<p>PROBLEM TO BE SOLVED: To efficiently perform power control according to environmental light at a low cost.SOLUTION: A power source control device 1 is connected to an apparatus that operates by electric power, and a solar battery 2 receives environmental light to generate power. In the power source control device 1, a comparator 6 operates by the electric power generated by the solar battery 2, and detects light quantity of the environmental light based on the amount of generated electric power. Further, in the power source control device 1, a pulse generation circuit 9 operates by the electric power generated by the solar battery 2, acquires an operation signal Sc representing power state of an apparatus to be controlled from the apparatus, and, based on the operation signal Sc and the light quantity of the environmental light detected by the comparator 6, outputs a power source control signal Sg indicating power state of the apparatus.</p> |
