(Embodiment 1)
[Hardware configuration]
A hardware configuration of the image processing apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating a hardware configuration example of the image processing apparatus according to the first embodiment.

  As illustrated in FIG. 1, the image processing apparatus 100 includes a power supply unit 10 and a system unit 20. Among these, the power supply unit 10 includes an AC / DC conversion unit 11, a battery 12, a power management unit 13, and a DC / DC conversion unit 14. The power supply unit 10 executes processing related to the power supply of the image processing apparatus 100. The system unit 20 includes a controller 21, a scanner 22, a plotter 23, and an operation display unit 24. The system unit 20 executes processes related to various image processes of the image processing apparatus 100.

The AC / DC conversion unit 11 converts an AC voltage input from an AC power source, which is a commercial AC power source, into a predetermined DC voltage. Such an AC power source supplies power as a main power source. In FIG. 1, an arrow input to the AC / DC converter 11 represents an input from an AC power source. For example, the DC power output from the AC / DC converter 11 is “V ₁ ”.

The battery 12 is a storage battery having a DC-DC conversion function for charging and discharging. The battery 12 supplies power as an auxiliary power source for the main power source. For example, when the battery 12 is used as an auxiliary power source, the DC power source for discharge output by the battery 12 is “V ₂ ”.

The power management unit 13 has a function of detecting the stop of the AC power supply due to a power failure, a function of detecting the remaining amount of the battery 12, and “V ₁ ” as the power supply “V ₃ ” output to the DC / DC conversion unit 14. It has a function of switching between “V ₂ ” and a function of communicating with the controller 21. For example, the power management unit 13 detects that a power failure has occurred based on the DC power source “V ₁ ” output by the AC / DC conversion unit 11. When the power management unit 13 detects that a power failure has occurred, the power management unit 13 changes the power source “V ₃ ” output to the DC / DC conversion unit 14 from the DC power source “V ₁ ” of the main power source to the DC power source of the auxiliary power source. Switch to “V ₂ ”. Thereafter, the power management unit 13 notifies the controller 21 of information indicating that a power failure has occurred and information indicating that the main power source has been switched to the auxiliary power source. The power management unit 13 detects the remaining amount of the battery 12 and notifies the controller 21 of information related to the detected remaining amount.

The DC / DC conversion unit 14 converts the power source “V ₃ ” output by the power management unit 13 into a logic power source “V ₄ ” or a power power source “V ₅ ” used by the system unit 20. Then, the DC / DC converter 14 outputs the logic power supply “V ₄ ” and the power power supply “V ₅ ” to the system unit 20.

  The controller 21 performs overall control of the image processing apparatus 100. For example, the controller 21 has a function of communicating with the power management unit 13 and a function of calculating the number of copies and the number of prints that can be processed by execution of image processing by the image processing apparatus 100 based on information on the remaining amount of the battery 12. Have That is, the controller 21 receives information related to the remaining amount of the battery 12 from the power management unit 13 and calculates the number of copies and prints that can be processed with the remaining amount of the battery 12.

  The scanner 22 optically reads a document and generates image data. The plotter 23 prints (prints) on paper or the like based on the image data. The operation display unit 24 displays various information and accepts various inputs by user operations. For example, the operation display unit 24 displays the processing status of image processing performed by the image processing apparatus 100, the number of copies that can be processed, the number of copies printed, and the like calculated by the controller 21. In addition, for example, the operation display unit 24 receives input such as start of image processing by user operation and various settings related to image processing.

  That is, when switching to power supply from the battery 12 serving as an auxiliary power source, the image processing apparatus 100 calculates the number of copies and prints that can be processed with the remaining amount of the battery 12 and displays it on the operation display unit 24. . As a result, the image processing apparatus 100 can grasp to what extent the auxiliary power supply can be used.

  Further, the image processing apparatus 100 is not limited to the configuration shown in FIG. For example, the image processing apparatus 100 may be a multifunction machine having at least two functions among a printing function, a copying function, a scanner function, and a facsimile function. Detailed functions of the image processing apparatus 100 will be described later.

[Functional configuration according to Embodiment 1]
Next, the functional configuration of the image processing apparatus 100 according to Embodiment 1 will be described with reference to FIG. FIG. 2 is a block diagram illustrating a functional configuration example of the image processing apparatus 100 according to the first embodiment.

  As shown in FIG. 2, the image processing apparatus 100 includes a state detection unit 110, a power control unit 120, a remaining amount detection unit 130, a power consumption storage unit 140, a calculation unit 150, a discharge depth change unit 160, And an output unit 170. Among these, the state detection unit 110, the power supply control unit 120, the remaining amount detection unit 130, and the discharge depth change unit 160 are examples of functions mainly included in the power management unit 13. The power consumption storage unit 140, the calculation unit 150, and the output unit 170 are examples of functions mainly included in the controller 21. In addition, about each said part, all or some of these may be implement | achieved by software (program), and may be implement | achieved by the hardware circuit.

  The state detection unit 110 detects the state of power supply from the main power source. More specifically, the state detection unit 110 detects the state of power supply from the main power supply from the output state of the DC power supply by the AC / DC conversion unit 11 that has received an input from the AC power supply that is the main power supply. For example, the state detection unit 110 detects the state as if power is being supplied from the main power supply when the output status of the DC power supply is output as usual. On the other hand, when the output state of the DC power supply is stopped, the state detection unit 110 detects the state as if power is not supplied from the main power supply. In addition, when the state detection unit 110 detects a state in which power supply from the main power source is not performed and then becomes possible to output from the DC power source, power supply from the main power source can be started. Also detect.

  Here, the state where the power supply from the main power source is not performed can occur mainly in the following two situations. The first is, for example, a case where a power failure occurs due to some factor. The second case is, for example, a case where an operation for switching the power supply source from the main power source to the auxiliary power source is performed by the user. Such an operation is performed using the operation display unit 24.

  FIG. 3 is a diagram illustrating an example of the operation display unit 24 according to the first embodiment. As shown in FIG. 3, the operation display unit 24 includes a display unit 24a, a numeric keypad 24b, a stop button 24c, a start button 24d, a backup key 24e, and a discharge control key 24f.

  The display unit 24a is a display that displays various screens. Such a display may be a touch panel display. The numeric keypad 24b includes numeric keys and arrow keys for performing various settings. The stop button 24c is a button for stopping a process being executed in the image processing apparatus 100. The start button 24d is a button for causing the image processing apparatus 100 to start execution of processing and the like.

  The backup key 24e is a button for switching the power supply source. When the backup key 24e is pressed, the controller 21 notifies the power management unit 13 of information indicating that the backup key 24e is pressed. The user operates the backup key 24e based on information representing the state of power supply from the main power source displayed on the display unit 24a. For example, when the backup key 24e is pressed while power is being supplied from the main power supply, the power supply is switched from the auxiliary power supply. Further, when the backup key 24e is pressed in a state where power is supplied from the auxiliary power supply, the power supply is switched from the main power supply.

  The discharge control key 24f is a button for changing the depth of discharge of the battery 12, which is an auxiliary power source. In general, it is preferable that the battery is controlled so as to avoid deep discharge in order to suppress deterioration and to cut discharge while leaving a certain amount of capacity. However, in an emergency such as a power failure, there is a need to increase the number of printed sheets even if the battery is deteriorated. For this reason, the discharge control key 24f is used to increase the depth of discharge of the battery 12 in a situation where power is supplied from the battery 12 as the auxiliary power source due to a power failure or the like.

  Returning to the description of FIG. 2, the power supply control unit 120 performs control to switch between power supply from the main power supply and power supply from the auxiliary power supply. More specifically, the power supply control unit 120 determines that the battery 12 that is an auxiliary power supply from the power supply from the main power supply when the state detection unit 110 detects the stop of the power supply from the main power supply due to a power failure or the like. Control to switch to power supply from. On the other hand, the power supply control unit 120 starts from the power supply from the battery 12 as the auxiliary power supply when the state detection unit 110 detects that the power supply from the main power supply can be resumed due to recovery from a power failure or the like. Control to switch to power supply from the main power source is performed.

  In addition, when the power supply from the main power supply is performed, the power supply control unit 120 starts the battery supply as an auxiliary power supply from the power supply from the main power supply when a user operation to press the backup key 24e is performed. Control to switch to power supply from 12 is performed. On the other hand, when power is supplied from the auxiliary power supply, the power supply control unit 120 starts from the power supply from the battery 12 serving as the auxiliary power supply when a user operation to press the backup key 24e is performed. Control to switch to power supply from the power supply is performed.

  The remaining amount detection unit 130 detects the remaining amount of auxiliary power. More specifically, the remaining amount detection unit 130 detects the remaining amount of the battery 12 serving as an auxiliary power source at predetermined intervals or at arbitrary timing. The process for detecting the remaining amount of the battery 12 may be executed every predetermined period, for example, triggered by switching of the power supply from the main power supply to the auxiliary power supply. Or the process which detects the residual amount of the battery 12 should just be performed according to the change of the depth of discharge mentioned later by using as a trigger that the electric power supply was switched from the main power supply to the auxiliary power supply, for example. Then, the remaining amount detecting unit 130 outputs the detected remaining amount of the battery 12 to the calculating unit 150.

  The power consumption storage unit 140 stores power consumption when image processing is performed for a predetermined number of sheets. For example, the power consumption storage unit 140 stores power consumption due to printing processing and copying processing per sheet. That is, the power consumption storage unit 140 stores power consumption when a predetermined number of sheets is processed by the image processing apparatus 100 for each function such as print processing and copy processing.

  The calculation unit 150 calculates the number of sheets that can be processed by executing image processing based on the remaining amount of auxiliary power. More specifically, calculation unit 150 receives the remaining amount of battery 12 output by remaining amount detection unit 130. In addition, when the remaining amount of the battery 12 is received from the remaining amount detecting unit 130, the calculating unit 150 calculates the power consumed by the image processing per sheet for each function such as the printing process and the copy process, and the power consumption storage unit 140. Get from. Then, the calculation unit 150 determines the number of sheets that can be processed by executing each function of the image processing from the remaining amount of the battery 12 and the power consumption of the image processing per sheet corresponding to each function such as the printing process and the copying process. Is calculated. In the following, the number of sheets that can be processed by executing each function of image processing such as print processing and copy processing may be referred to as “number of sheets that can be processed”.

  The power consumed by image processing per sheet used for calculating the number of sheets that can be processed varies depending on the size of the paper used and the accuracy of image processing. Therefore, for example, the power consumption may be a value when image processing is executed on A4 paper.

  The discharge depth changing unit 160 changes the discharge depth of the auxiliary power supply. More specifically, the discharge depth changing unit 160 deepens the discharge depth of the battery 12 serving as an auxiliary power source when the number of processable sheets calculated by the calculation unit 150 is equal to or less than a predetermined threshold. That is, the discharge depth changing unit 160 increases the processable number of sheets by increasing the depth of discharge of the battery 12 when the number of processable sheets decreases in a situation where the battery 12 as an auxiliary power source is used. . In addition, you may set a limit to the depth of the set discharge depth.

  In addition to the above, the discharge depth changing unit 160 executes a process of deepening the discharge depth of the battery 12 serving as an auxiliary power source, triggered by pressing of the discharge control key 24f. That is, the discharge depth changing unit 160 increases the discharge depth of the battery 12 when a user operation for pressing the discharge control key 24f is performed in a situation where the battery 12 as an auxiliary power source is used. Increase the number of sheets that can be processed.

  The output unit 170 outputs the state of power supply from the main power supply, the number of processable sheets, the discharge depth of the auxiliary power supply, and the like. More specifically, the output unit 170 outputs the state of power supply from the main power source detected by the state detection unit 110 to the operation display unit 24. As a result, the operation display unit 24 displays information indicating that power is being supplied from the main power supply on the display unit 24a. The user can perform a user operation of pressing the backup key 24e based on the state of power supply from the main power source displayed on the display unit 24a.

  Further, the output unit 170 outputs the processable number calculated by the calculation unit 150 and the discharge depth of the battery 12 serving as an auxiliary power source to the operation display unit 24. Thereby, the operation display unit 24 displays information such as the number of processable sheets and the depth of discharge of the battery 12 on the display unit 24a. By displaying information on the number of processable sheets on the display unit 24a, the user can grasp the extent to which the auxiliary power supply can be used.

  A screen displayed on the display unit 24a will be described with reference to FIGS. 4A to 4D. FIG. 4A is a diagram illustrating an example of a display screen during printing when power is supplied from the main power source. FIG. 4B is a diagram illustrating an example of a display screen during printing when power is supplied from the auxiliary power source. FIG. 4C is a diagram illustrating an example of a display screen updated as time elapses during printing when power is supplied from the auxiliary power source. FIG. 4D is a diagram illustrating an example of a display screen updated by changing the depth of discharge during printing when power is supplied from the auxiliary power source.

  As shown in FIG. 4A, when printing is performed by printing processing, copying processing, or the like when power is supplied from the main power supply, information indicating that printing is in progress is displayed on the display unit 24a. Although not shown in FIG. 4A, the state of power supply from the main power supply may also be displayed on the display unit 24a.

  As shown in FIG. 4B, when printing is performed by printing processing, copying processing, or the like when power is supplied from the auxiliary power source, information indicating that backup printing is being performed using the battery 12 as the auxiliary power source (backup power source). Is displayed on the display unit 24a. In addition, as shown in FIG. 4B, information such as the number of printable sheets (for example, “100”), the number of copyable sheets (for example, “50”), the discharge depth of the battery 12 (for example, “80%”), and the like are also displayed on the display unit 24a. Is displayed.

  When time elapses from the state shown in FIG. 4B, information on the number of printable sheets and the number of copyable sheets is updated. For example, as shown in FIG. 4C, the number of printable sheets is updated from “100” to “50”, and the number of copyable sheets is updated from “50” to “25”. That is, the remaining amount of the battery 12 decreases with time, and the number of printable sheets and the number of copyable sheets decrease.

  When the discharge control key 24f is pressed in the state shown in FIG. 4C, the information on the discharge depth of the battery 12 is updated. In addition, as the discharge depth of the battery 12 is changed, information on the number of printable sheets and the number of copyable sheets is also updated. For example, as shown in FIG. 4D, the discharge depth is updated from “80%” to “50%”, the number of printable sheets is updated from “50” to “80”, and the number of copyable sheets is changed from “25”. It is updated to “40”.

  When the processable number of sheets shown in FIG. 4C is equal to or less than a predetermined threshold, the information on the discharge depth of the battery 12 is updated. In addition, as the discharge depth of the battery 12 is changed, information on the number of printable sheets and the number of copyable sheets is also updated. For example, as shown in FIG. 4D, the discharge depth is updated from “80%” to “50%”, the number of printable sheets is updated from “50” to “80”, and the number of copyable sheets is changed from “25”. It is updated to “40”. That is, the discharge depth cut by “80%” by default is allowed up to “50%”. Then, the number of printable sheets and the number of copyable sheets are increased by changing the discharge depth.

[Overall Processing Flow According to Embodiment 1]
Next, the overall processing flow according to the first embodiment will be described with reference to FIG. FIG. 5 is a flowchart illustrating an example of the flow of overall processing according to the first embodiment. FIG. 5 shows an example in which processing is started in a normal state where power is supplied from the main power source.

  As shown in FIG. 5, when the state detection unit 110 detects the stop of the power supply from the main power supply (step S101: Yes), the power supply control unit 120 uses the auxiliary power supply from the power supply from the main power supply. Switching to power supply from a certain battery 12 (step S102). On the other hand, when the state detection unit 110 does not detect the stop of the power supply from the main power supply (step S101: No), the state detection unit 110 executes the process in step S101 again.

  The remaining amount detection unit 130 detects the remaining amount of the battery 12 that is an auxiliary power supply (step S103). The calculation unit 150 acquires the power consumption of the image processing per sheet from the power consumption storage unit 140, and performs image processing based on the remaining amount of the battery 12 detected by the remaining amount detection unit 130 and the acquired power consumption. The number of sheets that can be processed in the execution of each function is calculated (step S104).

  The discharge depth changing unit 160 determines whether or not the number of processable sheets calculated by the calculation unit 150 is equal to or less than a predetermined threshold (step S105). At this time, if the discharge depth changing unit 160 determines that the number of processable sheets is equal to or smaller than the predetermined threshold (step S105: Yes), the discharge depth changing unit 160 increases the discharge depth of the battery 12 as the auxiliary power source (step S106). On the other hand, when the discharge depth changing unit 160 determines that the number of processable sheets is larger than the predetermined threshold (step S105: No), the process in step S107 is performed without changing the discharge depth of the battery 12 as the auxiliary power source. Is executed.

  The output unit 170 outputs the processable number calculated by the calculation unit 150 and the discharge depth of the battery 12 serving as an auxiliary power source to the operation display unit 24. Thereby, the display unit 24a displays the processable number of sheets and the depth of discharge output by the output unit 170 (step S107). When the state detection unit 110 detects that the power supply from the main power supply can be resumed (step S108: Yes), the power supply control unit 120 starts from the power supply from the battery 12 as the auxiliary power supply. Switching to power supply from the main power supply (step S109). After switching to power supply from the main power supply, the process in step S101 is executed again.

  On the other hand, when it is not detected by the state detection unit 110 that the power supply from the main power supply can be resumed (step S108: No), the process in step S103 is executed again. In other words, the depth of discharge is set deeper if the number of sheets that can be processed falls below a predetermined threshold due to a decrease in the remaining amount of the battery 12 over time before the power supply from the main power supply can be resumed.

[Effects of Embodiment 1]
When the power supply from the main power supply is switched to the power supply from the auxiliary power supply, the image processing apparatus 100 detects the remaining amount of the auxiliary power supply and calculates the number of images that can be processed by image processing based on the detected remaining power. Then, the calculated number of processable sheets is output. As a result, the image processing apparatus 100 can make the user know how much the auxiliary power supply can be used. Further, when the auxiliary power source is used at the time of a power failure or the like, the image processing apparatus 100 can grasp the number of images that can be processed by the image processing. Can be improved.

  The image processing apparatus 100 switches from power supply from the main power supply to power supply from the auxiliary power supply by pressing the backup key 24e, and outputs the number of images that can be processed by image processing. As a result, the image processing apparatus 100 can arbitrarily realize a peak cut that keeps the peak of power demand low and a peak shift that shifts a time zone in which the power demand is maximized.

  Further, the image processing apparatus 100 increases the depth of discharge of the battery 12 serving as the auxiliary power source when the discharge control key 24f is pressed or when the number of processable sheets becomes a predetermined threshold value or less. As a result, the image processing apparatus 100 can increase the number of images that can be processed by image processing in the event of an emergency such as a power failure, thereby improving convenience.
