After extracting the desired name or telephone number using the area number generation means (15) &t and the search means α, press the selection key and ``
It operates when the information Key indicating that the 'DIAL key' is closed is applied, and sequentially applies the numerical code of the station number corresponding to the selection key to the acoustic signal generating means (2) to transmit the station number. At the same time, it instructs the calling control means (3) the number of digits to be called, and causes it to send out a telephone number with the instructed number of digits after the area number has been sent.The specific operation will be described below.

The operation of dialing a telephone number in the automatic dialing device configured as described above will be explained.

First, in order to select the person you wish to call, the first three letters of the person's name are entered using the letter keys on the keyboard (6). These three input characters are stored in RAMIA and displayed on one display device (5)K. At this time, press the function key ' 5 on the keyboard (6).
When the ``EARCH key'' is closed, the search means α2 operates.The search means α2 takes in the three characters stored in RAMIA, controls the addressing means Q31, searches all RAM2A sequentially, and searches each RAM2A. The first three characters of the stored name are compared with the input three characters, and if there is a matching name, the addressing means [31
to be memorized. Then, specify RAM2A with the smallest address of the stored addresses, and write the name stored there.
AMIAK transfer and 1RAMIA to display device (
5) and display it.

If this name is not the name you want, click the keyboard
6) When the function key "PAGE key" is closed, the address designation means Q31 selects the RAM2 of the next address.
A is designated and similarly displayed on the display device (5). In this way, the desired name is searched and extracted, but if no matching name is found in the search, the characters rNOT FOUNDJ are displayed on the display device (5), and the name corresponding to the user is displayed. Let me know if it's not remembered.

After the desired name or telephone number is extracted through the above operations, when the selection key and the "DIAL key" are closed, the telephone number is dialed. At this time, if a telephone number is displayed, the call operation for that telephone number is started, and if a name is displayed, it is paired with RAM 2A in which the name is stored. One: RA
The telephone number is read out from the M2S, transferred to and stored in the RAM 15, and then displayed on the display device (5 performs the outgoing operation after being displayed.Next, we will explain each outgoing operation.
When only the "AL key" is closed, this is a local call, and the area number generating means α9 is the calling control means (3).
[By simply specifying the 7-digit transmission, the acoustic signal generation means (2
) K station number is not applied.

At this time, the transmission control means (3) sequentially reads the numerical code from the seventh digit to the lowest digit of the telephone number stored in the RAM 15, starting from the lowest digit.
) to send an acoustic signal. For example, if the extracted phone number is r321-456-78
90'', r456-7890 J is transmitted.

13) When closing the “DIAL key” after closing the “LD key” In this case, it is a local distance call, i.e.
In the case of a long-distance call, the area code generation means nsu family, area code "
1” is applied to the acoustic signal generating means (2) K,
0 Instructs the call control means (3) to make a 7-digit call. After the call control means (3) has finished calling the area number, the call control means (3) calls the last 7 digits of the telephone number stored in the RAM 1s. The numerical code from the first digit to the lowest digit is sequentially applied to the acoustic signal generating means (2) to transmit the signal.

For example, extracted phone number r321-456778
At 90J, ``12456-7890J'' is transmitted.

C) When the "DIAL key" is closed after closing the "OA key" In this case, the out/op area is also a call, that is, a call outside the area, and the area number ordering means a9 is the area number "
1” is applied to the acoustic signal generating means (2);
Instructs the transmission control means (3) to transmit 10 digits. The transmission control means (3) applies a numerical code sequentially from the 10th digit to the lowest digit of the telephone number stored in the RAM 15 to make a transmission.

For example, if the extracted phone number is r321-456-78
90J, rl-321-456-7890J is transmitted.

d) When the "OS key" is closed and then the "DIAL key" is closed. In this case, it is an over seas call, that is, an international call, and the area number generation means 09 generates the area number rOI IJ.
The numeric codes are sequentially applied to the acoustic signal generating means (2) to instruct the transmission control means (3) to transmit all digits.

For example, if the extracted phone number is r765-321-45
6-7890J, roll-765-321
-456-7890J is sent 0 θ) If you close the "CC key" and then close the "DIAL key" In this case, it is a local call using credit card, and the area number generation means a5 is the area number "0'' is applied to the acoustic signal generating means (2) K, and the transmission control means (3) instructs the transmission of 7 digits Vc.

For example, if the extracted phone number is r321-456-78
90J, "rO-456-7890" will be sent. f) "CC key", "LD key", "DIAL key"
In this case, it is a long distance call using credit, and the area number generation means α9 applies the numerical code of the area number "0" to the acoustic signal generation means (2), and the call control means (3) Instructs to dial 7 digits. That is, it is the same as the case of θ) above.

g) When the ``CC key'', ``OA key'', and ``DIAL key'' are closed in this order. In this case, it is a credit-based out-of-area call, and the area number generation means 05) generates the numeric code of the area number ``0''. The sound signal is applied to the acoustic signal generating means (2), and the transmission control means (3) instructs the transmission of 10 digits.

For example, if the extracted phone number is r321=456-78
At 90J, rO-321-456-7890J is transmitted.

h) When the call is closed using the "CC key", "OS key", or "DIALIAL key" In this case, it is a case of an international call using credit.
The station number generation means (151) sequentially applies the numeric code of the station number "01" to the acoustic signal generation means (2), and the transmission control means (3
) to send all digits.

For example, if the extracted phone number is r765-321-45
6-7890J, “0l-765-321-
456-7890J is transmitted.

As described above, by operating the selection key and closing the ``DIAL key'', the area number corresponding to the selection key created by the area number generation means α A call is made before the number is sent, and a telephone number having the number of digits specified by the area number generating means a5 is also called.

(e) Effect of the invention As mentioned above (according to the present invention, by operating the selection key,
Since a predetermined area number and a predetermined number of digits are automatically dialed, the automatic dialing device is easy to operate and use. In particular, portable automatic dialing devices are often used after moving to areas with different area codes or area codes, and in such cases, the effect becomes greater.
