SOLUTION: An automatic power source cutoff device includes a first determination part for determining whether or not someone is at home, a second determination part for determining whether or not a value expressing a scale of an earthquake is larger than a prescribed value by obtaining information about occurrence of the earthquake, a clocking part for clocking a time, a third determination part for determining whether or not an occurrence time of the earthquake obtained from the clocked time of the clocking part is a time in a time zone set in advance, and a control part for making an indoor lighting system capable of lighting in a fixed time and cutting off a power source in a distribution panel after the fixed time passed, when the first determination part determines that someone is at home, the second determination part determines that the value expressing the scale of the earthquake is larger than the prescribed value, and the third determination part determines that the occurrence time of the earthquake is in the time zone mentioned above.SELECTED DRAWING: Figure 1 |
