  The WOL setting availability information setting unit 701 sets WOL setting availability information indicating whether or not to set a WOL.

  The state control unit 702 accepts a shutdown start request for requesting to stop power supply to at least the controller 100 while continuing power supply to at least the low power device microcomputer 500, and the WOL setting availability information sets WOL. (In this example, the WOL valid bit is set in the NVRAM 130) At least the power supply to the controller 100 is stopped and the power supply to each of the PHY 172 and the low-power device microcomputer 500 is continued (composite) Control to shift to the WOL standby state indicating the state of the machine 1 is performed.

  The display control unit 705 performs control to display various types of information on the LCD 210 of the operation panel 200. As will be described in detail later, when the WOL setting control unit 703 performs control to set the WOL, the display control unit 705 performs control to display on the LCD 210 that the WOL is being set. Further, the display control unit 705 starts power supply from an external power source without generating a signal (for example, a button press notification signal described later or a WOL notification signal described later) that triggers the start of power supply, and When the WOL setting valid information is not set (that is, in the case of unexpected start-up), control is performed to display on the LCD 210 that the shutdown is performed as it is.

  As will be described in detail later, in the present embodiment, power supply from an external power source to the low power device microcomputer 500 is started with connection of the power plug 620 or recovery from a power failure, and the WOL is stored in the FRAM (registered trademark) 504. When a valid bit (an example of WOL setting valid information) is stored, the low power device microcomputer 500 starts power supply to at least the controller 100, and the WOL setting control unit 703 performs control to set the WOL. After the WOL setting control unit 703 performs control to set the WOL, the state control unit 702 performs control to shift the state of the multifunction machine 1 to the WOL standby state.

  In the present embodiment, the functions of the WOL setting availability information setting unit 701, the state control unit 702, the WOL setting control unit 703, and the display control unit 705 are realized by the controller 100, but are not limited thereto. Absent. Here, the functions of the WOL setting availability information setting unit 701, state control unit 702, WOL setting control unit 703, and display control unit 705 described above are stored in the NAND flash memory 150 or the like by the CPU 110 of the controller 100, for example. It is realized by executing the program. In this example, the function of the above-described WOL setting availability information setting unit 701 is provided by the state management module 30, the function of the above-described state control unit 702 is provided by the state control driver 14, and the function of the above-described WOL setting control unit 703. Is provided by the NIC driver 12, and the function of the above-described display control unit 705 is provided by the state management module 30, but is not limited thereto. For example, at least a part of the functions of the above-described WOL setting availability information setting unit 701, state control unit 702, WOL setting control unit 703, and display control unit 705 is performed by a dedicated hardware circuit (for example, a semiconductor integrated circuit). It may be realized.

  In the present embodiment, the function of the above-described WOL setting effective information storage control unit 704 is realized by the low power device microcomputer 500. Here, the function of the above-described WOL setting effective information storage control unit 704 is realized by the CPU 501 of the low-power device microcomputer 500 executing a program stored in the ROM 503 or the like, for example. The function of the WOL setting effective information storage control unit 704 may be realized by a dedicated hardware circuit (for example, a semiconductor integrated circuit).

  Hereinafter, a specific operation example of the MFP 1 according to the present embodiment will be described. FIG. 5 is a flowchart illustrating an operation example of the multi-function device 1 when determining whether or not WOL setting is possible. First, the display control unit 705 performs control to display a setting screen for receiving an instruction to set the WOL on the LCD 210 of the operation panel 200 in accordance with a user operation (step S1). Next, when an instruction to set the WOL is received (step S2: Yes), the WOL setting availability information setting unit 701 (state management module 30) sets the WOL valid bit in the NVRAM 130 (step S3). On the other hand, when an instruction not to set the WOL is received (step S2: No), the WOL setting availability information setting unit 701 (state management module 30) does not set the WOL effective bit in the NVRAM 130, but sets the WOL effective bit in the NVRAM 130. Clear (step S4). The type of the application 40 that can set the WOL is arbitrary, and may be any of a copy application, a printer application, a fax application, and a scanner application.

  FIG. 6 is a flowchart illustrating an operation example of the multifunction machine 1 at the time of shutdown. First, the state control driver 14 detects pressing of the power button 610 (step S11). In the present embodiment, when the user presses the power button 610 at least in a state where power is supplied to the controller 100 (for example, a steady state described later), the power button 610 of the general-purpose ports for input / output of the ASIC 140 The voltage of the signal (power button signal) supplied to the signal line connected to the port corresponding to the pressing changes to a voltage indicating the occurrence of pressing of the power button 610. The state control driver 14 can detect the pressing of the power button 610 by reading the voltage of the port corresponding to the button pressing among the general-purpose ports for input / output of the ASIC 140. Next, the state control driver 14 notifies the state management module 30 that the power button 610 has been pressed (step S12).

  Next, the state management module 30 requests each application 40 to stop control (step S13), and prompts the transition to a state where shutdown can be started. In this example, the shutdown is a process of stopping power supply to at least the controller 100 while continuing power supply to at least the low power device microcomputer 500.

  After confirming that each application 40 has transitioned to a state where shutdown can be started, the state management module 30 outputs a shutdown start request to the state control driver 14 (step S14). The state control driver 14 that has received the shutdown start request checks the NVRAM 130 (step S15). If the above-described WOL valid bit is set (set) in the NVRAM 130 (step S16: Yes), the state control driver 14 determines that the NIC is NIC. The driver 12 is requested to set the WOL (request to enable the WOL setting) (step S17). Upon receiving this request, the NIC driver 12 sets its own MAC address (MAC address of the multifunction device 1) in the WOL address register of the PHY 172 (step S18). Next, the NIC driver 12 sets the enable bit of the WOL valid register of the PHY 172 (step S19) and notifies the state control driver 14 of completion.

  Receiving the completion notification from the NIC driver 12, the state control driver 14 sets a WOL setting valid signal indicating that the WOL setting is valid (step S20). For example, the state control driver 14 sets the voltage of the port corresponding to the WOL setting valid signal among the input / output general-purpose ports of the ASIC 140 to a voltage (predetermined voltage) indicating the generation of the WOL setting valid signal. , The WOL setting valid signal can be set. Further, the state control driver 14 sets a microcomputer monitoring valid signal indicating that power monitoring is transferred to the low power device microcomputer 500 as information for transferring power monitoring to the low power device microcomputer 500 (step S21). For example, the state control driver 14 sets the voltage of the port corresponding to the microcomputer monitoring valid signal among the general-purpose ports for input / output of the ASIC 140 to a voltage (predetermined voltage) indicating the generation of the microcomputer monitoring valid signal. The microcomputer monitoring valid signal can be set.

  After the above-described step S21, the state control driver 14 stops the power supply to each of the controller 100, the operation panel 200, the FCU 300, and the engine unit 400 (the power is turned off) (step S22). In this embodiment, the state control driver 14 changes the voltage of the port corresponding to the signal for controlling the signal for controlling the controller control SW 101 among the general-purpose ports for input / output of the ASIC 140 to the controller control SW 101 to OFF. By setting the voltage, the controller control SW 101 can be turned off, and the power supply to the controller 100 can be stopped. Similarly, the state control driver 14 sets the voltage of the port corresponding to the signal for controlling the operation panel control SW 230 among the general-purpose ports for input / output of the ASIC 140 to the voltage for switching the operation panel control SW 230 to OFF. Then, the voltage of the port corresponding to the signal for controlling the FCU control SW 310 is set to a voltage causing the FCU control SW 310 to transition to OFF, and the port corresponding to the signal for controlling the engine control SW 410 is set to the engine control SW 410. Is set to a voltage for transitioning to OFF.

  As described above, when the WOL is set and shut down, as shown in FIG. 7, the state of the multi-function device 1 is that the power supply to each of the low-power device microcomputer 500 and the PHY 172 is continued, but the other elements The power supply to (the controller 100 or the like) is stopped. In the present embodiment, the state shown in FIG. 7 is referred to as a “WOL standby state”. In the WOL standby state, energization to the PHY 172 is continued, so that the PHY 172 can notify the low power device microcomputer 500 of the WOL signal by receiving the magic packet. Then, the low-power device microcomputer 500 restarts the power supply to each unit (at least an element other than the low-power device microcomputer 500 and the PHY 172) by detecting the pressing of the power button 610 or the generation of the WOL signal. Can do.

  Returning to FIG. 6, the description will be continued. If the above-described WOL valid bit is not set in the NVRAM 130 in step S16 described above (step S16: No), the state control driver 14 requests the NIC driver 12 to invalidate the WOL setting (step S16). S23). Upon receiving this request, the NIC driver 12 stops the power supply to the PHY 172 (turns off the power) (step S24). Next, the state control driver 14 clears the WOL setting valid signal (step S25). For example, the state control driver 14 changes the voltage of the port corresponding to the WOL setting valid signal among the input / output general-purpose ports of the ASIC 140 to a voltage (predetermined voltage) indicating that the WOL setting valid signal is not generated. By setting, the WOL setting valid signal can be cleared. Then, the state control driver 14 sets a microcomputer monitoring valid signal indicating that power monitoring has been transferred to the low power device microcomputer 500 as information for transferring power monitoring to the low power device microcomputer 500 (step S26).

  After the above-described step S26, the state control driver 14 stops the power supply (turns off the power) to each of the controller 100, the operation panel 200, the FCU 300, and the engine unit 400 (step S22). As described above, when the shutdown is performed without setting the WOL, as shown in FIG. 8, in the state of the multi-function device 1, the power supply to only the low-power device microcomputer 500 is continued, while other elements (controllers) 100 etc.) is stopped. When the state is shifted to this state, the low power device microcomputer 500 can restart the power supply to each unit (at least an element other than the low power device microcomputer 500) of the multifunction device 1 by detecting the pressing of the power button 610. .

  Next, the operation of the low power device microcomputer 500 after shutdown will be described. FIG. 9 is a flowchart showing an operation example of the low-power device microcomputer 500 after shutdown. First, the low power device microcomputer 500 confirms a set of microcomputer monitoring valid signals (step S31). For example, the low power device microcomputer 500 can confirm the set of the microcomputer monitoring effective signal by reading the voltage of the port corresponding to the microcomputer monitoring effective signal in the GPIO 506. Next, the low-power device microcomputer 500 (WOL setting effective information storage control unit 704) checks whether or not the WOL setting effective signal is set (step S32). For example, the low-power device microcomputer 500 can check whether the WOL setting valid signal is set by reading the voltage of the port corresponding to the WOL setting valid signal in the GPIO 506.

  When the WOL setting valid signal is set (step S32: Yes), the low power device microcomputer 500 (WOL setting valid information storage control unit 704) interprets that the WOL has been set and shut down, and the internal FRAM (registered) A WOL valid bit indicating that the WOL has been set is set (set) in the trademark 504 (step S33). On the other hand, when the WOL setting valid signal is not set in step S32 described above (step S32: No), the low-power device microcomputer 500 does not set the WOL valid bit in the internal FRAM (registered trademark) 504. Instead, the WOL valid bit in the internal FRAM (registered trademark) 504 is cleared (step S34).

  Thereafter, the low-power device microcomputer 500 starts monitoring the power-on event of the multifunction device 1. First, the low power device microcomputer 500 checks whether or not the power button 610 has been pressed (step S35). For example, the low power device microcomputer 500 monitors the voltage of the port corresponding to the pressing of the power button 610 in the GPIO 506 and confirms whether or not the voltage of the port has changed to a voltage indicating the occurrence of the button pressing. It can be confirmed whether or not the power button 610 has been pressed.

  When the power button 610 is pressed (step S35: Yes), the low power device microcomputer 500 sets a button pressing notification signal (step S36). For example, the low power device microcomputer 500 sets the voltage of the port corresponding to the button press notification signal in the GPIO 506 to a voltage (predetermined voltage) indicating the generation of the button press notification signal. Next, the low power device microcomputer 500 clears the WOL notification signal (step S37). For example, the low power device microcomputer 500 sets the voltage of the port corresponding to the WOL notification signal in the GPIO 506 to a voltage indicating that no WOL notification signal is generated.

  After step S37 described above, the low-power device microcomputer 500 starts supplying power (turns on the power) to each of the controller 100, the operation panel 200, the FCU 300, and the engine unit 400 (step S38). In the present embodiment, the low-power device microcomputer 500 sets the voltage of the port corresponding to the relay signal in the GPIO 506 to a voltage that makes the relay SW 102 transition to ON. As a result, the relay SW 102 is turned on, and the controller control SW 101, the operation panel control SW 230, the FCU control SW 310, and the engine control SW 410 are turned on in conjunction with the relay SW 102 being turned on. Thereby, power supply to each of controller 100, operation panel 200, FCU 300, and engine unit 400 is started.

  On the other hand, when the power button 610 is not pressed in step S35 described above (step S35: No), the low power device microcomputer 500 checks whether the WOL signal is set by the PHY 172 (step S39). For example, the low power device microcomputer 500 monitors the voltage of the port corresponding to the WOL signal in the GPIO 506 and checks whether the voltage of the port is a voltage indicating the generation of the WOL signal. It can be confirmed whether or not it has been set.

  When the WOL signal is set (step S39: Yes), the low power device microcomputer 500 clears the button press notification signal (step S40). For example, the low-power device microcomputer 500 sets the voltage of the port corresponding to the button press notification signal in the GPIO 506 to a voltage indicating that the button press notification signal is not generated. Next, the low power device microcomputer 500 sets a WOL notification signal (step S41). For example, the low power device microcomputer 500 sets the voltage of the port corresponding to the WOL notification signal in the GPIO 506 to a voltage indicating that the WOL notification signal is generated. Then, the low power device microcomputer 500 starts supplying power (turns on the power) to each of the controller 100, the operation panel 200, the FCU 300, and the engine unit 400 (step S38).

  Next, the operation of the low power device microcomputer 500 when the power supply from the external power source to the low power device microcomputer 500 is started with the connection of the power plug 620 or the recovery from the power failure will be described. FIG. 10 is a flowchart showing an operation example of the low-power device microcomputer 500 when the power supply from the external power source to the low-power device microcomputer 500 is started with the connection of the power plug 620 or the recovery from the power failure. As shown in FIG. 10, the low-power device microcomputer 500 first confirms energization to itself (step S51). Next, the low-power device microcomputer 500 confirms the internal FRAM (registered trademark) 504 (step S52), and confirms whether or not the WOL valid bit is set (set) in the FRAM (registered trademark) 504 (step S52). Step S53).

  When the WOL effective bit is set in the FRAM (registered trademark) 504 (step S53: Yes), the low-power device microcomputer 500 resets the WOL effective bit because the power supply is shut off with the WOL effective bit set. It is determined that setting is necessary, and activation of the multifunction device 1 is started. At this time, the low-power device microcomputer 500 clears the button press notification signal (step S54) and clears the WOL notification signal in order to notify the multifunction device activation unit 20 of the activation method of the multifunction device 1. S55). For example, the low-power device microcomputer 500 clears the button press notification signal by setting the voltage of the port corresponding to the button press notification signal in the GPIO 506 to a voltage indicating that the button press notification signal is not generated. Can do. For example, the low power device microcomputer 500 can clear the WOL notification signal by setting the voltage of the port corresponding to the WOL notification signal in the GPIO 506 to a voltage indicating that the WOL notification signal is generated. it can.

  Next, the low-power device microcomputer 500 starts power supply (turns on the power) to each of the controller 100, the operation panel 200, the FCU 300, and the engine unit 400 (step S56). As described above, in this embodiment, the low-power device microcomputer 500 sets the voltage of the port corresponding to the relay signal in the GPIO 506 to a voltage that makes the relay SW 102 transition to ON. As a result, the relay SW 102 is turned on, and the controller control SW 101, the operation panel control SW 230, the FCU control SW 310, and the engine control SW 410 are turned on in conjunction with the relay SW 102 being turned on. As a result, power supply to each of the controller 100, the operation panel 200, the FCU 300, and the engine unit 400 is started (resumed).

  On the other hand, if the WOL valid bit is not set in the FRAM (registered trademark) 504 in step S53 described above (step S53: No), the low-power device microcomputer 500 determines that the WOL setting is not necessary, It is confirmed whether or not the button 610 has been pressed (step S57). When the power button 610 is pressed (step S57: Yes), the low power device microcomputer 500 sets a button pressing notification signal (step S58). For example, the low power device microcomputer 500 sets the voltage of the port corresponding to the button press notification signal in the GPIO 506 to a voltage indicating the generation of the button press notification signal. Next, the low power device microcomputer 500 clears the WOL notification signal (step S59). For example, the low power device microcomputer 500 sets the voltage of the port corresponding to the WOL notification signal in the GPIO 506 to a voltage indicating that no WOL notification signal is generated. Next, the low-power device microcomputer 500 starts power supply (turns on the power) to each of the controller 100, the operation panel 200, the FCU 300, and the engine unit 400 (step S60).

  Next, the operation of the multifunction device 1 when power supply to the controller 100 is started will be described. FIG. 11 is a flowchart illustrating an example of processing performed by the multifunction machine starting unit 20 when power supply to the controller 100 is started. As shown in FIG. 11, first, the multifunction machine starting unit 20 clears the microcomputer monitoring valid signal (step S61). For example, the multifunction machine starting unit 20 sets the voltage of the port corresponding to the microcomputer monitoring valid signal among the input / output general-purpose ports of the ASIC 140 to a voltage indicating that the microcomputer monitoring valid signal is not generated. Next, the multifunction machine starting unit 20 checks whether or not a button press notification signal is set (step S62). For example, the MFP starter 20 checks whether the voltage of the port corresponding to the button press notification signal among the general-purpose ports for input / output of the ASIC 140 is a voltage indicating the generation of the button press notification signal. It can be confirmed whether or not a button press notification signal is set.

  If the button press notification signal is not set (step S62: No), the multi-function device activation unit 20 checks whether or not the WOL notification signal is set (step S63). For example, the MFP starter 20 confirms whether or not the voltage of the port corresponding to the WOL notification signal among the input / output general-purpose ports of the ASIC 140 is a voltage indicating the generation of the WOL notification signal. It can be checked whether the signal is set.

  When the button press notification signal is set (step S62: Yes), or when the WOL notification signal is set (step S63: Yes), the multi-function device activation unit 20 determines that the activation is normal. First, the button press notification signal and the WOL notification signal are cleared and returned to the initial state (step S64). For example, the multifunction machine starting unit 20 sets the voltage of the port corresponding to the button press notification signal among the input / output general-purpose ports of the ASIC 140 to a voltage indicating that the button press notification signal is not generated, and notifies the WOL notification. By setting the voltage of the port corresponding to the signal to a voltage indicating that the WOL notification signal is not generated, the initial state is restored.

  Next, the multifunction machine starting unit 20 reads the setting file (step S65) and starts in the normal starting mode (step S66). Details of the setting file will be described later. In this example, when activated in the normal activation mode, as shown in FIG. 12, the state of the multifunction device 1 is a state in which all elements included in the multifunction device 1 are energized (here, “steady state”). (Referred to as). In the steady state, since the microcomputer monitoring valid signal is cleared, the low power device microcomputer 500 does not perform power supply monitoring or the like (does nothing). Therefore, pressing of the power button 610 is detected not by the low-power device microcomputer 500 but by the state control driver 14 by monitoring a port corresponding to pressing of the power button 610 among general-purpose ports for input / output of the ASIC 140.

  Returning to FIG. 11, the description will be continued. If the button press notification signal is not set (step S62: No) and the WOL notification signal is not set (step S63: No), the multi-function peripheral activation unit 20 checks the NVRAM 130 of the controller 100 (step S63). S67), it is confirmed whether or not the WOL valid bit is set in the NVRAM 130 (step S68).

  If the WOL valid bit is set (step S68: Yes), the multi-function apparatus activation unit 20 determines that the activation is for resetting the WOL, and first clears the button press notification signal and the WOL notification signal. The initial state is restored (step S69). Next, the multifunction machine starting unit 20 reads the setting file (step S70) and starts in the WOL resetting mode (step S71).

  On the other hand, if the WOL valid bit is not set in the above-described step S68 (step S68: No), the multi-function peripheral activation unit 20 determines that the activation is unexpected, and first, a button press notification signal and a WOL notification signal. Is returned to the initial state (step S72). Next, the multifunction machine starting unit 20 reads the setting file (step S73) and starts up in the immediate shutdown mode (step S74).

  FIG. 13 is a diagram illustrating an example of a setting file. In this example, processing is performed in accordance with the description of the normal label for the normal activation mode, the reset_wol label for the WOL resetting mode, and the unknown label (meaning an unknown state) for the immediate shutdown mode. The normal startup mode starts all software including the application 40 and the state management module 30, the WOL reconfiguration mode starts only the statemanager with the -w option, and the immediate shutdown mode starts only the statemanager with the -s option. Switching behavior. It should be noted that statemanager is the state management module 30, and when started with the -w option, as shown in FIG. 14, the fact that WOL is being set is displayed on the LCD 210, and the shutdown process after step S13 in FIG. To implement. Further, in the case of starting with the -s option, as shown in FIG. 15, the fact that an unexpected start has occurred and an immediate shutdown is displayed on the LCD 210, and the shutdown process after step S13 in FIG. 6 is performed. . When the time until shutdown is short, the display on the LCD 210 may not be performed.

  As described above, in this embodiment, when the WOL standby state is entered, the WOL valid bit indicating that the WOL has been set is stored in the FRAM (registered trademark) 504 inside the low-power device microcomputer 500. . As a result, even when the external power supply is shut down, the WOL valid bit stored in the FRAM (registered trademark) 504 inside the low-power device microcomputer 500 is used to restore the power-on state by the WOL at the time of recovery. be able to. More specifically, as described above, the power supply from the external power source to the low power device microcomputer 500 is started with the connection of the power plug 620 or the recovery from the power failure, and the FRAM in the low power device microcomputer 500 is started. When the WOL valid bit is stored in (registered trademark) 504, the low power device microcomputer 500 starts supplying power to each of the controller 100, the operation panel 200, the FCU 300, and the engine unit 400, and the WOL setting control unit 703 ( The NIC driver 12) performs control for setting the WOL. After the WOL is set, the state control unit 702 (state control driver 14) performs control to shift the state of the multifunction device 1 to the WOL standby state again. As described above, even if the external power supply is shut off in a state where the WOL is set, the power can be turned on by the WOL.

(Second Embodiment)
Next, a second embodiment will be described. A description of portions common to the above-described first embodiment is omitted. FIG. 16 is a diagram illustrating an example of a hardware configuration of the MFP 1 according to the present embodiment. In this embodiment, the low-power device microcomputer 500 can perform ON / OFF switching of each of the FCU control SW 310 and the engine control SW 410.

  FIG. 17 is a flowchart showing an operation example of the low-power device microcomputer 500 when power supply from an external power source to the low-power device microcomputer 500 is started with the connection of the power plug 620 or recovery from a power failure. Since processing other than step S86 in FIG. 17 is the same as that in FIG. 10, detailed description thereof is omitted. In step S86 of FIG. 17, the low-power device microcomputer 500 performs control for switching the relay SW 102 to ON in a state where control for switching each of the FCU control SW 310 and the engine control SW 410 to OFF is performed. As a result, each of the controller control SW 101 and the operation panel control SW 230 is turned on, while each of the FCU control SW 310 and the engine control SW 410 is kept off. Therefore, as shown in FIG. The state 1 shifts to a state where power supply to each of the controller 100 and the operation panel 200 is started and power supply to each of the FCU 300 and the engine unit 400 is stopped.

  In short, the power supply from the external power source to the low power device microcomputer 500 is started with the connection of the power plug 620 or the recovery from the power failure, and the WOL effective bit is stored in the FRAM (registered trademark) 504 inside the low power device microcomputer 500. Is stored, the low-power device microcomputer 500 only needs to start supplying power to at least the controller 100 in order to reset the WOL.

(Third embodiment)
Next, a third embodiment will be described. A description of portions common to the above-described first embodiment is omitted. FIG. 19 is a diagram illustrating an example of a hardware configuration of the MFP 1 according to the present embodiment. In this embodiment, the low-power device microcomputer 500 can perform ON / OFF switching of each of the operation panel control SW 230, the FCU control SW 310, and the engine control SW 410.

  FIG. 20 is a flowchart illustrating an operation example of the low-power device microcomputer 500 when power supply from an external power source to the low-power device microcomputer 500 is started with the connection of the power plug 620 or the recovery from a power failure. Since the processing other than step S106 in FIG. 20 is the same as that in FIG. 10, detailed description thereof is omitted. In step S106 of FIG. 20, the low-power device microcomputer 500 switches the relay SW 102 to ON in a state in which each of the operation panel control SW 230, the FCU control SW 310, and the engine control SW 410 is controlled to be turned OFF. Take control. As a result, the controller control SW 101 is turned on, while the operation panel control SW 230, the FCU control SW 310, and the engine control SW 410 are each kept OFF. As shown in FIG. The state transitions to a state in which power supply to the controller 100 is started and power supply to each of the operation panel 200, FCU 300, and engine unit 400 is stopped.

  In short, the power supply from the external power source to the low power device microcomputer 500 is started with the connection of the power plug 620 or the recovery from the power failure, and the WOL effective bit is stored in the FRAM (registered trademark) 504 inside the low power device microcomputer 500. Is stored, the low-power device microcomputer 500 only needs to start supplying power to at least the controller 100 in order to reset the WOL. In this case, the low power device microcomputer 500 does not supply power to the operation panel 200. Further, for example, the multifunction device 1 further includes an expansion processing unit (an apparatus for providing an optional function) that expands information processing, and the low-power device microcomputer 500 does not supply power to the expansion processing unit. There may be. As a result, it is possible to suppress noise caused by unnecessary power consumption and initial processing of unnecessary parts.

(Fourth embodiment)
Next, a fourth embodiment will be described. A description of portions common to the above-described first embodiment is omitted. FIG. 22 is a diagram illustrating an example of the functions of the multifunction machine 1 according to the present embodiment. As illustrated in FIG. 22, the multifunction machine 1 further includes an abnormal activation information setting unit 706. The abnormal activation information setting unit 706 starts the power supply from the external power source without generating a signal for starting the power supply, and the WOL setting valid information (WOL valid bit in this example) is set. If there is no error (that is, if an unexpected startup is performed), check whether abnormal startup information indicating abnormal startup (in this example, referred to as “abnormal startup bit”) has been set. If the activation bit has not been set, control is performed to set the abnormal activation bit. In this example, the function of the abnormal activation information control unit 706 is provided by the multifunction device activation unit 20, but is not limited thereto.

  Further, when the abnormal activation information setting unit 706 performs control to set the abnormal activation bit (that is, at the first unexpected activation), the display control unit 705 performs control to display on the LCD 210 that the shutdown is performed. . Further, when the abnormal activation information control unit 706 does not perform control for setting the abnormal activation bit and the abnormal activation bit has already been set (that is, at the second or subsequent unexpected activation), the display control unit 705 Then, control is performed to display on the LCD 21 that there is an abnormal state.

  FIG. 23 is a flowchart illustrating an example of processing performed by the multifunction machine starting unit 20 according to the present embodiment when power supply to the controller 100 is started. The processing contents of steps S121 to S128 in FIG. 23 are the same as the processing contents of steps S61 to S68 shown in FIG. In the example of FIG. 23, when the result of step S128 is negative (step S128: No), the multi-function device activation unit 20 confirms the NVRAM 130 (step S133) and confirms whether the abnormal activation bit is set. (Step S134). If the result of step S134 is negative (step S134: No), this is the first unexpected activation, and the multifunction device activation unit 20 sets the abnormal activation bit in the NVRAM 130 (step S138). The processing contents of the subsequent steps S139 to S141 are the same as the processing contents of steps S72 to S74 shown in FIG.

  On the other hand, if the result of step S134 described above is affirmative (step S134: Yes), this is an unexpected start after the second time, and the MFP starter 20 first clears the button press notification signal and the WOL notification signal. Then, the initial state is restored (step S135). Next, the multifunction machine starting unit 20 reads the setting file (step S136) and starts the application in the abnormal stop mode (step S137). In this case, a shutdown process is performed.

  If the result of step S128 is affirmative (step S128: Yes), the multi-function peripheral activation unit 20 clears the abnormal activation bit (step S129). As a result, the abnormal activation bit is always cleared in the case of normal activation. The processing contents of steps S130 to S132 are the same as the processing contents of steps S69 to S71 shown in FIG.

  FIG. 24 is a diagram illustrating an example of a setting file according to the present embodiment. In this example, the normal startup mode is processed according to the description of the normal label, the WOL resetting mode is reset_wol label, the immediate shutdown mode is the unknown label (meaning an unknown state), and the abnormal stop mode is processed according to the description of the boot_strange label. Abnormal stop mode is different from immediate shutdown mode in that statemanager is started with the -e option. Note that statemanager is the state management module 30, and the system is stopped by displaying an abnormal stop on the LCD 210 with the -e option. FIG. 25 is a diagram illustrating an example of an abnormal stop display.

(Fifth embodiment)
Next, a fifth embodiment will be described. A description of portions common to the above-described first embodiment is omitted. FIG. 26 is a diagram illustrating an example of the functions of the multifunction machine 1 according to the present embodiment. As shown in FIG. 26, the multifunction machine 1 further includes a WOL automatic reset information setting unit 707. The WOL automatic reset information setting unit 707 maintains the WOL setting valid information (in this example, the WOL valid bit) even after shutdown according to the user's operation (specifically, the low power device microcomputer in which power supply is continued) 500 WOL automatic reset information (in this example, referred to as “WOL automatic reset bit”) indicating that the internal FRAM (registered trademark) 504 is maintained). In this example, in this embodiment, the function of the WOL automatic reset information setting unit 707 is provided by the state management module 30, but is not limited thereto. When the WOL automatic reset bit is not set when the state control unit 702 receives a shutdown request, the state control unit 702 does not store the WOL valid bit in the nonvolatile memory (in this example, the internal FRAM (registered trademark) 504). I do.

  FIG. 27 is a flowchart illustrating an operation example of the multifunction machine 1 when various settings are performed in accordance with user operations. The processing contents of steps S151 to S154 shown in FIG. 27 are the same as the processing contents of steps S1 to S4 shown in FIG. When an instruction to automatically reset the WOL is received in step S155 (step S155: Yes), the WOL automatic reset information setting unit 707 sets the WOL automatic reset bit in the NVRAM 130 (step S156). On the other hand, when an instruction to automatically reset the WOL is not received (step S155: No), the WOL automatic reset information setting unit 707 does not set the WOL automatic reset bit in the NVRAM 130 (WOL automatic reset bit). Can be cleared), the process ends.

  FIG. 28 is a flowchart illustrating an operation example of the multifunction machine 1 at the time of shutdown. The processing contents of steps S161 to S169 are the same as the processing contents of steps S11 to S19 shown in FIG. After step S169, the state control driver 14 checks the NVRAM 130 (step S170). If the above-described WOL automatic reset bit is set (set) in the NVRAM 130 (step S171: Yes), the state control driver 14 determines the WOL. A setting valid signal is set (step S172). The processing content of step S172 is the same as the processing content of step S20 shown in FIG. On the other hand, when the above-mentioned WOL automatic reset bit is not set (set) in the NVRAM 130 (step S171: No), the state control driver 14 skips the above-described step S172 and sets the microcomputer monitoring valid signal. (Step S173). That is, before setting a trigger for requesting the low-power device microcomputer 500 to set the WOL effective bit in the internal FRAM (registered trademark) 504 (without setting it), the microcomputer monitoring effective signal is set (registered trademark). 504. Accordingly, in the operation of the low power device microcomputer 500 when the power supply from the external power source to the low power device microcomputer 500 is started with the connection of the power plug 620 or the recovery from the power failure, the operation of step S53 shown in FIG. The result is always negative, and the power is not turned on without permission (without pressing the power button).

  In addition, the processing content of step S174-step S178 is the same as the processing content of step S22-step S26 shown in FIG.

(Sixth embodiment)
Next, a sixth embodiment will be described. A description of portions common to the above-described first embodiment is omitted. In this embodiment, the low-power device microcomputer 500 sets the WOL valid bit in the non-volatile memory (WOL) when the pressing time of the power button used as a trigger for starting the power supply from the external power supply is equal to or greater than the threshold in the WOL standby state. In this example, control for erasing from the internal FRAM (registered trademark) 504 of the low power device microcomputer 500 is performed.

  FIG. 29 is a flowchart showing an operation example of the low power device microcomputer 500 of the present embodiment after shutdown. The processing contents of steps S181 to S185 are the same as the processing contents of steps S31 to S35 shown in FIG. If the result of step S185 is affirmative (step S185: Yes), after waiting for 100 ms (step S186), it is confirmed whether the power button 610 has been pressed (step S187). When the result of step S187 is affirmative (step S187: Yes), the pressing time (duration of the operation of pressing the power button 610) has reached 5 seconds (an example of “threshold”, but is not limited thereto). Whether or not (step S188). If the result of step S187 is negative (step S187: No), it is determined that it is not a long press (determined as a normal pressing operation of the power button 610), and the process proceeds to step S190.

  If the result of step S188 is affirmative (step S188: Yes), the low-power device microcomputer 500 clears the WOL valid bit of the internal FRAM (registered trademark) 504 (step S189), and the process returns to step S185. If the result of step S188 is negative (step S188: No), the process proceeds to step S186.

  Note that the processing contents of steps S190 to S195 shown in FIG. 29 are the same as the processing contents of steps S36 to S41 shown in FIG.
