Abstract
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 supporting seat, a magnetic ratchet and a permanent magnet. The supporting seat includes a first support part and a second support part. The magnetic ratchet is arranged between the scroll wheel and the first support part of the supporting seat. As the scroll wheel is rotated, the magnetic ratchet is correspondingly rotated. The magnetic ratchet includes plural tooth structures. The permanent magnet is installed on the first support part of the supporting seat. The permanent magnet is aligned with one of the plural tooth structures of the magnetic ratchet. While the magnetic ratchet is rotated with the scroll wheel, a magnetic attractive force between the plural tooth structures and the at least one permanent magnet is generated.
