Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a telephone with a redial function.

Conventional technology Traditionally, multi-function phones have a redial function that stores the previous phone number in its internal memory, and if the person you dialed is busy, you can dial again by pressing the - button. There was something in store. This function allows you to dial as many times as you like with one-touch operations until you can call the other party.

Problems to be Solved by the Invention However, in conventional telephones such as those mentioned above, the internal memory is rewritten with the newly transmitted telephone number after going off-hook, so the previously transmitted telephone number is not stored. Although it was possible to redial the person who had just called, it was not possible to redial the person who had called earlier with a single touch.

In other words, when one party is busy, you often call another party, complete your business, and then dial the former party again. Since the number is not memorized, the user has to press the dial key again to dial, and the redial function, which allows dialing with one-touch operation, cannot be used.

Means for Solving the Problems In order to solve the above problems, the telephone set of the present invention includes a first telephone number storage means for storing telephone number information corresponding to the latest dialing signal sent into the telephone line. and a second telephone number storage means for storing telephone number information in advance;
a specifying means for specifying a storage area in the second telephone number storage means; and a specifying means for specifying the storage content of the first telephone number storage means in the second telephone number storage means specified by the specifying means. a transfer means for transferring the telephone number information to a storage area therein, a means for reading the telephone number information stored in the first telephone number storage means and the second telephone number storage means, and transmitting a dial signal corresponding thereto into the telephone line; Be prepared.

Function: With this configuration, not only the latest telephone number information but also the number called earlier can be stored, so that it can be called and dialed any number of times in the future.

Next, the case of making a phone call will be explained.

Switch the mode selector switch 10 to the rSJ side. The input terminal P5 of the control means 13 becomes the logic level rL,
Enters call mode. When the handset 6 is picked up, the hook switch 2 is turned on and the telephone line is closed.
It is connected to a telephone line via a line interface circuit 3. To send out a dial, just press the dial button 7. Dial data is output from the output terminal P1 of the control means 13, converted into a dial signal by the dial sending means 4, and sent to the telephone line 1. In addition, when transmitting a telephone number stored in advance in the storage means 9,
A station (for example, "5") is designated using the station designation button 8. Then, the control means 13 selects "Station 5" from the preset dial area 9b of the storage means.
, calls the corresponding dial data and outputs the output terminal PL.
Dial data is output from the dial transmitting means 4, which converts it into a dial signal and transmits it to the telephone line 1. When connected to the other party, a conversation can be made using the transmitter/receiver circuit 5 and the handset 6. Further, the latest sent telephone number is stored in the storage means 9 for redial data. If the called party is busy, wait a while, go off-hook again, and press the redial button.Then, the control means 13 calls the redial data from the redial area 9a of the storage means 9, and outputs it to the output terminal. P1
Dial data is output from the dial transmitting means 4, which converts it into a dial signal and transmits it to the telephone line 1. When connected to the other party, a conversation can be made using the transmitter/receiver circuit 5 and the handset 6.

Next, an explanation will be given of the operation when a telephone number once dialed is stored in the preset dial area of the storage means 9.
