.

  Next, a specific operation procedure when the system control unit 30, the IWS unit 31, and the browser 32 function in the CPU 10 of the image processing apparatus 1 will be described.

  First, FIG. 11 is a flowchart illustrating an example of a processing procedure performed by the system control unit 30. When the operating system 20 is activated in the CPU 10 and the system control unit 30 functions, the system control unit 30 periodically executes processing based on the flowchart shown in FIG. 11 at regular time intervals.

  When starting this process, the system control unit 30 first determines whether an error is detected in any of the error detection units 15a, 16a, and 17a provided in the scanner unit 15, the printer unit 16, and the FAX unit 17, respectively. Is determined (step S10). When an error is detected in any of the error detection units 15a, 16a, and 17a (YES in step S10), the system control unit 30 acquires detailed information regarding the error (step S11) and records it in the error information 35. (Step S12). If no error is detected in any of the error detection units 15a, 16a, and 17a (NO in step S10), the processes in steps S11 and S12 are skipped.

  Next, the system control unit 30 determines whether or not the error detected in any of the error detection units 15a, 16a, and 17a has been resolved (step S13). As a result, if it is determined that the error has been resolved (YES in step S13), the system control unit 30 records that the error has been resolved in the error information 35 (step S14). If errors detected in the past have not yet been resolved (NO in step S13), the process in step S14 is skipped.

  By performing the above processing periodically, the error information 35 managed by the system control unit 30 includes error occurrence status and resolution status in each of the scanner unit 15, the printer unit 16, and the FAX unit 17. Are sequentially recorded. The system control unit 30 executes various processes other than the above, but the description thereof is omitted.

  Next, FIG. 12 is a flowchart illustrating an example of a processing procedure performed by the IWS unit 31. When the application program 21 is further activated with the operating system 20 activated in the CPU 10 and the IWS unit 31 functions, the IWS unit 31 executes processing based on the flowchart shown in FIG.

  When this process is started, the IWS unit 31 creates an operation screen related to the scan function of the image processing apparatus 1 as a Web page G10 at a predetermined address 41 (step S20). Similarly, the IWS unit 31 creates an operation screen related to the print function and an operation screen related to the FAX function as Web pages G20 and G30 at predetermined addresses 42 and 43, respectively (steps S21 and S22). Then, the IWS unit 31 generates screen information 36 (step S23). At this time, in the screen information 36a, 36b, 36c corresponding to each function, “0” indicating that no error has occurred is set as a default value in the error flag, and nothing is recorded in the error screen URL.

  Next, the IWS unit 31 refers to the error information 35 managed by the system control unit 30 (step S24), and determines whether an error has occurred in any of the scanner unit 15, the printer unit 16, and the FAX unit 17. Judgment is made (step S25). If the occurrence of an error is recorded in the error information 35 (YES in step S25), the IWS unit 31 acquires detailed information about the error from the error information 35 (step S26), and the error recorded in the error information 35 Are classified by function (step S27). Then, the IWS unit 31 generates an error screen corresponding to the classified error as a Web page for each function (step S28). At this time, the Web page of the error screen may be generated at the same address as the Web page of the operation screen, or may be generated at a different address. Then, the IWS unit 31 updates the screen information 36 (step S29). That is, in the screen information 36a, 36b, 36c corresponding to the function in which the error is classified, the error flag is set to “1”, and the error screen URL is recorded with an address for accessing the web page of the error screen. .

  However, when the web page of the error screen is generated at the same address as the web page of the operation screen and the web page is updated, the browser 32 can acquire the web page of the error screen from the same address. Therefore, in such a case, when the IWS unit 31 updates the screen information 36, it is not necessary to record an address for the error screen URL of the screen information 36a, 36b, 36c. May be omitted.

  If NO is determined in step S25, the processes in steps S26 to S29 described above are skipped.

  Next, the IWS unit 31 determines whether or not the error recorded in the error information 35 has been resolved (step S30). As a result, if it is determined that the error has been resolved (YES in step S30), the IWS unit 31 deletes the web page of the error screen (step S31), resets the error flag to “0”, and stores the screen information 36. Update (step S32). At this time, the address recorded in the error screen URL may be deleted. On the other hand, when the error recorded in the error information 35 has not yet been resolved (NO in step S30), the processes in steps S31 and S32 are skipped. Thereafter, the IWS unit 31 repeatedly executes the processes of steps S24 to S32 described above.

  When the occurrence of an error is recorded in the error information 35 in the system control unit 30 by the IWS unit 31 performing the above processing, an error screen web page corresponding to the error is created at a different address for each function. Will come to be. Further, when a web page of an error screen is generated by the IWS unit 31, the screen information 36 is updated accordingly.

  Next, FIG. 13 and FIG. 14 are flowcharts showing an example of processing procedures performed by the browser 32. When the browser system 22 is further activated while the operating system 20 and the application program 21 are activated in the CPU 10, and the browser 32 functions, the browser 32 executes processing based on the flowcharts shown in FIGS.

  When starting this process, the browser 32 performs a first display tab display process (step S40). In the first display tab display process, the first display tab 51 is activated and displayed on the display unit 14a. That is, processing for accessing the Web server 2 based on the external address designated by the user to acquire the Web page GA and displaying the Web page GA on the display unit 14 a using the first display tab 51 is performed.

  Next, the browser 32 executes a function specifying process (step S41). In this function specifying process, the browser 32 analyzes the Web page GA acquired from the external address by the first display tab table process, and specifies a function related to the Web page GA. Thereby, at least one of the scan function, the print function, and the FAX function is specified as a function related to the Web page GA.

  Next, the browser 32 acquires the web page GB of the operation screen corresponding to the function specified by the function specifying process (step S41) from the IWS unit 31 (step S42), and performs the second display tab display process (step S43). ). In the second display tab display process, a process of starting the second display tab 52 and displaying it on the display unit 14a is performed. That is, a process of displaying the Web page GB acquired in step S42 on the display unit 14a by the second display tab 52 is performed. Accordingly, on the second display tab 52, an operation screen for functions related to the Web page GA displayed on the first display tab 51 is displayed. By performing the processing so far, the Web page GA acquired from the external address is displayed on the first display tab 51 and the Web page GB acquired from the IWS unit 31 is displayed on the display unit 14a. The state is displayed on the display tab 52.

  The browser 32 executes display update processing (step S44). This display update process is repeatedly executed until the user instructs the end of the browser (step S45).

  FIG. 14 is a flowchart showing an example of a detailed processing procedure of the display update process (step S44). When starting this process, the browser 32 first determines whether or not there has been an instruction to update the Web page GA displayed on the first display tab 51 (step S50). When there is an instruction to update the web page GA (YES in step S50), the browser 32 obtains the web page GA again from the external address designated by the user, and the first display tab 51 is based on the web page GA. The display state is updated (step S51). Then, the browser 32 executes the function specifying process again (step S52). This function specifying process is the same as that in step S41 described above, and a function related to the Web page GA acquired from the external address is specified again. Then, the browser 32 acquires the Web page GB of the operation screen corresponding to the function specified by the function specifying process (step S52) from the IWS unit 31 (step S53), and updates the display on the second display tab 52. (Step S54). If it is determined in step S50 that there is no instruction to update the web page GA (NO in step S50), the processes in steps S51 to S54 are skipped.

  Next, the browser 32 accesses the screen information 36 managed by the IWS unit 31, and confirms an error flag corresponding to the function specified by the function specifying process of step S42 or S53 (step S55). Then, it is determined whether or not an error screen corresponding to the specified function has been generated (step S56). If an error screen has been generated (YES in step S56), the web page GB of the error screen corresponding to the error. Is acquired from the IWS unit 31 (step S57). Then, the browser 32 displays the acquired error page Web page GB on the second display tab 52 (step S58).

  In step S58, for example, the browser 32 updates the Web page to be displayed on the second display tab 52 already displayed on the display unit 14a by replacing the Web page on the operation screen with the Web page on the error screen. . However, it is not necessarily limited to such a display mode, and the error screen may be displayed in another display mode. For example, another display tab different from the second display tab 52 displaying the operation page Web page may be further activated, and the error page Web page may be displayed on the display tab. In this case, a plurality of second display tabs 52 are displayed on the display unit 14a.

  If it is determined in step S56 that an error screen corresponding to the specified function has not been generated (NO in step S56), the processes in steps S57 and S58 are skipped.

  In step S59, the browser 32 accesses the screen information 36 managed by the IWS unit 31, and determines whether or not the error corresponding to the error screen displayed on the second display tab 52 has been resolved. Judgment is made (step S59). Here, if the error flag is reset to “0”, it is determined that the error has been resolved. If the error has been resolved (YES in step S59), the browser 32 deletes the web page of the error screen displayed on the second display tab 52 (step S60). At this time, the browser 32 returns to the state where the Web page of the operation screen is displayed on the second display tab 52 (step S60). If it is determined in step S59 that the error has not been resolved (NO in step S59), the process in step S60 is skipped. Then, the display update process (step S44) ends.

  When the browser 32 performs the above-described processing, the first display tab 51 can display the Web page GA acquired from the Web server 2 and the second display tab 52 includes the first page. The Web page GB related to the function related to the Web page GA displayed on the display tab 51 can be acquired from the IWS unit 31 and displayed.

  In the processing described above, the browser 32 periodically checks whether an error screen has been generated for the function related to the Web page GA displayed on the first display tab 51, and the error screen is generated. If so, the corresponding Web page is automatically acquired and displayed on the second display tab 52. For this reason, even if an error occurs in any of the scanner unit 15, the printer unit 16, and the FAX unit 17 in the image processing apparatus 1, the activation state of the browser 32 does not end. In this case, if the error that has occurred in the image processing apparatus 1 is an error relating to a function related to the Web page GA displayed on the first display tab 51, the browser 32 displays an error screen Web corresponding to the error. The page is automatically acquired and displayed on the second display tab 52. On the other hand, if the error that occurred in the image processing apparatus 1 is an error related to a function not related to the Web page GA displayed on the first display tab 51, the browser 32 automatically acquires the Web page of the error screen. Without doing so, the previous display state is continued.

  That is, the browser 32 according to the present embodiment does not monitor the occurrence of all errors that may occur in the image processing apparatus 1 but functions related to the Web page GA displayed on the first display tab 51. It only monitors whether an error has occurred. Therefore, the processing load on the browser 32 can be reduced and the occupation ratio of the browser 32 in the CPU 10 and the memory 11 can be reduced as compared with the case where all error occurrence states that can occur in the image processing apparatus 1 are monitored. It is like that.

  Next, screen transitions displayed on the display unit 14a by the browser 32 as described above will be described. FIGS. 15 to 17 are diagrams showing examples of screen transitions by the browser 32.

  First, the screen example shown in FIG. 15A shows a state in which the browser 32 acquires the Web page GA related to file upload from the Web server 2 and displays it on the first display tab 51. In this state, when the web page GA displayed on the first display tab 51 is analyzed, it is detected that the reference button B1 is included as content in the web page GA. Therefore, the browser 32 specifies that the function related to the Web page GA displayed on the first display tab 51 is the scan function. As a result, in the screen example shown in FIG. 15A, the web page GB related to the scan function is acquired from the IWS unit 31 by the browser 32 and displayed on the second display tab 52.

  In the display state shown in FIG. 15A, the browser 32 periodically accesses the screen information 36 of the IWS unit 31 to check whether an error screen related to the scan function has been generated. When performing this confirmation, the browser 32 displays the second display tab 52 on the tab portion of the second display tab 52 displaying the screen corresponding to the scan function, for example, as shown in FIG. Displays that update processing is being performed. With such a display mode, the user who is browsing the first display tab 51 can grasp that the screen update related to the scan function is being confirmed on the second display tab 52.

  When the browser 32 detects that an error screen related to the scan function has been generated, the browser 32 automatically acquires the Web page GB related to the error screen from the IWS unit 31, and displays the second display as shown in FIG. Display on tab 52. In the state shown in FIG. 16A, since the second display tab 52 is located on the back side of the first display tab 51, the web page GB relating to the error screen automatically acquired from the IWS unit 31 is not visible. It has become. Therefore, the browser 32 displays a simple error message on the tab portion of the second display tab 52 and alerts the user by blinking the tab portion.

  When the user operates the tab portion of the second display tab 52, as shown in FIG. 16B, the second display tab 52 is displayed in the foreground, and the display area R2 of the second display tab 52 is displayed. It becomes visible. In this display area R2, a web page GB of an error screen related to the scan function automatically acquired by the browser 32 from the IWS unit 31 is displayed. Therefore, for the user, when uploading an image data file obtained by scanning a document using the scan function, an appropriate countermeasure can be taken based on the error content displayed on the second display tab 52. The first display tab 51 that is hidden behind the second display tab 52 maintains the previous display state as it is.

  Then, after the user takes appropriate measures to eliminate the error, and operates the tab portion of the first display tab 51, the first display tab 51 is again displayed in the foreground on the display unit 14a. Become. At this time, since the previous display state is held as it is in the first display tab 51, the user can continue the operation from the state immediately before the second display tab 52 is displayed in the foreground. .

  Next, FIG. 17 shows a mode in which a plurality of display tabs 52 a and 52 b are displayed as the second display tab 52. The screen example shown in FIG. 17A shows a state in which the browser 32 acquires the Web page GA related to file upload from the Web server 2 and displays it on the first display tab 51. In this state, when the analysis of the Web page GA displayed on the first display tab 51 is performed, the scan function is specified as a function related to the Web page GA. As a result, in the screen example shown in FIG. 17A, the web page related to the operation screen of the scan function is acquired from the IWS unit 31 by the browser 32 and displayed on the second display tab 52a. On the second display tab 52b, a Web page related to the error screen of the scan function is displayed. Such a display mode is applied, for example, when the address where the error screen is created is different from the address of the operation screen.

  When the browser 32 accesses the screen information 36 of the IWS unit 31 and checks whether or not an error screen related to the scan function has been generated, as shown in FIG. It is displayed that the update process is being performed on the tab portion of the second display tab 52b. When the browser 32 detects that an error screen related to the scan function has been generated, the browser 32 automatically acquires the Web page GB related to the error screen from the IWS unit 31, and displays the second display as shown in FIG. Display on the tab 52b. In the state shown in FIG. 17B, since the second display tab 52 is located on the back side of the first display tab 51, the web page GB relating to the error screen automatically acquired from the IWS unit 31 is not visible. It has become. Therefore, the browser 32 displays a simple error message on the tab portion of the second display tab 52 and alerts the user by blinking the tab portion. In the case of such a display mode, when the error screen related to the scan function is not generated in the IWS unit 31, even if the second display tab 52b is displayed in the foreground, nothing is displayed in the display area R2. It will not be displayed.
