Field of the Invention The present invention relates to a stylus pen, particularly for a stylus suitable for operating a capacitive touch panel. [Prior Art] With the advent of the Personal Digital Assistant (PDA) and the Smart Phone, people can carry such devices with them anywhere, greatly improving the convenience of life. Personal digital assistants and smart phones are mostly equipped with touch panels, allowing users to input information directly through the screen panel, such as a handwriting recognition system. At present, the touch panel is divided into two types: capacitive (reactive) and resistive (Resistive). Resistive touch panels are mostly used for products that can be written with a stylus. The capacitive touch panels mostly use the static induction of the human body and require direct writing with a finger. When the finger is in contact with the touch panel, the static electricity flowing from the human body is shouting a weak current. The face dragon changes according to the current value, which can be contacted by the nose. w Electric Valley touch panel is used in personal digital assistants and smart phones. Due to the small size of the panel, the user's finger size is too large, i fits in! Writing on a sized touch panel. Furthermore, when the user actually operates the capacitive touch panel, the signal is very weak due to the flow (four) capacitive touch panel, and is affected by factors such as finger temperature, humidity, body weight, etc., which are affected by different factors. Drift Ph_enQn, a problem that needs to be overcome in the application of tantalum capacitive touch panels. The reason is that the inventor has felt the above problems, and he has devoted himself to researching and using the theory. Finally, he proposed a stylus suitable for operating a capacitive touch panel, which can effectively improve the operation of the capacitive touch panel. problem. SUMMARY OF THE INVENTION The ultimate goal is to provide a capacitive touch surface == can provide enough static charge to make the capacitive touch panel a capacitive panel. It is more convenient to write on a small size panel. The touch of the 2nd - the purpose of the board is to provide a kind of _ in the operation of the capacitive touch surface = pen,: provide enough static charge to make the capacitive touch panel production, the way to operate the capacitive touch panel The invention provides a stylus suitable for the operation of the lever, which is caused by factors such as the temperature of the finger and the weight of the human body. And a head, set in the pen σ - sufficient static charge to make the capacitor pick up the panel to act. Electrostatic Electricity = In the example, the pen and the pen head can move the human body. Λ 4 type touch panel, so that the capacitive touch panel is made as 200923733. In the second actual cover towel, the stylus of the present invention includes a static generating device for generating the capacitive touch The load required to control the panel. In order to further understand the features and skill of the present invention, the following description of the specific embodiments and drawings of the present invention will be described. [Embodiment] Referring to Fig. 1, a first embodiment of a stylus suitable for operating a capacitive touch panel of the present invention is shown. The stylus 1G includes: a pen holder Μ; and a pen tip 13 ′ is disposed at the end of the pen holder U to raise an electrostatic charge of the ant to activate the capacitive touch panel. In the first embodiment of the present invention, the pen holder i 1 and the pen tip i 3 can conduct the static charge of the human body to the capacitor to be broken, so that the capacitive touch panel is actuated. The tip 13 can be made of a conductive plastic, and the conductive plastic can be made of a plastic material and mixed with at least a conductive material such as metal fiber or graphite. To protect the touch panel, the tip 13 can be made of a soft plastic material that is not easily scratched. Further, in order to make the user's operation smoother, the tip 13 can be made of a material which can reduce the friction coefficient. In order to facilitate the conduction of the static charge of the human body to the capacitive touch panel, the pen holder 11 is also preferably made of a conductive material, such as a metal tube such as copper, Ming, titanium or Mingzhen alloy. However, the pen u is not limited to the conductive material, because the stylus 10 can also be designed such that when the user writes, the hand is in direct contact with the pen 13 and is pulled by the 200923733 person. Further, the following is a method of the second embodiment of the present invention. Face (10), which tears her _ _ as a capacitive touch 筌 _ _ second example of the second. The stylus 20 includes a penholder 21; the ^23/ is placed at the end of the reel 21; and the electrostatic generating device 25, = generates an electrostatic charge to activate the capacitive touch panel. The electrostatic device 25 includes a battery for providing the power required to generate an electrostatic charge. The electrostatic generation 25 can also include the storage of static charges. In the second embodiment of the present invention, the pen 21 and the pen head 23 can also conduct static charge of the human body to the capacitive touch panel, so that the capacitive touch panel can be activated. The conductive plastic can be made of a plastic material and mixed with at least one conductive material such as metal fiber or graphite. To protect the touch panel, you can choose a soft plastic material that is not easy to cause injury. Further, in order to make the user's operation smoother, the tip 23 can be made of a material which can reduce the coefficient of friction. In order to facilitate the conduction of the static charge of the human body to the capacitive touch panel, the pen holder 21 is also preferably made of a conductive material, for example, a metal tube such as copper, aluminum, titanium or aluminum-magnesium alloy. The material is limited. The second embodiment of the present invention is different from the first embodiment of the present invention. The first embodiment mainly uses a stylus to conduct static charge of the human body to the capacitive touch panel to activate the capacitive touch panel. The second embodiment itself is provided with the static electricity generating device 25' directly generating 200923733 static charge 'to make the capacitive touch panel act' belongs to an active stylus and ten . Since the static charge generated by the static electricity generating device 25 is controllable, it can be maintained in a stable state, thereby eliminating drift caused by factors such as finger temperature, wetness, and human body weight. phenomenon. Further, when the static electricity generating device 25 of the stylus according to the second embodiment of the present invention fails, if the power of the battery is exhausted, the stylus of the first embodiment can be provided. The above is a preferred embodiment of the present invention, and is not intended to limit the scope of the invention as claimed. It is also within the scope of the invention to use the equivalent structural changes of the present specification and the drawings.
