Description

The present invention relates to an image forming apparatus such as a multifunction peripheral , a license management method for an application executed on the image forming apparatus, a control program for executing the license management method on the image forming apparatus, and a computer-readable computer storing the control program The present invention relates to a storage medium .

  Conventionally, an image forming apparatus capable of adding / deleting a function by installing or uninstalling an application is already known. Some of such image forming apparatuses have a function of managing a group of applications operating on the apparatus based on a unique license.

  Examples of information for managing an application included in the license include an application name, a version, a provider, an expiration date, and a usable number of times. These pieces of information are generally held in a storage device in the image forming apparatus and used as needed to manage the operation of the application.

  As a conventional example of a platform for executing an application managed by the above-mentioned license, when executing an application, first, the license information is referred to, and if it is within the expiration date, it is executed as it is. Similarly, even when the number of usable times is managed, the license information is first referred to, and if the usable number of times remains, it is executed as it is.

  However, when the expiration date of the application is expired during the operation of the application, or when the number of usable times is exhausted, the operation of the application is usually restricted or disabled immediately after that. In order to return the application to the normal operation state from this state, the license update procedure is performed, a new license is obtained, the license information in the image forming apparatus is updated based on the license, and the application is updated by the user. Rebooting has become commonplace.

A technology to avoid system interruption due to license expiration is to prompt the user to update the license from a certain period before the license expires by displaying a warning message about the remaining period until the expiration date of the program Has been proposed (see, for example, Patent Document 1).
JP 05-197542 A

  However, in the technique of Patent Document 1 described above, when the user is used to the update operation of the license due to the user getting used to the warning message issued for a certain period before the license expires, the license expires during the operation of the application. There was a risk of occurrence.

  If the license expires during the operation of the application, once the application is terminated, as described above, the user accesses the license server from a personal computer, etc., and performs a license update procedure to obtain a new license. Then, it is necessary to update the license information in the image forming apparatus based on the license, and to restart the application.

  The reason why it is necessary to obtain a new license by performing a license renewal procedure from a personal computer or the like in this way is sufficient to access the external license server directly from the image forming apparatus and perform the license renewal procedure and its acquisition. This is because there is no means.

  The reason that the application needs to be restarted even though the license information has been updated is that the platform only checks the application license information when the application is started. This is because there is no means for the application itself to know that the information has been updated. Therefore, in order to avoid the work of restarting the application, there may be a method in which the application itself operates while periodically checking the license information. However, this method does not always update the license immediately. Therefore, it becomes very inefficient in operation and cannot be adopted.

  From these points, if the license expires while the user is working with the application (for example, if it expires during copying), the license could be updated immediately However, there is still a problem that the application needs to be restarted and the user needs to restart the work. Obviously, the severity of this problem increases in proportion to the amount and importance of the work the user has been doing.

In view of the above-described conventional problems, the present invention enables an image forming apparatus to automatically access a license server and update a license even when a license expires while a user is working using an application. object in the user image forming apparatus can be continued to work without restarting the application without leaving situ methods license management, control program, and to provide a computer readable serial憶媒body And

  Also, the license management service 207 uses the communication function to transmit / receive license information to / from the application (A) 204, notify the license update to the application (A) 204 (notify that the license has been updated), and the like. Making it possible.

  Furthermore, the application management service 208 and the license management service 207 also have a communication function for communicating with each other, and the application management service 208 refers to the license information when managing the operation of the application (A) 204. This communication function is also used when the license management service 207 accesses an external Web server and executes a Web browser to present the Web page.

  The license management service 207 has a function of communicating with the license information database 209 and can perform operations such as creation, addition, correction, and deletion of license information. The license information in the license information database 209 can be updated via the license management service 207 by operating the liquid crystal panel operation display unit 13 or operating from the computer 11 via the network 15.

  Note that the software configuration of the multifunction device 100 is such that a license update operation can be performed from the multifunction device 100 to the application (A) 204 and an appropriate function for notifying that the license has been updated is presented. It is not limited to the software configuration described above.

<Application operation>
Next, the operation of the application according to the present embodiment will be described with reference to FIGS.

  FIG. 3 is a flowchart illustrating a processing procedure of a job executed based on the application (A) 204 by the core unit 10 according to the embodiment. FIG. 4 is a screen diagram illustrating a display screen example when the job according to the present embodiment is temporarily stopped. FIG. 5 is a screen diagram illustrating a screen example when the Web browser 205 accesses the license server 20. It is. FIG. 6 is a screen diagram illustrating an example of a screen when the license update is completed in the Web browser 205. FIG. 7 illustrates a case where the job according to the present embodiment is canceled and the job is resumed. It is a screen figure which shows the example of a screen of time.

  When, for example, the application (A) 204 displayed on the liquid crystal panel operation display unit 13 is executed, the processing shown in the flowchart of FIG. 3 is started.

  First, in step S301, the application (A) 204 receives an execution command. Accordingly, the process proceeds to step S302, and the job of the application (A) 204 is started.

  In step S303, it is determined whether or not the license has been invalidated due to the expiration of the license during the execution of the job, or the number of times of use has expired. Proceeding to step S304, the job of the application (A) 204 ends normally.

  Cases where the license expires during the execution of a job include when the expiration date of the application is reached while the MFP 100 is operating the job while the application is running, There may be a case where the upper limit number of job executions permitted for the application is reached while the multifunction peripheral 100 is operating.

  If the license becomes invalid during execution of the job, the process proceeds to step S305, where the license management service 207 notifies the application (A) 204 that the license has become invalid, and the application (A) 204 Responds to the notification from the license management service 207. Accordingly, the operation of the application (A) or the execution of the job of the multifunction peripheral 100 related to the application (A) is temporarily stopped, and the process proceeds to step S306.

  As another method for suspending the application (A), the license management service 207 notifies the application management service 208 that the license of the application (A) has become invalid, and the application management service 208 notifies the application (A). Alternatively, a pause instruction may be issued.

  In step S306, as shown in the screen example of FIG. 4, the user is notified that the license has expired, a job status screen list 403 indicating jobs that have been canceled due to the license being expired, A pop-up 401 including an instruction to “cancel job or cancel license” is presented, and the process proceeds to step S307. In addition, in the pop-up 401, the user can cancel the job by pressing the cancel button 402. A “license update” button 404 is a button for instructing to activate the Web browser 205 and access the license server 20 in order to perform a license update operation. If “automatic access to the license server” described later is set in step S307, the “license update” button 404 is not displayed.

  In step S307, the license management service 207 checks the license information of the application (A) 204, and determines whether or not the setting for automatically accessing the license server 20 has been made. If automatic access is set, the process advances to step S308 to activate the web browser 205 via the application management service 208, and the process advances to step S309.

  On the other hand, if the setting for automatically accessing the license server is not made in step 307, the process proceeds to step S318, and it is determined whether or not the license update button 404 has been pressed. If the license update button 404 has been pressed, the process proceeds to step S308. If it is determined in step S318 that the license update button has not been pressed, the process advances to step S319 to determine whether the cancel button 402 has been pressed. If the cancel button 402 is pressed in step S319, the process proceeds to step S311. If the cancel button 402 is not pressed, the process returns to step S318 again.

  In step S309, the URL of the license server 20 is acquired from the information described in the license file of the application (A) 204, and the Web browser 205 updates the license on the license server 20 in the next step S310. Access the page.

  When the Web browser 205 accesses a page for updating the license, the Web page 504 of the license server 20 is displayed on the liquid crystal panel operation display unit 13 on a screen as shown in FIG. In other words, the page 504 of the Web browser 501 on the screen displayed on the liquid crystal panel operation display unit 13 is provided with an input area 504a for issuing a license for the application product to be used. By inputting the license access number of application (A) 204, the license of application (A) 204 is issued. An area 502 in FIG. 5 displays a URL (Uniform Resource Locator) of a Web page accessed by the Web browser.

  If the setting for automatically accessing the license server 20 has not been made, the process proceeds to step S311 to wait for the user to manually update the license while the screen remains in the display state of FIG. Here, as another method in which the user manually updates the license, there is a method in which the user manually accesses the license server 20 from the Web browser of the client computer 11 to acquire the license and update the license in the MFP 100. .

  The user 201 recognizes the “information for prompting license update” displayed on the screen of FIG. 4 and performs an operation for updating the license (automatic update using the screen of FIG. 5; When update by pressing the “update” button 404 or manual update on the client computer 11 with the screen of FIG. 4 being performed, the license update is completed as shown in the license update end display page 601 of FIG. Is displayed, the license is downloaded from the license server 20 into the multifunction peripheral 100, and the license information in the license information database 209 is updated through the license management service 207. Then, after updating the license information, the license management service 207 sends a license update notification indicating that the license has been updated to the application (A) 204.

  During the suspension, the application (A) 204 proceeds to step S 311 and is in a standby state until a license update notification is notified from the license management service 207. If the user 201 cancels the job in this state (YES in step S317), the process advances from step S317 to step S304, and the execution of the job ends.

  On the other hand, if the application (A) 204 receives the license update notification in step S311, the process advances to step S312 to determine whether the Web browser 205 is activated. If the web browser 205 is not activated, the process proceeds to step S314 as it is, and if it is activated, the process proceeds to step S313 to terminate the web browser 205 and then proceeds to step S314.

  In step S314, for example, the information necessary for the license to be valid written in the license update notification is confirmed. In the next step S315, the license information can be confirmed. A transition is made to the stop screen (FIG. 4), and the process further proceeds to step S316, where the application management service 208 releases the suspension of job execution. As a result, as shown in the screen example when canceling the suspension of the job (FIG. 7), the remaining processing of the job is resumed, and after all the processing of the job is completed, the process proceeds to step S304 and the job ends.

  According to the present embodiment, since the function of notifying that the license has been updated is provided as a platform, the application can check the license information when receiving the license update notification. Therefore, if the license expires while the user is working with the application (for example, the license expires during copying), the application itself periodically monitors the license information. The restart of the application can be avoided more efficiently than the method. Furthermore, when the license expires while using the application, the license server 20 can be automatically accessed using the web browser 205, so that the license can be easily updated while the user is on the spot.

  As a result, it is possible to continue work without restarting the application, and it is possible to reduce the restart of the application, so that it is possible to reduce the risk in the work of the user and the convenience for the user. Will improve.
