Abstract

This invention provides a capacitive stylus pen including a conductive plate, a joint and a conductive pen body is provided, wherein the joint is connected between the conductive plate and the conductive pen body such that the conductive pen body could move around the conductive plate. In another embodiment, a capacitive stylus pen includes a conductive pen body and a universal joint connected to the conductive pen body, wherein the universal joint has at least a quasi-flat surface such that the universal joint has both functions of the conductive plate and the joint mentioned above. Thus, the capacitive stylus pens mentioned above both provide convenience to use by position input.

Claims

1. A capacitive stylus pen, comprising:

a conductive pen body; and

at least one universal joint connected to the conductive pen body, wherein the universal joint has at least one quasi-flat surface.

2. The capacitive stylus pen as claimed in claim 1, wherein the conductive pen body comprises a root and two branches, wherein one end of the branch connected to the root and another end of the branch connected to the universal joint.

3. The capacitive stylus pen as claimed in claim 1 and 2, wherein the quasi-flat surface of the universal joint being configured to stick on a touch panel.

4. The capacitive stylus pen as claimed in claim 3, wherein the cross-section view of the quasi-flat surface of the universal joint is selected from the group consisting of a square, a circular form, a triangle form and a rhombus form.

5. The capacitive stylus pen as claimed in claim 3, wherein the square measure of the quasi-flat surface is larger than 1 mm².
