[New content] Therefore, the purpose of the present invention is to provide a double-ended stylus suitable for different operational uses and which does not easily damage a capacitive touch panel.于疋' This new dual-head stylus is suitable for a capacitive touch panel, 3 palms, a first stylus and a second stylus. The stem is made of a soft, electrically conductive material, including a second portion at opposite ends and a second end. The first stylus tip is made of a soft conductive material and is connected to the first end and has a circular arc end face. The first stylus tip is made of a soft conductive material and is connected to the second end portion and has a circular arc end face. The curvature of the arc end face of the first stylus is larger than the curvature of the arc & face of the second stylus head, so that the first stylus and the second are under the same force and the same contact angle When the stylus is in contact with the capacitive touch panel, the contact area between the first stylus and the capacitive touch panel is smaller than the contact area between the second stylus and the capacitive touch panel. The two-head stylus of the present invention provides two different specifications of the pen tip for different (four) purposes. In particular, the first stylus pen having a smaller size is provided, and (4) having a larger sizing phase. a second stylus tip, thereby providing a different choice for fine operations (eg, drawing) or for a user interface having touch images (or touchable sensing areas) of different sizes or Operating system (for example, the i〇s operating system for iPhone and iPad that Apple introduced at present, the Windows 8 operating system launched by the company, and the editing system developed by *G〇〇gle). [Embodiment] The foregoing and other techniques (10), features, and effects of the present invention will be apparent from the following detailed description of the preferred embodiment. Referring to FIG. 2 and FIG. 3, the dual head of the present invention is suitable for a capacitive touch panel, comprising: a case, a head 3 and a second touch pen head 4. The pen 2, the first stylus, the pen: two made of (4) conductive material and itself is a flexible end 22 and I# S' located at the opposite end of the inter-section 21 The IU and a second end 23 extend into the central opening 24. In the present & S material 2, the axial extension rubber is made. In the embodiment of the present invention, the pen holder 2 is provided with a wall hole 211 ′ which is electrically conductively connected to the inter-chamber portion 21 and which is perpendicularly connected to the central tunnel 24 and has a wide upper surface of the wearing portion 2 for attaching a book decoration. rope. The order \= has a plurality of annular ribs formed on the outer peripheral surface and located between the wall holes 2ι and the =P23, and is used for increasing the grip of the stylus 2 by the soft conductive The material is made of a contact portion 31 including an end face of the -3m end portion 22 and a portion of the contact portion 3 1 that is retracted into the first end of the flute flute to the first flute 22 The portion of the first stylus head 3 is hollow and communicates with the pen pressure opening and opening, thereby increasing the recovery capability of the first stylus head 3 a / 1. In the preferred embodiment, the first stylus tip 3 is made of conductive rubber. The second stylus head 4 is made of a soft conductive material and includes a face 41 facing the second end. The second end portion 23 is extended in the cross section and inserted into the hole 41 of the recess M442543 of the second stylus head 4, and the central tunnel 24 can communicate with the recess 41 of the second stylus head 4. Thereby, the recovery ability of the second stylus pen 4 after the pressure deformation is increased. In the preferred embodiment, the second stylus head 4 is made of a conductive rubber. Referring to FIG. 4, the first stylus head 3 and the second stylus head bucket respectively have a circular arc end surface for operatively and deformably touching the capacitive touch panel, and stopping the touch The capacitive touch panel can be elastically restored to its original shape. In addition, the diameter of the first stylus 3 is smaller than the diameter of the second stylus 4. Preferably, the diameter of the first stylus 3 is 4 to 6 mm, and the diameter of the second stylus 4 is 7 to more preferably, the diameter of the stylus 3 is about 5.5 mm. The diameter of the second stylus head 4 is about 8 mm. In particular, the curvature of the arc end surface of the first stylus head 3 is greater than the curvature of the arc end surface of the second stylus head 4, so that the same application is performed. When the first stylus 3 and the second stylus 4 are in operative contact with the capacitive touch panel, the first stylus 3 and the electric valley touch panel are The contact area is smaller than the contact area of the second stylus head 4 and the capacitive touch panel. Preferably, the curvature of the arc end surface of the first stylus head 3 is twice as large as the curvature of the arc end surface of the second stylus head 4. In summary, the difference in curvature and the difference in size between the arc end faces of the first stylus 3 and the second stylus 4 can be selected to touch different sizes of touch images or to perform For different operational purposes, the non-hard pen holder 2 made of conductive rubber is reused, so that the chance of inadvertently damaging the M442543 capacitive touch panel can be reduced, so that the purpose of the present invention can be achieved. The above-mentioned ones are only the preferred embodiments of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent changes and modifications made by the patent scope and the new description contents in the present invention. , are still within the scope of this new patent.
