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 are exposed on the surfaces of the left and right plates 56 in FIG.

  The hard keys 54A to 54E are used to determine predetermined instruction information by a pressing operation, for example, a menu key 54A for transitioning the display screen of the touch panel unit 40 to a basic screen, and a copy key. A copy key 54B, a ten key 54C for designating the number of copies, inputting a recitation number, a power saving key 54D for instructing or canceling power saving, and a start key 54E for instructing execution of processing.

  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.

  The attachment position of the sub-panel 80 is not limited, and the sub-panel 80 may be attached to any one of the UI 52 including the upper housing 10A and the lower housing 10B. preferable. 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 UI 52 and the sub-panel 80 are distinguished from each other is that the power supply sources are different, which will be described in detail 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 circuit 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. Therefore, the main controller 18 individually supplies power to each processing unit (device) (power supply mode) or shuts off the power supply (sleep mode) to enable so-called partial power saving control.

  That is, the facsimile communication control circuit 16 in the image processing apparatus 10 must always monitor the reception state. On the other hand, the image reading unit 14 and the image forming unit 12 do not always have to be in a standby state as an operation mode, for example, if there is no instruction to execute a processing operation (service). Power consumption is reduced compared to continuing the operation mode. The operation state by partial power saving will be described later with reference to FIGS. 4 (A) and 4 (B).

  Further, the touch panel unit 40 of the UI 52 (see FIG. 2) is touched when the user is facing the UI 52 of the image processing apparatus 10, and when the user is not present in front of the image processing apparatus 10. The backlight (not shown) arranged on the back side of the touch panel unit 40 can be turned off.

  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.

  In addition, the sub panel 80 includes a display unit 88 that is operated under the control of the control unit 84 and operation keys 90 (in the present embodiment, for performing necessary minimum instructions such as adjustment of the display state on the display unit 88). Four independent operation keys 90A to 90D) are provided. In the present embodiment, display unit 88 receives power from power storage device 82 via power supply line 35 </ b> F, but display unit 88 may receive power from control unit 84.

  Note that the operation key 90 is not essential. In addition, 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, the display unit 88 has a backlight depending on the amount of power stored in the power storage device 82 or the power generation capability of the solar panel 86. 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).

  That is, the control unit 84 of the sub-panel 80 stores power coefficient values for each device (image reading unit 14, UI 52, main controller 18, and image forming unit 12) in advance, and the main controller 18 via the bus 33E. The power value is calculated on the basis of the operation information and the power coefficient value of each device received from. The display unit 88 displays a power value based on the calculation result.

  Here, every time the operation information is received from the main controller 18, the control unit 84 of the sub-panel 80 performs calculation and updates the power value displayed on the display unit 88.

  That is, in the main controller 18, when the power value is displayed on the display unit 88 of the sub-panel 80, the operation information is displayed on the sub-panel 80 each time the state (see the state A to the state C in FIG. 4) in the image processing apparatus 10 changes. To the control unit 84.

  On the other hand, in the present embodiment, the display of the power value is not limited to the display unit 88 of the sub-panel 80, but is displayed on the touch panel unit 40 of the UI 52 (see FIG. 2) according to the state in the image processing apparatus 10. There is a case.

  Specifically, when the state of the image processing apparatus 10 is the sleep mode or a state close thereto (state A to state C in FIG. 4), the power value is displayed on the display unit 88 of the sub-panel 80, and the image processing apparatus 10 When the state is the standby mode and the operation mode state (state D to state G in FIG. 4), the power value is displayed on the touch panel unit 40 of the UI 52.

  This selection switching of the power display contributes to securing the amount of power stored in the power storage device 88 of the sub-panel 80.

(Operation status and power display control by partial power saving control)
In the partial power saving control of the present embodiment, the power supply destination is selectively determined, and FIG. 4 shows the power supply state of each device according to the transition of the operation state of the image processing apparatus 10. In the following, the “operation state” is simply referred to as “state”, and the respective states are referred to as state A to state G.

  FIG. 4A and FIG. 4B express the arrangement of states A to G as similar shapes. In addition, as a legend of FIG. 4, a white base background indicates a power supply state, and a diagonal base background indicates a power non-supply state. Furthermore, as a legend in FIG. 4, there is a base background in which white and diagonal lines are mixed.

  In the case of the background of the base in which white and oblique lines are mixed, the power supply state is shown for some of them. That is, in the UI 52, the backlight of the touch panel unit 40 is turned off, but the operation instruction function is valid. Note that the operation instruction function may be disabled when the backlight of the touch panel unit 40 is off. The main controller 18 shows a state where functions other than the minimum necessary functions (facsimile reception monitoring, network communication, etc.) are stopped.

  Table 1 below shows the relationship between each state A to state G in FIGS. 4A and 4B, the presence or absence of power supply of each device, and the power value display target in the combination state. Has been.

  In the present embodiment, the functions of the image reading unit 14, the UI 52, the main controller 18, and most of the image forming unit 12 are stopped so that the power supply is stopped and the required minimum power consumption is achieved. May stop. This function stop may be referred to as “sleep mode (power saving mode)”.

  The sleep mode can be shifted, for example, by starting a system timer when image processing is completed. That is, the power supply is stopped when a predetermined time elapses after the system timer is started. If there is any operation (such as a touch operation on the touch panel unit 40 or an operation on the hard key 54 shown in FIG. 2) before the predetermined time elapses, the timer count to the sleep mode is naturally canceled and the next image is displayed. The system timer is restarted from the end of processing.

  Further, when starting up from the sleep mode, all devices are not supplied with power at the same time, and power supply is selectively executed based on the contents of processing operations (services) to be executed. In other words, a device that does not need to start up is kept in a non-power supply state (partial power saving function).

  By the way, the main controller 18 receives the minimum necessary power supply because, for example, in the monitoring in the sleep mode, for example, a print request comes from the communication line detection unit, or the FAX line detection unit sends a FAX. This is to respond to a reception request coming.

  If there is the above request (print request, FAX reception request), the job execution state is entered, and after all of the main controller 18 shifts to the power supply state, the device that is in the sleep mode becomes a device necessary for the job request. In contrast, power is supplied.

  Further, the sleep mode can be canceled by operating a power saving key 54D provided as a part of the hard key 54. Also in this case, first, after all of the main controller 18 has transitioned to the power supply state, power is supplied to devices required for the processing operation (service) among the devices in the sleep mode.

  The power saving key 54D is also operated when power is supplied to the device, thereby forcibly cutting off the power supply of the device and switching to the sleep mode.

  Further, as a trigger for canceling the sleep mode, not only the power saving key 54D but also a human sensor or the like is attached, a user approaching the image processing apparatus 10 is detected, the use of the image processing apparatus 10 is predicted, and the sleep mode is The mode may be canceled.

  As described above, even in the sleep mode in which power is not supplied, power is supplied that is equal to or lower than a predetermined power (for example, 1.5 w or lower) and that is necessary for determining whether to supply power. In this embodiment, in order to increase the user's interest in energy saving, a function of notifying the power consumption in the power supply state and the power non-supply state is provided. As a device for notifying power consumption, the touch panel unit 40 and the sub panel 80 of the UI 52 are used together.

  As shown in FIG. 5, the standard of power consumption in each of the states A to G shown in FIG. 4 changes within a certain range. That is, Aw is set in the standby state of the image reading device 14, Bw is set in the operating state, Cw is set in the standby state of the image forming unit 12, and Dw is set in the operating state. Thus, the current power consumption can be accurately predicted without actual measurement. Note that the power consumption may be significantly changed by changing the specification of the device (for example, the image forming unit 12), and is not limited to the power value shown in FIG. 5, but is shown as an example only.

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

  FIG. 7 is a flowchart showing a power value display control routine in the main controller 18.

  In step 100, it is determined whether or not there has been a change in the operating state. If a negative determination is made, this routine ends.

  Further, when an affirmative determination is made in step 100, the process proceeds to step 102, and an operation state confirmation process is executed. When the operation state is confirmed, the process proceeds to step 104 and the mode in the operation state confirmed. That is, it is determined whether it is waiting or being executed, and the process proceeds to step 106. For example, in the image forming unit 12, the power value during standby is about 100w to 110w, and during processing, there is a difference between 1200w and 1300w. Therefore, it is necessary to determine the operation state and each mode.

  In step 106, operation information is generated from the operation state and the mode in the operation state, and the process proceeds to step 108.

  In step 108, it is determined whether the transitioned operation state is any one of A, B, and C shown in FIG. 4 or any one of D, E, F, and G shown in FIG.

  If it is determined in step 108 that the transitioned operation state is any one of A, B, and C shown in FIG. 4, the process proceeds to step 109, and the sub-panel 80 is operated by remote operation from the main controller 18. Turn on and go to step 110. In step 110, it is determined whether the previous operation state is D, E, F, or G shown in FIG.

  If an affirmative determination is made in step 110, the power value is currently displayed on the touch panel unit 40 of the UI 52, so the process proceeds to step 112, the power value display is terminated, and the process proceeds to step 114. On the other hand, if a negative determination is made in step 110, the process proceeds to step 114.

  In step 114, operation information is sent to the control unit 84 of the sub-panel 80, and this routine ends.

  On the other hand, if it is determined in step 108 that the transitioned operating state is any one of D, E, F, and G shown in FIG. One of A, B, and C shown in FIG. 4 is determined.

  If an affirmative determination is made in step 116, the power value is currently displayed on the display unit 88 of the sub-panel 80. Therefore, the process proceeds to step 118, and the control unit 84 of the sub-panel 80 is instructed to end the power value display. Then, the process proceeds to step 119, the sub-panel 80 is turned off by remote control from the main controller 18, and the process proceeds to step 120. On the other hand, if a negative determination is made at step 116, the routine proceeds to step 120.

  In step 120, the power value is calculated based on the operation information, and then the process proceeds to step 122, where the power value is displayed on the touch panel unit 40 of the UI 52, and this routine ends.

  Note that step 109 may be a process of turning on the sub panel 80 when the UI 52 is turned off or the backlight of the touch panel unit 40 is turned off.

  FIG. 8 is a flowchart showing a power display control routine in the sub-panel 80.

  In step 150, it is determined whether operation information has been received from the main controller 18, and if a negative determination is made, the process proceeds to step 152 to determine whether a display end instruction has been received. If a negative determination is made in step 152, this routine ends.

  If an affirmative determination is made in step 150, the process proceeds to step 154, where the power value is calculated based on the received operation information, and then the process proceeds to step 156, where the power value is displayed on the display unit 88. This routine ends. During the period in which the power value is displayed on the display unit 88 of the sub-panel 80 in step 156, power is supplied to maintain the display state independently on the display unit 88 and power to the control unit 84 of the sub-panel 80 is supplied. The supply may be turned off. As a means for maintaining the display state independently in the display unit 88, for example, an IC including a memory for holding display information may be mounted on the display unit 88.

  On the other hand, when an affirmative determination is made at step 152, the routine proceeds to step 158, where the power value display on the display unit 88 of the sub-panel 80 is terminated, and this routine is terminated. Thereby, the power consumption in the display part 88 is also suppressed.

  Note that the display unit 88 may be an electronic paper that does not require power and can maintain the display state except when switching display contents.

  A more specific state transition and power value display of the image processing apparatus 10 in the present embodiment will be described with reference to FIGS.

  Note that FIG. 4B shows the state transition of the image processing apparatus 10 corresponding to FIG. 4A and is described specifically for the energized state of the sub panel 80 and the UI 52.

  As shown in FIGS. 4A and 4B, when a series of processing operations (services) are completed and a predetermined time has elapsed, the image processing apparatus 10 transitions to the sleep mode (state A).

  In this state A, the image reading unit 14, the UI 52, the main controller 18, and the image forming unit 12 are all in a non-power supply state in principle. However, since information that triggers execution of a job may be received from the outside (network communication network 20, telephone network 22), a part of the main controller 18 supplies power in preparation for reception from the outside. Therefore, about 1.5 w of power is consumed. Note that “degree” means to allow variation within a predetermined error range, and the same interpretation is applied to the following power value display. The allowable error may be a ratio (for example, 1.5 ± X%) or a numerical value (for example, 1.5 ± Yw).

  When in the state A, if there is a job execution instruction from the outside, the state transitions to the state B or the state C.

  The types of jobs in the state B include stored print, direct FAX transmission, FAX confidential reception, time designation FAX transmission, and confidential box extraction. In this state B, the image reading unit 14 is in a non-power supply state, the UI 52 is in a state in which the backlight of the touch panel unit 40 is turned off, the main controller 18 is in a power supply state in which all functions can operate, and the image forming unit 12 is in a non-power supply state. It becomes a supply state and power of about 10 w is consumed.

  On the other hand, the job types in the state C include printing, FAX reception printing, and time designation printing. In this state C, the image reading unit 14 is in a non-power supply state, the UI 52 is in a state in which the backlight of the touch panel unit 40 is turned off, the main controller 18 is in a power supply state in which all functions can operate, and the image forming unit 12 is in power supply. It becomes a state and power of about 80w to 1200w is consumed.

  Next, in the state A, if there is an operation of the power saving key 54D, the state transitions to the state D in order to accept a processing operation (service).

  In state D, the image reading unit 14 is in a non-power supply state, the UI 52 is in a power supply state in which all functions can operate, the main controller 18 is in a power supply state in which all functions can operate, and the image forming unit 12 is not in power supply. It becomes a state and power of about 30 w is consumed.

  In the state D, when the user operates the UI 52 to input an instruction, any one of the copying process, the image reading process, and the image forming process is selected and executed.

  When the user selects the copy process, the image processing apparatus 10 transitions from the state D to the state E.

  In the state E, all devices are in a power supply state, that is, the image reading unit 14 is in a power supply state, the UI 52 is in a power supply state in which all functions can operate, and the main controller 18 is in a power supply state in which all functions can operate. The image forming unit 12 is in a power supply state and consumes about 110 w to 1300 w of power.

  When the user selects the image reading process, the image processing apparatus 10 transitions from the state D to the state F.

  In state F, the image reading unit 14 is in a power supply state, the UI 52 is in a power supply state in which all functions can operate, the main controller 18 is in a power supply state in which all functions can operate, and the image forming unit 12 is in a power non-supply state. Thus, about 50 to 100 w of power is consumed.

  When the user selects the image forming process, the image processing apparatus 10 transitions from the state D to the state G.

  In the state G, the image reading unit 14 is in a non-power supply state, the UI 52 is in a power supply state in which all functions can operate, the main controller 18 is in a power supply state in which all functions can operate, and the image forming unit 12 is in a power supply state. Thus, about 100 to 1220 w of power is consumed.

  As described above, in the image processing apparatus 10 according to the present embodiment, unnecessary power consumption is suppressed by the partial power saving control.

  On the other hand, the image processing apparatus 10 transitions to various states depending on the combination of the power supply state and the power non-supply state of each device, and the power consumption differs in each state. You may not be able to figure out. In particular, when recognizing how much power is consumed in the sleep mode, the power may be consumed by monitoring the power or displaying the power value on the touch panel unit 40 of the UI 52 itself.

  Therefore, in this embodiment, the touch panel unit 40 of the UI 52 and the sub-panel 80 having an independent power storage function are used in combination, and the power in each state (state A to state G shown in FIG. 4) in the image processing apparatus 10. The value was reported (displayed).

  The main controller 18 is partially supplied with power even in the sleep mode. The control system to which the power is supplied recognizes the state of the image processing apparatus 10 and uses the sub panel via the bus 33E as operation information. It transmits to the control part 84 of 80 as needed.

  Here, in the present embodiment, the above-mentioned “transmission as needed” means that the power value is displayed as either the display unit 88 of the sub-panel 80 or the touch panel unit 40 of the UI 52, and image processing. Since it is selectively determined according to the state of the device 10 (state A to state G), the transmission of the operation information to the sub-panel 80 means that whether or not it can be executed is determined according to the state.

  In addition, since transmission of the operation information from the main controller 18 does not affect the power consumed, the main controller 18 transmits the operation information in all states, and on the control unit 84 side of the sub panel 80, You may make it choose.

  When the state of the image processing apparatus 10 is any one of state A, state B, and state C, the power value is displayed on the display unit 88 of the sub-panel 80. Therefore, the operation information is sent from the main controller 18 to the control unit 84 of the sub panel 80 via the bus 33E.

  The control unit 84 of the sub panel 80 calculates the power value based on the power coefficient stored in advance based on the received operation information. More specifically, the operation information includes execution information (standby / processing) of each device in addition to the states (state A to state G), and a guideline according to the state (see FIG. 5). ) Is determined based on the execution information, and displayed on the display unit 88 as shown in FIGS. 6 (A) to 6 (C).

  FIG. 6B shows a case where the image processing apparatus 10 is in the state B, where a power display value (here, “10w”) is displayed on the display unit 88 of the sub-panel 80, and the touch panel unit 40 of the UI 52 is in a non-power supply state. Alternatively, the backlight is off (see state B in FIG. 4B).

  FIG. 6C shows a case where the image processing apparatus 10 is in the state C. The power display value (here, “1200w”) is displayed on the display unit 88 of the sub-panel 80, and the touch panel unit 40 of the UI 52 is in a power non-supply state. Alternatively, the backlight is off (see state C in FIG. 4B).

  On the other hand, when the state of the image processing apparatus 10 is any one of state D, state E, state F, and state G, the power value is displayed on the touch panel unit 40 of the UI 52. Accordingly, the operation information is not sent from the main controller 18 to the sub panel 80.

  The main controller 18 calculates the power value based on the power coefficient stored in advance based on the operation information. More specifically, the operation information includes execution information (standby / processing) of each device in addition to the states (state A to state G), and a guideline according to the state (see FIG. 5). ) To determine the power value based on the execution information and display it on the touch panel unit 40 as shown in FIGS. 6 (D) to 6 (G). In this case, since the display unit 88 of the sub-panel 80 is in a non-display state and the control unit 84 does not perform operations such as arithmetic processing, the power value is displayed on the display unit 88 of the sub-panel 80 even in the state D to the state G. In addition, the power consumption of the power storage device 82 is reduced.

  FIG. 6D shows the case where the image processing apparatus 10 is in the state D. The power display value (here, “30w”) is displayed on the touch panel unit 40 of the UI 52, and nothing is displayed on the display unit 88 of the sub-panel 80. (Refer to state D in FIG. 4B).

  FIG. 6E shows the case where the image processing apparatus 10 is in the state E. The power display value (here, “1300w”) is displayed on the touch panel unit 40 of the UI 52, and nothing is displayed on the display unit 88 of the sub-panel 80. (See state E in FIG. 4B).

  FIG. 6F shows a case where the image processing apparatus 10 is in the state F. A power display value (here, “100w”) is displayed on the touch panel unit 40 of the UI 52, and nothing is displayed on the display unit 88 of the sub-panel 80. (Refer to state F in FIG. 4B).
