(NFS)
Based on the above description, the information processing system of FIG. 7 including the multi-function peripheral 101 of FIG. 1 will be described. The information processing system shown in FIG. 7 includes a multifunction machine 101 and a server computer 701. The multi-function peripheral 101 and the server computer 701 are connected to each other via a LAN (local area network) 702. Here, the LAN 702 is constructed by Ethernet (registered trademark).

  In the compound machine 101 of FIG. 1, various information processing is executed by various programs such as an application 131 and a platform 132. In the information processing system of FIG. 7, the HDD 233 and the SD memory card 602 (the SD memory set in the SD memory card slot 601) equipped in the multi-function peripheral 101 are used as storage destinations (storage destinations) for information related to the information processing. In addition to the card 602), the HDD 703 and the SD memory card 705 (the SD memory card 705 set in the SD memory card slot 704) installed in the server computer 701 can be used.

  As a technique for realizing this, NFS (Network File System) which is a kind of technique for realizing a distributed file system is used. The file system in the HDD 703 equipped in the server computer 701 is used as the distributed file system of the multifunction machine 101. In the information processing system of FIG. 7, the file system of the server computer 701 corresponding to the distributed file system of the multifunction machine 101 is used as a storage destination (save destination) of information related to information processing by the multifunction machine 101.

  Here, UNIX (registered trademark) is installed as an OS 706 in the HDD 703 provided in the server computer 701, and the server computer 701 can function as a server (NFS server) of an NFS distributed file system. Here, UNIX (registered trademark) is also installed as the OS 136 in the HDD 233 provided in the multi-function peripheral 101, and the multi-function peripheral 101 is used by being connected to the server computer 701 via a network, so that the NFS distributed file system is used. As a client (NFS client). Information processing related to “vfs (virtual file system) operation” and “v-node (virtual node) operation”, which is information processing related to NFS, is executed by these UNIX (registered trademark).

  As a network protocol for the MFP 101 and the server computer 701 to perform NFS-related network communication, IP is used in the network layer (third layer) of the OSI reference model, UDP is used in the transport layer (fourth layer), RPC is used in the layer (fifth layer) and XDR is used in the presentation layer (sixth layer). The application layer (seventh layer) is NFS. TCP may be used in the transport layer (fourth layer), but here, UDP is used in preference to high speed rather than reliability.

  As a technique for realizing the distributed file system, samba may be used instead of NFS. Windows (registered trademark) is installed as the OS 706 in the HDD 703 installed in the server computer 701, and the server computer 701 functions as a server (samba server) of the samba distributed file system. UNIX (registered trademark) is installed as the OS 136 in the HDD 233 provided in the multi-function peripheral 101, and the multi-function apparatus 101 is caused to function as a client (samba client) of the samba distributed file system. By using samba, a UNIX (registered trademark) machine can use a shared folder of a Windows (registered trademark) machine.

  The network protocol for the MFP 101 and the server computer 701 to perform samba-related network communication includes IP in the third layer of the OSI reference model, TCP in the fourth layer, NetBIOS in the fifth layer, and sixth layer. Then, SMB is used. The seventh layer is samba. Note that NetBEUI may be used in the third layer and the fourth layer, and NetBIOS may be used in the fifth layer. Further, IPX may be used in the third layer, and SPX may be used in the fourth and fifth layers. Since the folder sharing function and file sharing function of Windows (registered trademark) are supported by the SMB of the sixth layer, the samba server can be called an SMB server and the samba client can be called an SMB client.

  As described above, as a technique for realizing the distributed file system, “NFS”, “samba”, or other techniques may be used. The case where “NFS” is used will be described.

  Based on FIG. 8, an example of information processing executed in the multifunction machine 101 when the application 131 of the multifunction machine 101 accesses a file stored in the file system of the server computer 701 will be described.

  When the application 131 of the multi-function peripheral 101 accesses a file stored in the file system of the server computer 701, the application 131 makes a mount system call (S801) for the file system of the server computer 701. In response to this, the OS 136 of the multi-function peripheral 101 mounts the file system of the server computer 701 on the multi-function peripheral 101 (S802), and makes the file system of the server computer 701 accessible as a distributed file system of the multi-function peripheral 101.

  Subsequently, the application 131 of the MFP 101 accesses the file by accessing the file system as a distributed file system of the MFP 101.

  The application 131 of the multi-function peripheral 101 makes an open system call (S803) for the file when starting access to the file, and when the access to the file ends, the application 131 A close system call (S806) is performed. By the open system call for the above file, the application 131 of the MFP 101 acquires the file descriptor of the above file, and the OS 136 of the MFP 101 acquires the file handle of the above file.

  When accessing the file, the application 131 of the multifunction machine 101 makes a system call (S804) using the file descriptor for the file. In response to this, the OS 136 of the multi-function peripheral 101 transmits a system call based on the file descriptor for the file as an NFS call based on the file handle for the file to the OS 706 of the server computer 701 (S805). Upon receiving this, the OS 706 of the server computer 701 executes the content of the NFS call for the above file.

  Based on FIG. 9, the file system of the multi-function peripheral 101 will be described. In UNIX (registered trademark), the storage area of the HDD is divided into a plurality of partitions for management. In the UNIX® convention, partitions exist from a to h. a is a root file system “/”, b is a SWAP, c is an entire area, and d to h is a file system such as “/ usr”. FIG. 9 shows an example of a result of displaying information related to the file system of the multifunction peripheral 101 by the df command of OS 136 which is UNIX (registered trademark). FIG. 9 shows that “a” of HDD 233 is mounted at “/”, “e” of HDD 233 is mounted at “/ usr”, and a directory (file) of server computer 701 “host_a”. “/ Dir1”, which is a system), is mounted on “/ host_a / dir1”, which is a directory (mount point) of the multi-function peripheral 101.

  A mounting process for mounting the file system of the server computer 701 on the multifunction machine 101 and an unmounting process for unmounting the file system of the server computer 701 from the multifunction machine 101 will be described in detail.

  In the processing of S801 and S802 of FIG. 8, when the application 131 needs to access the file system, the OS 136 mounts the file system under the system call of the application 131. When the application 131 does not need to access the file system, the OS 136 unmounts the file system under the system call of the application 131. The server computer 701 mounts and unmounts the file system of the server computer 701 according to the necessity of access to the file system of the server computer 701. When it is not necessary to access the file system of the server computer 701, unmounting the file system of the server computer 701 reduces the possibility of the multifunction machine 101 being damaged due to a trouble with the server computer 701.

  Instead of mounting by the mount system call of the application 131, the mount of the file system of the server computer 701 may be executed by using the automount of the OS 136 which is UNIX (registered trademark). .

  Instead of this, the file system of the server computer 701 may be continuously mounted during the operation of the compound machine 101. In this case, a setting file related to the mount processing of the file system of the server computer 701 is prepared in the HDD 233 or the SD memory card 602, and the program starting unit 502 (see FIG. 5) is configured when the MFP 101 is turned on. The OS 136 mounts the file system under the system call of the startup processing program.

  In this way, the information processing system of FIG. 7 can use NFS (Network File System) which is a kind of technology for realizing a distributed file system. Hereinafter, a specific example of the usage mode of NFS in the information processing system of FIG.

(1) First Specific Example FIG. 10 is a diagram for describing a first specific example of an NFS usage mode.

  In the first specific example, the HDD 703 equipped in the server computer 701 or the like is used as a backup destination (restoration source) of the storage information (stored information) in the HDD 233 equipped in the multi-function peripheral 101 or the SD memory card 602.

  Here, the information processing of the first specific example is executed by the MCS 165 (see FIG. 1). That is, the MCS 165 accesses the file system 1001 in the HDD 703 as a distributed file system of the multi-function peripheral 101, and the file 1011 that is storage information (saved information) in the HDD 233 or the SD memory card 602 is stored in the file system 1001. , 1012 (backup files 1021, 1022). Further, the MCS 165 accesses the file system 1001 in the HDD 703 as a distributed file system of the multi-function peripheral 101, and the backup (backup file 1021) of the storage information (saved information) taken in the file system 1001. , 1022) is restored in the HDD 233 or the SD memory card 602 (restore files 1031 and 1032).

  For example, when the “backup button” or “restore button” is touched on the display screen displayed on the touch panel 311 (see FIG. 4) by the application 131, the “backup process” or “restore process” is performed by the MCS 165. You may make it perform. Instead of local operation using the touch panel 311 or the like, remote operation using a terminal device or the like may be used. The “backup processing” may be automatically executed periodically by the MCS 165, for example, the MCS 165 automatically executes once a week. Instead of automatically executing the MCS 165 process periodically, any process that is periodically started may be automatically executed.

  Examples of the files 1011 and 1012 in the HDD 233 and the SD memory card 602 include “images” such as image data scanned by the imaging unit 121 (see FIG. 1) and image data that can be printed by the printing unit 122 (see FIG. 1). A file related to “data”, a file related to “user information” such as authentication information, billing information, resource use restriction information, scanner destination, facsimile destination, etc. Other files may be backed up or restored.

  As an example of the merit of the first specific example, it is possible to prepare for damage to the HDD 233 and the SD memory card 602. In particular, since the UNIX (registered trademark) is adopted here as the OS 136 of the multi-function peripheral 101, it can be said that there is an advantage of adopting the first specific example.

(2) Second Specific Example FIG. 11 is a diagram for describing a second specific example of an NFS usage mode.

  In the second specific example, the HDD 703 provided in the server computer 701 is used as a storage destination (save destination) of the SDK application file 1041 in which the SDK application (refer to the description of FIG. 1) is stored. The SDK application stored in the SDK application file 1041 is reproduced from the HDD 703 provided in the server computer 701, and activated and executed in the multi-function peripheral 101. The SDK application file 1041 is an execution format file of the SDK application.

  Here, the information processing of the second specific example is executed by an activation processing program (refer to the description of FIG. 5) constituting the program activation unit 502. That is, an activation processing program constituting the program activation unit 502 accesses the file system 1001 in the HDD 703 as a distributed file system of the multi-function peripheral 101, and stores an SDK application (SDK application file 1041) stored in the file system 1001. ) Is activated by MEM-P231 (see FIG. 2) or MEM-C232 (see FIG. 2).

(3) Third Specific Example FIG. 12 is a diagram for describing a third specific example of an NFS usage mode.

  In the third specific example, the server computer 701 is used as the storage destination (save destination) of the SDK application file 1042 in which the SDK application (refer to the description of FIG. 1) to which “debugging verification code” is added is stored. The HDD 703 and the like installed in the are used. The SDK application stored in the SDK application file 1042 is reproduced from the HDD 703 provided in the server computer 701, and activated and executed in the multi-function peripheral 101. The SDK application file 1042 is an execution format file of the SDK application.

  Here, the information processing of the third specific example is executed by an activation processing program (refer to the description of FIG. 5) constituting the program activation unit 502. That is, an activation processing program constituting the program activation unit 502 accesses the file system 1001 in the HDD 703 as a distributed file system of the multi-function peripheral 101, and stores an SDK application (SDK application file 1042) stored in the file system 1001. ) Is activated by MEM-P231 (see FIG. 2) or MEM-C232 (see FIG. 2).

  When the above-described SDK application to which the “tag” which is the verification code for debugging is added is activated in the multi-function peripheral 101 to be debugged, the console PC 102 connected to the multi-function apparatus 101 is activated. (See FIG. 1) displays variable values, function arguments, and function return values of the SDK application together with a message. Thereby, the debugging work of the SDK application can be executed efficiently.

  Telnetd, ftpd, emacs, mule, gdb, etc. may be stored in the HDD 703 provided in the server computer 701. This is because the debugging of the above SDK application can be executed more efficiently by making the multifunction machine 101 romboot instead of the netboot, and then remoting the multifunction machine 101 with a telnet or the like from a terminal device or the like. .

(4) Fourth Specific Example FIG. 13 is a diagram for describing a fourth specific example of an NFS usage mode.

  In the fourth specific example, the HDD 703 equipped in the server computer 701 or the like is used as a storage destination (acquisition source) of information stored in the HDD 233 equipped in the multi-function peripheral 101 or the SD memory card 602. Not only backup processing (restoration processing) but also normal storage processing (acquisition processing) is used.

  Here, the information processing of the fourth specific example is executed by the MCS 165 (see FIG. 1). That is, the MCS 165 accesses the file system 1001 in the HDD 703 as a distributed file system of the multi-function peripheral 101, and saves files 1011 and 1012 which are storage information in the HDD 233 and the SD memory card 602 in the file system 1001. (Files 1021, 1022). Further, the MCS 165 accesses the file system 1001 in the HDD 703 as a distributed file system of the multi-function peripheral 101, and stores the storage information (files 1021 and 1022) stored in the file system 1001 in the HDD 233 or SD Obtained in the memory card 602 (files 1031 and 1032).

  Examples of the files 1011 and 1012 in the HDD 233 and the SD memory card 602 include “images” such as image data scanned by the imaging unit 121 (see FIG. 1) and image data that can be printed by the printing unit 122 (see FIG. 1). A file related to “data”, a file related to “user information” such as authentication information, billing information, resource use restriction information, scanner destination, facsimile destination, etc. Other files may be stored or acquired.

  As an example of the merit of the fourth specific example, various devices can share various information. For example, scan data from the first MFP 101 can be used as print data from the second MFP 101, and image data from the MFP 101 can be viewed on a terminal device or the like. For example, the second MFP 101 can acquire the scanner destination and the facsimile destination stored by the first MFP 101, and the user information of the MFP 101 can be edited by a terminal device or the like.

(5) Image Data “Image data” will be described in detail in relation to the first specific example and the fourth specific example.

  A storage format of data stored in the file will be described with reference to FIG.

  In the multi-function peripheral 101, as shown in FIG. 14A, image data (scan data and print data) for image formation processing (scan processing and print processing) is a file in a storage format in which a storage area such as an HDD is continuous. And is stored in the HDD or the like. A file in a storage format for image formation processing as shown in FIG. 14A is referred to as a “RAW file”.

  In the UNIX (registered trademark) file system, as shown in FIG. 14B, various data are stored in a file in a storage format such that the storage area of the HDD or the like is discrete and stored in the HDD or the like. A file in a storage format for a UNIX (registered trademark) file system as shown in FIG. 14B is referred to as an “FS file”.

  In the “backup process” of the first specific example and the “save process” of the fourth specific example, the image forming job (scan job or print job) unit is stored in the HDD 233 or the SD memory card 602 provided in the multi-function peripheral 101. In the file system 1001 in the HDD 703 provided in the server computer 701, the image data stored and stored in the RAW file is stored in the FS file in units of image forming jobs (scan jobs and print jobs). Shall be preserved.

  In the “restoration process” of the first specific example and the “acquisition process” of the fourth specific example, the image forming job (scan job or print job) is stored in the file system 1001 in the HDD 703 provided in the server computer 701. The image data stored and saved in the FS file in units is stored in the HDD 233 or the SD memory card 602 provided in the multi-function peripheral 101 in units of the image forming job (scan job or print job). It is assumed that it is acquired by storing in a RAW file.

  Since the RAW file has an advantage that reading and writing can be speeded up, it can be said that the RAW file is suitable for image forming processing that requires high speed. Since the backup process of the first specific example and the storage process of the fourth specific example have a processing format called a conversion process from a high-speed RAW file to a low-speed FS file, the backup process of the first specific example and the save process of the fourth specific example The concern that the storage process may limit the image forming process is also avoided. The CPU 211 of the multi-function peripheral 101 is used for the image forming process, and the DMA transfer is used for the backup process of the first specific example and the storage process of the fourth specific example, so that the backup process and the fourth specific example of the first specific example are used. The storage process of a specific example can also be executed asynchronously with the image forming process.

  For convenience of image forming processing, image data for image forming processing is stored and stored in a RAW file or FS file for each image forming job. When three pages of image data are scanned in a single scan job, the image data for three pages is stored and stored in one RAW file or FS file, and image data for five pages is stored in one print job. Is printed, image data for five pages is stored and stored in one RAW file or FS file.

  FIG. 19 is a sequence diagram when the backup process of the first specific example and the storage process of the fourth specific example are applied to print processing as a printer.

  The PC instructs the multi-function peripheral 101 to execute print processing (S501), and transfers the print data to the multi-function peripheral 101 (S502).

(6) User information “User information” will be described in detail in relation to the first specific example and the fourth specific example.

  The multi-function peripheral 101 performs authentication processing and usage restriction processing for users who use the multi-function peripheral 101. That is, the user who uses the multi-function peripheral 101 is authenticated by the multi-function apparatus 101. Furthermore, the user who uses the multi-function peripheral 101 “user A can use the copy function, user B cannot use the facsimile function” or “user A can use file A, and user B can use directory B. There is a restriction on the use of resources of the multi-function peripheral 101 that says “impossible”. Authentication processing and usage restriction processing are performed by the CCS 167.

  In the multi-function apparatus 101, authentication information for imposing authentication by the multi-function apparatus 101 for a user who uses the multi-function apparatus 101, and for restricting the use of resources of the multi-function apparatus 101 to a user who uses the multi-function apparatus 101 Usage restriction information is stored (saved). The storage destination (save destination) of the authentication information and use restriction information may be in the HDD 233 or the SD memory card 602 provided in the multi-function peripheral 101. However, in consideration of the use form of the authentication information and use restriction information, the magnetic memory The SD memory card 602, which is an IC memory, is better than the HDD 233, which is. The NVRAM equipped in the multi-function peripheral 101 may be used as a storage destination (save destination) for authentication information and use restriction information. Authentication information and usage restriction information are managed by the UCS 168.

  For authentication registration and use restriction setting of the multi-function peripheral 101, a user who manages the multi-function peripheral 101 registers authentication information of a user who uses the multi-function peripheral 101, sets use restriction information, and restarts the multi-function peripheral 101. It becomes effective by doing. This is the same as UNIX (registered trademark) account registration and mode setting.

  In the “backup process” of the first specific example and the “save process” of the fourth specific example, the use restriction information stored (saved) in the SD memory card 602 (or in the HDD 233) equipped in the multi-function peripheral 101. Are stored in the file system 1001 in the HDD 703 provided in the server computer 701.

  In the “restoration process” in the first specific example and the “acquisition process” in the fourth specific example, the above-described use restriction information stored in the file system 1001 in the HDD 703 equipped in the server computer 701 is used as the MFP 101. The data is acquired in the SD memory card 602 installed in the HDD (or in the HDD 233).

  With the advancement of information processing functions of the multifunction machine 101, the security of the multifunction machine 101 has become an important issue, but the usage restriction information is important information for securing the security of the multifunction machine 101. Therefore, the loss of the usage restriction information should be avoided by all means, so the usage restriction information is backed up by the backup processing of the first embodiment. Furthermore, the use restriction information is stored by the storage process of the fourth embodiment for the purpose of sharing the use restriction information.

  FIG. 20 is a sequence diagram related to the authentication process and the use restriction process.

  First, an authentication registration request is transmitted from the application 131 to the CCS 167 (S601). Next, the CCS 167 executes authentication registration processing of the application 131 (S602). Next, an authentication registration response is transmitted from the CCS 167 to the application 131 (S603). In the authentication registration response, an authentication method such as “login, media, biometrics, coin rack, prepaid card” is notified.

  Next, an authentication screen display request is transmitted from the application 131 to the CCS 167 (S611). Next, when a user inputs authentication information on the authentication screen, an authentication request for the user is transmitted from the CCS 167 to the UCS 168 (S612). Next, the UCS 168 executes authentication processing for the user (S613). Next, the authentication response of the user is transmitted from UCS 168 to CCS 167 (S614). Then, the CCS 167 distributes the user's ticket (S615) as the use restriction process (use restriction release process) of the user. Finally, an authentication screen display cancel request is transmitted from the application 131 to the CCS 167 (S616).

(7) Power Mode The “power mode” will be described in detail with reference to the second specific example and the third specific example.

  The power mode of the multi-function peripheral 101 includes an “ON mode” corresponding to a power-on state and an “OFF mode” corresponding to a power-off state. When using the multifunction machine 101, from the viewpoint of convenience, it is desirable that the multifunction machine 101 is always in the ON mode and is in a standby state for image forming processing. It is not desirable to always set 101 to the ON mode and wait for image forming processing.

  Therefore, in the ON mode, there is a “power saving mode” for saving power consumption during the standby of the image forming process in addition to the normal “standby mode” during the standby of the image forming process. In the power saving mode, the power source of the power consumption portion in the standby state of the image forming process such as the heater power source of the fuser of the printing unit 122, the motor power source of the spindle of the HDD 233, the panel power source of the touch panel 311 is in the power saving state. The power source of the portion with low power consumption during standby for image forming processing, such as the power source of, remains in the standby state. In this way, both the viewpoint of convenience and the viewpoint of power saving are achieved.

  In the standby mode, when a certain time (such as 3 minutes) elapses or a certain time period (such as midnight) arrives, the mode is changed to the power saving mode. When the operation of the multi-function peripheral 101 is executed in the power saving mode, a transition to the standby mode is made. In the power saving mode, when a certain time (such as 3 minutes) elapses or a certain time zone (such as midnight) arrives, the mode changes to the OFF mode. When fax image data, scan data, or print data is received in the OFF mode, a transition is made to the power saving mode. When the power button is turned off, the power mode changes from the ON mode (standby mode or power saving mode) to the OFF mode. When the power button is turned on, the power mode changes from the OFF mode to the ON mode (standby mode).

  FIG. 21 is a sequence diagram relating to a transition process from the standby mode to the power saving mode.

  In the standby mode, when a certain time elapses or a certain time zone is reached (S711), a request for transition to the power saving mode is transmitted from the SCS 169 to the MCS 165 or the application 131 (S712), and the MCS 165 or the application 131 is transmitted. To SCS 169, a response to transition to the power saving mode is transmitted (S713). Subsequently, a notification of transition confirmation to the power saving mode is transmitted from the SCS 169 to the MCS 165 and the application 131 (S714). Subsequently, the MCS 165 transmits a notification of confirmation of transition to the power saving state of the power supply of the HDD 233 to the application 131 (S715).

  When the operation of the multi-function peripheral 101 is executed in the power saving mode (S721), a notification of confirmation of transition to the standby mode is transmitted from the SCS 169 to the MCS 165 and the application 131 (S722). Subsequently, the MCS 165 transmits to the application 131 a notice for confirming the transition to the standby state of the HDD 233 (S723).

  FIG. 22 is a sequence diagram relating to a transition process from the power saving mode to the OFF mode.

  In the power saving mode, when a certain period of time has passed or a certain period of time has been reached (S731), a request for transition to the OFF mode is transmitted from the SCS 169 to the MCS 165 or the application 131 (S732), and from the MCS 165 or the application 131 A transition response to the OFF mode is transmitted to the SCS 169 (S733). Subsequently, the notification of transition confirmation to the OFF mode is transmitted from the SCS 169 to the MCS 165 and the application 131 (S734). Subsequently, the MCS 165 transmits a notification of transition confirmation to the power-off state of the HDD 233 to the application 131 (S735).

  When the fax image data is received in the OFF mode (S741), the fax image data is accumulated from the FCS 162 to the MCS 165 (S742), and a fax image data accumulation notification is transmitted from the MCS 165 to the application 131 (S743). . Next, when a fax image data accumulation notification is transmitted from the application 131 to the SCS 169 (S744), a transition confirmation notification to the power saving mode is transmitted from the SCS 169 to the MCS 165 or the application 131 (S745). Next, the MCS 165 transmits to the application 131 a notification of confirmation of transition to the power saving state of the power supply of the HDD 233 (S746).

  In the power saving mode, since the power source of the HDD 233 is in the power saving state, it is impossible to start the program from the HDD 233, but the power source of the NIC 241 remains in the standby state, so that the program from the NIC 241 is started. The program can be started from the network. The program in the HDD 233 provided in the multi-function peripheral 101 cannot be started, but the program in the HDD 703 (or the SD memory card 705) provided in the server computer 701 can be started. Therefore, in the second specific example and the third specific example, the HDD 703 provided in the server computer 701 is used as the storage destination (save destination) of the SDK application, and the file system 1001 in the HDD 703 provided in the server computer 701 is used. The above-described SDK application stored (saved) is activated in the multi-function peripheral 101.

  In the second specific example, the SDK application can be activated in both the standby mode and the power saving mode. In the third concrete example, even if the standby mode is changed to the power saving mode during the debugging of the SDK application, the debugging of the SDK application is not hindered.

  FIG. 23 is a flowchart relating to the activation process of the SDK application in the HDD 233.

  When the MFP 101 starts the SDK application in the HDD 233 in the MFP 101 (S811), the MFP 101 reproduces the execution part of the SDK application in a VM (virtual memory) (S812). When the SDK application is in the idle state (S813) and the power mode is changed to the power saving mode (S814), the MFP 101 determines that the necessary part of the SDK application is not played back on the VM (S815). The HDD 233 is accessed to reproduce the necessary part of the SDK application to the VM (S816). However, since the HDD 233 is in the power saving state, the HDD 233 cannot be accessed and the necessary part of the SDK application cannot be reproduced to the VM. The SDK application enters a sleep state (S817).

  In order to avoid this, the SDK application itself or daemon may be executed by RAM or ROM, but this causes a problem that RAM and ROM are insufficient.

  FIG. 24 is a flowchart relating to the activation process of the SDK application in the HDD 703.

  When the MFP application in the HDD 703 is activated in the MFP 101 (S821), the MFP 101 reproduces the execution part of the SDK application in a VM (virtual memory) (S822). When the SDK application is in the idle state (S823) and the power supply mode is set to the power saving mode (S824), when the necessary part of the SDK application is not played back on the VM (S825) When the HDD 703 is accessed to reproduce the necessary part of the SDK application to the VM (S826), the NIC 241 is in a standby state, so that the HDD 703 can be accessed and the necessary part of the SDK application can be reproduced to the VM. The SDK application remains in the idle state (S827).
