Hereinafter, embodiments of the present invention will be described with reference to the drawings.

I. First Embodiment

FIG. 1 shows the configuration of an image forming apparatus according to a first embodiment of the present invention.

The image forming apparatus 1 in FIG. 1 is, for example, a digital multifunction machine, and has a server function capable of generating a web page in addition to various image forming functions such as a copy function, a scan function, a print function, and a FAX function.

The image forming apparatus 1 of the first embodiment includes a network interface 3 , an operation panel unit 5 , and a main controller 7 along with a server function.

The network interface 3 is connected to a user terminal 9 via a network such as a LAN to transmit and receive data.

The user terminal 9 is an off-device client terminal installed outside the main body of the device. The user terminal 9 includes an information processing device such as a computer. The user terminal 9 transmits a web page generation request (for example, HTTP request) to the image forming apparatus 1 side. The user terminal 9 can also receive a response transmitted from the image forming apparatus 1 and display a web page corresponding to the response (for example, an HTTP response) on the browser. The displayed web page can display device information in addition to operation input to the image forming apparatus 1 or display of operation status.

The displayed device information is the setting state, operating state, etc. of the image forming apparatus 1 . The device information includes information that can be changed by the operation of the image forming apparatus 1 or the user's operation input. As information that can be changed, for example, printing conditions as a setting state, the counted number of sheets as an operating state, paper run-out, and errors of devices with various functions, and the like.

The operation panel unit 5 is an in-device client terminal included in the device main body. The operation panel unit 5 includes a display unit including a display screen 11 , operation keys 13 , and a panel controller 15 .

The display screen 11 includes a touch-panel type liquid crystal display screen and the like, and displays a web page on a browser. The display screen 11 enables operation input to the image forming apparatus 1 , display of operation status, and display of device information through a web page.

The operation keys 13 include a plurality of buttons and the like for accepting operation inputs, and input, for example, execution of functions of the image forming apparatus 1 , and the like.

The panel controller 15 is a computer having an information processing function. The panel controller 15 includes a CPU (Central Processing Unit, central processing unit), a ROM (Read Only Memory, read only memory), and a RAM (Random Access Memory, random access memory).

The CPU is a control element (calculation device) that executes a program to control input or display of the display screen 11 and input of the operation keys 13 . The ROM is a memory that stores programs and the like. The RAM is a memory that temporarily stores the program and various data when the program is executed, and is used as a work area or the like.

The panel controller 15 of the first embodiment executes the client program in response to the activation operation, and operates as the web client 17 . It should be noted that the start-up operation can be performed through the operation keys 13, input on the display screen 11, or the like.

The network client 17 implements client functions. In the first embodiment, an initial generation request is sent to the main controller 7 at startup. The web client 17 receives the response transmitted from the web server 19, and displays a web page on the browser on the display screen 11 in accordance with the response.

Upon receiving the response, the web client 17 sends a next generation request. Thus, a generation request is made while displaying the web page. It should be noted that the generation request during displaying the webpage can be distinguished from the initial generation request through the variable of the header information and the like.

The generation request during the display of the web page may be performed every specific time as polling, for example, or may be performed by input on the display screen 11 or the operation key 13 . In this case, the next generation request is not performed as long as no response to the already performed generation request is received.

The main controller 7 is a computer having an information processing function, and includes a CPU, ROM, and RAM. The main controller 7 executes programs in the CPU, and controls the system of the image forming apparatus 1 and the like.

In addition, the main controller 7 of the first embodiment operates as a web server 19, an event handler 21, and a monitoring unit 23 by executing a server program including a display program. The event handler 21 serves as an event detection unit. The unit 23 functions as a request waiting unit and a waiting release unit.

The web server 19 implements a server function, and generates a web page in response to a generation request from the user terminal 9 or the operation panel unit 5 . The web page includes device information at the time of receiving the generation request, and is described in, for example, HTML (Hypertext Markup Language, Hypertext Markup Language). The web server 19 transmits the generated web page as a response to the user terminal 9 or the operation panel unit 5 that is the source of the generation request.

The event handler 21 implements an event detection function. That is, the event processor 21 notifies the monitoring unit 23 of the occurrence of a change event of device information that can be changed, when it detects the occurrence. For example, the monitoring unit 23 is notified of occurrences of change events such as changes in printing conditions, counted sheets of paper, paper exhaustion, and errors in devices with various functions.

The monitoring unit 23 realizes a request waiting function and a waiting release function. That is, when the monitoring unit 23 receives a creation request while displaying a web page from the user terminal 9 or the operation panel unit 5 , it waits for the received creation request. In the first embodiment, the creation request from the operation panel unit 5 is waited instead of the creation request from the user terminal 9 . However, it may also be configured to wait for a generation request from the user terminal 9 .

After waiting for the request to be generated, the monitoring unit 23 monitors a change event of the device information. When a change event occurs, that is, when a notification is received from the event handler 21, the monitoring unit 23 cancels the wait for the generation request. Thereby, the monitoring unit 23 causes the web server 19 to generate a web page based on the changed device information, and transmits the generated device information as a response.

FIG. 2 shows a flowchart representing display processing performed by the image forming apparatus of FIG. 1 . FIG. 3 is a sequence diagram of display processing performed by the image forming apparatus of FIG. 1 .

In the first embodiment, display processing for displaying a web page is performed by the operation panel section 5 of the image forming apparatus 1 . This display processing is started by performing a start-up operation of the operation panel unit 5 .

First, in step S1 in FIG. 2 (1 "read initial HTML" in FIG. 3 ), the panel controller 15 of the operation panel unit 5 sends an initial request for creating a web page to the main controller 7 via the web client 17 . The process goes to step S2.

In step S2 (1.1 "receiving initial HTML" in FIG. 3 ), the main controller 7 generates a web page including device information through the web server 19 according to the initial generation request. The web server 19 returns the generated web page to the panel controller 15 of the operation panel unit 5 as a response. The process goes to step S3.

In step S3 (2 “Browser display” in FIG. 3 ), panel controller 15 of operation panel unit 5 displays a web page corresponding to the received response on the browser on display screen 11 via web client 17 . The process proceeds to step S4.

In step S4 (3 and 6 "reading HTML" in Fig. 3), the panel controller 15 of the operation panel section 5 sends the next generation request to the main control panel through the web client 17 according to the reception of the response in step S3. device7. The process proceeds to step S5.

In step S5, the main controller 7 waits for the generation request received by the monitoring unit 23, and proceeds to step S6.

In step S6, the occurrence of the change event of the device information is confirmed (3.1 and 6.1 "confirmation event" of FIG. 3). Specifically, the monitoring unit 23 determines the presence or absence of a notification from the event handler 21 .

If there is a notification from the event handler 21 (yes: 4 "event occurrence" in FIG. 3 ), then go to step S7. If there is no notification from the event handler 21, the process of step S6 is repeated (6.1 "event confirmation" in FIG. 3 ).

In step S7 , the monitoring unit 23 cancels the waiting for the generation request (3.2 "waiting cancelled" in FIG. 3 ), and proceeds to step S8.

In step S8 (3.3 "Receive HTML" in FIG. 3 ), the main controller 7 generates a web page including device information after the change event occurs (updated) according to the waiting generation request through the web server 19 . Then, the generated web page response is sent to the panel controller 15 of the operation panel unit 5, and the process proceeds to step S9.

In step S9 (5 “browser display” in FIG. 3 ), the panel controller 15 of the operation panel unit 5 displays the web page corresponding to the received updated response on the browser display screen 11 through the web client 17 . device.

In this manner, after a web page is displayed on the operation panel unit 5 , when a device information change event occurs, the web page can be quickly and reliably updated according to the waiting generation request.

The image forming apparatus 1 of the first embodiment includes: a web server 19 that generates a web page including changeable device information displayed on the operation panel portion 5 in response to a generation request from the operation panel portion 5; a request waiting portion (monitoring portion 23 ), if it receives a generation request from the operation panel portion 5 currently displaying a web page, it waits for the generation request; the event handler 21 detects the occurrence of a change event of the device information; the waiting release portion (monitoring portion 23) , when a change event occurs, the wait for the generation request is released, and the web server 19 is caused to generate a web page based on the changed device information.

Therefore, after a web page is displayed on the operation panel unit 5 , it is possible to quickly and reliably update the web page based on the pending generation request according to the occurrence of a device information change event.

In this way, by adopting a Push-type approach (Approach), real-time performance can be improved without increasing the system load.

In addition, in the first embodiment, by making the operation panel unit 5 display on a web base, it is possible to perform expression with a higher degree of freedom. Furthermore, since general-purpose technology can be applied, customization of the display of the operation panel unit 5 becomes easy, and thus the development cost of the operation panel unit 5 can be reduced.

In addition, a unified interface can be provided between a remote device such as the user terminal 9 and the operation panel unit 5 of the image forming apparatus 1, thereby improving usability.

In the first embodiment, when the operation panel unit 5 has received the response from the web server 19, the next generation request is made as a generation request during displaying the web page.

Therefore, in the first embodiment, it is possible to reduce the load on the system by not performing a generation request while displaying a plurality of web pages. At the same time, it is possible to quickly and reliably wait for a generation request, and further improve real-time performance.

In the first embodiment, as client terminals, there are an operation panel unit 5 provided in the device main body together with a web server 19, and a user terminal 9 provided outside the device main body. The monitoring unit 23 does not wait for a creation request from the user terminal 9 , but waits for a creation request from the operation panel unit 5 .

Therefore, in the first embodiment, an increase in system load can be suppressed by limiting the Push mechanism to only the generation request from the operation panel unit 5 . If the wait for generating requests (Push type mechanism) is applied to all client terminals, the event waiting threads will be randomly arranged in the system, which may increase the system load. That is, in the first embodiment, such inconvenience can be suppressed.

FIG. 5 shows a flowchart of display processing performed by the image forming apparatus of FIG. 4 . FIG. 6 shows a sequence diagram of display processing performed by the image forming apparatus of FIG. 4 .

In the second embodiment, display processing for displaying a web page is performed by the operation panel unit 105 of the image forming apparatus 1 . This display process is started by an activation operation of the operation panel unit 105 or a request to jump to another web page (11 "System Start" in FIG. 6 and "Screen Jump Request" in 6 in FIG. 6 ).

First, in step S11 of FIG. 5 (12.1 "Read initial HTML" in FIG. 6 ), panel controller 115 of operation panel unit 105 sends a web page generation request to main controller 107 via generation request unit 119 . The process proceeds to step S12.

In step S12 (12.2 "Receive initial HTML" in FIG. 6 ), the main controller 107 generates a web page including changeable device information according to the generation request through the server function unit 129 . The server function unit 129 returns the generated web page to the web client 117 as a response. The process proceeds to step S13.

In step S13 (13 "Browser Display & Cache Display Data" in FIG. 6 ), the web client 117 displays the web page corresponding to the received response on the browser on the display screen 111 through its screen display unit 121 . At this time, the storage unit 123 of the web client 117 stores the configuration information of the web page in a cache memory or RAM in the CPU of the panel controller 115 based on the received response. The process proceeds to step S14.

In step S14 , the change information request unit 125 of the web client 117 determines whether or not there is a request to jump from the currently displayed web page to another web page. Specifically, an operation input of a jump request via the operation panel unit 105 is judged.

If there is a jump request, the display process ends (Yes: 16 "Screen Jump Request" in FIG. 6 ). Then, another display process is started, and the displayed web page is updated. In another display process, steps S11 to S13 are performed in the same manner as above (17.1 "Read Next HTML", 17.2 "Receive Next HTML", and 18 "Delete Configuration Information & Update Display" in FIG. 6 ). Then, in S13 , the panel controller 115 discards the configuration information of the stored web page (18 "Delete configuration information & update display" in FIG. 6 ). On the other hand, if there is no jump request, go to step S15 (No).

In step S15 (14.1 “Output request for change information” in FIG. 6 ), the change information request unit 125 sends a change information output request to the web server 127 in accordance with a custom protocol regarding the changeable device information in the web page. Thereby, it transfers to step S16.

In step S16 , the change information confirming unit 131 of the web server 127 judges the presence or absence of change information of the device information upon receipt of the change information output request (4.2 "Confirmation of change information" in FIG. 6 ). That is, the change information confirming unit 131 determines whether or not the device information has been changed between the time of receiving the generation request in step S12 and the time of receiving the output request. Specifically, the change information confirming unit 131 targets individual entities (FIG. 6 Entity) to determine whether the device information has been changed. For example, with regard to the sheet counter, it is judged whether or not the number of counted sheets has been changed.

If the device information is changed, go to step S17 (Yes). If the device information has not been changed, return to step S14 to repeat the process (No).

In step S17 (14.3 "receive change information" in FIG. 6 ), the change information output unit 133 of the web server 127 outputs the change information confirmed in step S16 as a command response corresponding to the data specified by the custom protocol. Thus, step S17 is completed, and the process goes to step S18.

In step S18 (15 "update configuration information & redisplay" in FIG. 6 ), storage unit 123 of web client 117 rewrites the stored web configuration information based on the change information received from web server 127 . Thus, the configuration information is updated. Furthermore, the web page is updated by reflecting the change information to the configuration information. The screen display unit 121 of the web client 117 displays the updated web page on the screen based on the changed configuration information.

When step S18 is completed, return to step S14. After returning to step S14, as long as there is no jump request to the currently displayed web page, the processing of steps S15 to S18 is repeated.

The web client 117 of the second embodiment includes: a generation request unit 119 that outputs a web page generation request so that the web server 127 generates a web page including device information that can be changed; a storage unit 123 that stores the information received from the web server 127; The configuration information of the web page; the change information request unit 125, as long as there is no jump request from the displayed web page to other web pages, it outputs an output request for changing the change information of the device information, so that the network server 127 outputs the change information. Information: The screen display unit 121 displays a received web page, and when receiving change information from the web server 127, displays an updated web page based on configuration information reflecting the change information.

Therefore, the web client 117 of the second embodiment transmits the change information to the web server 127 as long as there is no request to jump from the displayed web page to another web page, so that the system load can be suppressed even if the polling interval is shortened.

Therefore, real-time performance can be improved without increasing system load when displaying device information on a web page.

Furthermore, by reflecting the update information received from the web server 127 on the configuration information of the stored web page, it is possible to easily and reliably update the web page.

In addition, in the network client 117 of the second embodiment, an output request for change information can be output through a custom protocol such as communication between sockets, so that the network server 127 can output the change information.

Therefore, processing such as requesting and receiving change information can be quickly performed, and real-time performance can be improved without increasing the load on the system.

In addition, it is only necessary to limit the command communication to only the changed part of the device information, so the communication performance can be improved.

An image forming apparatus 101 according to the second embodiment includes a web client 117 and a web server 127 . The web client 117 can constitute the operation panel unit 105 together with the display screen 111 displaying web pages.

Therefore, even when the web page from the own web server 127 is displayed on the own operation panel unit 105, the real-time performance can be improved without increasing the system load.

In the second embodiment, by making the display on the operation panel unit 105 based on the network, it is possible to perform expression with a higher degree of freedom. Furthermore, since general-purpose technology can be applied, customization of the display of the operation panel unit 5 becomes easy, and thus the development cost of the operation panel unit 5 can also be reduced.

In addition, a unified interface can be provided between a remote device such as the user terminal 109 and the operation panel unit 5 of the image forming apparatus 101 , and usability can also be improved.

In the second embodiment, the web server 127 of the image forming apparatus 101 includes: a server function unit 129 that generates an output web page according to a web page generation request; and a change information confirming unit 131 that confirms device information according to the change information output request. The presence or absence of the change information; the change information output unit 133, which outputs the change information confirmed by the change information confirming unit 131.

Therefore, when image forming apparatus 101 of the second embodiment receives an output request for change information, it processes it without going through server function unit 129 , thereby reducing system load and improving real-time performance.
