In this case, in this example, the LCD 31 displays the telephone number of the redial destination at the time of redialing, for example, as shown in FIG. Further, the memory circuit 32 has a table RTBL for storing a telephone number of a redial destination, and the redial table RTBL is configured as shown in FIG. 5, for example.

That is, the number of tables RTBL is n (n
> 1), and these areas Ai (i = 1 to n) include data REGF, TELD, L
STD and CNTD are stored one by one. Where the data REGF
Is a registration flag indicating whether or not the telephone number of the redial destination is registered in the area Ai, and REGF =
The registered area of “0” is an empty area (unregistered), REGF =
The registration area of "1" indicates that the area is in use (registered). The data TELD is data of a telephone number at the time of redialing, and the data LSTD is data of date and time when the last call was made to the telephone number TELD.
CNTD is the number of calls to the telephone number TELD.

The clock circuit 33 outputs the current date and time.
When the telephone number data TELD of the RTBL is displayed on the LCD 31, these keys are used to select the displayed telephone numbers one by one by scrolling. Further, a redial key 35 is a key for executing a redial for the telephone number displayed on the LCD 31, and a mode switch 36.
Is a mode in which when the telephone number of the redial destination is displayed on the LCD 31, the latest telephone number is displayed in order.

At the time of calling from the telephone, picking up the handsets 13 and 14, this is detected by the control circuit 21 through the NCU 11, and the communication circuit 12
1 is connected to the line 1. Then, when the telephone number TNUM of the other party is input from the dial key 23, the data TNUM of the input telephone number is transmitted to the NC through the control circuit 21.
It is supplied to U11, converted into, for example, a DTMF signal, and sent out to the line 1. Therefore, if the other party answers the telephone, the call can be made thereafter as described above.

At the time of dialing, a registration routine 50 is executed by the control circuit 21, and the data TNUM of the telephone number of the other party whose key is inputted is registered in the redial table RTBL of the memory circuit 32. That is, the registration routine 50 starts from step 51, and then proceeds to step 5
2, the telephone number data TN of the key partner
It is checked whether the UM has already been registered in the table RTBL. If the UM has already been registered, the process proceeds from step 52 to step 53.

In this step 53, outgoing time data LSTD of the registration area Arg in which the key-input telephone number data TNUM of the other party in the registration area Ai is registered, is displayed by the clock circuit 33. The date and time are updated to the date and time. Subsequently, in step 54, the data TN of the telephone number of the key-input partner in the registration area Ai
Data on the number of times the UM is registered in the registered area Arg
The CNTD is incremented by "1", and then the routine 50 is ended in step 55.

If it is determined in step 52 that the telephone number data TNUM of the key-input partner has not been registered in the table RTBL, the process proceeds from step 52 to step 61. Then, in this step 61, by checking the registration flag REGF, it is checked whether or not there is an empty area in the registered area Ai of the table RTBL. If there is an empty area, the process proceeds from step 61 to step 62. At 62, the data TNUM of the telephone number of the other party keyed in is registered as data TELD in the free area Aem of the registration area Ai, and the current date and time indicated by the clock circuit 33 are stored in the free area Aem. Is registered as the transmission time data LSTD. Further, data "1" is registered as the transmission count data CNTD in the free area Aem, and the registration flag REGF of the free area Aem is set from "0" to "1".

In this way, in step 62, when the data TNUM of the telephone number of the partner whose key is input is newly registered in the table RTBL, the process proceeds to step 55, and the routine 50 ends.

Further, in step 61, the table
If there is no vacant area in the registered area Ai of the RTBL, the process proceeds from step 61 to step 63. In this step 63, the registration flag REGF of the registered area of the table RTBL having the least number of calls is registered.
Is reset to “0”. However, in this case, when there are two or more registered areas with the least number of transmissions, the registration flag RE of the registered area with the oldest transmission time out of them.
GF is reset to "0".

Then, the process proceeds to a step 62, wherein the data TNUM of the telephone number of the other party inputted by the key is an empty area Aem of the registration area Ai, in this case, REGF = "0" in the step 63. After that, the routine 50 is terminated at step 55.

As described above, each time a call is made, each data REGF, TELD,
LSTD and CNTD are updated or newly registered.

At the time of redialing, the control circuit 21
And the redial is executed by the routine 70.
That is, the routine 70 starts from step 71, and then, in step 72, the mode switch 3
It is checked whether (No. 6) is set to the (newest) display mode (mode) or to the (most recent) display mode (mode). 72 to step 73
In this step 73, the data registered in the table RTBL is sorted for each registered area,
For example, as shown in FIG. 5, the newer the transmission time LSTD is, the lower the registered area is.

Then, the process proceeds to step 75,
In step 75, the pointer k is set to "1". In step 76, the data TELD of the telephone number registered here is extracted from the k-th registration area Ak of the table RTBL. The data TELD of the received telephone number is supplied to the LCD 31. Therefore, the telephone number registered in the k-th registration area Ak of the table RTBL is displayed on the LCD 31. In this case, since k = 1, the telephone number data "3448-3" registered in the first registration area A1.
311 "is taken out, and as shown in FIG.
Displayed at D31.

Then, the process proceeds to a step 77, in which a key input of the selection key 34 and the redial key 35 is awaited, and if either key is pressed, the process proceeds to a step 78. The key input in step 77 is the selection key 34
And the redial key 35 are determined.

If the key input in step 77 is the redial key 35, the process proceeds from step 78 to step 81. In step 81, the key is registered from the k-th registration area Ak of the table RTBL. The telephone number data TELD (currently displayed on the LCD 31 in step 76) is retrieved and supplied to the NCU 11. Therefore, the DTMF signal of the extracted telephone number is transmitted from the NCU 11 to the line 1.

Therefore, in this case, redialing has been executed for the last party called.

In step 78, step 7
If the key input in step 7 is the selection key 34, the process proceeds from step 78 to step 79. In this step 79, if the pressed selection key 34 is the ↑ key, the pointer k is incremented by “1” and pressed. When the selected selection key 34 is the ↓ key, the pointer k is decremented by “1”, and then the process returns to step 76.

Therefore, when the telephone number of the intended redial destination is not displayed on the LCD 31, pressing the select key 34 retrieves the telephone number data TELD of the other party who made the call in the past from the redial table RTBL. This is displayed on the LCD 31, so that the target redial destination telephone number can be found. Then, when the telephone number of the target redial destination is displayed on the LCD 31, when the redial key 35 is pressed, it is possible to call the other party in step 81 as described above.

Further, when the mode switch 36 is set to the display mode in the order of frequency in step 72, the process proceeds from step 72 to step 74,
In this step 74, the data registered in the table RTBL is sorted by registered area,
Those with more CNTDs are replaced so that the registration area becomes younger. When the transmission times CNTD are equal, the new transmission time LSTD is prioritized.

After the sorting, the process proceeds to step 7
Go to 5. Therefore, in this case, the LCD 31 displays the telephone number of the partner whose number of transmissions CNTD is the largest. When the redial key 35 is pressed in this state, the LC
A call is made to the other party displayed in D31.
When the select key 34 is pressed, the telephone number of the other party who made a call in the past is displayed on the LCD 31, and the redial key 3
Press 5 to make a call to that person.
