Abstract
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.
