Patent number: 10571951Abstract: 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.Type: GrantFiled: November 18, 2015Date of Patent: February 25, 2020Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Teruyuki Takizawa, Hironori Tomita, Hideki Shirane, Jiro Seki, Takeshi Nakazawa

Patent number: 10574127Abstract: 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.Type: GrantFiled: March 21, 2017Date of Patent: February 25, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Teruyuki Takizawa, Hironori Tomita, Tsutomu Shimomura, Masakazu Kobayashi, Yasuaki Kameyama, Hirohide Ichihashi
