According to one embodiment, a semiconductor device includes a fin type stacked layer structure which has first to third semiconductor layers, and first to third layer select transistors to select one of the first to third semiconductor layers. The material forms a coating or bandage in the form of a film when applied to a surface or the skin of a user. Two pawls are pivotally supported by the handle adjacent the gear and are orbital about the axis upon rotation of the handle. A first arm mounting portion to which the first end portion is affixed and second arm mounting portions to which the second end portion is affixed are provided to a holder.
