Description:
BACKGROUND OF THE INVENTION  
         [0001]    The present invention relates to a controller and, more particularly, a battery built-in type controller.  
           [0002]    Normally the game controller is connected to the computer game machine via the cable. However, in a wireless type game controller, the battery is required to be built in the game controller as the power supply of the signal transmitter/receiver circuit. As the battery installing and connecting method in this case, normally the battery contact board is fitted onto the main board in the controller and then the battery contact board and the main board are connected by the soldering. Because of the bending stress applied to the main board via the battery contact board at the time of attaching/detaching the battery, there is such a possibility that the soldered portions of the battery contact board are cracked or the printed-circuit patterns of the main board are disconnected. Also, since the battery contact boards are exposed, there is such a possibility that they are brought into contact mutually to cause the short-circuit.  
           [0003]    Also, normally a pair of multi-directional keys, which are operated by left and right thumbs of a user, and a pair of push keys, which are operated by left and right forefingers of the user, are provided to the controller. The push switch board that receives the operation of the back-and-forth moved push keys is fitted perpendicularly to the horizontal main board. However, a means for holding the switch board more firmly is desired.  
         SUMMARY OF THE INVENTION  
         [0004]    It is therefore an object of the present invention to provide a controller, being enable to eliminate a possibility of damages of a battery contact board portion and a main board and a push switch board portion.  
           [0005]    In order to achieve the above object, according to the present invention, there is provided a controller comprising:  
           [0006]    a battery terminal holding member;  
           [0007]    a switch board holding member, holding a switch board on which a push switch is mounted;  
           [0008]    a parts holding member, mounted on a main board,  
           [0009]    wherein the battery terminal holding member and the switch board are integrally formed on the parts holding member.  
           [0010]    Preferably, the battery terminal holding member holds a battery terminal board, and a rib is formed on the battery terminal holding member such that the battery terminal board is positioned to the battery terminal holding member.  
           [0011]    Preferably, the rib is formed so as to surround the battery terminal board.  
           [0012]    A reinforcement rib is formed on the switch board holding member so as to receive a pushing force generated by an operation of the push switch.  
           [0013]    In the above configurations, since the battery terminal holding member and the switch board holding member are held by the parts holding member that is provided separately from the main board, the stress applied to the main board can be reduced and the reliability and the durability can be improved. Also, since the battery terminal holding member and the switch board holding member are integrally formed as one parts, the number of parts and the man-hour can be reduced.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0018]    An embodiment of the present invention will be explained in detail in accordance with the drawings hereinafter. FIG. 1 is a view showing a main board  1  of a game controller as viewed from a bottom surface, and a reference number  2  shows a parts holder as the essential portion of the present invention. A push key  3  is provided to protrude from the inside of a housing (not shown) to the front side (upper side in FIG. 1). The parts holder  2  is mounted on the main board  1 . (+) electrodes and (−) electrodes of two batteries B contact to (+) contacts  7  and (−) contacts  8  of two battery terminal boards  5 ,  6  that are provided on a center table portion  4 . Also, push switch boards  10  provided separately from the main board  1  are provided perpendicularly to board holder portions  9  formed like two wings that extend leftward and rightward. Push switches  11  provided on the push switch boards  10  are opposed to the back surfaces of the push keys  3 . When the push key  3  is pulled to this side, the push switch  11  is pushed by the push key  3  to turn ON.  
         [0019]    [0019]FIGS. 2A through 2C and FIGS. 3A and 3B show a parts holder  2 . The parts holder  2  is positioned by inserting positioning pins  21  into pin holes in the main board  1 . The pin holes are provided to both left and right ends of the bottom surface of the parts holder  2 . The parts holder  2  is fixed to the main board  1  by engaging hooks  22 , which are provided to a rear edge of the bottom surface, with square holes formed in the main board  1 . Battery terminal holder portions  24 ,  25 , which are surrounded by a rib  23  respectively, are formed on both left and right sides of a square table portion  4 . The square table portion  4  is provided at the center of the parts holder  2 . The rib  23  is formed continuously from the top surface of the table portion  4  to a lower end of a side surface thereof. When the battery terminal board (not shown), which is formed by bending a metal plate, is set to the battery terminal holder portions  24 ,  25 , lower end portions of the battery terminal board are projected downward via holes  26  in the bottom plate shown in FIG. 3B, and then are connected to the power-supply circuit patterns of the main board  1  by the soldering. A (+) contact holder portion  27  and a (−) contact holder portion  28  are provided to the insides of a pair of left and right battery terminal holder portions  24 ,  25  to stand vertically from the top surface of the table portion  4 . A (+) contact and a (−) contact on the upper portion of the battery terminal board, which are bent at a right angle, are latched onto the (+) contact holder portion  27  and the (−) contact holder portion  28  respectively to constitute battery contacts.  
         [0020]    Next, the board holder portion  9  will be explained. The board holder portions  9  arranged on both ends of the parts holder  2  is risen vertically. Ribs  29  are formed on both left and right ends of the back surface of the board holder portion  9  in the vertical direction to hold the switch board that is inserted between the back-surface ribs  29 . As shown in FIG. 2B, reinforcing ribs  30  are provided on the front surface of the board holder portion  9  to withstand the pressure applied by the push keys from the back-surface direction.  
         [0021]    In this manner, the battery terminal board is held by the parts holder  2 , and the back-and-forth movement of the battery terminal board is suppressed by the ribs  23  that surround the periphery of the battery terminal board. Therefore, since the parts holder  2  receives the external force applied to the battery terminal board at the time of the battery exchange, etc., the bending stress, the torsional stress, etc. applied to the main board  1  can be reduced. Also, since the battery terminal board is surrounded by the ribs  23 , such a possibility can be reduced that the conductive substance contacts to the surface of the battery terminal board to cause the short-circuit. In addition, since the switch board is also held vertically by the parts holder, the endurance can be improved.  
         [0022]    In this case, the present invention is not limited to above embodiment, and various variations and modifications can be applied within the technical scope of the present invention. It is a matter of course that the present invention should cover these variations and modifications.
