A capacitance type sensor includes a substrate, a group of electrodes fixed on an upper face of the substrate, a movable electrode plate having an electrode on its lower side and a gap between the group of fixed electrodes on the substrate and the electrode on the movable electrode plate. The guide has at least two carriers that are arranged transversely to the direction of the displacement path and parallel to each other as well as offset in the direction of the displacement path. The step section is able to pass from a rear face side to a front face side of the blade edge while allowing the blade edge to run thereon, when the belt runs in a reverse direction such that the blade edge is in sliding contact with the surface of the intermediate transfer belt. The said micro motor drives the hair styler body to relatively rotate about the handle alongside its axis.
