  In the present embodiment, the printing apparatus 100 will be described as an example of an image processing apparatus. However, a multifunction machine having a scanner function and an image transmission function may be used.

  FIG. 2 is a diagram illustrating an example of a software structure of the printing apparatus 100 according to the present embodiment. Each software shown in FIG. 2 is stored in the ROM 110 or the HDD 107 and executed by the CPU 109.

  The OS (Operation System) layer 201 is generally a real-time OS, but a general-purpose OS such as Linux (registered trademark) may be used. The Java (registered trademark) VM 202 is a virtual machine such as Java (registered trademark), and provides an execution environment of an application. The application framework 203 provides a function for managing the life cycle of the application. The installer service 204 performs an installation process by registering a plurality of applications such as applications A and B described later in the application framework 203.

  An application A 205 and an application B 206 are applications installed by the installer service 204 and provide various functions on the printing apparatus 100. The application A 205 and the application B 206 can be downloaded from the outside of the printing apparatus 100 and installed. At least one of the application A 205 and the application B 206 can exchange with the user via the operation unit 102. Further, at least one of the application A 205 and the application B 206 can receive data from a PC or the like on a network (not shown) via the interface unit 105 and can print using the printer unit 103. The installer service 204 is accessed from an information processing apparatus (not shown) using a browser, and receives a predetermined application file shown in FIG.

  The native function 207 provides a function incorporated in the printing apparatus 100. A function of performing printing by the printer unit 103 based on print data received via the interface unit 105 is an example of the Native function. In this embodiment, it is assumed that the Java (registered trademark) VM 202, the application framework 203, the application A 205, and the application B 206 are stored in the HDD 107. Further, it is assumed that the Native function 207 is stored in the ROM 110.

  FIG. 3 is a diagram illustrating an example of functional blocks of the printing apparatus 100 according to the first embodiment. Each function shown in FIG. 3 is configured as software, and is provided by any one or a part of each software shown in FIG. 2 or a combination of a plurality of software shown in FIG.

  The application management unit 301 is a function included in the installer service 204. An application presence / absence determination unit 302 determines whether there is an application installed via the installer service 204. The application execution determination unit 303 determines whether an application installed via the installer service 204 is being executed, or whether the application is to be executed at a predetermined timing such as when the printing apparatus 100 is activated. Determine. The security identification information determination unit 304 refers to the security identification information 403 shown in FIG. 4 and determines whether or not the application has the security identification information 403.

The degeneration management unit 305 is a function included in the Native function 207. The degeneration management unit 305 performs a process of deactivating the function in which the error has occurred and continuing the operation of the printing apparatus 100 (degeneration operation) depending on the error detected by the error detection unit 306 described later. The error detection unit 306 monitors the status of each unit of the printing apparatus 100 such as the HDD 107 and the interface unit 105, as well as the status of the paper feeding device and paper discharge device of the printer unit 103.
The display unit 307 gives an instruction for displaying a message or the like on the liquid crystal display unit of the operation unit 102. A storage unit 308 writes and reads data to and from the HDD 107 and RAM 111.

  FIG. 4 is a diagram illustrating an example of the structure of an application in the present embodiment. Specifically, the structure of application A 205 and application B 206 in FIG. 2 is shown.

  The application file 401 includes application configuration information 402 and an application entity unit 404. The application configuration information 402 includes security identification information 403. The application management unit 301 included in the installer service 204 extracts the security identification information 403 when installing the application file 401. Then, the storage unit 308 stores the extracted security identification information 403 in the HDD 107 or the RAM 111. The application entity unit 404 is an application entity included in the application file 401. When the application management unit 301 installs the application file 401, the application entity unit 404 is stored in a predetermined area of the HDD 107 by the storage unit 308. The security identification information 403 indicates that the application is related to the security of the printing apparatus 100. By executing the application having the security identification information 403, the security of the printing apparatus 100 is maintained. For example, an application for authenticating the user of the printing apparatus 100, an application for encrypting data stored in the HDD 107 of the printing apparatus 100, an application for realizing secure printing, and the like have the security identification information 403. doing.

  Note that an application that provides an account function that counts the usage status of the printing apparatus 100 may have the security identification information 403. In other words, the security identification information 403 may be used as identification information indicating that the application is used for managing the printing apparatus with respect to the application used for managing the printing apparatus.

  FIG. 5 is a flowchart illustrating an example of processing executed when the printing apparatus 100 according to the first embodiment detects an error in the HDD 107. In the flowcharts of FIGS. 5 and 6, one of the functional blocks illustrated in FIG. 3 will be described as a main body that executes each step, but the functional block illustrated in FIG. 3 is the CPU 109 of the printing apparatus 100. Is realized by executing any of the software shown in FIG. Therefore, this flowchart is realized by the CPU 109 of the printing apparatus 100 executing any of the software shown in FIG.

  In step 501, the error detection unit 306 determines (determines) whether an error in the HDD 107 has been detected. If an error in the HDD 107 cannot be detected, this step is repeated. If an error in the HDD 107 is detected, the process proceeds to step 502.

  In step 502, the display unit 307 displays a message indicating that an error has occurred in the HDD 107 on the liquid crystal display unit of the operation unit 102. In step 503, the application presence / absence determination unit 302 determines whether there is an installed application in the printing apparatus 100. If there is no application installed in the printing apparatus 100, the process proceeds to step 504, and if it exists, the process proceeds to step 505.

  In step 504, the degradation management unit 305 sets “HDD degradation mode”. The “HDD degeneration mode” is a parameter for making a transition to a state in which the HDD 107 is invalidated when the printing apparatus 100 is activated next time. This parameter is stored in a nonvolatile area of the RAM 111 (SRAM / FRAM (registered trademark) or the like). In step 505, the security identification information determination unit 304 determines (determines) whether there is an application having the security identification information 403 among the applications installed in the printing apparatus 100. If it is determined that there is no application having the security identification information 403, the process proceeds to step 506. If it is determined that the application exists, the process proceeds to step 507.

  In step 506, the degradation management unit 305 sets the “HDD degradation mode with warning message” to a non-volatile area of the RAM 111 (SRAM / FRAM (registered trademark) or the like). The “HDD degradation mode with warning message” will be described later.

  In step 507, the application execution determination unit 303 performs the following determination (determination) for an application determined to have the security identification information 403. That is, it is determined (determined) whether (1) an application is being executed or (2) an application to be executed at a predetermined timing such as when the printing apparatus 100 is activated. If it is determined that the application determined as the application having the security identification information 403 is being executed or is an application to be executed at a predetermined timing such as when the printing apparatus 100 is activated, the process proceeds to step 508. On the other hand, if it is determined that the application determined as the application having the security identification information 403 is not being executed or is not an application to be executed at a predetermined timing such as when the printing apparatus 100 is activated, the process proceeds to step 506. If it is determined in step 505 that there are a plurality of applications having the security identification information 403, it is determined in step 507 that at least one of the plurality of applications is an application to be executed when the printing apparatus 100 is started. If yes, go to Step 508. On the other hand, if it is determined in step 507 that none of these applications are to be executed when the printing apparatus 100 is activated, the process proceeds to step 506.

  In step 508, the degeneration management unit 305 sets the “HDD error display mode” to a non-volatile area (SRAM / FRAM (registered trademark) or the like) of the RAM 111. Further, the degradation management unit 305 displays a parameter for displaying an error message indicating that an error has occurred in the HDD 107 on the liquid crystal display unit of the operation unit 102 at the next startup of the printing apparatus 100 in a nonvolatile area (SRAM) of the RAM 111. / FRAM (registered trademark) or the like.

  After executing Steps 504, 506, and 508, this flowchart is terminated. After completing the execution of this flowchart, the printing apparatus 100 stops the printing operation and the reception of the print data, and restarts the printing apparatus 100 in the operation unit 102 (the power is turned off and the power is turned on). Wait with the prompt message displayed. An error code may be displayed as a message. When the user restarts the printing apparatus 100 in such a state, the printing apparatus 100 executes processing described with reference to the flowchart of FIG.

  FIG. 6 is a flowchart illustrating an example of processing executed when the printing apparatus 100 according to the first embodiment is activated. This flowchart is realized by the CPU 109 of the printing apparatus 100 executing any of the software shown in FIG. The flowchart starts execution when the printing apparatus 100 is turned on.

  In step 601, a non-volatile area (SRAM / FRAM (registered trademark) or the like) of the RAM 111 is referred to and it is determined (determined) whether or not “HDD degeneration mode” is set in the startup parameters. . If “HDD degeneration mode” is set, the process proceeds to step 602; otherwise, the process proceeds to step 603.

  In step 602, the operation is performed in the “HDD degeneration mode”. In the “HDD degeneration mode”, the printing apparatus 100 starts up with the HDD 107 disabled. When the HDD 107 is invalidated, the application management unit 301 cannot perform the activation process of the application stored in the HDD 107. Therefore, the printing apparatus 100 operates in a state where the function by the application is not provided, and the printing function (image processing function) provided by the native function 207 stored in the ROM 110 operates.

  In step 603, referring to a non-volatile area of the RAM 111 (SRAM / FRAM (registered trademark), etc.), it is determined whether or not “HDD degeneration mode with warning message” is set in the startup parameters ( decide. If “HDD warning mode with warning message” is set, the process proceeds to step 604, and if not set, the process proceeds to step 606.

  In step 604, the display unit 307 displays a predetermined warning message indicating that there is an unusable application on the liquid crystal display unit of the operation unit 102. In step 605, it is a step, and it is determined whether the warning message displayed in step 604 has been canceled by performing a predetermined operation by the user on the operation unit 102. If it is determined that the warning message has been released, the process proceeds to step 602.

  In step 606, it is determined (determined) whether or not “HDD error display mode” is set in the startup parameters by referring to a non-volatile area of the RAM 111 (SRAM / FRAM (registered trademark) or the like). To do. If the “HDD error display mode” is set, the process proceeds to step 607; otherwise, the process proceeds to step 608. In step 607, the display unit 307 displays an error message on the liquid crystal display unit of the operation unit 102. The error message is a message that urges a service person to request a predetermined recovery process. In the “HDD error display mode”, the printing apparatus 100 is not in an operating state, and the printing function or the like does not operate. In the “HDD error display mode”, the printing apparatus 100 is not executed in the “HDD degeneration mode”. In order to restore the printing apparatus 100 from the “HDD error display mode”, a predetermined restoration process by a service person or the like is required.

  In step 608, since no parameter is set in the non-volatile area (SRAM / FRAM (registered trademark), etc.) of the RAM 111 (no error has occurred in the HDD 107), the operation of the printing apparatus 100 is started normally.

  According to the flowcharts of FIGS. 5 and 6, when it becomes impossible to execute a specific application having the security identification information 403 in steps 507, 508, 606, and 607, the printing apparatus 100 disables the HDD 107 and performs a degeneration operation. To prevent. Accordingly, it is possible to prevent the printing apparatus 100 from operating without executing an application having the security identification information 403, that is, an application necessary for maintaining the security of the printing apparatus 100. Therefore, the security of the printing apparatus 100 can be maintained. Further, in step 604 of FIG. 6, the user of the printing apparatus 100 calls a service person to perform a predetermined restoration process, or if it is determined that there is no influence on the business, the application function is not used and is used as it is. Can continue. As described above, since it is possible to selectively control whether or not to operate in the “HDD degeneration mode”, it is possible to prevent the printing apparatus 100 from malfunctioning and improve user convenience.

  If the application presence / absence determining unit 302 determines in step 503 in the flowchart of FIG. 5 that there is an installed application, the process may proceed to step 508 without performing the determinations in steps 505 and 507. In other words, when an application is installed in the printing apparatus 100 and an error occurs in the HDD 107 while the HDD 107 stores an application file, the “HDD error display mode” is set. In this state, even if the printing apparatus 100 is restarted, the printing apparatus 100 is not ready for operation. In this case, it is possible to shift to the “HDD degradation mode” only when no application is installed in the printing apparatus 100.

  If it is determined in step 505 in the flowchart of FIG. 5 that the application has the security identification information 403, the processing in step 508 may be performed without performing the determination in step 507.

[Second Embodiment]
Hereinafter, a second embodiment for carrying out the present invention will be described with reference to the drawings.

  In the second embodiment, a storage area automatic restoration process and a storage area initialization process in the case where the restoration cannot be performed are added to the first embodiment.

The software structure of the printing apparatus 100 is the same as that shown in FIG. The structure of the application installed in the printing apparatus 100 is the same as that shown in FIG.

  FIG. 7 is a diagram illustrating an example of functional blocks of the printing apparatus 100 according to the second embodiment. Each function shown in FIG. 7 is configured as software, and is provided by any one or a part of each software shown in FIG. 2 or a combination of a plurality of software shown in FIG.

  The application management unit 701 is the same as the application management unit 301 in FIG. The application presence / absence determination unit 702, application execution determination unit 703, and security identification information determination unit 704 included therein are the same as the application presence / absence determination unit 302, application execution determination unit 303, and security identification information determination unit 304 of FIG. It is. Data used when the application presence / absence determination unit 702, the application execution determination unit 703, and the security identification information determination unit 704 perform determination are stored in a nonvolatile area (SRAM / FRAM (registered trademark), etc.) of the RAM 111. .

  An error detection unit 705 monitors the status of each unit of the printing apparatus 100 such as the HDD 107 and the interface unit 105 as well as the status of the paper feeding device and paper discharge device of the printer unit 103.

  The display means 706 is the same as the display means 307 in FIG. The storage unit 707 is the same as the storage unit 308 of FIG. The storage device automatic recovery means 708 has a function of recovering the HDD 107. The storage device initialization unit 709 included in the storage device automatic recovery unit 708 has a function of initializing (formatting) the HDD 107 and restoring the HDD 107 to an initial state.

  FIG. 8 is a flowchart illustrating an example of processing executed when the printing apparatus 100 according to the second embodiment detects an error in the HDD 107. 8 and FIG. 9 will be described so that any one of the functional blocks shown in FIG. 7 is the main body that executes each step. The functional blocks shown in FIG. This is realized by the CPU 109 of 100 executing any of the software shown in FIG. Therefore, this flowchart is realized by the CPU 109 of the printing apparatus 100 executing any of the software shown in FIG.

  In step 801, the error detection unit 705 determines (determines) whether an error in the HDD 107 has been detected. If no error has been detected in the HDD 107, this step is repeated. If an error in the HDD 107 is detected, the process proceeds to step 802. In step 802, the display unit 706 displays a message indicating that an error has occurred in the HDD 107 on the liquid crystal display unit of the operation unit 102. A step 803 sets an “automatic recovery mode” that is a parameter for causing the HDD 107 to be automatically recovered at the next startup of the printing apparatus 100. This parameter is stored in a nonvolatile area of the RAM 111 (SRAM / FRAM (registered trademark) or the like). This flowchart is complete | finished above.

  FIG. 9 is a flowchart illustrating an example of processing executed when the printing apparatus 100 according to the second embodiment is activated. This flowchart is realized by the CPU 109 of the printing apparatus 100 executing any of the software shown in FIG. The flowchart starts execution when the printing apparatus 100 is turned on.

  In step 901, it is determined (determined) whether the “automatic recovery mode” is set with reference to a non-volatile area (SRAM / FRAM (registered trademark)) of the RAM 111. If the “automatic recovery mode” is not set, the process proceeds to step 902, and if it is set, the process proceeds to step 903. In step 902, the printing apparatus 100 performs a normal operation. Here, the printing apparatus 100 executes original functions (printing function and image processing function). Further, the printing apparatus 100 during normal operation also executes a function provided by an application stored in the HDD 107.

  In step 903, the storage device automatic recovery means 708 automatically recovers the HDD 107. Here, the storage device automatic recovery means 708 executes processing for eliminating the error of the HDD 107 and returning to the state before the error occurred. Here, in a known restoration process (eg, CHKDSK, etc.) step 904, it is determined (determined) whether or not the HDD 107 has been restored to the state before the error occurred by the automatic restoration process in step 903. If it is determined that recovery has been achieved, the process proceeds to step 902 and normal operation is performed. On the other hand, if it is determined that the recovery has failed, the process proceeds to step 905. In step 905, the HDD 107 is initialized (formatted).

  In step 906, the application presence / absence determining unit 702 determines (determines) whether there is an installed application in the printing apparatus 100. If it is determined that there is no installed application, the process advances to step 902, and the printing apparatus 100 performs a normal operation. If it is determined that there is an installed application, the process proceeds to step 907. On the other hand, in step 907, the security identification information determination unit 704 determines (determines) whether there is an application having the security identification information 403 among the installed applications. If it is determined that there is no application having the security identification information 403, the process proceeds to step 908. If it is determined that an application having the security identification information 403 is present, the process proceeds to step 910.

  In step 908, the display unit 706 displays a message on the operation unit 102 indicating that the application stored in the HDD 107 has disappeared due to the storage area initialization processing in step 905. In step 909, it is determined whether a predetermined operation by the user for canceling the warning message displayed in step 908 has been performed. If a predetermined operation for canceling is performed, the process proceeds to step 902, and if not, this step is repeated.

  In step 910, the application execution determination unit 703 should execute the application having security identification information (1) whether it is being executed, or (2) at a predetermined timing such as when the printing apparatus 100 is activated. It is determined (determined) whether it is an application. If it is determined that the application having the security identification information is not being executed or is not an application to be executed at a predetermined timing such as when the printing apparatus 100 is activated, the process proceeds to step 908. On the other hand, if it is determined that an application having security identification information is being executed or there is an application to be executed at a predetermined timing such as when the printing apparatus 100 is activated, the process proceeds to step 911. In step 911, an error message is displayed as in the “HDD error display mode” in step 607 of FIG. The error message displayed here is a message that prompts a service person to call for a predetermined recovery process. When this step is executed, a predetermined restoration process is required to restore the printing apparatus 100. Further, the printing apparatus 100 is not in an operating state during the execution of step 911, and the printing function, the image processing function, and the like are not operable.

  As described above, according to the flowchart of FIG. 9, if an application having the security identification information 403 cannot be executed in steps 907, 910, and 911, the printing apparatus 100 is not operated even if the HDD 107 is restored. Accordingly, it is possible to prevent the printing apparatus 100 from operating without executing an application having the security identification information 403, that is, an application necessary for maintaining the security of the printing apparatus 100. Therefore, the security of the printing apparatus 100 can be maintained.

  If the application presence / absence determination unit 302 determines in step 906 in the flowchart of FIG. 9 that there is an installed application, the process may proceed to step 911 without performing the determinations in steps 907 and 910. That is, when an application is installed in the printing apparatus 100, an error occurs in the HDD 107 while the HDD 107 stores an application file, and the HDD 107 is initialized, the “HDD error display mode” is displayed. "Is set. In this state, even if the printing apparatus 100 is restarted, the printing apparatus 100 is not ready for operation.

  If it is determined in step 907 in the flowchart of FIG. 9 that the application has the security identification information 403, the process may proceed to step 911 without executing the process of step 910.
