Abstract

An actuator has a driving first coil and a driving second coil. A capacitor is electrically connected to both the first coil and the second coil through a discharge switch using electric power accumulated in a capacitor which can be selectively supplied. An operation portion for operating the discharge switch is electrically connected to the discharge switch. For example, when an electric power supplied to the operation portion is cut due to a power failure, the second coil and the capacitor are electrically connected to each other through the discharge switch.
