Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a touch pen module, and more particularly to a touch pen module which uses at least one bulge or at least one notch to assemble a pen tip and a pen body.  
         [0003]     2. Description of the Related Art  
         [0004]     Conventional touch pen used to touch the display surface of an electronic device to select and execute functions thereof has a separate pen tip made of a specific material.  FIG. 1  shows a conventional touch pen  100  including a pen tip  102  and a pen body  104 . The material of the pen tip of a conventional touch pen comprises polyoxymethylene (POM) which is special and expensive, and must be manufactured independently. However, the pen body of a conventional touch pen is usual and can be manufactured by a common process such as injection molding. To integrate the pen tip and the pen body to complete a touch pen, the pen tip and the pen body must be assembled and glued artificially by workers. The pen tip and the pen body can also be assembled by placing the pen tip in the mold of the pen body during the injection molding process.  
         [0005]     The integration processes of the pen tip and the pen body set forth have several drawbacks. For example, artificially assembling and gluing the pen tip and the pen body by workers is hard to standardize. The quantity of the glue used on every pen tip and every pen body is hard to unify thereby reduce the reliability and the yield ratio of the touch pen. Placing the pen tip in the mold of the pen body during the injection molding process would increase the complexity, cycle time and cost of production.  
         [0006]     Thus it is necessary to provide a new touch pen module to resolve the drawbacks set forth. It is towards those goals that the present invention is specifically directed.

The bulges  206  are located on the elongation  204  and the notches  212  are on the inner surface of the socket  210 . The number of the bulge and the notch shown in  FIG. 2A  is just an example, not a limitation.  FIG. 2B  shows a touch pen as a result of assembling the pen tip  202  and the pen body  208 . The elongation  204  and the bulges  206  of the pen tip  202  are inserted into the socket  210  and the notches  212  respectively. The pen tip  202  and the pen body  208  are integrated and fixed by the wedging or joining of the bulges  206  and the notches  212 . Although the shapes of the bulges  206  and the notches  212  shown in  FIG. 2A  are hemisphere, the shapes of the bulges  206  and the notches  212  can also be other geometrical forms. Because the pen tip  202  is assembled with the pen body  208  via the bulges  206  and the notches  212 , the pen tip  202  can be replaced easily if necessary. The pen tip  202  can be colored or be fluorescent. The pen body  208  can be manufactured by injection molding and the pen tip  202  can be made of polyoxymethylene (POM).  
         [0031]     In a second embodiment of the invention, the touch pen module of the invention also uses bulges, notches and a socket to assemble a pen tip and a pen body, while the notches are located on the pen body and the bulges and the socket are on the pen tip.

FIG. 6B  shows a top view of a touch pen as a result of assembling the pen tip  602  and the pen body  604 . The elongations  608  and the bulges  606  of the pen tip  602  are inserted into the socket  612  and the holes  610  respectively. The pen tip  602  and the pen body  604  are integrated and fixed by the wedging or joining of the bulges  606  and the holes  610 . The bulges  606  insert into and through the holes  610  and become a part of the outer surface of the pen body  604 . However, the bulges  606  can also just insert into the holes  610  but not completely through the holes  610 , and the holes  610  are caves.  FIG. 6C  shows a front view of the touch pen as a result of assembling the pen tip  602  and the pen body  604 . The shapes of the bulges  606  and the holes  610  shown in  FIG. 6A  are only examples, not limitations, the shapes of the bulges  606  and the holes  610  can also be other geometrical forms. Because the pen tip  602  is assembled with the pen body  604  via the bulges  606  and the holes  610 , the pen tip  602  can be replaced easily if necessary. The pen tip  602  can be colored or be fluorescent. The pen tip  602  can be made of POM and the pen body  604  can be manufactured by injection molding.  
         [0035]     The touch pen module of the invention which utilizes bulges, an elongation, notches and a socket to assemble a pen tip and a pen body has advantages of high reliability, production convenience and low cost which the conventional touch pen lacks.
