Abstract

A mouse device includes a roller module. The roller module includes a base member, a scroll wheel, a magnetic conductor, a swingable arm, a driving motor and an actuating element. The scroll wheel is installed on the base member. The magnetic conductor is located beside the scroll wheel. When the scroll wheel is rotated, the magnetic conductor is correspondingly rotated. The swingable arm is installed on the base member. The swingable arm includes a magnetic element. The swingable arm is swingable relative to the magnetic conductor. When the swingable arm is swung to a first position, the magnetic element is aligned with the magnetic conductor. Consequently, a magnetic attraction force between the magnetic element and the magnetic conductor is generated. When the swingable arm is swung to a second position, the magnetic attraction force between the magnetic element and the magnetic conductor is eliminated.

First claim

What is claimed is:

1. A mouse device comprising a roller module, the roller module comprising:
a base member;
a scroll wheel installed on the base member;
a magnetic conductor located beside the scroll wheel, wherein when the scroll wheel is rotated, the magnetic conductor is correspondingly rotated;
a swingable arm installed on the base member, wherein the swingable arm comprises a magnetic element, and the swingable arm is swingable relative to the magnetic conductor, wherein when the swingable arm is swung to a first position, the magnetic element is aligned with the magnetic conductor, so that a magnetic attraction force between the magnetic element and the magnetic conductor is generated;
a driving motor installed on the base member; and
an actuating element arranged between the driving motor and the swingable arm, and having a curvy surface, wherein while the driving motor drives the actuating element to rotate in a first direction, the curvy surface of the actuating element is contacted with the swingable arm, so that the swingable arm is moved along the curvy surface of the actuating element and swung from a first position to a second position, wherein when the swingable arm is swung to the second position, the magnetic attraction force between the magnetic element and the magnetic conductor is eliminated.

2. The mouse device according to claim 1 , wherein while the driving motor drives the actuating element to rotate in a second direction opposite to the first direction, the swingable arm is moved along the curvy surface of the actuating element and swung from the second position to the first position, wherein when the swingable arm is swung to the first position, the swingable arm is detached from the curvy surface of the actuating element.

3. The mouse device according to claim 2 , wherein the roller module further comprises a noise reduction element, and the base member further comprises a first protrusion stopper and a second protrusion stopper, wherein the noise reduction element is connected with the actuating element, the first protrusion stopper and the second protrusion stopper are opposed to each other, and the first protrusion stopper and the second protrusion stopper are arranged between the driving motor and the actuating element, wherein while the driving motor drives the actuating element to rotate in the first direction, the noise reduction element is correspondingly rotated, and the noise reduction element is contacted with the first protrusion stopper, so that the actuating element is positioned at the first position, wherein while the driving motor drives the actuating element to rotate in the second direction, the noise reduction element is correspondingly rotated, and the noise reduction element is contacted with the second protrusion stopper, so that the actuating element is positioned at the second position.

4. The mouse device according to claim 1 , wherein the scroll wheel comprises a fixed shaft, and the driving motor comprises a driving shaft, wherein the scroll wheel is pivotally coupled to the base member through the fixed shaft, the magnetic conductor is sheathed around the fixed shaft and located beside the scroll wheel, the actuating element is sheathed around the driving shaft of the driving motor, and an extending direction of the fixed shaft and an extending direction of the driving shaft are in parallel with each other.

5. The mouse device according to claim 1 , wherein the swingable arm comprises:
a swinging part, wherein the magnetic element is installed in or installed on the swinging part, wherein when the swingable arm is swung to the first position, the swinging part is aligned with the magnetic conductor, and the magnetic element is arranged between the swinging part and the magnetic conductor;
a push part, wherein while the driving motor drives the actuating element to rotate in the first direction, the curvy surface of the actuating element is contacted with the push part; and
a pivotal part connected between the swinging part and the push part, wherein the swingable arm is pivotally coupled to the base member through the pivotal part.

6. The mouse device according to claim 5 , wherein the base member comprises a bearing, wherein the bearing is arranged between the magnetic conductor and the actuating element, and the swingable arm is pivotally coupled to the bearing through the pivotal part.

7. The mouse device according to claim 6 , wherein the roller module further comprises a bearing sleeve, wherein the bearing sleeve is sheathed around the bearing of the base member, and the bearing sleeve is arranged between the bearing and the pivotal part of the swingable arm.

8. The mouse device according to claim 1 , wherein the roller module further comprises an elastic element, wherein a first end of the elastic element is contacted with the swingable arm, and a second end of the elastic element is contacted with the base member.

9. The mouse device according to claim 1 , wherein the magnetic conductor is a gear.

10. The mouse device according to claim 1 , wherein the mouse device further comprises a casing, wherein the casing has a perforation, the roller module is installed within the casing, and a portion of the roller module is exposed outside the casing through the perforation.
