    • There is provided a unit circuit comprising: a capacitive element having a first electrode, a second electrode, and a dielectric layer interposed between the first electrode and the second electrode; a transistor having a gate electrode connected to the first electrode, a first terminal supplied with one of a low potential and a high potential, and a second terminal connected to a driven element; a first switching element controlling electrical connection between the gate electrode of the transistor and the second terminal; and a second switching element connected to the second electrode. A potential of the first electrode is set to a predetermined potential higher by a threshold voltage of the transistor than a first potential by turning on the first switching element, and the potential of the first electrode is set to the first potential by supplying a first operation signal to the second electrode through the turned-on second switching element in a state that the first electrode is electrically isolated from the predetermined potential by turning off the first switching element. A second period in which the potential of the first electrode is set to the predetermined potential by turning on the first switching element and a second operation signal is supplied to the second electrode through the turned-on second switching element is provided subsequently to a first period in which the potential of the first electrode is set to the first potential. In a state that the first electrode is electrically isolated from the predetermined potential by turning off the first switching element after the second period is ended, the potential of the first electrode is set to a second potential by supplying a third operation signal to the second electrode through the turned-on second switching element. Here, the first potential and the second potential have opposite polarities when the predetermined potential is used as a reference potential.

    • A dust-screening member is shaped like a plate as a whole. A vibrating member is adjacent to one side of the dust-screening member, arranged on the surface along the one side, and configured to produce, at the surface, vibration having a vibrational amplitude perpendicular to the surface. A drive unit is configured to drive the vibrating member to produce the vibration on the surface, such that peak ridges of the vibration form a closed loop and an area including a center of the closed loop is surrounded by a node area having almost no vibrational amplitude. When a length of a side in a dust-screening member virtual rectangle corresponding to a long side of a vibrating member virtual rectangle is assumed to be LF, and a length of a long side in the vibrating member virtual rectangle is assumed to be LPFF, LPFF/LF has a dimension of 0.7.
