The operation of the present invention described above will be described with reference to FIG. 2 through FIG. 5.  
         [0020]    [0020]FIG. 2 is an outer sketch of the telephone applied by the memory dialing method according to the present invention.  
         [0021]    [0021]FIG. 3 is an another outer sketch of the telephone applied by the memory dialing method according to the present invention.  
         [0022]    The structure of the telephone is applied by the structure of the telephone of Utility model number 4250, Korea patented Mar. 17, 1999.  
         [0023]    That is, the telephone in FIG. 1 is similar with the integrated telephone in FIG. 6 of the Utility model number 4250.  
         [0024]    Herein, the first memory unit  5  and the second memory unit  7  are corresponding to first memory unit  45  and the second memory unit  46  in FIG. 4 of Utility model number 4250.  
         [0025]    In FIG. 1, the first memory unit  5  includes a plurality of removable ROM card inserting units, on which ROM cards is inserted, on main body of the telephone as in FIG. 2 through FIG. 5 of the Utility Model 4250. And corresponding hot keys are disposed around the ROM card inserting units, whereby the memory dialing can be made easily.  
         [0026]    Also, the second memory unit  7  in FIG. 2 includes a plurality of hot keys and memory regions corresponding to the hot keys.  
         [0027]    In other words, the telephone shown in FIG. 1 applied by the memory dialing method according to the present invention is an integrated telephone having same structure as that in FIG. 2 through FIG. 5 of the Utility Model number 4250.  
         [0028]    However, in the present invention, a ROM card  11  among those plurality of ROM cards  10 ˜ 19  in the first memory unit  5  is able to use a pre-paid telephone card sold by a telecommunication company, whereby a long distance or an international phone call is able to be made more easily.  
         [0029]    Hereinafter, a process of memory dialing by recording the connect number of the telecommunication company and the card number on the telephone card  11  will be described with reference to FIG. 4 as follows.  
         [0030]    [0030]FIG. 4 is a flow chart showing an embodiment of signal flowing of the memory dialing method according to the present invention. The memory dialing method by recording the connect number of the telecommunication company and the card number on the telephone card  11  will be described with reference to FIG. 1 through FIG. 3.  
         [0031]    First, the center processor unit  6  is able to perform the memory dialing function by storing and reading the memory telephone number by the user&#39;s request on the telephone card such as storing and reading the telephone number stored in the ROM cards  12 ˜ 19  in the first memory unit  5 .  
         [0032]    The telephone card is inserted into the inserting unit (S 40 ), and push the input/end key installed on the switch matrix  8 , and then the store mode is set.  
         [0033]    In the state, a hot key K 1  installed around the telephone card  11  is pushed, then the address for the telephone card  11  is set.  
         [0034]    In that state above, the connect number of the telecommunication company (for example, 02-397-7777) is inputted using number keys installed on the switch matrix  8  (S 41 ). At that time., the center processor unit  6  identifies the connect number and records the connect number on the telephone card  11 . In addition, the center processor unit  6  sets a certain waiting time T 1  for voice guide message.  
         [0035]    After that, when a corresponding language is chosen (for example, Korean  1 , English  2 , Japanese  3 , and Chinese  4 ), the center processor unit  6  identifies the language select number, records it on the telephone card  11 , and sets a certain waiting time T 2  for voice guide message.  
         [0036]    In addition, the card number (for example, 9 numbers+#) of the telephone card is inputted (S 42 ). At that time, the center processor unit  6  identifies the card number, records(stores) the card number on the telephone card  11  (S 43 ), and sets a certain waiting time T 3  for voice guide message (S 44 ). Then the store mode is ended.  
         [0037]    In addition, the process described above may be performed twice, whereby two memory telephone numbers are stored in that telephone card  11 . In that case, the hot key K 1  is pushed shortly in order to set a store region for one memory telephone number (for example, connect number and the card number), and the other hot key K 1  is pushed longer in order to set a store region for the other memory telephone number.  
         [0038]    As described above, the process of recording the connect number of the telecommunication company, language select number, and the card number on the telephone card  11  may be performed by the user. However, it is desirable that the distributor of the telephone card  11  (for example, the telecommunication company or the telephone card selling company) records that information on the telephone card  11  as a customer service.  
         [0039]    After the memory telephone numbers are stored in the telephone card, if the user wants to make a domestic or an international call using the telephone card  11 , the user inserts the telephone card  11  into the inserting unit and pushes the hot key K 1  installed around the inserting unit (S 45 ). At that time, the center processor unit  6  reads the connect number of the telecommunication company from the telephone card  11  (S 46 ), drives the DTMF driving unit  4 , whereby the DTMF signal corresponding to the connect number is generated (S 47 ). The DTMF signal is transmitted to an exchanger through the speaking circuit unit  1  and the local loops L 1  and L 2 .  
         [0040]    In addition, during the waiting time T 1  set earlier in the record mode, voice guide messages of “please select your language” are outputted in some languages. At that time, the center processor unit  6  reads the language select number from the telephone card  11  and drives the DTMF driving unit  4 , whereby the DTMF signal corresponding to the language is generated and transmitted through the above process.  
         [0041]    Therefore, a voice guide message is outputted during the next waiting time T 2  in the selected language (for example, in Korean), such as “please input your card number”. At that time, the center processor unit  6  reads the card number from the telephone card  11  and drives the DTMF driving unit  4 , whereby the DTMF signal corresponding to the card number is generated and transmitted through the above process.  
         [0042]    The connect number of the telecommunication company, the language select number, and the card number are automatically outputted through the above process, after that a voice message is outputted during the next waiting time T 3 , such as “please input the telephone number of the receiver”. At that time, the user is able to talk with counterpart by performing the dialing process.  
         [0043]    For example, if the user wants to make a domestic call, the user is able to talk by dialing the local number and the telephone number of the other. And if the user wants to make an international call, the user dials country code (for example, 1), local number ( 123 ), and the phone number of the other ( 123 - 4567 ), and then is able to speak to the other.  
         [0044]    On the other hand, as for another embodiment of the present invention, a method of memory dialing an entire number using a hot key when the user makes a domestic or an international call will be described with reference to FIGS. 5A and 5B.  
         [0045]    [0045]FIGS. 5A and 5B are flow charts showing the signal flowing of the another embodiment of the memory dialing method according to the present invention. The present embodiment will be described in detail with reference to FIG. 1 through FIG. 3. In addition, as for the processes (S 40 ˜S 44 ) same as in FIG. 4, same reference numerals are used, and descriptions for that are omitted.  
         [0046]    First, the storing process will be described. The user presses the input/end key installed in the switch matrix  8 , whereby the store mode is set. In that state, in order to set a ROM card in which the memory telephone number will be stored among ROM cards ( 12 ˜ 19 ) of the first memory unit  5 , the user presses the corresponding hot key. That is, the user set the ROM card in which the abbreviated number will be stored according to the inputted key (S 50 ).  
         [0047]    After that, the user inputs a special key (‘*’ or ‘#’) for setting the ROM card  11  (S 51 ) so as to automatically transmit the connect number of the telecommunication company and the telephone card number stored in the telephone card  11  when memory dialing is made.  
         [0048]    In addition, the user inputs the remaining numbers. That is, the special key is stored in the ROM card (S 52 ). For example, if the phone number which the user wants to store for the memory dialing is domestic number, the user inputs local number         telephone number of the receiver +#, and presses input/end key. Also, if the number which the user wants to store for the memory dialing is an international phone number, the user inputs country code         local number          telephone number of the other +#, and presses the input/end key.  
         [0049]    The user is able to store the abbreviated number as he/she wants in the respective ROM cards  12 ˜ 19  of the first memory unit  5  by repeatedly performing the above processes (S 53 ), and presses the hot key installed the corresponding ROM card, whereby the memory dialing is made (S 54 ). The memory dialing process will be described as follows.  
         [0050]    At that time, the center processor unit  6  reads the abbreviated number stored in the corresponding ROM card of the first memory unit  5 . In the store mode, the telephone card  11  is set as special key (‘*’ or ‘#’), and therefore the connect number of the telecommunication company and the card number is read, after that the corresponding DTMF signal is generated and transmitted to the exchanger (S 55 ).  
         [0051]    And then, the abbreviated number read from the corresponding ROM card  12  of the first memory unit  5  is transmitted. For example, if the number after the ‘*’ or ‘#’ stored in the ROM card is a domestic number, the local number and the phone number +# are read, and the corresponding DTMF signal is outputted. If the number is an international call number, the center processor unit  6  reads the country code, local number, and the phone number+#, and outputs corresponding DTMF signal, whereby the phone call is made (S 56 ).  
         [0052]    That is, as described above, the numbers dialed whenever the telephone card is used, that is the connect number of the telecommunication company and the card number are stored in the telephone card  11 , and the numbers are memory dialed using the corresponding hot key K 1 . Also, the numbers stored in the telephone card  11  is set as a special key ‘*’ and stored in a ROM card among the ROM cards in the first memory unit  5  or in a memory region on the second memory unit  7 , and the remaining numbers are stored, whereby the entire phone number is able to be dialed at once.  
         [0053]    After that, if the telephone card is used up or lost, so the telephone card should be replaced, the user does not need to store the abbreviated numbers again if the user buy a telephone card in which the connect number and the card number is recorded.  
         [0054]    For example, even if the user does not buy the telephone card  11  in which the connect number and the card number are recorded, the user only store the connect number and the card number on the telephone card  11  as described above. That is, the contents stored in the respective ROM cards  12 ˜ 19  of the first memory unit  5  do not need to be changed.  
         [0055]    The present invention is not limited in the embodiments above. That is, when a call from outer country to interior or from another country to the other country is made by memory dialing, the same effects as described above can be obtained by storing the numbers and memory dialing as described above.  
         [0056]    Also, in the descriptions above, setting a certain waiting time T 1 ˜T 3  when storing a abbreviated number is described for the voice guide message. However, in case that a voice signal is detected by a signal detecting unit  3  and the signal DET is transmitted to the center processor unit  6 , the numbers are able to be transmitted within a shorter period, whereby the memory dialing time can be reduced.  
         [0057]    In the descriptions above, the telephone card  11  fabricated as same size as that of the ROM card  12 ˜ 19 . However, the telephone card may be fabricated larger than that of the ROM card as shown in FIG. 3, and a ROM  11 B is installed on the telephone card  11 A, then the telephone card is able to be used by inserting into a separate inserting unit  11 C. In that case, the ROM  11 B is connected as same method as that of the ROM cards  11 ˜ 19  in the first memory unit  5 .  
         [0058]    Also, the present invention is not limited to the wire telephone. That is, the present invention is able to be applied to mobile phone. And in that case, when the number of the other is stored or transmitted, only the mobile phone (for example, 01x-xxx-xxxx) number is needed without dialing the local number.  
       INDUSTRIAL APPLICABILITY  
       [0059]    As so far described, according to the memory dialing method for the telephone, in case that a user make a domestic or an international call, that is, the user should presses many keys, the user is able to make memory dialing conveniently at a low expense. Because an abbreviated number are recorded in the telephone card to thereby directly use the abbreviated dialing or an abbreviated phone number assigning key portion of the phone number and the remaining numbers are stored in the ROM card which is attached and detached to and from a phone set to thereby make an abbreviated dialing.
