Abstract: A mouse device includes a wheel control mechanism and a control unit. The control unit is electrically connected with a magnetic force module and a rotating speed detector of the wheel control mechanism. Under control of the control unit, a first direction current or a second direction current is selectively provided to drive the magnetic force module. The flowing directions of the first direction current and the second direction current are opposite. Consequently, the rotating mode of the wheel control mechanism can be switched between different modes.

Abstract: A mouse device includes a casing and a roller module. The roller module is installed within the casing. The roller module includes a roller wheel, a movable magnet, a first magnet and a second magnet. In response to a repulsive force between the first magnet and the movable magnet, the roller module is in a tactile feel mode. In response to an attractive force between the second magnet and the movable magnet, the roller module is in a smooth scrolling mode.

Abstract: A mouse device includes a casing, a switch, a button, a travel distance adjustment and a knob structure. The button is exposed to a top side of the casing. A first end of the travel distance adjustment assembly is contacted with the button. A second end of the travel distance adjustment assembly includes an internal thread structure. The internal thread structure of the travel distance adjustment assembly is engaged with an external thread structure of the knob structure. While an operating part of the knob structure is rotated, the knob structure is not moved and the travel distance adjustment assembly is moved upwardly relative to the knob structure to push the force-exerted part upwardly. Consequently, a triggering speed of the switch is increased.

Abstract: A joystick module includes a base, a joystick body, a joystick cover and a second protruding edge. The base includes a casing and a first protruding edge. A top part of the casing has an opening. The first protruding edge is formed on a periphery of the opening of the casing. The joystick body is installed in the base. A first end of the joystick body is protruded through the opening so as to be rotated. The joystick cover is installed in the base and connected with the joystick body. In response to a rotation of the joystick body, the joystick cover is correspondingly rotated. During the rotation of the joystick body, a part of the second protruding edge is contacted with an inner surface of the casing. When the part of the second protruding edge is contacted with a part of the first protruding edge, the rotation of the joystick body is limited.
