First, the storage of a telephone number and the dialing operation will be explained. When the record switch 17 is pressed down, the control unit 2 detects this and puts the memory 3 into a storage state according to the procedure stored in the memory 4. Next, when the subscriber selection switch 13 is pressed down, the control section 2 detects this and selects the storage area of the memory 3 corresponding to the subscriber selection switch 13, at the same time erasing the previously stored contents. It becomes possible to memorize new information. Also, at this time, the switch number input by the subscriber selection switch 13 is displayed on the display 5. While these operations are being performed, subscriber selection switch 1
Data such as the switch number 3 is temporarily stored in the control unit 2.

Next, press the number switches 14 in the order of the phone numbers to be stored. Through this operation, the control unit 2 identifies this number and writes this telephone number into the corresponding storage area of the previously selected memory 3.
This telephone number is displayed on the display 5. When writing of the telephone number is completed, the off switch 16 is pressed.

Next, the dialing operation will be explained. When the call switch 15 is pressed down, the control section 2 detects this and operates the switching circuit 9 according to the procedure stored in the memory 4. As a result, the line from the line terminal 10 is switched from the off-hook detection circuit 11 side to the dial signal circuit 6 side, and is closed at the dial signal circuit 6. The dial tone from the line is amplified by an amplifier 7, amplified by a speaker 8, and used as a monitor.

Next, the subscriber selection switch 13 corresponding to the subscriber to be called is pressed. This operation causes the control section 2 and the memory 4 to operate, and the telephone number of the other subscriber is read from the corresponding storage area of the memory 3. The signal corresponding to the read telephone number is converted into a dial signal by the control section 2 and sent to the line terminal 10 via the switching circuit 9. When the telephone number is sequentially read out, converted into a dial signal, and sent out, a ringing tone of the line is applied through the line terminal 10 to a switching circuit 9, an amplifier 7, and a speaker 8 in this order, and this ringing tone can be monitored.

When the other party answers, the voice of the other party can be heard from the speaker 8. When the handset of the telephone 12 is raised, the off-hook detection circuit 11 operates, and the control section 2 switches the line of the switching circuit 9 to the off-hook detection circuit 11 side, and a call is made using the handset.

Next, the operation of the number switch 14 for dialing a subscriber whose telephone number is not stored will be explained.

When the call switch 15 is pressed, the line is closed in the same manner as in the dialing operation described above, and the dial tone can be monitored on the speaker 8. Next, when the number switches 14 are pressed in the order of the telephone numbers, the control section 2 and memory 4 are operated, and the telephone numbers are temporarily stored in a specific memory of the memory 3 and read out at the same time. The signal corresponding to the read telephone number is converted into a dial signal by the control section 2 and sent to the line terminal 10 via the switching circuit 9. The following numbers are stored in the memory 3 in response to pressing of the number switch 14, and are converted into dial signals and sequentially sent to the line terminals 10.

When the other party answers, a call is made using the handset of the telephone 12 in the same manner as the above-mentioned dialing operation.

Next, the dialing operation by the subscriber selection switch 13 and number switch 14, which is a feature of the present invention, will be explained.

First, in the same way as the dialing operation, the call switch 15 is pressed, and then the subscriber selection switch 13 in which the station number is stored is pressed. By this operation, the control unit 2 and memory 4 read out the telephone number from the corresponding storage area of the memory 3. On the other hand, when the subscriber selection switch 13 is pressed, the memory 3
A subscriber switch number corresponding to the subscriber selection switch 13 is stored in a specific storage area in the form of three digits, such as D13. Note that this D is displayed in hexadecimal and is a code that can be distinguished from the number by the next number switch.

Next, when the subscriber selection switch 13 is pressed and then the number switch 14 is pressed, the subscriber switch numbers of the subscriber selection switch 13 (the above D1
Following 3), the number of the number switch 14 is stored.

This stored telephone number is read out from the memory 3.
For example, D13× stored in a specific storage area of
××…×(D13 is the subscriber selection switch 13
The numbers stored from the storage area corresponding to the station number to the station number, XXX...X indicate the numbers that were pressed on the number switch 14 in sequence following the pressing of the subscriber selection switch. ) are read out sequentially, converted into a dial signal, and sent out. When dialing of the area number corresponding to D13 is completed, the number pressed with the number switch
It sequentially reads out xx...x and converts it into a dial signal and sends it out.

Further, if the subscriber selection switch 13 is pressed and then another subscriber selection switch 13 is pressed,
The specific storage areas include, for example, D13 and D14.
First, the number corresponding to D13 is read out, converted to a dial number, and sent out. When this sending is completed, the number corresponding to the subscriber selection switch 13 corresponding to the next D14 is read out and converted into a dial number. It is converted and sent.

When a plurality of subscriber selection switches 13 are pressed in this way, the corresponding subscriber selection numbers, for example, D13, D14, D15, are pressed.
... are stored in a specific storage area, and the corresponding numbers are read out and sent out.

As explained above, according to the present invention, the memory that stores the number information corresponding to the subscriber selection switch is provided with a specific storage area that stores the information read by the subscriber selection switch and/or the number information read by the number switch. The number information in this specific storage area is read out in the order in which it is stored, converted into a dial signal, and sent to the line.

Therefore, the dialing signal transmission operation by the subscriber selection switch and the number switch can be performed as desired. Therefore, when dialing to a subscriber with the same area number but a different telephone number after the area code on a business group telephone, etc., you can use the subscriber selection switch and number switch together to dial. can be simplified. Also,
Since the number switch can also be used, it has the effect of improving memory usage efficiency.
