  The network interface 112 functions as a communication unit that transmits / receives data to / from an external device such as the web server 2.

  The web server 2 is composed of a personal computer or the like. In this embodiment, the web server 2 issues a one-time job ticket in response to a request from the MFP 1 or the like, and executes a web service that stores image data or the like transmitted from the MFP 1.

  Next, the operation of the MFP 1 when the user uses the web service by the internal web server unit 108 and the web service by the external web server 2 from the MFP 1 shown in FIG. 1 will be described using the screen flow of FIG. In the following description, the web service by the MFP 1 is also called an MFP service or a first web service, and the web service by the web server 2 is also called a second web service.

  Based on the user operation on the menu screen D1 displayed on the display unit 104a, the MFP 1 accesses the web service in the own apparatus from the web browser 107, and uses the one-time job ticket request screen D11 which is a web page as a caller screen. It is displayed on the display unit 104a. When the MFP 1 accesses the external web server 2 based on a user operation on the request screen D11, a login screen D21 that is a web page by the second web service provided by the web server 2 is displayed. That is, the login screen D21 on the second web service side is called from the request screen D11 for the one-time job ticket on the MFP side. The web service login screen D21 is displayed in a layer different from the one-time job ticket request screen D11 on the MFP side.

  When the user logs in to the web server 2 through the web service login screen D21, the web service login screen D21 transits to a one-time job ticket issuance screen D22 based on the content of the second web service, and thereafter the one-time job ticket. Transition to the issue completion screen D23.

  In this embodiment, as described above, the web service login screen D21 on the second web service side is displayed in a layer different from the one-time job ticket request screen D11 on the MFP service side, and further, the web service login screen D21. To the 1-time job ticket issuance screen D22, and further to the 1-time job ticket issuance completion screen D23, the web service login screen D21 on the second web service side, the 1-time job ticket issuance screen D22, and the 1-time job When the ticket issuance completion screen D23 is displayed, the user cannot operate the one-time job ticket request screen D11 on the MFP service side. That is, the operation of the one-time job ticket request screen D11 is prohibited.

  Accordingly, it is possible to prevent an erroneous operation caused by the user operating the one-time job ticket request screen D11 on the MFP service side in a state where the issuance of the one-time job ticket is not completed as in the prior art.

  FIG. 3 is an image diagram when the second web service-side callee screen is displayed in a separate layer with respect to the one-time job ticket request screen D11 (caller screen).

  As shown in FIG. 3A, the callee screen 201 is called from the caller screen 200 displayed on the display unit 104a and displayed in a layer as shown in FIG. 3B. For the screen call, an original HTML (HyperText Markup Language) tag or JavaScript (registered trademark) function may be prepared in advance, or a uniform layer display may be performed by calling a normal tab or window. When the screen transition on the callee screen is completed, it is removed from the layer (removed from the memory) or placed behind the caller screen 200 as shown in FIG.

  In the example of FIG. 3, there is only one call destination screen, but the call source screen may call a plurality of call destination screens to perform display control.

  After the one-time job ticket issuance completion screen D23 is displayed, processing for displaying the one-time job ticket request screen D11 on the MFP service side on the display unit 104a so as to be operable is performed. This process is executed when a preset display switching condition is satisfied.

  The display switching condition is a condition where the callee screen is expected to have transitioned to the final screen. For example, the following conditions can be cited.

  First, a URL (Uniform Resource Locator) screen designated in advance is displayed on the callee screen. For example, the URL of the web service login screen D21 is “http: //ext-web/login.html”, and the URL of the one-time job ticket issue screen D22 is “http: //ext-web/issue-job-ticket.html”. When the URL of the one-time job ticket issuance completion screen D23 is “http: //ext-web/complete-job-ticket.html”, the one-time job ticket issuance completion screen D23 that is the final screen is identified. Can do. By designating the URL of the screen in advance, the web browser 107 determines that the display switching condition is satisfied by displaying the one-time job ticket issue completion screen D23. Since the final screen may change depending on the situation in the middle of the screen, such as when the final screen changes between a success screen and a failure screen by executing some processing, a plurality of URLs can be specified. In this case, since there is a case where subsequent processing may be changed depending on success or failure, it may be notified to the calling MFP service side which URL corresponds.

  Another example of the display switching condition is a case where an HTML screen including character string data designated in advance is displayed on the call destination screen. For example, there is a comment (for example, This page shows the status of completion of job ticket) including the characters “completion of job ticket” in HTML.

  As another example of the display switching condition, there can be mentioned a case where an HTML screen that does not include character string data designated in advance is displayed on the call destination screen. For example, there is a case where a comment including “This page is included in the process of job ticket” is not included in the HTML.

  As another example of the display switching condition, there may be a case where there is no operation button for transitioning to the next screen such as a “submit” button on the call destination screen. For example, if the form action method such as "form action =" cgi-bin / abc.cgi "method =" post "" is not included, or the input type such as "input type =" submit "value =" OK "" And “submit” is not included.

  As another example of the display switching condition, a case where there is no link to another screen on the callee screen can be cited. For example, a link method such as “a href =" http: //ext-web/next.html "" or the next screen "/ a" is not included.

  If at least one of the display switching conditions as described above is satisfied, the MFP 1 is operable to display the one-time job ticket request screen D11, which is a caller screen on the MFP service side, on the display unit 104a. Execute the process.

  As an example of this processing, as shown in FIG. 4, a “close” button 300 is displayed on the one-time job ticket issue completion screen D23 which is the final screen. When the user presses the “close” button 300, the call destination screen is closed and the one-time job ticket request screen D11 is displayed to be operable.

  As another processing example, as shown in FIG. 5, the one-time job ticket issuance completion screen D23 is automatically closed within a few seconds after the one-time job ticket issuance completion screen D23, which is the final screen, is displayed. The ticket request screen D11 may be displayed so as to be operable. Alternatively, a message prompting the user to touch the one-time job ticket issuance completion screen D23 may be displayed, and the one-time job ticket request screen D11 may be displayed to be operable when touched.

  Further, from the caller screen 200 shown in FIG. 6A, a third web service by a web server is called in addition to the second web service, as shown in FIG. The web service-side callee screen 201 may be displayed as a layer on the front. The call destination screen 202 on the third web service side is not hidden and displayed below the call destination screen 201 on the second web service side, like the call source screen 200 on the MFP service side. In this case, when the display switching condition is satisfied for the call destination screen 201 on the second web service side, the system control unit 106 notifies the program operating the web browser 107 to that effect. Then, which layer is to be displayed is selected according to the application provided by the web server unit 108 and the CGI processing unit 109, and either the caller screen 200 on the MFP service side or the callee screen 202 on the third web service side is selected. Is displayed. For example, as shown in FIG. 6C, the second web service side callee screen 201 is hidden in the lower layer of the MFP service side caller screen 200, and the third web service side callee screen 202 is displayed. indicate.

  The same applies when three or more web services are called from the caller screen 200 on the MFP service side.

  Returning to FIG. 2, after the display is switched from the one-time job ticket issuance completion screen D22 to the one-time job ticket request screen D11 which is the caller screen on the MFP service side, the one-time job ticket request screen D11 is displayed. When the second web service confirms that the one-time job ticket has been issued by operating, the display screen transits to the one-time job ticket confirmation screen D12. After confirmation, the user transitions the one-time job ticket confirmation screen D12 to the scan setting / transmission screen D13.

  When the user operates the scan setting / transmission screen D13 to perform scan settings and presses a transmission button, the image data of the original read by the scanner unit 110 is transmitted to the web server 2 and stored.

  FIG. 7 is a flowchart showing the operation of the MFP 1 as described above. This operation is executed when the CPU 101 of the MFP 1 operates based on an operation program or an application.

  In step S01, after displaying the web page which is the screen of the caller (MFP service side), in step S02, when the webpage of the caller instructs the browser to display another webpage, the layer display is displayed in step S03. Determine whether the format is an instruction.

  If it is a web page of another web service, it is an instruction in the layer display format (YES in step S03). After the call destination screen is displayed in another layer in step S04, the call destination screen is displayed in step S05. It is determined whether the display switching condition is satisfied.

  If the display switching condition is not satisfied (NO in step S05), the process stays in step S05 until it is satisfied. If the display switching condition is satisfied (YES in step S05), control is transferred to the caller screen in step S06. That is, a process for displaying the caller screen in an operable manner is performed, and the caller screen is displayed.

  If it is not the display in the layer format in step S03 (NO in step S03), it is displayed on the normal tabbed screen or window screen in step S07.

  FIG. 8 is a view for explaining another embodiment of the present invention. This embodiment shows a screen flow in a case where processing is performed by calling other web services from different screens of one web service and returning to the caller screen after the processing is completed.

  Specifically, for the web service A, the screen A-1 is opened, and the screen A-1 is changed to the screen A-2 and further to the screen A-3. The web service B is called from the screen A-2, the screen B-1 is displayed as a layer, the screen B-2 is changed to a screen B-2, and then the call screen A-2 of the web service A is returned.

  In the web service A, the screen A-2 is changed to the screen A-3. The web service C is called from the screen A-3, the screen C-1 is displayed as a layer, the screen C-2 is changed to a screen C-2, and then the web service A caller screen A-3 is returned.

  In this embodiment, a workflow for calling another web service B and web service C from the caller screen of the web service A as described above to execute processing can be set and registered in advance via the setting screen. After the setting / registration, the web service is called according to the set workflow and the process is executed.

  In the embodiment described above, the callee screen is displayed in a different layer from the caller screen, but the callee screen and the caller screen are not in separate layers, and a tab for opening the screen is added as shown in FIG. It may be displayed as a screen. In the example of FIG. 9, the screen D30 of the D tab 304 is the call destination screen. In the example of FIG. 9, the A tab 301, the B tab 302, and the C tab 303 are hidden behind the screen D30 of the D tab 304. These screens are operated by tabs to prevent erroneous operations.
