Abstract: A rotor is operable to rotate in a rotating direction, and is provided with five teeth that define five slots therebetween at regular intervals in the rotating direction. A pair of arc-shaped magnets surrounds the rotor, and faces each other through the rotor. A value of a circumferential angle between two adjacent slots with respect to an axis of the rotor is defined as a. A value of a circumferential angle between opposite end edges of an inner surface of the magnet in a circumferential direction of the magnet, which faces the rotor, with respect to the axis of the rotor is defined as b. The value of b falls within a range from 23 to 25 when the value of a is assumed as 12.

Abstract: An actuator includes a driving beam that includes a beam extending in a direction orthogonal to a predetermined axis and supports an object to be driven, a driving source that is formed on a first surface of the beam and causes the object to rotate around the predetermined axis, and a rib formed on a second surface of the beam. A notch is formed in a portion of the driving source corresponding to an end of the rib.

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: An actuator allows miniaturization by realizing back-and-forth rotating motion of, for example, an electric brush without a drive transmitting mechanism which constitutes a separate entity from a drive source. In a movable body (160) of this actuator (100), an outer yoke (110) is provided with inner wall planes (112a and 113a) located opposing each other spaced a predetermined interval apart and magnets (121 and 123) of different magnetic poles opposing each other in the inner walls planes (112a and 113a). The movable body (160) has a center yoke (140) located between the magnets (121 and 124) through air gaps. The movable body (160) is provided with a shaft (150). The fixed body (180) has a coil (170) which is located in the air gaps and which circles the center yoke (140). The fixed body (180) movably supports the movable body (160) through elastic bodies (190). An alternating current supplying section (195) supplies to the coil (170) the alternating current of a frequency virtually equal to the resonance frequency of the movable body (160).
