  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated in detail, referring drawings. The same constituent elements are denoted by the same reference numerals, and the description thereof is omitted. First, constituent blocks necessary for the present embodiment will be described, and then details of the processing will be described.

[First embodiment]
FIG. 1 is a block diagram illustrating a configuration of the information processing apparatus 100.

  In FIG. 1, the control unit 200 is configured to control the entire information processing apparatus 100. The control unit 200 includes the following components for controlling the information processing apparatus 100.

  The CPU 210 reads the program for the control unit 200 (first program) stored in the flash ROM 211 into the RAM 212 and executes it.

  A hard disk drive (HDD) 213 stores print data received from the PC 226 via the network I / F 218. Note that the program executed by the CPU 210 includes a print application program to be described later. The print application program converts the print data stored in the HDD 213 into image data that can be printed by the printer unit 220. The HDD 213 also stores image data that can be printed by the printer unit 220. The program executed by the CPU 210 includes a scan application program described later. Then, by this scanning application program, image data is read by the scanner unit 221 and the read image data is transferred to the HDD 213. The HDD 213 stores the read image data. The SRAM 227 stores information indicating which of a main partition and a sub partition, which will be described later, should be activated when the information processing apparatus 100 is activated. In addition, when information indicating that the main partition should be started is stored, information indicating whether to start in the normal start mode described later or the update mode for updating the subpartition program is further stored. The

  The operation unit I / F 214 is an I / F for transmitting an instruction input by the operator of the information processing apparatus 100 to the CPU 210 via the operation unit 219. Further, the operation unit I / F 214 receives from the CPU 210 for switching the contents displayed on the operation unit 219 and transmits the received content to the operation unit 219.

  The printer I / F 215 is an interface for connecting the control unit 200 to the printer unit 220 and the finisher unit 222. Here, the printer unit 220 performs printing on a sheet based on image data transferred from the HDD 213 via the printer I / F 215. The printer unit 220 (printing unit) includes a CPU 220a and a flash ROM 220b. The CPU 220a executes the program (second program) stored in the flash ROM 220b, thereby causing the printer unit 220 to execute various operations associated with the print processing.

  The finisher unit 222 performs various finishing processes on the sheet printed by the printer unit 220. The finishing process is, for example, a stapling process for a sheet, a punching process (punching process) for the sheet, and the like. The finisher unit 222 includes a CPU 222a and a Flash ROM 222b. The CPU 222a executes the program (second program) stored in the flash ROM 222b, thereby causing the finisher unit 222 to execute various operations associated with the finishing process.

  The scanner I / F 216 is an interface for connecting the control unit 200 and the scanner unit 221. Here, the scanner unit 220 (input means for inputting image data) reads an image on a document as image data using a line sensor constituted by a CCD (Charge Coupled Device) or the like. The scanner unit 220 transfers the read image data to the HDD 213 via the scanner I / F 216. The image data transferred to and stored in the HDD 213 can be printed by the printing unit 220 described above, and the image data read by the scanner unit 221 is printed by the printing unit 220, so that copying (copying) processing can be performed. It becomes possible. The scanner unit 221 includes a CPU 221a and a FlashROM 221b. The CPU 221a causes the scanner unit 221 to execute various operations associated with the scanning process by executing a program (second program) stored in the FlashROM 221b.

  The USB-Host I / F 217 is an interface for connecting the control unit 200 and the USB-FAX unit 223. Here, the USB-FAX unit 223 performs FAX transmission via the FAX line 115 based on image data transferred from the HDD 213 via the USB-Host I / F 213. The USB-FAX unit 223 generates image data based on data received via the FAX line 115 and transfers the image data to the HDD 213 via the USB-Host I / F 213. Note that the image data stored in the HDD 213 is printed on a sheet by the printer unit 220 as described above. The USB-FAX unit 223 includes a CPU 223a and a FlashROM 223b. The CPU 223a causes the USB-FAX unit 223 to execute various operations associated with FAX communication processing by executing a program (second program) stored in the FlashROM 223b.

  The network I / F 218 connects the control unit 200 to the LAN 110 and communicates with the PC 226 and the server device 225 on the LAN 110. The server device 225 stores update information for updating various programs (to be executed by the information processing device 100), which will be described later, in response to a request from the information processing device 100. Update information is transmitted to the information processing apparatus 100.

  Next, the configuration of a program executed by the CPU 210 (first control means) of the control unit 200 will be described with reference to FIG.

  2 is stored in the flash ROM 211 of FIG.

  The program stored in the flash ROM 211 is stored in two partitions on the flash ROM 211. One is a main partition 401 and the other is a sub-partition 402. When causing the information processing apparatus 100 to perform a normal operation, the CPU 210 executes an operating system program (hereinafter referred to as OS) stored in the main partition. On the other hand, when updating a program (a main module 410 described later) for causing the information processing apparatus 100 to perform a normal operation, the CPU 210 executes the OS stored in the subpartition.

  The main partition 401 includes three program modules: an OS 411, a main module 410, and an update module 420. The OS 411 is an OS for controlling the information processing apparatus 100, and is a driver program for controlling the operation of each unit of the information processing apparatus 100 including the printer unit 220, the scanner unit 221, the finisher unit 222, and the USB-FAX unit 223. Is included.

  The subpartition 402 includes two program modules, an OS 431 and an update module 430. The OS 431 is an OS for controlling the information processing apparatus 100, and is a driver program for controlling the operation of each part of the information processing apparatus 100 including the printer unit 220, the scanner unit 221, the finisher unit 222, and the USB-FAX unit 223. Is included. The OS 431 is the same as the OS 411 described above.

  The reason why two modules other than the OS 411 are stored in the main partition 401 is to selectively execute each module according to the activation mode of the information processing apparatus 100. Specifically, in the normal startup mode for causing the information processing apparatus 100 to perform a normal operation, the CPU 210 executes the OS 411 and executes each program included in the main module 410. In this normal activation mode, the CPU 210 does not execute the program included in the update module 420. In the update mode in which the program stored in the subpartition 402 is updated, the CPU 210 executes the OS 411 and the program included in the update module 420. In this update mode, the CPU 210 does not execute each program included in the main module 410.

  Here, each program module included in the main module 410 of the main partition 401 will be described. Each program module is an application program executed by the OS 411 after the OS 411 is activated.

  The operation unit application program 412 included in the main module 410 transmits an instruction input by the operator of the information processing apparatus 100 to the CPU 210 via the operation unit 219, and executes processing according to the transmitted instruction. It is a program. The scan application program 413 is a program for controlling the scan processing by the scanner unit 221 described above. The print application program 414 is a program for controlling print processing by the printer unit 220 described above. The network application program 415 is a program for communicating with the PC 226 and the server device 225 on the LAN 110. The update preparation program 416 is a program for the information processing apparatus 100 operating in the normal activation mode to execute a preparation operation for executing a program update.

  The sub partition update 421 included in the update module 420 is a program for updating the update module 430 and the OS 431 included in the sub partition 402.

  Next, each program module included in the update module 430 of the sub partition 402 will be described. Each program module is an application program executed by the OS 411 after the OS 411 is activated.

  The main partition update program 432 is a program (first update program) for updating the main module 410, the update module 420, and the OS 411 included in the main partition 401. The processing unit update program 433 (second update program) is a program for updating a program for executing print processing included in the FlashROM 220b and a program for executing scan processing included in the FlashROM 221b. The processing unit update program 433 is a program for executing a finishing process included in the FlashROM 222b. The processing unit update program 433 is also a program for updating a program for executing FAX communication processing included in the FlashROM 223b.

  Next, the program update process in the first embodiment will be described with reference to FIGS.

  FIG. 6 is a flowchart illustrating processing that is started in response to the information processing apparatus 100 being switched from the off state to the on state.

  FIG. 3 is a flowchart showing processing when the program of the main partition 401 is executed in the normal activation mode.

  FIG. 4 is a flowchart showing processing when the program of the sub partition 402 is executed.

  FIG. 5 is a flowchart showing processing when the program of the main partition 401 is executed in the update mode.

  3 to 5 is performed by the CPU 210 of the control unit 200 executing a program stored in the flash ROM 211.

  First, the process for determining the activation mode of the information processing apparatus 100 and activating in the determined activation mode will be described with reference to FIG.

  6 is started in response to the information processing apparatus 100 being switched from the off state to the on state. The off state refers to a state in which power from the power source is not supplied to each unit of the information processing apparatus 100. The case where the switch is switched from the off state to the on state refers to a case where a main switch (not shown) is turned on or a case where the information processing apparatus 100 is restarted as described later.

  6 is a process performed by reading the boot program stored in the flash ROM 211 of the control unit 200 into the RAM 212 and executing it by the CPU 210.

  In step S601 in FIG. 6, the CPU 210 determines whether or not information indicating that the SRAM 227 should be activated by the sub-partition is stored. If CPU 210 determines YES, the process proceeds to step S603, and if NO, the process proceeds to step S602.

  In step S603, the CPU 210 activates the subpartition program to update the main partition program. The processing in step S603 will be described with reference to FIG.

  In step S602, the CPU 210 determines whether the SRAM 227 stores information indicating that it should be started by the main partition and the update mode is designated. If CPU 210 determines YES, the process proceeds to step S604, and if NO, the process proceeds to step S605. If NO is determined in step S602, the SRAM 227 stores information indicating that it should be started by the main partition, and further stores information indicating that it should be stored in the normal startup mode. Has been.

  In step S604, the CPU 210 executes the update process of the subpartition program by starting the program of the main partition in the update mode. The processing in step S604 will be described with reference to FIG.

  In step S605, the CPU 210 activates the main partition program in the normal activation mode. The process in step S605 will be described with reference to FIG.

  In addition, after performing the processing of steps S603, S604, and S605, in order to automatically restart the information processing apparatus 100, the power source of the information processing apparatus 100 is switched to the off state and then switched to the on state. In this way, the process of FIG. 6 is started again, and the information processing apparatus 100 is activated in an appropriate mode according to the information stored in the SRAM 227.

  Information stored in the SRAM 227 is shown in the description of the flowchart of FIG. 3 to be described later.

  Next, the processing when the program of the main partition 401 is executed in the normal startup mode will be described using FIG. Each process in FIG. 3 corresponds to step S605 in FIG. 6 described above.

  In step S301, the CPU 210 activates the information processing apparatus 100 in the normal activation mode. Specifically, the CPU 210 activates the OS 411, and each program module included in the main module 410 is executed by the activated OS 411.

  In step S302, the CPU 210 determines whether or not an instruction to execute an update process for updating the program of the information processing apparatus 100 has been issued. If it is determined that the update process has been performed, the process proceeds to step S303. Here, the execution instruction of the update process refers to an instruction made by the operator of the information processing apparatus 100 via the operation unit 219, for example. Alternatively, a schedule may be set in advance so that the program is periodically updated every certain period (for example, two weeks), and an execution instruction for the update process may be automatically issued periodically.

  In step S303, the CPU 210 executes the update preparation program 416 via the OS 411 to identify a program that is an update candidate among the programs stored in the FlashROM 211 and the FlashROMs 220b to 223b. For example, a display screen for designating each program is displayed on the operation unit 219, and a program instructed by the operator via the operation unit 219 is specified as an update candidate. Note that all programs that can be update candidates may be specified as update candidates without being based on instructions from the operator.

  In step S304, the CPU 210 executes the update preparation program 416, and transmits an acquisition request for model ID information and version information for specifying the information processing apparatus 100 to the server apparatus. Then, the information processing apparatus 100 acquires version information managed by the server apparatus 225. Here, the version information is information indicating the version of each program module included in the main module 410 described above. When the server apparatus 225 receives a model ID and version information acquisition request from the information processing apparatus 100, the server apparatus 225 identifies version information corresponding to the model ID and transmits the identified version information to the information processing apparatus 100.

  In step S <b> 305, the CPU 210 executes the update preparation program 416 and acquires version information of the information processing apparatus 100. Here, the version information of the information processing apparatus 100 refers to information indicating the version of each program stored in the FlashROM 211 and the FlashROMs 220b to 223b.

  In step S306, the CPU 210 executes the update preparation program 416 and identifies a program to be updated. Specifically, a program whose version information is different between the server device 225 and the information processing device 100 is specified from among the update candidate programs specified in step S303. As a result, it can be seen that a newer version program than the information processing apparatus 100 can be downloaded from the server apparatus 225.

  In step S307, the CPU 210 acquires the update target program (update information) identified in step S305 from the server device 225. Specifically, the information processing apparatus 100 transmits program specifying information indicating the update target program specified in step S306 to the server apparatus 225. When the server device 225 receives the program specifying information from the information processing device 100, the server device 225 transmits a program corresponding to the program specifying information to the information processing device 100. Note that the update target program received from the server device 225 is stored in the main partition 401 of the Flash ROM 211.

  In step S308, the CPU 210 determines whether or not the update target program specified in step S306 includes the program of the main partition 401. If included, the process proceeds to step S309. The process proceeds to step S310.

  In step S309, the CPU 210 causes the SRAM 227 to store information indicating that it should be started by the main partition and information indicating that it should be stored in the update mode.

  In step S310, the CPU 210 determines whether the program to be updated specified in step S306 includes the program of the processing unit (each program stored in the Flash ROMs 220b to 223b). If it is determined that it is included, the process proceeds to step S309. If it is determined that it is not included, the process proceeds to step S311.

  In step S311, the CPU 210 determines whether the update target program specified in step S306 includes the program of the subpartition 402. If included, the process proceeds to step S312. End the process.

  In step S312, the CPU 210 causes the SRAM 227 to store information indicating that it should be activated by the subpartition.

  Next, processing when the program of the sub partition 402 is executed (processing for updating the program of the information processing apparatus 100) will be described with reference to FIG. Each process in FIG. 4 corresponds to step S603 in FIG. 6 described above.

  In step S401, the CPU 210 confirms that the flag indicating that the subpartition program is to be activated is stored in the SRAM 227, and activates the subpartition program.

  In step S <b> 402, the CPU 210 executes a save process for saving a program (save information) stored in the main partition 401. Specifically, all the programs stored in the main partition 401 are copied to the sub partition 402 and saved. If there is not enough free space in the subpartition 402, it may be saved in the HDD 213. The reason for executing such a saving process is to enable restoration to the state before the update when the update process of the program of the main partition 401 is not completed.

  In step S <b> 403, the CPU 210 executes update processing of each program in the main partition 401 by executing the main partition update program 432.

  In step S404, the CPU 210 determines whether or not the update process of each program in the main partition 401 has been successful. If it is determined that the update has been successful, the process proceeds to step S405. On the other hand, if it is determined that the update process has not succeeded (completed), the process proceeds to step S408. The case where it is determined that the update process has not succeeded (completed) is, for example, a case where the update process does not end even if a certain time has elapsed since the start of the update process.

  In step S405, the CPU 210 executes the processing unit update program 433. Then, the CPU 210 executes a saving process for saving a program (saving information) stored in each processing unit (the printer unit 220, the scanner unit 221, the USB-FAX unit 223, and the finisher unit 222). Specifically, all programs stored in each processing unit are copied to the sub partition 402 and saved. If there is not enough free space in the subpartition 402, it may be saved in the HDD 213.

  In step S <b> 406, the CPU 210 executes a processing unit update program 433, thereby executing a program update process executed by each processing unit (printer unit 220, scanner unit 221, USB-FAX unit 223, finisher unit 222). .

  In step S407, the CPU 210 determines whether or not the program update process of each processing unit has been successful. If it is determined that the process has been successful, the process proceeds to step S407. On the other hand, if the update process has not succeeded, the process proceeds to step S409. The case where the update process is not successful is, for example, a case where the update process does not end even if a certain time has elapsed since the start of the update process. In the first embodiment, there are the printer unit 220, the scanner unit 221, the USB-FAX unit 223, and the finisher unit 222 as processing units. If any of the processing units has not been updated, step S407 is performed. This determination is NO.

  In step S <b> 408, the CPU 210 specifies that the subpartition program is to be started so that the main partition program update process is not performed at the next start because the main partition program update process has succeeded. The information for turning off the flag to be stored is stored in the SRAM 227.

  In step S409, the CPU 210 restores the program (plural subprograms) of each processing unit to the subpartition 402 with the program saved in step S405. Specifically, the program saved in the subpartition 402 is restored by copying it to the flash ROM (220b to 223b) of each processing unit. The reason for restoring in this way is that it is determined in step S407 that the update process of the program (second program) has not succeeded (completed).

  In step S410, the CPU 210 restores the program in the main partition 401 to the sub partition 402 with the program saved in step S402. Specifically, the program saved in the sub partition 402 is restored by copying it to the main partition 401. The reason for the restoration is that it is determined in step S404 or step S407 that the program update process has not succeeded (completed).

  The restoration of the program of the main partition 401 is executed when it is determined NO in step S407 even if it is determined in step S404 that the update process of the program of the main partition 401 has been successful. In step S407, NO is determined when the program update process of each processing unit has not succeeded (completed). As described above, the reason why the program of the main partition 401 is restored to the program before the update even when the program update process of the main partition 401 is successful is as follows. This is to make the combination of the program of the main partition 401 and the version of the program of each processing unit appropriate. For example, when the program of the main partition 401 is upgraded, but the program of each processing unit is not upgraded, the combination of the program of the main partition 401 and the version of the program of each processing unit is not appropriate. In this case, data transfer between the control unit 200 and each processing unit, and an instruction and response from the control unit 200 to each processing unit are not appropriately performed. Therefore, in order to prevent such incompatibility of version combinations, the program of the main partition 401 is restored to the program before the update even when the program update process of the main partition 401 is successful.

  Next, processing when the sub-partition update program for the main partition 401 is executed will be described with reference to FIG. Each process in FIG. 5 corresponds to step S604 in FIG. 6 described above.

  In step S501, the CPU 210 activates the information processing apparatus 100 in the update mode after confirming that the SRAM 227 activates the main partition program and stores a flag that designates activation in the update mode. Specifically, the CPU 210 activates the OS 411 and activates the sub-partition update program 421 by the activated OS 411.

  In step S502, the CPU 210 executes a save process for saving the program stored in the sub-partition 402. Specifically, all the programs stored in the sub partition 402 are copied to the main partition 401 and saved. If there is not enough free space in the main partition 401, it may be saved in the HDD 213. The reason for executing such a saving process is to enable restoration to the state before the update when the program update process of the subpartition 402 is not completed.

  In step S503, the CPU 210 executes the update process of each program in the subpartition 402 by executing the subpartition update program 421.

  In step S504, the CPU 210 determines whether the update process of each program in the subpartition 402 is successful. If it is determined that the update process is successful, the process proceeds to step S505. On the other hand, if the update process has not succeeded (completed), the process proceeds to step S506. Note that the case where the update process has not succeeded (completed) is, for example, a case where the update process does not end even if a certain period of time has elapsed since the start of the update process.

  In step S505, since the update processing of the subpartition program is successful, the CPU 210 starts the main partition program in the update mode so that the subpartition program update processing is not performed at the next start-up. Information for turning off the flag designating that is stored in the SRAM 227.

  In step S506, since the program update process was not successful in step S504, the CPU 210 restores the program of each processing unit to the main partition 401 with the program saved in step S502. Specifically, the program saved in the main partition 401 is restored by copying it to the sub partition 402.

  As described above, according to the first embodiment, when updating a plurality of programs executed by the information processing apparatus, even if the update process of one of the programs is not completed, the execution of another program is performed. It is possible to provide an information processing apparatus and a control method therefor so as not to be in a state where it cannot be performed. More specifically, a plurality of programs are divided into a main partition and a sub partition, and the program of the other partition is updated by the program of one partition. Thereby, even when the update process of one program is not completed, it is possible to prevent the other program from being executed.

  Further, it is specified which of the plurality of programs is to be updated, and only the process for updating the program specified as the update target is executed. As a result, it is possible to avoid wastefully executing a process of restarting the information processing apparatus 100 in order to update a program that is not an update target.
