Abstract
An opening and closing portion is opened and closed. A switch is turned off when a voltage applied to a drive terminal is smaller than a first voltage and to be turned on when the voltage is greater than or equal to a second voltage. A drive unit generates a drive voltage. A first line applies the drive voltage to the switch. A second line is arranged such that at least a part thereof is near the first line. A voltage drop element provided on the first line drops a voltage applied from the second line through the first line to the drive terminal when the first line and the second line short-circuit in a state where the portion is open, to lower the voltage applied to the drive terminal to be smaller than the first voltage.
