  • Publication number: 20200403339
    Abstract: A connector includes: an insulator that includes a first main surface being a surface that faces a cable, and a rear surface being a surface on an opposite side of the first main surface; a contact that electrically connects the cable and a substrate; and an actuator that is rotatable about a rotation axis parallel to the substrate. The actuator includes a plate-shaped side wall that intersects with the rotation axis. The side wall includes a base portion including a second main surface that is a surface that faces the first main surface when the actuator is rotated in a direction closer to the cable, and a recognition portion that protrudes from the base portion. A distance from the rotation axis to a leading end of the recognition portion in a direction orthogonal to the second main surface is larger than a distance from the rotation axis to the rear surface.

  • Publication number: 20200019252
    Abstract: A touchpad includes a flat surface portion and a protruding solid portion having a hemispherical shape. The operation recognition part recognizes a gesture operation performed on an operation region of the touchpad. An operation validity determination part determines that only a rotating slide operation with respect to a lower periphery of the solid portion is a valid operation even at a time of an operation lock invalidating the gesture operation. In a case where the rotating slide operation is performed at the time of the operation lock, the operation lock is released, and at the same time, a specific function is executed by an AP execution part.
