  Next, software development in the above system will be described.

  FIG. 2 is a flowchart showing a development procedure in the software development system in FIG.

  First, in the development apparatus 1, the development platform 32 is activated.

  Then, the web page data 22 is edited by a text editor in the development platform 32 in accordance with a user operation on the input device 15 (step S1).

  Next, when a user operation for causing the web browser 33 to interpret the web page data 22 is detected by the input device 15, the controller 41 calls the web browser program 21, starts the web browser 33, and the web page The data 22 is interpreted (step S2). When a command for operating the internal device of the image forming apparatus 2 in the script of the web page data 22 is executed, the web browser 33 transmits an HTTP request to the web server 73 of the image forming apparatus 2 according to the script. A response including the operation result is received. The web browser 33 executes subsequent processing using the operation result in accordance with the web page data 22.

  In this way, the web page data 22 is experimentally interpreted by the web browser 33 in the development device 1.

  Thereafter, the user determines whether to install the web page data 22 into the image forming apparatus 2 (step S3).

  When the user determines that the web page data 22 is completed, the user performs an operation for installing the web page data 22 in the image forming apparatus 2. When detecting the operation, the controller 41 transmits the web page data 22 to the image forming apparatus 2 together with the HTTP request (step S4). In the image forming apparatus 2, the web server 73 receives the web page data 22 via the communication device 53 and the communication unit 72 and stores it in the storage device 54.

  In this way, the completed web page data 65 is stored in the image forming apparatus 2.

  In the script of the web page data 65 stored in the storage device 54 in this way, a command for transmitting an HTTP request to the web server 73 in order to operate the internal device as described above is described. Therefore, when the web page data 65 is interpreted by the web browser 75 of the image forming apparatus 2, an HTTP request is transmitted from the web browser 75 to the web server 73, and the interface 74 is controlled in response to the HTTP request. The unit 72 is activated, and the control unit 72 causes the internal device to execute the operation specified by the HTTP request. Thereafter, a response including the operation result is transmitted from the web server 73 to the web browser 75.

  When the image forming apparatus 2 is accessed by the web browser 92 of the user terminal device 3, the web browser 92 transmits a transmission request for the web page data 65 to the web server 73. This transmission request is an HTTP request. When the web server 73 receives a transmission request for the web page data 65 developed by the development device 1 via the communication device 53 and the communication unit 71, the web server 73 reads the web page data 65 and transmits it to the web browser 92. When receiving the web page data 65, the web browser 92 of the user terminal device 3 starts to interpret the web page data 65. Then, when a command for transmitting an HTTP request to the web server 73 for operating the internal device is interpreted as described above, the web browser 92 transmits the HTTP request to the web server 73. As a result, the interface 74 activates the control unit 72 in response to the HTTP request, and the control unit 72 causes the internal device to execute the operation specified by the HTTP request. Thereafter, a response including the operation result is transmitted from the web server 73 to the web browser 92.

  As described above, when the web page data 65 is used in the image forming apparatus 2 as in the development, the web server 73 and the interface 74 are used to operate the internal apparatus.

  As described above, the web page data 65 including the script is developed, installed, and interpreted by the web browsers 75 and 92.

  Here, the details of the operation of the development apparatus 1 in the software development stage in step S2 described above will be described. FIG. 3 is a flowchart for explaining the operation of the development apparatus 1 at the software development stage in the system shown in FIG.

  If the web browser 33 is not activated, the controller 41 activates the web browser 33 and reads the web page data 22 designated by the user operation on the input device 15 from the storage device 12 (step S11). Interpretation of the page data 22 is started (step S12).

  The script of the web page data 22 describes a command for transmitting an HTTP request when using the function of the internal device of the image forming apparatus 2. When the web browser 33 is interpreting the web page data 22, the command is detected, an HTTP request corresponding to the command is generated, and transmitted to the image forming apparatus 2 via the communication unit 31 and the communication device 11. (Step S13). As the HTTP request, a GET command is used. At this time, the URL (Uniform Resource Locator) in the HTTP request includes parameters to specify the protocol (HTTP) to be used, the destination web server 73 (that is, the image forming apparatus), the interface 74 to be activated, and the operation of the internal apparatus. It is specified.

  For example, when the URL is http://192.168.0.5/display.cgi?command=display&text=hello&x=10&y=10, the web server 73 of the image forming apparatus 2 whose IP address is 192.168.0.5 is specified. , CGI of display.cgi is designated as the interface 74 to operate the display device 51, and the process of displaying the text “hello” in the coordinate value (10, 10) by the parameter command = display & text = hello & x = 10 & y = 10 Is specified. Note that the image forming apparatus 2 may be specified by a host name.

  When the web server 73 in the image forming apparatus 2 receives the HTTP request, the interface 74 is called. The interface 74 calls the control unit 72 to cause the internal device to execute the operation specified by the HTTP request. The control unit 72 causes the internal device to execute an operation designated by the interface 74.

  When the interface 74 receives the operation result of the internal device from the control unit 72, the interface 74 supplies the operation result to the web server 73. The web server 73 generates a response including the operation result and transmits it to the development device 1. The web browser 33 of the development device 1 receives the response via the communication device 11 and the communication unit 31 (step S14).

  As described above, whenever the web browser 33 executes a command for using the function of the internal device of the image forming apparatus 2 in the web page data 22, an HTTP request is transmitted as in steps S13 and S14, and the HTTP request is transmitted. The image forming apparatus 2 operates in response to the request, and the operation result is obtained as a response. For example, an HTTP request for displaying a character string on the display device 51 is transmitted, and a response indicating whether the display is successful is received. Also, an HTTP request for displaying a predetermined input screen is transmitted, and a response including a value indicating a user operation for the input screen detected by the input device 15 in the image forming apparatus 2 is obtained.

  Thereafter, the web browser 33 continues to process the web page data 22 using the response. Note that portions other than such commands are processed in the development apparatus 1 by the web browser 33.

  Then, when the web page data 22 is executed to the end, the processing of the web page data 22 by the web browser 33 ends (step S15).

  In this way, the development apparatus 1 causes the web browser 33 to interpret the web page data 22 being developed, and uses the function of the image forming apparatus 2 in the HTTP request, so that the web page data 22 (that is, the image forming apparatus). 2 can be executed on a trial basis.

  As described above, according to the above embodiment, (a) the development device 1 interprets the web page data 22 including HTML data and scripts in the web browser 33, and (b) the development device 1 When the browser 33 executes a process for operating the internal device of the image forming apparatus 2 in the script according to the web page data 22, an HTTP request corresponding to the process is transmitted to the web server 73 of the image forming apparatus 2, (C) In the image forming apparatus 2, the web server 73 receives an HTTP request corresponding to the operation of the internal device of the image forming apparatus 2 from the web browser 33, and (d) the image forming apparatus 2 is designated by the HTTP request. (E) in the image forming apparatus 2, the internal device The operation result is supplied to the web server 73. (f) In the image forming apparatus 2, the web server 73 transmits an HTTP request response corresponding to the operation result of the internal apparatus to the web browser 33. (g) The development apparatus 1 The web browser 33 receives a response to the HTTP request from the web server 73 of the image forming apparatus 2.

  Thereby, it is not necessary to introduce the web page data 22 under development into the electronic device, and the operation of the web browser can be confirmed by the web page data by actually operating the internal device of the actual machine. Can realize efficient software development.

  Furthermore, this technique can also be applied to the development of web page data used in an embedded system other than the image forming apparatus 2 (an electronic device incorporating a computer and a program for the purpose of realizing a specific function).

  The above-described embodiments are preferred examples of the present invention, but the present invention is not limited to these, and various modifications and changes can be made without departing from the scope of the present invention. is there.

  For example, in the above embodiment, the image forming apparatus 2 may not include the web browser 75. Even in that case, the user can use the screen displayed on the display device 83 by the web browser 92 of the user terminal device 3 as the remote panel of the image forming apparatus 2.

  In the above embodiment, when the web browser 75 obtains the web page data 65, the web browser 75 may obtain the web page data 65 from the file system of the storage device 54, or send the HTTP data to the web server 73. The web page data 65 may be acquired from the web server 73 by transmitting a request.

  In the above embodiment, the web browser 33 and the web browser 75 may be the same or different. However, it is preferable to use a web browser 33 that conforms to the HTML mode and version that the web browser 75 can interpret.

  The present invention can be applied to, for example, development of web page data used for screen control of an operation panel of a multifunction machine.
