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

摘要

A power-supply control device includes a power-supply-state transition control section, body-capable-of-movement detection sections, and an instruction 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 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.

1. A power-supply control device comprising:
a power-supply-state transition control section that shifts a state of an operation target section from one state to another state among a plurality of power-supply states and a non-power supply-state, the operation target section being a section which operates by receiving supply of power from a mains power source section, each of the plurality of power-supply states being a state having a power consumption which is a corresponding one of power consumptions that are different from one another, the non-power-supply state being a state in which supply of power is not received from the mains power source section or a state in which supply of power that is lower than power determined in advance and that is necessary for control of determining whether or not power is to be supplied is received from the mains power source section; a plurality of body-detection sections that detect a body in a region which is set in advance, each of the plurality of body detection sections having a corresponding one of detection conditions different from one another, the body including a user who intends to use the operation target section, one of the plurality of body-detection sections continuously receiving supply of power as a section used for determination control in the non-power-supply state, another one of the plurality of body-detection sections receiving supply of power as the section used for determination control in response to when the body is detected by the body-detection section that continuously receives supply of power in the non-power-supply state; and an instruction section that provides, on the basis of a detection state, an instruction for shifting the state of the operating target section from one state to another state which the power-supply-state transition control section the detection section that receives supply of power in response to when the body is detected by the body-detection section that continuously receives supply of power in the non-power-supply state, wherein when a body is not detected but a job of an operating target section is still executing determining a type of job being performed and placing one or more unused operating target section, based on the type of job being performed, in a non-power-supply state, and when a predetermined amount of time has passed since old jobs have finished executing placing all operating target sections of the multi-functional printer into a non-power-supply state.
