Title: Replaceable multiple-functional interface card

Description:
FIELD OF THE INVENTION  
      The present invention relates to devices for transmitting data through interface cards, and particular to a replaceable multiple-functional interface card.  
     BACKGROUND OF THE INVENTION  
      In the prior art, devices, such as GPS (global positioning satellite) receivers, blue tooth devices, digital cameras, etc., are confined to be connected to an interface card with the same specification. In another prior art for improving the above said defect, the device is installed with a plurality of inserting slots each for receiving a respective interface card so as to form a one to one mapping. The general used interface cards include USB interface cards (Universal Serial Bus interface card), SD interface cards (Secure Digital interface card), MS interface cards (Memory Stick interface card); CF interface cards (compact flash interface cards); MD interface cards (IBM Micro Drive interface card); SM interface cards (Smart Media interface card); MMC interface cards (Multi Media Card), etc. Or these interface cards are connected to the device by using an adaptor having a memory card reader interface, or a USB interface, or an IEEE 1394 interface through a transmission line to a computer mainframe. This is known in the prior art. Thereby, some of these prior arts emphasize the combination of the interface and the adaptor. In one prior art, a PCMCIA network card is extended with a microwave antenna, however, this has no relation to the content of the present invention which will be described in the following.  
     SUMMARY OF THE INVENTION  
      Accordingly, the primary object of the present invention is to provide a replaceable multiple-functional interface card for inserting into an inserting seat. The inserting seat has a rotary seat; and one side of the rotary set is installed with an inserting hole. The replaceable multiple-functional interface card comprises an interface card; a receptacle extended from one end of an interface card; a plug extended from one side of the receptacle; plug being wound by three insulating wires; the three insulating wires dividing the plug into four surfaces. When the plug is inserted into the inserting hole, data in the interface card is transferred to the inserting seat through the four surfaces. The plug is replaceable so as to replace interface card. The inserting seat is the inserting seat of a GPA satellite signal receiver or a blue tooth device, or a digital camera.  
      The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

     DETAILED DESCRIPTION OF THE INVENTION  
      In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.  
      With reference to  FIGS. 1 and 2 , the replaceable multiple-functional interface card of the present invention is illustrated. The replaceable multiple-functional interface card of the present invention includes an interface card  1 . A receptacle  10  is extended from one end of an interface card  1 . A plug  11  is extended from one side of the receptacle  10 . By replacing the plug  11 , the interface card  1  can is replaceable so that the data to be read is replaceable. An inserting seat  2  with respect to the plug  11  has a rotary seat  3 . One side of the rotary set  3  is installed with an inserting hole  30 . The interface card  1  can be inserted into the inserting hole  30  of the rotary seat  3 . The plug  11  is wound by three insulating wires  110 ,  111 , and  112 . The three insulating wires  110 ,  111 , and  112  divides the plug  11  into four surfaces  1101 ,  1102 ,  1103  and  1104  which can be inserted into the inserting hole  30 . Data in the interface card  1  can be transferred to the inserting seat  2  through the four surfaces  1101 ,  1102 ,  1103  and  1104 .  
      In the present invention, the front and rear surfaces are contact surfaces for positive and negative electrodes and the middle two surfaces are used to send and receive signals.  
      In use of the present invention, when the plug  11  of the interface card  1  is inserted into the inserting hole  30 , the interface card  1  can be replaced as desired. The interface card  1  used can be selected from one of USB interface cards  4  (Universal Serial Bus interface card), SD interface cards  5  (Secure Digital interface card), MS interface cards  6  (Memory Stick interface card); CF interface cards  7  (compact flash interface cards) (see  FIGS. 3, 4 , and  5 ); MD interface cards (IBM Micro Drive interface card); SM interface cards (Smart Media interface card); MMC interface cards (Multi Media Card), etc.  
      In another embodiments of the present invention, one end of a GPS satellite signal receiver seat  8  is formed with one inserting hole  80 , see  FIG. 3 . Furthermore, in  FIG. 4 , it is illustrated that one end of a blue tooth receiver seat  81  is installed with an inserting hole  810 . Moreover, in FIG.  5 , one end of a digital camera  9  is installed with an inserting hole  90 . Thereby, the plug  11  of the receptacle  10  extended from one of the USB interface cards  4  (Universal Serial Bus interface card), SD interface cards  5  (Secure Digital interface card), MS interface cards  6  (Memory Stick interface card); CF interface cards  7  (compact flash interface cards) can be inserted into the inserting holes  80 ,  810 , or  90 . By the arrangement of the present invention, the plug  11  is replaceable rapidly.  
      With reference to  FIGS. 6 and 7 , the present invention provides a replaceable multiple-functional interface card. When the plug  11  of the interface card  1  is inserted into the inserting hole  30 , the interface card  1  is rotatable for adjusting the position of the interface card  1 .  
      Advantages of the present invention will be described here. The plug is replaceable rapidly. For example, GPS satellite receiver seats, blue tooth receiver seats, digital camera receiver seats are replaceable so that data transmitted by different protocols can be transferred between the seats and the interface cards. Moreover, operation of the present invention is rapid and easily. Multiple devices (such as notebook computers, personal digital assistances etc.) can be used with multiple peripherals (such as satellite receivers, blue tooth devices, digital cameras).  
      The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
