FIELD OF THE INVENTION 
     The present invention is related to an interface of hard discs body device, especially the interface of a standard hard discs that connect with hot swap interface. The present invention is a device to hot swap memory. 
     Usually we have to use proper instruments and equipment to deal with the working situation in which a large amount of data exits. Particularly on the high speed information expressway, different kind of work needs comparatively saving device; for example, the desk top outer users have to use hard discs and CD-R; the image workers need a device that has a mass storage and can be easily carried, like MO and ZIP. Furthermore, digital camera users need Compact Flash, Smart Media, and PCMCIA-ATA Card. Therefore; the exchanges of the data among different data saving devices become a regular work. 
     Nowadays, the memory like PCMCIA-ATA Card, Compact Flash Card or Smart Media are small and easy to be carried, so they are largely used in communication equipment, digital cameras, notebook computers, personal digital assistants, laptop computers, digital recorders and portable telephones. Since there is no proper interface in the PC, users have to transfer the data saved in the above products to the PC by means of extra devices. 
     In the market now, there is a PCMCIA (Personal Computer Memory Card International Association) to read the data in the memory when the data are transferred among data saving devices, however; in this way, users have to buy expensive equipment and the operation procedure is very complicated, that is, users have to transfer the ISA or PCI signals on a motherboard through a Host Bus Adapter into the Common Memory Mode signals of PCMCIA. One of the drawbacks of this system is the difficulty of the design, and the other one is, to communicate with the PC, the controller has to match up with the driver of the socket service and the card service. The worst drawback is when users set up the above equipment, they have to take the host apart, and then put the interface into the ISA or PCI socket, and reset the device driver of the operating system. All the above procedure is very complicated and cost much. 
     Some people use universal serial bus (USB) readers, which have to connect with controller to transfer the USB signals into ATA-IDE signals to be the interface of communicating with the PC. Others use parallel port to connect with reader to install driver to transfer the parallel port signals into data saving device signals. All the methods above will waste the interface and occupy the sockets of the computer. It not only needs expensive equipment but also very inconvenient for us to use. 
     Most of the popular desktop computers use parallel ports and USB to be the interface to communicate with the PC. 
     In view of the pressing demand of plugging the memory in the PC to transfer the data, and the standard hard discs interface can directly support to hot swap the memory, the inventor develops a hard discs body device for hot swapping interface by means of his long term accumulated experience on application and manufacture in that field and through continuous testing and improvement. 
     SUMMARY OF THE INVENTION 
     The primary object of the present invention of the hard discs body device for hot swap interface is the standard hard discs interface connects with the hot swap interface to control the loopback. The memory directly plugs in the hot swap interface to control the switch of the power and to supply the hard discs interface, hot swap interface to make the storage data readable. 
     The secondary object of the present invention of the hard discs body device for hot swap interface is the standard hard discs interface connects with hot swap interface, and directly install in the computer for directly plugging in the memory. This can economize the user of the space and save the cost.

     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in FIG.  1  and FIG. 2, the present invention of a hard disc body device for hot swap interface, which consists a hot swap interface, a reader  30  and a control loopback  40 . 
     On one side of the hot swap interface  20 , as shown in FIGS. 1,  2 ,  3 , and  4  are two lines of pins  21 , which are paralleled and its number are decided. At the ends are two sets of detected pins  211 ,  211 ′,  212  and  212 ′. Pin  211  and pin  212 ′ do not link together; neither does pin  212  and pin  212 ′. Besides, there are two power pins  213  and  213 ′ placed in the middle. The hot swap interface  20  has a concave socket  22  on the outside of the pin  21 . On the other side of the hot swap interface  20  is a cable socket  23 ; one end of a bus  24  connects with the cable socket  23  and the other end connects with the standard hard discs interface  25 . 
     The reader  30 , as shown in FIGS. 1,  2 , and  5 , has a housing for the hot swap interface  20 . A socket  31  sets up at the corresponding place of socket  22  for memory  32  to fit in. The memory  32  has the same numbers of signal socket  33 , which is corresponding to the pin  21  and they can fit to each other. The signal socket  33  has a CD 1  signal socket  33  and a CD 2  signal socket  332 , which are corresponding to the detected pins  211  and  212 . The signal socket  331  and  331 ′ of the CD 1  are connected, so are the signal socket  332  and  332 ′ of the CD 2 . 
     The control loopback  40 , as shown in FIGS. 3,  4 ,  5  and  6 , is a PCB  41 , which is placed on the side of the hot swap interface  20 . Two guide lines  411  and  412  are paralleled on the PCB  41 . Each one has an end to connect the detected pin  211  and pin  212 . The other ends of the guide line  411  and  412  connect with the gateway  421  of the operation loopback  42  and an anti gateway  422  connects with the gateway  421 . Another anti gateway  423  connects the anti gateway  422 . The anti gateway  423  connects with the transistor  431  of a switch loopback  43 . A guide line  44  of the switch loopback connects the power pin  213  and  213 ′, in the mean time, the power pin  213  and  213 ′ connectc with the hot swap interface  20  and connect with the standard hard discs interface  25  by means of the cable socket  23 . In this case, the hot swap interface  20 , the standard hard discs interface  25  and the memory  32  are connected structure. Another two electric current restricted components  45  and  46 , corresponding to the guidelines  411  and  412  is located between the detected pins  211 ,  212  and the gateway  421 . The electric current restricted components  45  and  46  form a ground connection. The electric current restricted components  45  and  46  are resistances that have high resistiveness saled in the market. 
     According to the above structure, as shown in FIG. 2,  4  and  5 , the standard hard discs interface  25  has 40 pins signal lines. The standard hard discs interface connects with cable slot  23  by means of the bus  24  to form a connected pins  21 , which is corresponding to the hot swap interface  24 . The hot swap interface has multi pins, which are over 40 pins signal lines. (The present invention chooses to use the standard equipment of 50 pins, 68 pins are fine, too). Among the rest pins of the pins  21  of the host swap interface  20 , the detected pin  211  correspondingly connects the guidelines  411  and  412 , and the power pins  213  and  213 ′ correspondingly connect with the ATA-IDE addressing mode signal of the memory  32 . 
     To address the memory  32 , as shown in FIG.  1  and FIG. 5, the insert  31  of the reader  30  has not been correspondingly connected with the memory  32 . Although the power pins  213  and  213 ′, which is corresponding to the No.  13  and No.  38  signal pins, are ground connecting, the detected pins  211  and  211 ′ of the hot swap interface  20  are not connected, neither are pins  212  and  212 ′. The reader  30  correspondingly connects power pins  213 , 213 ′ and ground connection ( 0  pressure). The reader  30  is in save mode; that is, it is not under electric conducted circumstance. 
     When in use, the memory  32  inserts in the slot  31  of the reader  30  (as shown in FIGS. 1,  5  and  6 ). The CD 1  signal slot  331  and CD 2  signal slot  332  connect with the detected pins  212  and  212 , and also connect with the signal slot  331 ′ through signal slot  331  of the CD 2 . So that the signal slot  331 , signal slot  331 ′, detected pin  211  and detected pin  211 ′ are connected. In the meantime, detected pin  212  and  212 ′ are connected. For all of this, the signal slot  331  of the CD 1  and the signal slot  332  of the CD 2  can connect to electricity by grounding. 
     In the present invention, the signal slot  331  of the CD 1  and the signal slot  332  of the CD 2  are ground connected at the same time by connecting the detected  211 ,  211  of the hot swat interface  20  and the corresponding guide line  411 ,  412  of PCB  41 . Turn on the power, output signals ( 0  or low) through gateway  421  of the operational loopback  42  and then use the anti gateway  422  to connect the gateway  423  to postpone to proper time to output  0  or low signals. Then boot the transistor  44  to form an open statement. In order to read the storage data of the memory  32  for the users, the guide line  45  connect with power and connects the pins  213  and pins  213 ′ to supply power to the hot swap interface  20  and the standard hot discs interface  25 . 
     When users pull out the memory  32  or when the socket  31  of the reader  30  has not connected to the memory  32 , as shown in FIGS. 5 and 6, the detected pin  211   211 ′  212  and  212 ′ are disconnected and this form a specific signal (signal  1 ). The specific signals (signal  1 ) is re-operated by the operational loopback  42  or gateway  421  and output a specific signal (signal  1 ) to keep the transistor  44  in a disconnected condition. The switch loopback  43  and the standard hard discs interface  25  are disconnected and there is no power to supply the reader  30 , so that the switch loopback  43  connects with the reader  30  in a disconnected and power saved condition. 
     It can be clearly understood from the above description, the present invention use the hot swap interface  20  to detect whether the memory  32  insert in the reader  30  or not to output signals ( 0 , low or  1 ). The signals are received by the gateway  421 , anti gateway  422  and anti gateway  423  of the operational loopback  42 . And the memory  32  inserts in or not is known by reconfirming and re-operating. As a result of this, the switch loopback  43  turns on off at an appropriate time, so that the memory  32  can be inserted in the reader  30  to connect the power or pulled out to disconnect, and becomes a power saved condition. That is, the memory  32  can hot swap to support the hard disc interface  25  to get to the hot swap function. 
     When users insert the memory  32  in the reader  30  slantwisely, the CD 1  signal  331  and CD 2  signal  332  of the memory  32  female joint with the detected pins  211  and  212  or the signal slot  331  and signal slot  332 ′ female joint with detected pin  211 ′ and  212 ′ may be in a bad connection. The detected pins  211  and  212  are in a disconnected condition, as shown in FIGS. 5 and 6, at this time, the present invention can connect the guide line  411  and  412  by the parallel detected pins  211  and  212 , so the either detected pins  211  or  212  is in disconnected, a specific signal ( 1  signal) comes out correspondingly, and the gateway  421  produces a signal after it receives the signal. The transistor  44  of the switch loopback  43  is disconnected and does not move. In this case, users have to insert the memory  32  correctly to use and it must have the function to prevent idleness. 
     The guideline  411  and  412  connect power and transfer to the anti gateway  422  and  423  through the gateway  421 . By the inner circuit design collocates electric capacity to form a registered function. The registered function can delay the set up time and to produce a signal to delay the boot of the transistor  44  to lower the rapidly increasing power supply. So that the power supplies can be stable and normal to protect the inner loopback from the harm of overlarge and suddenly happened electric current. It not only prevents the power from disconnecting but also can confirm the memory  32  can insert correctly. 
     The standard hard discs interface  25  of the present invention connects with the hot swap interface  20 . The memory  32  can directly insert in the pin  21  of the hot swap interface  20  by the control loopback to control the supply of the power. The present invention uses low price equipment to insert memory  32  in hot swap way. So, users do not have to use expensive equipment, such as pcmcia, driver or controller in complicated procedure. 
     What is described above is only a better example of the present invention of the memory hot swap of the hard discs interface device but cannot limit the scope of putting the present invention into practice, to wit, the relative changes and modifications conducted according to the claims of the present invention shall remain within the scope covered by the said claims. The hot swap interface connects with control loopback so that the standard hard discs interface; the reader and the hot swap interface are connected. The memory can be directly inserted in or pulled out to switch the supply of power. It cost less and it is easy to be assembled. Besides, the memory is suitable to be used for hot swap.
