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: 10077836Abstract: A selector includes a lever guide, an operating lever, and a stopper. The lever guide has first and second movable-path slits therein. The first movable-path slit extends from a first position to a second position along a first direction. The second movable-path slit extends along a second direction different from the first direction as to intersect the first movable-path slit at an intersection position. The second movable-path includes a third position. The operating lever is movable in along the first and second movable-path slits. The operating lever is configured to move to the first position through the first and second movable-path slits. The stopper slides and contacts the operating lever when the operating lever moves from the third position to the first position. The stopper slides and contacts the operating lever when the operating lever moves from the first position to the third position.Type: GrantFiled: February 10, 2017Date of Patent: September 18, 2018Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Hironori Tomita, Teruyuki Takizawa, Hideki Shirane, Takeshi Nakazawa
