The power supply is supplied from the commercial power source 31.

(UI52 and sub panel 80)
As shown in FIG. 2, the UI 52 installed in the upper housing 10A is provided on a plate 56 that is a separate member from the upper housing 10A. A touch panel unit 40 is disposed at the center of the plate 56. A plurality of hard keys 54A to 54E (generically referred to as hard keys 54 in FIG. 1) are exposed on the surfaces of the left and right plates 56 of FIG.

  On the other hand, a sub-panel 80 is provided on the left side of the plate 56 in FIG. In the present embodiment, the sub panel 80 is accommodated in a rectangular recess 57 provided in the upper housing 10A.

  The sub-panel 80 is provided with a display unit 88 on the surface of the cover member that covers the entire surface (as shown in FIG. 2, the upper surface when accommodated in the recessed portion 57).

  The sub-panel 80 may be fixed while being accommodated in the recessed portion 57, or may be detachable (see the imaginary line in FIG. 2). When the sub panel 80 is detachable, the wiring system corresponding to the bus 33E (see FIG. 3) that manages information communication with the image processing apparatus 10 may be wired or wireless.

In addition, when the sub panel 80 has a detachable structure, a plurality of temporary installation locations may be provided.

  In the present embodiment, the reason why the sub panel 80 distinguishes the UI 52 from the sub panel 80 is that the power supply source is different. Even when the power supply to the UI 52 is cut off, Upon receiving the supply, it plays a role of notifying notification information. The notification information to be notified will be described later.

(Control system of image processing device)
FIG. 3 is a schematic diagram of the hardware configuration of the control system of the image processing apparatus 10.

  The network line network 20 is connected to the main controller 18 of the image processing apparatus 10. The network communication line network 20 is connected to a PC (terminal device) 29 that can be a transmission source of image data.

  The main controller 18 is connected to the facsimile communication control circuit 16, the image reading unit 14, the image forming unit 12, and the UI 52 via buses 33A to 33D such as a data bus and a control bus. That is, each processing unit of the image processing apparatus 10 is controlled mainly by the main controller 18.

  Further, the main controller 18 of the present embodiment is connected to the control unit 84 of the sub panel 80 via the bus 33E.

  The image processing apparatus 10 includes a power supply device 42 and is connected to the main controller 18 by a signal harness 43.

  The power supply device 42 is supplied with electric power from the commercial power supply 31 via the input power supply line 24.

  In the power supply device 42, power supply lines 35 </ b> A to 35 </ b> D that supply power independently to the main controller 18, the facsimile communication control circuit 16, the image reading unit 14, the image forming unit 12, and the UI 52 are provided. For this reason, the main controller 18 individually supplies power to each processing unit (device) (power supply mode) or restricts power supply (energy saving mode) to enable so-called partial power saving control.

  In a general energy saving mode, the power supply to devices other than the main controller 18 is cut off, and the main controller 18 also has a function of waiting to receive information from the outside (network communication line network 20 or telephone line network 22). Power other than necessary power is cut off. In this case, about 1.5 to 5 w is consumed as electric power.

  On the other hand, in the present embodiment, as the energy saving mode, the “sleep 0” mode that basically cuts off the power supply to the main controller 18 is set.

  “Basically shutting off power supply” means that the main controller 18 does not receive any power from the commercial power supply 31 (power supply device 42), but the information reception standby function from the outside, and the “sleep 0” mode state. In order to return to the normal mode state from the power source, it means that power is supplied from a sub power source unit different from the power source device 42 as the main power source unit. The power consumption in the “sleep 0” mode is about 0.5 w compared to the general power consumption (1.5 w to 5 w), and the energy saving performance is extended. The power consumption during the “sleep 0” mode can be displayed on the display unit 88 of the sub-panel 80. In this case, if the display unit is 1w, “0w” is displayed during the “sleep 0” mode.

  In the “sleep 0” mode, for example, print information from the PC 29 and facsimile reception information in the facsimile communication control circuit 16 are received. Therefore, even if the “sleep 0” mode period is set, processing is performed during the set period. There is.

  In the “sleep 0” mode period, for example, a time period in which the usage rate of the image processing apparatus 10 is low is statistically extracted within one day, and the time period is set as a limited period (“sleep 0” mode). Thus, it is possible to improve the energy saving performance compared with continuing the normal mode.

  The “sleep 0” mode period can be freely set by the user, and is not limited to once in the above-described time period, but may be two or more times a day. Further, a plurality of image processing apparatuses 10 are linked together. When mode control is performed, the transition to the “sleep 0” mode may be set while being shifted from each other based on the power peak time period notified from the power company.

  In the present embodiment, a power supply system using photovoltaic power generation is applied as a sub power supply unit for supplying power to the main controller 18 during the “sleep 0” mode period.

  In other words, the solar panel 92 is installed in the image processing apparatus 10. For example, the solar panel 92 may be attached to all or part of the surface of the upper housing 10A or the lower housing 10B (see FIG. 1), or may be disposed away from the image processing apparatus 10. .

  The solar panel 92 is connected to the power storage device 96 via a dedicated wiring 94. The power charged in the power storage device 96 can be sent to the main controller 18 via the power supply line 98.

  The main controller 18 is provided with a power switching unit 18A and a sub controller 18S. In the power supply switching unit 18A, the power supply source is switched to the power supply device 42 (main power supply unit) in the normal mode, and is switched to the power storage device 96 (sub power supply unit) in the “sleep 0” mode.

  The sub-controller 18S is a part of the function of the main controller 18. The sub-controller 18S is activated during the “sleep 0” mode period, monitors the operation state of the power saving key, waits for information reception from the outside, and “sleep”. The program for returning from the “0” mode state to the normal mode state is executed.

  The sub controller 18S may be provided separately from the main controller 18.

  The image processing apparatus 10 according to the present embodiment includes a sub panel 80.

  As shown in FIG. 3, the sub-panel 80 is provided with a unique power storage device 82 and connected to the control unit 84 via the power supply line 35E. The power storage device 82 is charged by solar power generation by the solar panel 86.

  The sub panel 80 is provided with a display unit 88 that operates under the control of the control unit 84.

  Note that the display unit 88 uses a liquid crystal display device that does not have a backlight and has a minimum power consumption that can be conceived at present. However, depending on the amount of power stored in the power storage device 82 or the power generation capability of the solar panel 86, the backlight may be turned on. It may be a display unit 88 or an LED display unit. Furthermore, it is good also as a touchscreen type provided with the operation function.

  As described above, the sub-panel 80 does not receive power supply from the image processing apparatus 10, operates with power received from an independent power source (power storage device 82), and receives operation information (for example, received from the main controller 18 via the bus 33E). It functions as an information display device that displays information (mainly power value information) on the display unit 88 based on execution information for each device and operation mode (state) information).

(Correspondence between “sleep 0” mode and external information reception)
In the present embodiment, when any process is being executed at the start of the “sleep 0” mode period in a preset period, the end time of the process is calculated and the process ends within a predetermined allowable time. The transition to the “sleep 0” mode is delayed until the processing is completed, and when the processing is not completed, the processing is forcibly interrupted to shift to the “sleep 0” mode.

  The period set in advance may be, for example, a regular period (time period) every day or a period (time period) set irregularly. The period set irregularly includes the period set by the user and the synchronization of the peak power by the power company.

  For example, the allowable time is preferably about 5 minutes from the start of the “sleep 0” mode period. However, the allowable time is not limited, and if it is short, priority is given to energy saving, and if it is short, priority is given to convenience. What is necessary is just to set suitably according to a use environment.

  Further, the permissible time may be set for each user ID such that the permissible time is linked with the user ID (identification number), for example, the permissible time is extended for the managerial class on the organization, and the permissible time is shortened otherwise. .

  The forcibly interrupted processing is resumed when the “sleep 0” mode period ends.

  In addition, when the print information (job data) is being received and the “sleep 0” mode period start timing is reached, if the print information can be received within the allowable time, the print information is continuously received. If the reception completion is not possible, the PC 29 as the transmission source is notified to transmit the remaining information after the end of the “sleep 0” mode period, and the “sleep 0” mode period is started. Good.

  In the above description, the information received from the outside is the print instruction from the PC 29, but the present invention can also be applied to the facsimile reception and reception printing in the facsimile communication control circuit 16.

  Hereinafter, the operation of the present embodiment will be described.

  FIG. 4 is a flowchart showing an energy saving mode (“sleep 0” mode) transition control routine in the main controller 18.

  In step 100, it is determined whether or not it is the “sleep 0” mode start timing. If a negative determination is made, this routine ends. If an affirmative determination is made in step 100, the process proceeds to step 102 to determine whether or not a facsimile is received. If an affirmative determination is made in step 102, the process proceeds to step 104 to determine whether or not an emergency process is necessary. If there is no facsimile reception in step 102, the process proceeds to step 106.

  In other words, if there is facsimile reception (affirmative determination in step 102), but it is determined in step 104 that emergency processing is not required, the process proceeds to step 106.

  If there is facsimile reception (affirmative determination in step 102) and it is determined in step 104 that emergency processing is required, the process proceeds to step 114 described later.

  In step 106, it is determined whether or not any job is being executed in spite of the start time of the “sleep 0” mode.

  If an affirmative determination is made in step 106, the process proceeds to step 108, the time until the end of the job being executed is calculated, and the process proceeds to step 110. In step 110, it is determined whether or not the time until the end of the job calculated in step 108 is a time to end within the allowable time.

  If a negative determination is made in step 110, the process proceeds to step 112 to execute job forced termination processing in order to prioritize energy saving, and the process proceeds to step 118. In step 118, the process for shifting to the “sleep 0” mode is executed, and this routine ends.

  For example, when the job being executed is a print job, the forced job termination process ends the image forming process in the image forming unit 12 in units of pages, and the job data of the remaining pages is stored in the flash memory. To do. In this case, when the “sleep 0” mode ends and the normal mode is restored, the image forming process for the remaining pages may be executed, and energy savings can be maintained. The reason why the storage destination is the flash memory is that the processing time for storage is shorter than that of the hard disk.

  In addition, you may complete | finish not only in a page unit but in a copy unit.

  If the determination in step 110 is affirmative, the process proceeds to step 114 to instruct job continuation and the process proceeds to step 116 in order to give priority to convenience.

  If affirmative determination is made in step 104 described above, that is, if there is a facsimile reception and urgent processing is required, the process proceeds from step 104 to step 114, and continuation processing is instructed regardless of the allowable time.

  In step 116, it is determined whether or not the job being executed has ended. If an affirmative determination is made, the process proceeds to step 118. In step 118, the process for shifting to the “sleep 0” mode is executed, and this routine ends.

  For example, if the job being executed is a print job, and if it is completed within the allowable time, it is possible to delay the transition to the “sleep 0” mode until the image forming process for all pages is completed. Can be achieved.

  On the other hand, if a negative determination is made in step 106 whether or not any job is being executed despite the start of the “sleep 0” mode, the process proceeds to step 120.

  In step 120, it is determined whether job data for any job is being received.

  If a negative determination is made in step 120, the process proceeds to step 118, immediately performing a process for shifting to the “sleep 0” mode, and this routine ends.

  If an affirmative determination is made in step 120, the process proceeds to step 122, the time until the end of the job data reception being executed is calculated, and the process proceeds to step 124. In step 124, it is determined whether or not the time until the end of the reception of the job data calculated in step 122 is a time that ends within the allowable time.

  If a negative determination is made in step 124, the process proceeds to step 126 to execute job data reception forced termination processing in order to prioritize energy saving, and the process proceeds to step 118.

  In step 118, the process for shifting to the “sleep 0” mode is executed, and this routine ends.

  For example, if the job being executed is a print job, the forced termination process of job data reception is a process of ending and storing the data in page units. In this case, when the “sleep 0” mode ends and returns to the normal mode, it is only necessary to accept the job data of the remaining pages, and energy saving can be maintained.

  If the determination in step 124 is affirmative, the process proceeds to step 128 to instruct job data reception continuation and the process proceeds to step 116 in order to give priority to convenience.

  In step 116, it is determined whether or not the reception of the job data being executed has been completed. If an affirmative determination is made, the process proceeds to step 118. In step 118, the process for shifting to the “sleep 0” mode is executed, and this routine ends.

  For example, when the job being executed is a print job, if the job is completed within the allowable time, it is convenient to delay the transition to the “sleep 0” mode until reception of job data for all pages is completed. It becomes possible to aim at sex.

  Next, FIG. 5 is a flowchart showing a job correspondence control routine in the sub-controller 18S. That is, it corresponds to an external job in the “sleep 0” mode.

  In step 150, it is determined whether new job data has been received. If an affirmative determination is made, the process proceeds to step 152. In step 152, the job data is stored in the flash memory, and the process proceeds to step 154.

  The reason for storing in the flash memory is that, for example, the storage processing time is shorter than that of other recording media such as a hard disk, so that the power consumption of the sub-controller 18S activated by the power of the power storage device 82 is reduced. If the power storage device 82 is sufficiently charged, the present invention is not limited to the flash memory.

  In the present embodiment, it is assumed that new job data is received. However, the new job data may not be received at all. In this case, it is preferable to notify the transmission source PC 29 that the retransmission is performed after the “sleep 0” mode ends without performing the retry process based on the transmission failure (retry unnecessary notification + retransmission reservation notification).

  Further, when the storage capacity of the flash memory becomes full, the remainder may be handled as a retry unnecessary notification + a retransmission reservation notification.

  In step 154, the received job information (received job information) is displayed on the display unit 88 of the sub-panel 80, and the process proceeds to step 156.

  By displaying the received job information (notification information) on the sub-panel 80, the user is notified that the job has been received without activating the main controller 18.

  In step 156, it is determined whether there is an urgent instruction in the received job information. That is, an emergency flag is set in the received job information, and if the emergency flag is set, an affirmative determination is made in step 156.

  If an affirmative determination is made in step 156, it is determined that the received job information needs to be urgently executed in spite of the “sleep 0” mode, the process proceeds to step 158, and the emergency process is executed. The

  In the emergency processing at step 158, for example, the control unit 84 of the sub-panel 80 recognizes this, and the display unit 88 displays notification information for a job that needs to be processed urgently.

  The specific user views the notification information and operates an instruction button (not shown) provided on the sub-panel 80 to activate the main controller 18 and, after the specific user authentication process, start up the device and perform emergency processing. Instruct.

  In the image processing apparatus 10, the emergency process is executed based on the received job information, and then returns to the “sleep 0” mode again, and proceeds to step 160.

  On the other hand, if a negative determination is made in step 150, the process proceeds to step 160.

  In step 160, it is determined whether or not the “sleep 0” mode has ended. If an affirmative determination is made, the process proceeds to step 162, the main controller 18 is activated, and the transition to the normal mode is instructed. The routine ends. If the determination in step 160 is negative, the “sleep 0” mode is maintained and the routine ends.

  When there is a transition to the normal mode, the main controller 18 secures free space in the flash memory by transferring the information stored in the flash memory during the “sleep 0” mode to the hard disk drive. It is preferable to prepare for the next “sleep 0” mode.

  In addition, the processing of a job forcibly terminated before shifting to the “sleep 0” mode or the processing of job data received during the “sleep 0” mode has priority over the job received when returning to the normal mode. It is preferable to process.

  According to the present embodiment, in principle, energy saving is improved by providing a period of transition to the “sleep 0” mode (a limit period in which all processes are prohibited in advance), and processing is performed at the start of the limit period. If the process is continued, it is determined whether to shift the mode after delaying the “sleep 0” mode shift timing depending on the end timing of the process, or to immediately shift the mode by forcibly terminating the process. I did it. For this reason, exceptionally convenient measures are taken, and it is possible to achieve both energy saving and convenience.

  Further, in the “sleep 0” mode, “0w” is displayed on the sub-panel 80, so that the user can recognize that the power consumption is 0 without removing the outlet 26. Since the outlet 26 is not pulled out, emergency response (emergency facsimile reception, etc.) is possible.

  In the present embodiment, the process restriction on the print instruction in the “sleep 0” mode period in the energy saving mode has been described. However, the process restriction on the print instruction is not limited to the “sleep 0” mode period, but “sleep 0”. The present invention can also be applied during an off mode period deeper than the mode (with less power consumption) or during a normal energy saving mode that does not use the sub power supply unit.
