Abstract: An actuator includes a first driving beam that is connected to an object to be driven and includes multiple first beams extending in a direction orthogonal to a first predetermined axis, ends of each adjacent pair of the first beams being connected to each other via one of first turnaround parts such that the first driving beam forms a zig-zag bellows structure as a whole; first driving sources formed on first surfaces of the first beams; and ribs formed on second surfaces of the first beams at positions that are closer to the first predetermined axis than the first turnaround parts. The first driving sources are configured to move the first driving beam and thereby rotate the object around the first predetermined axis.

Abstract: A light scanning device includes a light emitter configured to emit light; an optical scanner configured to cause the light to scan; a light receiver configured to receive returning light as scanning light from the optical scanner being reflected or scattered on an object; and an optical scanning controller including processing circuitry configured to control the optical scanner. The optical scanner includes a rotating polyhedron configured to include a plurality of reflective surfaces, to cause the light to scan around a first axis by reflecting the light on a reflective surface while rotating around the first axis; a supporter configured to support the rotating polyhedron; and a rotating mechanism configured to rotate the supporter around a second axis that crosses the first axis, to cause the light reflected on the reflective surface to scan around the second axis.

Abstract: An operation input device includes a coil, an operation part configured to be displaced in an axial direction of the coil by the action of an operation input, a core whose positional relationship with the coil is changed by the displacement of the operation part, a yoke placed outside the coil, and a magnet configured to generate a magnetic flux that flows through the core and the yoke. The coil is configured to output a signal corresponding to the amount of the displacement of the operation part. The operation part is caused to move by an electric current flowing through the coil and the magnetic flux of the magnet.

Abstract: Disclosed is an actuator that generates the reciprocating rotational motion of an electric toothbrush or similar without employing a drive transmission mechanism as a separate entity from a drive source. An actuator (100) includes a fixed body (110) comprising an outer yoke (140) having inner wall planes that respectively oppose the magnetic pole planes of unlike poles of a magnet (150) with a predetermined gap therebetween. A coil (122) is arranged to encircle the magnet (150) between the magnetic pole planes of the unlike poles of the magnet (150) and the inner wall planes of the outer yoke (140) that respectively oppose the magnetic pole planes of the unlike poles, and this coil (122) is movably supported as a movable body (120) by way of an elastic member (130) fastened to the fixed body (110). The reciprocating rotational motion of the movable body (120) is afforded by the supply of an alternating current of a frequency approximately equivalent to the resonant frequency of the movable body (120) from an alternating current supply (180) to the coil (122).
