BACKGROUND OF THE INVENTION 
   (a) Technical Field of the Invention 
   The present invention generally relates to the wireless mouse, and more particularly to a wireless mouse having a receptacle for the storage of its wireless receiver. 
   (b) Description of the Prior Art 
   The wireless mouse has become very popular recently as it provides greater freedom to its operation and the user has one less cable to manage. To use a wireless mouse, a wireless receiver has to be installed on the computer so as to receive RF signals emitted from the wireless mouse pertaining to its movement and button status. 
   The wireless mouse and its wireless receiver are conventionally designed separately; when they are not in use, they are also stored independently, therefore it is not uncommon that the wireless receiver is misplaced or lost. This in some sense compromises the convenience brought forth by the wireless mouse. 
   SUMMARY OF THE INVENTION 
   The primary purpose of the present invention is to provide a wireless mouse which has a receptacle for the storage of the wireless receiver when the wireless mouse is not in use, so that the wireless receiver would not be misplaced or lost. 
   To achieve the foregoing purpose, the present invention provides a receptacle chamber inside the wireless mouse. When the wireless mouse is not in use, the wireless receiver could be inserted into the receptacle chamber. An internal mechanism inside the wireless mouse automatically holds the wireless receiver in its position within the receptacle chamber. To remove the wireless receiver, a release button is engaged and the wireless receiver would be released and ejected out of the receptacle chamber. 
   The wireless mouse could further be configured with an internal chargeable battery and a jack for the connection with an external power source for recharging the battery.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims. 
   Please refer to  FIG. 1 . As illustrated, the present invention mainly involves a wireless mouse  1  and its wireless receiver  2  which could be stored in a receptacle configured on the wireless mouse  1  when the wireless mouse  1  is not in use. As illustrated in  FIG. 2 , the wireless mouse  1  is composed of a front button cover  11 , a rear cover  12 , a main body  13 , a circuit board  14 , a snap-on element  15 , and a bottom seat  16 . For ease of reference, the direction toward the buttons of the wireless mouse  1  is referred as the front direction and the direction opposite to the buttons is referred to as the rear or back direction hereinafter. The rear cover  12  has a rectangular opening  121  in the rear end to expose an insertion slot  131  of a receptacle chamber  132  configured in the rear section of the main body  13 . A door  17  is configured at the insertion slot  131  by a hinge  172  wound with a biasing spring  171  at the bottom of the insertion slot  131 , such that, when the wireless receiver  2  is inserted into the receptacle chamber  132  via the insertion slot  131 , the door  17  would be pushed open and, when the wireless receiver  2  is removed, the door  17  would return to its original position to close the insertion slot  131  by the biasing spring  171 . 
   As mentioned earlier, the main body  13  has the receptacle chamber  132  configured in the middle of its rear section with the insertion slot  131  at the back end for receiving the wireless receiver  2 . The receptacle chamber  132  has a dimension matching that of the wireless receiver  2  so as to accommodate the wireless receiver  2  completely inside. The main body  13  is positioned on top of the circuit board  14  and allows a control wheel  141  of the circuit board  14  exposed to the outside of the main body  13 . The circuit board  14  is supported by and fixedly installed on the bottom seat  16 . The snap-on element  15  is configured on the bottom seat  16  at a location corresponding to the bottom of the receptacle chamber  132  for the positioning and locking of the wireless receiver  2  inside the receptacle chamber  132 . 
   Please refer to  FIG. 3 . To store the wireless receiver  2 , the wireless receiver  2  is inserted into the receptacle chamber  132  via the insertion slot  131 . The door  17  would be forced open and the biasing spring  171  is thereby held in a compressed state under the wireless receiver  2 . When the wireless receiver  2  is removed from the receptacle chamber  132 , the door  17  would return to its original position to close the insertion slot  131  by the biasing spring  171 . Therefore, by examining the state of the door  17 , a user can tell whether the wireless receiver  2  is stored in the receptacle chamber  132  or not. When the wireless receiver  2  is inserted into the receptacle chamber  132 , the front end of the wireless receiver  2  would press against a spring element  133  and the spring element  133  would remain in a compressed state as the wireless receiver  2  is held in its position in the receptacle chamber  132  by the snap-on element  15 .  FIG. 4  is an enlarged top view showing the details of the spring element  133 . As illustrated, the spring element  133  has an end  134  fixedly attached to a locking element  137  and the other free end  135  for the compression of the wireless receiver  2 . As the free end  135  is compressed by the wireless receiver  2  toward the fixed end  134 , a resilient force is established against the wireless receiver  2 . When the snap-on element  15  releases the wireless receiver  2 , the resilient force of the spring element  133  would eject the wireless receiver  2  out of the insertion slot  131  so that a user could easily remove the wireless receiver  2 . 
   Please refer to  FIGS. 3 and 6 . The bottom seat  16  has a protruding tenon  161  in the rear section of the bottom seat  16  for embedding into a central through opening  151  of the snap-on element  15 . In addition, the bottom seat  16  has a pair of positioning pins  162  for holding the snap-on element  15  therebetween. When positioned as such, the snap-on element  15  has its vertical blade  152  extended into the receptacle chamber  132  via a through opening  136  configured at the bottom of the receptacle chamber  132 . On the surface of the wireless receiver  2 , there is a corresponding groove  21  for the embedding of the vertical blade  152  when the wireless receiver  2  is inserted into the receptacle chamber  132 . On the snap-on element  15 , the vertical blade  152  is surrounded by a U-shape cutting  153  such that the vertical blade  152  could swing up and down flexibly. Therefore, when the wireless receiver  2  is inserted into the receptacle chamber  132 , the vertical blade  152  of the snap-on element  15  is pushed downward until the wireless receiver  2 &#39;s groove  21  is on top of the vertical blade  152 . At that instant, the vertical blade  152  is extended into the groove  21  and thereby positions and locks the wireless receiver  2  inside the receptacle chamber  132 . To remove the wireless receiver  2 , a release button  154  configured at the bottom of the snap-on element  15  is pressed and, with the protruding tenon  161  as a pivot point, the vertical blade  152  is moved downward to leave the groove  21 . Therefore the resilient force of the spring element  133  ejects the wireless receiver  2  out of the receptacle chamber  132 . As shown in  FIG. 5 , the release button  154  is exposed by and hid inside a concaved button groove  163 . As such, the release button  154  wouldn&#39;t get in the way of wireless mouse  1 &#39;s sliding operation. 
   At last, a chargeable battery (not shown) could be installed inside the wireless mouse  1  to provide the required electricity. A jack  100  is provided for connecting the chargeable battery to an external power source via appropriate cabling for recharging. 
   It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above. 
   While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
