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 button, a switch, a linkage element, a plate body, a supporting element and an adjusting element. A triggering part of the plate body is arranged between the linkage element and the switch. When the adjusting element is moved, the supporting element is correspondingly moved. Consequently, the supporting element is selectively contacted with the first fulcrum or the second fulcrum. While the button is pressed down and the linkage element is moved downwardly toward the triggering part, the triggering part is swung around a first fulcrum or a second fulcrum of the plate body to push the switch. Consequently, the switch is triggered.

Abstract: A mouse device with a button feedback mechanism is provided. The mouse device includes a mouse body and a button module. The mouse body includes an upper case, a lower case and a hollow cylinder. The button module includes a button, an elastic element, an attracting element and a suspension arm. The elastic element is disposed within the hollow cylinder and located under the pressing part. The button is contacted with the elastic element. The attracting element is installed on the upper case. The suspension arm includes a connection segment and a free segment. The connection segment is penetrated through the hollow cylinder and connected with the elastic element. The free segment is located under the attracting element. Consequently, the mouse device provides the sound feedback and the touch feedback.

Abstract: A mouse device includes a casing, a top cover, an adjusting module and a pressing part. The casing is covered by the top cover. The top cover is movable relative to the casing. The top cover includes a saw-toothed plate. The saw-toothed plate is inserted into an inner portion of the casing and contacted with the adjusting module. The pressing part is connected with the adjusting module. When the pressing part is pressed to trigger the adjusting module, the saw-toothed plate is pushed by the adjusting module and the top cover is moved form a first position to a second position. Consequently, a shape of the mouse device is changed. The shape of the mouse device is changeable according to the size of the user's palm.

Abstract: An input device assembly with a support pad is provided. The input device assembly includes the support pad and an input device. The support pad includes a first main body and a first magnetic attraction element. The first main body has a first bottom surface and a first curvy surface. The input device includes a second main body and at least one second magnetic attraction element. The second main body has a second bottom surface and a second curvy surface. The first curvy surface of the support pad is contactable with one of plural portions of the second curvy surface of the input device. The first magnetic attraction element and one of the at least one second magnetic attraction element are magnetically attracted by each other. Consequently, the support pad is in close contact with the input device.

Abstract: A mouse roller module includes a roller assembly, a sensing unit and a control unit. The roller assembly includes a stator and a rotator. When the roller assembly is in a first usage mode, the rotator is rotated relative to the stator in response to an applied force of a user. A rotating speed of the rotator relative to the stator is sensed by the sensing unit. If the rotating speed of the rotator relative to the stator reaches a threshold value when the roller assembly is in the first usage mode, the roller assembly is switched form the first usage mode to a second usage mode under control of the control unit. While the first usage mode is switched to the second usage mode, the roller assembly is switched to an enabled state, so that the stator drives rotation of the rotator.
