A roller module for a mouse includes a roller, a ratchet assembly and a counterweight assembly. The ratchet assembly and the counterweight assembly are installed in the roller. When the roller is rotated at a slow speed, the magnet blocks in the counterweight assembly and the magnetic ratchet are magnetically attracted by each other. Consequently, a stepped rotation feel is provided. When the roller is rotated at a fast speed, the magnet blocks are moved with the corresponding counterweight blocks in the counterweight assembly and gradually moved away from the magnetic ratchet along a radial direction. Consequently, a non-stepped rotation feel is provided.

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.

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.

Input device assembly with support pad

A wheel control mechanism includes a support base, a wheel module, a first magnetic module and a second magnetic module. The wheel module, the first magnetic module and the second magnetic module are installed on the support base. The first magnetic module generates a magnetic attractive force to attract a metal ratchet of the wheel module. By adjusting the position of the second magnetic module relative to the first magnetic module, the strength of the magnetic attractive force is changed. Consequently, the rotation of the wheel module results in a tactile feel or does not result in the tactile feel.

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.
