  • Publication number: 20230045987
    Abstract: A trigger switch includes a trigger, a casing, a compression spring, and a sealing member. The trigger includes a trigger body to which a force is applied when an operator performs a pushing operation, and a trigger shaft extending from the trigger body toward a pushing direction. The casing holds the trigger so as to guide the trigger shaft along the pushing direction when the pushing operation of the trigger is performed. The compression spring is fitted to the outside of the trigger shaft between the trigger and the casing. The sealing member is disposed between the trigger and the casing so as to be fitted to a further outside of the compression spring and cover the trigger shaft and the compression spring.

  • Publication number: 20230005677
    Abstract: A switch according to one or more embodiments may include a movable unit movable in response to an operation. A drive unit is drivable in response to movement of the movable unit. The switch may include an operation-linked unit movable in response to the movement of the movable unit and an operation follower unit spaced from the operation-linked unit to move in response to movement of the operation-linked unit with a magnetic force between the operation follower unit and the operation-linked unit. At least one of the operation-linked unit or the operation follower unit is magnetic. The drive unit is drivable in response to movement of the operation follower unit. The operation follower unit accommodated in a chamber is spaced from the operation-linked unit.

  • Publication number: 20210304975
    Abstract: A trigger switch that is used in electric devices such as various types of electric tools may be provided that drives a drive unit, such as a drive motor of the electric device, by pushing a trigger. A trigger switch includes a mode switching lever that switches between a constant speed mode in which the drive unit is driven at constant speed and a shift mode in which the drive unit is driven by an output corresponding to a pushing amount of a trigger. Further, the mode switching lever includes a regulating portion that regulates the pushing amount of the trigger according to the switched mode.

  • Patent number: 9491430
    Abstract: In a game apparatus, firstly, a depth value in accordance with a state of a virtual three-dimensional space is obtained. Then, an image for left eye and an image for right eye which are obtained by shifting a two-dimensional object that does not exist within the virtual three-dimensional space by a shift amount in accordance with the depth value are synthesized with an image for left eye and an image for right eye which are obtained by capturing the three-dimensional object by a virtual stereo camera, respectively, and the respective synthesized images are rendered, thereby a stereoscopic image is generated. The stereoscopic image obtained as above is outputted to an upper LCD.
