More Information
Summary:A mouse device includes a casing and a roller module. The roller module is disposed within the casing. The roller module includes a scroll wheel, a magnetic ratchet, a supporting element and a permanent magnet. The scroll wheel includes a concave structure. The magnetic ratchet is disposed within the concave structure of the scroll wheel. While the scroll wheel is rotated, the magnetic ratchet is correspondingly rotated. The magnetic ratchet includes a ratchet frame and plural tooth structures. The plural tooth structures are discretely arranged on an inner surface of the ratchet frame. While the magnetic ratchet is rotated with the scroll wheel, the plural tooth structures of the magnetic ratchet are sequentially transferred through a region over the permanent magnet, and a magnetic attractive force between the corresponding tooth structure and the permanent magnet is generated.
