Patent ID: 8773719

Claim:
A power supply control device, comprising: a load that executes a predetermined process and operates when power is supplied from a power supply unit; a power supply state transition controlling unit that allows at least the load to be transitioned to a power supply state in which power is supplied from the power supply unit, or a power interruption state in which power is not supplied from the power supply unit; a plurality of detection units that can operate within respective power-consumption ranges that are set in a stepwise manner, and detects information related to the execution of the load; a power supply control unit for detection unit, which supplies power continuously with respect to a minimum power-consumption type detection unit that operates with the smallest power-consumption among the plurality of detection units, and which supplies power to a detection unit having a relatively large power-consumption based on a detection result of a detection unit having a relatively small power-consumption among the plurality of detection units; and a transition time determining unit that is executed when power is supplied with respect to a maximum power-consumption type detection unit operating with the largest power-consumption, among the plurality of detection units, through a stepwise power supply control performed by the power supply control unit for the detection units, and that determines a transition time by the power supply state transition controlling unit based on the detection result from the maximum power-consumption type detection unit.
