  • Publication number: 20240011755
    Abstract: A position detection device includes a magnet and first to ninth magnetic sensors. The first to ninth magnetic sensors include first to third magnetic sensors. An output of each of the first to third magnetic sensors switches when a shift lever shifts between position M and position N. Switching of outputs of the first and third magnetic sensors among the first to third magnetic sensors and switching of an output of the second magnetic sensor which is a remaining one of the first to third magnetic sensors are inverted when the shift lever shifts between position M and position N.

  • Patent number: 11624632
    Abstract: A position detection device includes two detection systems that are respectively fed from power supply systems different from each other, and displace together with a shift lever. Each detection system can output detection patterns with four digits. A detection pattern when being located at a given position is different from a detection pattern when being located at another position. In any detection pattern, outputs of certain two digits among the four digits are set so as to be identical to each other, and to be different from outputs of two other digits. Alternatively, outputs of certain three digits among the four digits are set to be identical to each other, and to be different from an output of another digit.

  • Patent number: 11353313
    Abstract: A position detection device detects a current positon of a operation member among positions including a predetermined position and includes a detection system that includes a part to be detected and 3N magnetic sensors S. The operation member can move to the positions in N (?3) different directions from the predetermined position. Movement of the operation member between the predetermined position and another position cause outputs from three of the magnetic sensors to be switched. The magnetic sensors of which outputs are switched by a movement of the operation member between the predetermined position and a first position are all different from the magnetic sensors of which outputs are switched by a movement of the operation member between the predetermined position and a second position.

  • Patent number: 10599177
    Abstract: An input device includes a knob, a detector, an electromagnetic brake, an elastic member, and a controller. The detector detects a rotation angle of the knob. The electromagnetic brake regulates rotation of the knob. The elastic member is provided between the knob and the electromagnetic brake. When the current position of the knob in the circumferential direction is not the target position for rotation regulation of the knob, the controller does not activate the electromagnetic brake. When the current position of the knob in the circumferential direction is the target position for rotation regulation of the knob, the controller determines whether to regulate rotation of the knob based on a rotation direction of the knob, or on a rotation angle of the knob that shifts from the holding position of the knob in the circumferential direction due to deformation of the elastic member.

  • Patent number: 9920831
    Abstract: A pattern of a rotational operation force is changed by a state of a device of an input object. An input device includes a knob, a rotation shaft body that rotates together with the knob, a rotation controller that is capable of changing a rotational operation force, a detector that detects a rotational position, a controller, and a storage that stores a plurality of patterns. The controller reads a pattern from the storage according to a pattern signal input from an outside and controls the rotation controller when the knob is operated to be rotated according to a rotational position detected by the detector and the read pattern.

  • Publication number: 20120154938
    Abstract: A lens driving device suppresses inward deformation of posts when the winding of a conductive wire generates a winding pressure. A lens driving device 1 includes a holder 10 that holds a lens unit 13. The holder 10 is movable in an optical axis direction of the lens unit 13. A magnet 20 surrounds the lens unit 13 in a radial direction of the lens unit 13. The magnet 20 is fixed to the holder 10. A coil 60 surrounds the holder 10 in the radial direction. The coil 60 faces the magnet in the radial direction. Posts surround the holder in the radial direction. The posts to which the coil is wound extends in the optical axis direction. A beam connects ends of the posts facing the same direction in the optical axis direction with each other. The beam is connected to each end of the posts.
