摘要：
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.
