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

FIG. 1 is a diagram showing a schematic configuration of an image forming apparatus 100 as an information processing apparatus according to an embodiment of the present invention.

In FIG. 1, the image forming apparatus 100 has a control unit 200, an operation unit 220, a printer engine 221 and a scanner engine 222, and a power supply 240, and is connected to a PC 260 and an external server 250 by a LAN 110.

The control unit 200 controls the entire image forming apparatus 100. The operation unit 220 displays various information to the user and accepts the user's operation input. The printer engine 221 prints an image on a recording medium such as paper on the image data output from the control unit 200 according to the printer engine farm 231 stored in a non-volatile storage device (not shown).

The scanner engine 222 reads a document according to the scanner engine farm 232 stored in a non-volatile storage device (not shown), and outputs image data indicating the document image to the control unit 200.

The control unit 200 includes a CPU 210, a chipset 211, a RAM 212, a SRAM 213, a NIC 214, an operation unit interface 215, a printer interface 216, a scanner interface 217, an HDD 218, and a flash memory 219.

The CPU 210 controls the entire image forming apparatus 100 by controlling the control unit 200. The flowchart described later shows a process in which the CPU 210 executes a program expanded from the HDD 218 or the flash memory 219 to the RAM 212.

The RAM 212 is used as a work area of the CPU 210, and stores various data and various programs. The SRAM 213 stores set values, image adjustment values, and the like required by the image forming apparatus 100, and the stored contents are retained even when the power of the image forming apparatus 100 is turned off by the backup power source.

The chip set 211 is a plurality of integrated circuits including an RTC (real-time clock) 270, which is a chip dedicated to time measurement. Since the RTC 270 is supplied with power from a built-in battery (not shown) even if the power is not supplied from the power supply 240, the RTC 270 can operate even when the image forming apparatus 100 is in the sleep state.

As a result, in the state where the power is supplied to the chipset 211, it is possible to wake up from the sleep state. On the other hand, in the shutdown state in which no power is supplied to the chipset 211, the RTC270 cannot operate.

The NIC 214 is an interface for connecting to the LAN 110 and communicating with the PC 260 and the external server 250. In this embodiment, the software can be downloaded from the external server 250, which is an external device, by the NIC 214.

In the following description, software is referred to as firmware or firmware. Further, the update software for updating the farm mounted on the image forming apparatus 100 (hereinafter, referred to as “update”) may be referred to as an update farm.

The operation unit interface 215 is an interface between the operation unit 220 and the control unit 200. The printer interface 216 is an interface between the printer engine 221 and the control unit 200. The scanner interface 217 is an interface between the scanner engine 222 and the control unit 200.

HDD 218 stores various programs and various data. The flash memory 219 stores various data such as set values and various programs used in the image forming apparatus 100. Further, the HDD 218 and the flash memory 219 store various files used for updating the firmware.

FIG. 2 is a diagram for explaining how the firmware mounted on the image forming apparatus 100 is updated in the flash memory 219 and the HDD 218 in FIG. 1.

In FIG. 2, the firmware 310 is an installed firmware. Further, the update program 320 is stored in the flash memory 219.

When the update firmware can be downloaded from the external server 250, the update program 320 follows the firmware download instruction from the CPU 210, and the update program 320 is the update farm storage which is the first storage area provided in the flash memory 219 from the external server 250 via the NIC 214. The update firmware is temporarily stored in the area 321.

Next, the update program 320 expands the update firmware stored in the update farm storage area 321 into the firmware expansion area 330, which is the second storage area provided in the HDD 218, in accordance with the firmware expansion instruction from the CPU 210. This expansion is the process of decrypting the encoded update farm. This coding includes compression or encryption. In the case of compression, decompression is decompression.

Next, according to the update instruction from the CPU 210, the update program 320 is provided with the update farm expanded in the firmware expansion area 330 in the flash memory 219, and stores the update firmware in the firmware copy area 311 which is a third storage area for executing the firmware. To do.

Finally, the update firmware stored in the firmware copy area 311 normally starts replacing the link information for executing the update firmware stored in the firmware copy area 311 instead of the installed firmware according to the instruction of the CPU 210. Occasionally, the firmware 310 update is complete. The replacement of this link information will be described later.

FIG. 3 is a diagram showing each screen displayed on the operation unit 220 in FIG. 1.

FIG. 3A is a diagram showing a menu screen 407, and FIG. 3B is a diagram showing a setting screen 408.

In the menu screen 407 of FIG. 3A, the firmware update key 401 serves as a key for displaying the setting screen 408 of FIG. 3B. Further, the regular update management column 402 is a column indicating whether or not the regular update is valid.

FIG. 6 is a timing chart showing the flow of the update process.

FIG. 6A is a timing chart showing the procedure of the update process in the prior art.

In FIG. 6A, when the download time arrives in the normal operating state in which copying or printing can be executed, the download is performed. After the download is completed, it returns to the normal startup operation state again. After that, when the update time arrives and the update is instructed, the system restarts and the update is activated.

In the conventional update activation state shown in FIG. 6A, the encoded parts are decrypted and expanded, and then the firmware is updated and then restarted again. As described above, in the conventional technology, the downloaded parts are expanded after the update is instructed, so that a long downtime for the update process occurs.

In the following description, a series of processes for decompressing or decrypting the compressed or encrypted parts performed in the above-mentioned conventional technology and then updating the firmware is referred to as a normal update process.

FIG. 6B is a timing chart showing the procedure of the update control process according to the present embodiment.

In FIG. 6B, when the download time arrives during the normal operating state, the download is performed. After the download is completed, the parts stored in the update farm storage area 321 are expanded in the farm expansion area 330, and the normal startup operation state is restored again. As shown in the figure, downloading and unpacking is done as a background process.

After that, when the update time arrives or the update button 406 of the firmware on the update screen 409 is selected by the user, the CPU 210 instructs the update. It restarts according to this update instruction and transitions to the update start state. Then, the parts expanded in the firmware expansion area 330 are stored in the firmware copy area 311.

After that, it is restarted, transitions to the normal startup state, and the link information is replaced to complete the update process. As described above, in the present embodiment, the link information is replaced by the background processing.

As described above, in the present embodiment, since the downloaded parts are immediately deployed, the downtime for the update process can be shortened as compared with the conventional technique.

In the update control process of FIG. 6B, the update is instructed after the expansion is completed, but the update may be instructed during the expansion. In this case, the process during expansion, which will be described later, is performed. First, a flowchart showing the procedure of the process when an update instruction is given after the expansion is completed will be described.

FIG. 7 is a flowchart showing the procedure of the update control process executed by the CPU 210 in FIG.

In FIG. 7, when the download time arrives (YES in step S101), the update program 320 downloads the parts and stores them in the update farm storage area 321 (step S102). Further, at this time, the download screen 410 is displayed on the operation unit 220 (step S103). The step S102 corresponds to the download means.

Next, when the download is completed, the update program 320 immediately expands the parts stored in the update farm storage area 321 to the farm expansion area 330 (step S104). This step S104 corresponds to the deploying means.

Then, when the update program 320 is instructed to update from the CPU 210 (YES in step S105), the update program 320 determines whether or not the parts are being deployed in the farm deployment area (step S106).

If, as a result of the determination in step S106, it is determined that the part is being expanded in the farm expansion area (YES in step S106), the expansion process described later is performed (step S116), and this process is terminated.

On the other hand, as a result of the determination in step S106, if it is determined that the part is not being deployed in the farm expansion area (NO in step S106), the system is restarted to transition to the update activation state (step S111).

Then, the update program 320 stores the parts expanded in the firmware expansion area 330 in the firmware copy area 311 (step S112), restarts the parts, and transitions to the normal operation state (step S113). The step S112 corresponds to the storage means.

Next, the link information described above is replaced (step S114), and this process ends. This step S114 corresponds to the replacement means.

Hereinafter, in the above-mentioned update control process, three types of developing processes, which are processes when an update is instructed by the CPU 210 in the deployed state, will be described.

FIG. 8 is a timing chart showing the procedure of each unfolding process.

FIG. 8A is a timing chart showing the procedure of the developing process A.

In FIG. 8A, when the download time arrives during the normal operating state, the download is performed. After the download is completed, the parts stored in the update firmware storage area 321 are expanded in the firmware expansion area 330, but during the expansion, the update time arrives or the firmware update button 406 on the update screen 409 is pressed. It is assumed that the update is instructed by the CPU 210 by being selected by the user.

When an update is instructed, the deployment is terminated in the middle, the deployed parts are discarded, the system is restarted, and the state transitions to the update startup state. After that, the normal update process will be performed.

If the update time arrives or the update button 406 of the firmware of the update screen 409 is selected by the user in the deployed state, a warning screen indicating that the deployment is stopped is displayed on the operation unit 220. Or the remaining time required for deployment may be displayed on the operation unit 220.

FIG. 8B is a timing chart showing the procedure of the developing process B.

In FIG. 8B, the download time arrives in the normal operating state and the update is instructed to the farm deployment area 330 during deployment, which is the same as in the deploying process A, but in the deploying process B, it is expanded as it is. Continue to deploy all parts.

When all the parts are deployed, the result is the same as when the update was instructed after the deployment was completed. Therefore, in the developing process B, the parts expanded in the firmware expansion area 330 are stored in the firmware copy area 311 by restarting and transitioning to the update activation state in the same manner as when the update is instructed after the expansion is completed. To do.

After that, after transitioning to the normal startup state, the system is restarted, and after the transition to normal startup, the link information is replaced to complete the update process.

FIG. 8C is a timing chart showing the procedure of the developing process C.

In FIG. 8C, the download time arrives in the normal operation state and the expansion is started in the farm expansion area 330, which is the same as the expansion process A. However, in the expansion process C, the expansion state is started and the expansion state is started. To manage. The management of this deployment state will be described.

FIG. 9 is a diagram showing management information 700 that manages the deployed state.

In FIG. 9, the management information 700 is composed of Updatepkgs701, Executing702, and Waiting703.

Updatepkgs701 shows the deployed parts. Executing 702 indicates the part being deployed. Waiting703 indicates a part waiting to be deployed. From this management information, it is possible to determine which part has been deployed, is being deployed, and is waiting to be deployed. This management information is stored in the RAM 212.

Returning to FIG. 8C, if an update is instructed by the CPU 210 during deployment, the deployment will end in the middle, but the parts that are Executing 702 in the management information will continue to be deployed, and the parts waiting to be deployed will be expanded. Reboot without doing and transition to the update startup state.

Then, the parts expanded in the firmware expansion area 330 are stored in the firmware copy area 311. On the other hand, normal update processing is performed for parts waiting to be deployed.

After that, when the system is restarted and the normal state is entered, the link information is replaced only for the parts stored in the firmware copy area 311 and the update process is completed.

Since the expanded parts are used in the developing process C, the downtime is shortened as compared with the developing process A in which the expanded parts are discarded.

Hereinafter, the procedure of each process during development will be described using a flowchart.

FIG. 10A is a flowchart showing the procedure of the developing process A in the update control process of FIG. 7.

In FIG. 10A, if it is determined in step S106 in the update control process of FIG. 7 that the part is being expanded to the farm expansion area (YES in step S106), the expansion is completed and the expanded part is released. Discard (step S201).

Next, the system is restarted to transition to the update activation state (step S202), and a normal update process is performed (step S203). Then, it restarts again to transition to the normal startup state (step S204), and this process ends.

As described above, in the present embodiment, when an update is instructed during the deployment of the update farm, the deployment of the update farm is terminated, the deployed update farm is discarded, and the update farm is placed in the farm deployment area 330. Update the installed farm without deploying.

FIG. 10B is a flowchart showing the procedure of the developing process B in the update control process of FIG. 7.

In FIG. 10B, if it is determined in step S106 in the update control process of FIG. 7 that the part is being deployed in the farm deployment area (YES in step S106), a warning screen indicating that the deployment is to be continued is displayed. It is displayed on the operation unit 220 (step S301).

Next, when all the parts are expanded (YES in step S302), steps S111 to S115 in the update control process of FIG. 7 are performed (step S303), and this process is completed.

As described above, in the present embodiment, if an update is instructed during the deployment of the update farm, the deployment is continued, and after the deployment of the update farm is completed, the firmware copy area 311 is expanded to the firmware deployment area 330. Remember the updated firmware that was created.

FIG. 11 is a flowchart showing the procedure of the developing process C in the update control process of FIG. 7.

As described above, in the developing process C, since the process of managing the deployed state is performed, the process is inserted into the update control process of FIG. 7.

FIG. 11A is a flowchart showing the procedure of the process inserted into the update control process of FIG. 7.

In step S104 of FIG. 7, the parts are deployed in the farm deployment area 330, and at the same time, the deployment state is managed (step S400), and the process proceeds to step S105.

FIG. 11B is a flowchart showing the procedure of the developing process B in the update control process of FIG. 7.

In FIG. 11B, if it is determined in step S106 in the update control process of FIG. 7 that the part is being deployed in the farm deployment area (YES in step S106), the deployment is terminated (step S401). As described above, the expansion is terminated in the middle, but the expansion is continued for the parts that are Executing 702 in the management information.

After that, it restarts and transitions to the update start state (step S402). Then, the parts expanded in the firmware expansion area 330 are stored in the firmware copy area 311 (step S402).

Next, a normal update process is performed on the undeployed parts (step S403). Then, the system is restarted again to transition to the normal startup state (step S304), the link information is replaced (step S405), and this process is terminated.

As described above, in the present embodiment, when an update is instructed during the deployment of the update firmware, the deployment of the update farm is terminated, and the firmware copy area 311 deployed before the deployment is completed is terminated. Remember in.

Then, the link information for executing the update firmware stored in the firmware copy area 311 is replaced, and the installed firmware is updated without expanding the update firmware that was not expanded in the firmware expansion area 330 to the firmware expansion area 330. To do.

As described above, according to the present embodiment, the update farm is downloaded to the update farm storage area 321 by background processing (step S102), and immediately after the download is completed, the update farm is backgrounded in the farm deployment area 330. Expand by processing (step S105).

Then, when the update of the installed software is instructed, the updated firmware expanded in the firmware expansion area 330 is stored in the firmware copy area 311 (step S112), and the firmware copy area is replaced with the installed software. Since the link information for executing the update firmware stored in 311 is replaced by the background process (step S114), the downtime caused by updating the software can be shortened.
