POWER SUPPLY CONTROL APPARATUS, IMAGE PROCESSING APPARATUS, POWER SUPPLY CONTROL METHOD, AND RECORDING MEDIUM STORING A POWER SUPPLY CONTROL PROGRAM

摘要

A novel power supply control device includes an external power supply unit that generates external driving power from external power source, a storing power supplying unit that generates stored driving power from stored power source, a selection unit that selects either the external driving power or the stored driving power, a power mode switching unit that switches between a normal mode and an energy saving mode that consumes less power consumption than the normal mode, a determination unit that determines whether or not current time is within a peak power shift time zone in which usage of the external power is suppressed, and a controlling unit that instructs the selection unit to select the stored power as the driving power and instructs the power mode switching unit to switch power mode to the energy saving mode immediately after finishing an operation during the power peak shift time zone.

1. A power supply control device, comprising:
an external power supply unit to generate external driving power to be supplied to an image processing apparatus from external power source; a storing power supplying unit to generate stored driving power to be supplied to the image processing apparatus from stored power source; a selection unit to select either the external driving power or the stored driving power as driving power supplied to the image processing apparatus; a power mode switching unit to switch power mode of the image processing apparatus between a normal mode and an energy saving mode, the energy saving mode consuming less power consumption than power consumption for the normal mode; a determination unit to determine whether or not current time is within a peak power shift time zone in which usage of the external power is suppressed, and further determine whether the image processing apparatus is performing an operation; and a controlling unit to instruct the selection unit to select the stored power as the driving power when the determination unit determines that the current time is within the peak power shift time zone, and further instruct the power mode switching unit to switch power mode of the image processing apparatus to the energy saving mode immediately after the image processing apparatus ends the operation being performed during the power peak shift time zone.
