  • Publication number: 20250182985
    Abstract: An input device includes a housing, a movable member at least partially housed in the housing and reciprocably supported by the housing along a Z-axis direction, a soft magnetic member fixed to the housing, and a magnet fixed to the movable member facing the soft magnetic member in a Y-axis direction. The soft magnetic member includes a strong attraction portion where a magnetic attraction force between the magnet and the soft magnetic member is relatively strong and a weak attraction portion where a magnetic attraction force between the magnet and the soft magnetic member is relatively weak. The strong attraction portion is disposed so that one end is located at an inner side relative to one end of the magnet in the Z-axis direction, and the weak attraction portion includes a portion extending outward relative to the one end of the strong attraction portion in the Z-axis direction.

  • Patent number: 12293873
    Abstract: An input device which is capable of imparting a magnetic operational reaction force, includes a stationary member, a magnetic member fixed to the stationary member, a movable member at least partially housed in the stationary member to which the magnetic member is fixed, and a driving device including a magnet fixed to the movable member and coils fixed to the stationary member, configured to move the movable member in a first direction relative to the stationary member, wherein the magnet is magnetized along a second direction perpendicular to the first direction, wherein the coils have bundles of turns constituted by conductive wires, and the conductive wires in the bundles of turns extend along a third direction perpendicular to each of the first direction and the second direction, and the conducting wires are juxtaposed along the first direction.
