An input/output operation device includes an actuator detection circuit part, a drive circuit part, a drive control calculation processing part that controls the drive circuit part, and a rotation body on which the actuator is installed. The actuator includes a movable unit freely rotatable independently about two axes orthogonal to each other, a fixed unit supporting the movable unit for free rotation, and a drive part driving the movable unit with respect to the fixed unit. The detection circuit part outputs a position signal corresponding to a position of an operation part. The drive circuit part controls the drive part. The rotation body rotates about a rotation axis, in which the control calculation processing part controls the drive of the operation part through use of a coordinate system stationary with respect to a reference rotation angle of the rotation body at different rotation angles of the rotation body.

Input/output operation device

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.

An input/output operation device () includes: an operation part (); a movable unit () including a loosely fitted space inside, a main body supporting the operation part () and including a first loosely fitted surface () exposed in the loosely fitted space, and at least one drive magnet (); a fixed unit including a second loosely fitted surface () in point- or line-contact with the first loosely fitted surface of the movable unit, a holder () supporting the movable unit for free rotation, a base () including a space for accommodating at least a part of the movable unit and supporting the holder, and at least one drive coil (); a drive part to rotate the movable unit with respect to the fixed unit; and a detector to detect a position of the operation part in the fixed unit. One of the first and second loosely fitted surfaces includes an inner peripheral surface formed into a recessed portion, and another one of the first and second loosely fitted surfaces includes at least one protruded spherical surface.

An input and output operation device includes an actuatorincluding an operation unit; a movable unit having the operation unit and at least one attraction magnet mounted thereon and including a concaved portion in a part thereof; a secured unit including a convexed spherical surface loosely engageable with at least one magnetic member and the concaved portion of the movable unit, the convexed spherical surface being point-contactable or line-contactable with the concaved portion of the movable unit by a magnetic attraction force, the secured unit supporting the movable unit such that the movable unit is freely rotatable as centered around a spherical center of the convexed spherical surface; a first driving unit rotating the operation unit as centered around an X-axis passing the spherical center; a second driving unit rotating the operation unit as centered around a Y-axis perpendicular to the X-axis; a third driving unit rotating the movable unit as centered around a Z-axis that is perpendicular to the X-axis and the Y-axis and is a central axis of the operation unit; and a detector detecting a first rotation angle and a second rotation angle of the operation unit around the X-axis and the Y-axis; and also includes a detection circuit unitgenerating first and second rotation angle signals; a control computation processing unitgenerating first and second target rotation angle signals; and a driving circuit unitgenerating a signal usable to drive the first and second driving units.
