Abstract
A mouse roller module includes a roller, a sensing unit, an electromagnet and a control unit. The roller includes a ring-shaped magnet and a rotating shaft. The rotating shaft is extended along a first direction. When an external force is exerted on the roller, the ring-shaped magnet is rotated about the rotating shaft. The sensing unit is located near the roller to sense a pole of the ring-shaped magnet. The roller is arranged between the electromagnet and the sensing unit. The electromagnet and the ring-shaped magnet interact with each other to generate a magnetic force. The control unit is electrically connected with the sensing unit and the electromagnet. The control unit controls the electromagnet and the ring-shaped magnet of the roller to generate the magnetic force according to a result of sensing the pole of the ring-shaped magnet by the sensing unit.
