PROBLEM TO BE SOLVED: To detect a change of a switch by suppressing increase of a cost and power consumption, even in an energy saving mode being less power consumption.SOLUTION: A state detection device includes a switch which displaces between a first position and a second position that is different from the first position, an energy accumulation means which is connected with the switch via a signal line and discharges electric charges that has been accumulated when the switch displaces from the second position to the first position, a detection means that detects a state of the energy accumulation means during a second mode whose power consumption is less than the first mode, and a control means which determines a change of a position of the switch according to a result detected by the detection means. |
