Description

The invention according to claim 1, in order to perform the processing of a plurality kinds of predetermined plural loads alone, or two or more work together, as a target at least the plurality of loads, power unit Power supply state transition control means for making a transition to a power supply state that receives power from the power supply, or a power cut-off state that does not receive power supply from the power supply unit, and power is always supplied even when the load is in a power cut-off state. A first detection means capable of detecting a moving body approaching the load, and a power cut-off state together with the load, and when the mobile body is detected by the first detection means in the power cut-off state, electric power is generated. A second detection unit that is supplied and activated to detect the moving body; a determination unit that determines an operation mode of the moving body based on detection information detected by the second detection unit; Power supply control means for selectively controlling the supply of power to the load necessary for executing the processing specified based on information relating to the operation mode of the moving object determined by means. ing.

The invention according to claim 7 is the invention according to any one of claims 1 to 6, wherein the load operates by receiving power supply and executes a predetermined process. The mode is classified into a processing unit and an instruction unit that selectively instructs at least the contents of the processing to the plurality of processing units, and the first detection unit and the second are set as modes in which transition is performed in the power cutoff state . A sleep mode including an awake state in which power is supplied to a monitoring control unit for analyzing a detection result by the detection unit or power is supplied to the instruction unit as necessary, and transition is made in the power supply state. As a mode, a warm-up mode, which is a preparation stage for starting up the processing unit from the sleep mode, and a standby mode in which power is supplied to the processing unit at a lower level than normal Comprising a plurality of modes including a running mode for supplying the power during the steady relative to the processing unit, it shifts the mode according to the situation of the processing.

Claims (9)
