A power-supply control device includes a power-supply-state transition control section, body-capable-of-movement detection sections, a time measuring section, a transition-instruction section, and an instruction-provision-time postponement section. The power-supply-state transition control section shifts a state of an operation target section from one state to another state among power-supply states and a non-power-supply state. The body-capable-of-movement detection sections detect a body capable of movement in a region. The time measuring section measures a time over which the operation target section in one of the power-supply states is not used. The transition-instruction section provides, for the power-supply-state transition control section, an instruction for shifting to the non-power-supply state. The instruction-provision-time postponement section postpones an instruction-provision time at which the instruction is provided by the transition-instruction section.

Power-supply control device, image processing apparatus, power-supply control method, and computer readable medium

A power-supply control device includes a power-supply control section, a first detection section that detects whether or not a body capable of movement is moving, a second detection section that detects whether or not the body capable of movement exists, and an instruction section. The power-supply control section receives supply of power from a mains power source section, and selectively sets a power supply mode, in which power is supplied to a processing section, and a power saving mode, in which supply of power to the processing section is stopped. The first and second detection sections and the instruction section are caused to operate at least in the power saving mode. The instruction section provides, for the power-supply control section, an instruction for switching between the power supply mode and the power saving mode.

The body-capable-of-movement detection sections detect a body capable of movement in a region. The instruction section provides, on the basis of results of detection of the body capable of movement by the body-capable-of-movement detection sections, at least an instruction for shifting between one of the power-supply states and the non-power-supply state, among instructions for shifting the state of the operation target section from one state to another state with the power-supply-state transition control section.

Power-supply control device for shifting the operating state of a multi-functional printer depending on the detection of a body in a predetermined region

A power supply control device including a mode switching controller, a first power supply section, a second power supply section, a third power supply section, a wiring system opening and closing unit and a controller. During the sleep mode, the first power supply section continues to supply power to a specific control system, the second power supply section shuts off its supply of power, and the third power supply section supplies power to the specific control system by a separate system to the specific control system. The wiring system opening/closing unit sets a power supply wiring system of the commercial power source to an open state or a closed state. When the third power supply section is supplying power during the sleep mode, the controller controls the wiring system opening and closing unit and sets the power supply wiring system of the commercial power supply to the open state.

Power supply control device, image processing device, power supply control method, and computer readable medium

A power supply control device includes a power supply controller that selectively performs a power supply mode and a power saving mode, a detector that detects a moving body in a predetermined range in the vicinity of the processor, a power supply mode change instruction unit that changes an operation mode from the power saving mode to the power supply mode when the detector detects the moving body, an information history unit that acquires information related to an operation for the processor in the power supply mode, and a sensitivity adjusting unit that adjusts a detection sensitivity of the detector for the moving body on the basis of the information acquired by the information history unit for a period from a change of the operation mode from the power saving mode to the power supply mode to a change of the operation mode to a next power saving mode.
