Abstract:
1. A power supply control apparatus comprising: a plurality of processing units configured to be activated when power is supplied from a power supply unit to execute a predetermined process; a mobile body detection unit that detects a mobile body including a user who uses a processing unit from among the plurality of processing units based on a position of the processing unit; a determination unit that determines a presence or an absence of the mobile body confronting the processing unit based on a signal output from the mobile body detection unit; a transition unit that controls the processing unit to transition to a powered-on state in which the processing unit receives power from the power supply unit when the determination unit determines that the mobile body is present and to a powered-off state in which the processing unit does not receive power from the power supply unit when the determination unit determines that the mobile body is absent; a mobile body confirmation unit that confirms the presence or the absence of the mobile body from the mobile body detection unit when a request for transition from the powered-on state to the powered-off state for the transition unit is received; and a controller that controls the transition unit such that all of the processing units transition to the powered-off state when a result of confirmation in the mobile body confirmation unit indicates the absence of the mobile body and controls the transition unit such that the states of the plurality of processing units selectively and individually transition to the powered-off state when the result of the confirmation in the mobile body confirmation unit indicates the presence of the mobile body.
