Abstract: A drive controller of an actuator controls rotation in Pitch direction of a holder in accordance with results of detection by a first magnetic sensor and a first gyrosensor. The drive controller also controls rotation in Yaw direction of the holder in accordance with results of detection by a second magnetic sensor and a second gyrosensor. The drive controller further controls rotation in Roll direction of the holder in accordance with a result of detection by a third gyrosensor.

Abstract: An actuator includes: a movable unit to hold an object to be driven; a fixed unit to support the movable unit thereon to make the movable unit rotatable; and a structure for supporting the movable unit with respect to the fixed unit. The structure includes: a sphere; and a pair of holding members to clamp the sphere between themselves. A space is left to let the sphere roll while shifting a center position thereof with respect to at least one of the pair of holding members.

Abstract: In order to provide an input/output operation device having high operability, an input/output operation device (750) includes: an actuator (165) including a movable unit (180) freely rotatable independently about two axes orthogonal to each other, a fixed unit supporting the movable unit (180) for free rotation, and a drive part driving the movable unit (180) with respect to the fixed unit; a detection circuit part (360) to output a position signal corresponding to a position of an operation part (850); a drive circuit part (350) controlling the drive part; a control calculation processing part (94) controlling the drive circuit part (350); and a rotation body (550) on which the actuator (165) is installed, and which rotates about a rotation axis, in which the control calculation processing part (94) controls the drive of the operation part (850) through use of a coordinate system stationary with respect to a reference rotation angle of the rotation body (550) at different rotation angles of the rotation body (550).

Abstract: Provided is an input/output operation device including: an operation unit, which is operated by an operator; a detection unit, which detects a position of the operation unit to generate a position signal corresponding to the position of the operation unit; a control circuit, which receives the position signal to generate a speed control signal; and a drive circuit, which receives the speed control signal to drive the operation unit, in which the control circuit: (a) causes the position signal to pass through a first filter circuit to generate a speed signal; (b) causes the position signal to pass through a second filter circuit, which has a frequency transmission characteristic that is different from that of the first filter circuit, to generate a correction signal; and (c) adds at least the speed signal and the correction signal together to generate the speed control signal.

Abstract: An actuator includes a first module, a second module, and a mounting unit. The second module supports the first module to make the first module rotatable around each of an X-axis and a Y-axis. The mounting unit supports the second module to make the second module rotatable. The second module has a movable range of 360 degrees or more with respect to the mounting unit. The second module includes a panning drive coil, a tilting drive coil, and a second rolling drive coil.

Abstract: In an actuator (camera driver) according to the present invention, when a movable unit is in a neutral position in which the movable unit has rotated around neither an axis nor an axis, a first synthetic vector and a second synthetic vector are directed toward an object to be driven with respect to a plane including the both axes. The first synthetic vector is defined by synthesizing together two first vectors, pointing toward a pair of magnetic yokes, of magnetic attraction forces between a pair of first driving magnets and the pair of magnetic yokes. The second synthetic vector is defined by synthesizing together two second vectors, pointing toward a pair of magnetic yokes, of magnetic attraction forces between a pair of second driving magnets and the pair of magnetic yokes.
