Abstract

PURPOSE:To easily attain a re-dialing to an opposite whom a dialing has been placed previously by storing dialed telephone numbers in a past and displaying them on a display device with a retrieval button. CONSTITUTION:A microcomputer 6 stores all of the telephone numbers in the past selected with a dial button 1 on a memory 5. By the depression of a retrieval button 3 to perform the re-dialing, the telephone numbers dialed in the past are read out in order from the latest one from the memory 5, being displayed on a display device 7. When an objected telephone number is displayed, the telephone number, by the depression of a dial button 4, is sent out to a line 10 by a dial outgoing circuit 8.

Description

[Detailed description of the invention] (Industrial application field) Misfire! Man &: I: Microcomputer k P3 Under the control of this microcomputer, normal transmission,
The present invention relates to a multifunctional telephone that can display a calling telephone number, make a re-call, etc. in addition to making a telephone call.

(Prior art) Functions such as speed dialing, displaying telephone numbers, re-dialing, etc. simplify dialing operations and reduce mistakes in telephone numbers, making them convenient, so various types of multi-functional telephones have come into practical use. It is served to

The re-call function on conventional multi-function telephones is limited to the operation of the re-call button when the telephone has been dialed in the past and only returns the most recent telephone number. It is automatically sent to the telephone line.

(Problems to be Solved by the Invention) However, the re-transmission function described above has a drawback in that it cannot be used in the following cases.

(1) When you call A, after t, you call B and again pay 11L to the person.

(2) When you call A, then call B and O and talk to A or BVct again.

The above case occurs frequently in daily telephone operations and shows the limitations of multifunctional telephones.

The purpose of the present invention is to memorize nine telephone numbers dialed in the past;
It is an object of the present invention to provide a multifunctional telephone that can solve the above-mentioned drawbacks by allowing the operator to confirm the selection and then automatically make a call.

(Ninth Means for Solving the Problems) In order to achieve the above object, the multifunction telephone according to the present invention displays dialed telephone numbers on a display under the control of a microcomputer. A memory for storing n* telephone numbers, a search operation section for sending out a search signal, and a calling operation section for sending out a call signal are provided, and the microcomputer receives the search signal. At this time, the latest stored telephone number is read from the memory and displayed on the display, and thereafter, every time a search signal is received, all telephone numbers are sequentially read out, and when the outgoing signal is received at 9, the displayed telephone number is called. It is being intercepted so that it can be controlled.

(Example) Next, drawings about the present invention? Refer to and explain.

FIG. 1 is a block diagram showing one embodiment of the present invention.

The microcomputer 6 detects button press information from the dial button 1, the re-send button 2, the search button 3 which is a search operation section, and the call button 4 which is a call operation section.
Ru.

The microcomputer 6 stores the dialed telephone number and other necessary information in the memory 5, and also sends display data to the display 7 to display the call number 9'1. Then, the dial data is sent to the dial transmission circuit 8, and the line end 10 is caused to send out a dial selection signal.

Is call circuit 9 dial circuit 8? ] - is connected to the line end 10 through the terminal 10, and it is possible to talk to the other party.

The microcomputer 6 has a storage program that stores the dialed I11 number in the memory 5, a storage program that detects button press information, and in the case of press information from the search button 3, reads the stored telephone number from the memory 5 and displays it on the display 7. an accumulation program that reads and displays all the next phone numbers when the search button 3 is pressed again and again;
In the case of press information from the call button 4, there is a built-in storage program for sending the displayed telephone number to the dialing circuit 8 and other functions.

We will explain each case of story operation.

After AKt has finished speaking (A may be busy at this time)
, If you want to call A again, you can use the conventional redial function. In other words, by pressing the re-call button 2, the microprocessor 6 selects the latest phone number among the phone numbers dialed in the past. υ is read from the memory 5, sent as display data to the display 7, and displayed on the telephone number, and also sends dial data to the dial circuit 8 as a dial selection signal? It is sent out to the line end 1o.

Next, call A, and then call B. At this time, A and B
(may be busy), and if you want to talk about AlC11, first press the search button 3 all once. At this time, the microprocessor 6 is dialed in the past and 7?1. i
The newest telephone number (B's telephone number) among the t telephone numbers is read out from the memory 5 and sent to the display 7 as display data to be displayed.

When the search button 3 is pressed once more (that is, twice), the microcomputer 6 reads out the second new telephone number (the person's telephone number) from the memory 5 among the telephone numbers dialed in the past, and the display 7 to be displayed as display data. By pressing the call button 4 here, the microcomputer 6 sends the currently displayed telephone number (A
[telephone number] t The dial circuit 8 is controlled to send it to the line end IO as a dial selection signal.

Therefore, by fully pressing the search button 3, the searched past telephone number will be displayed on the display 7, and by pressing the call button 4, the telephone number displayed on the display 7 can be dialed. Therefore, after calling A, B, and O (A, B.

C may be busy.) To call O again, press the search button 3'' once, press the call button 4, or press the re-call button 2.
If you want to call B again, press the search button 3 twice and then press the call button 4. If you want to call A again, press the search button 3 three times and press the call button 4. You can dial by pressing .

The problem here is how many phone numbers that have been dialed in the past should be memorized, but considering human memory (how many times the phone was previously dialed), about 0 is sufficient.

This function can also be used as a substitute for the speed dial function.

Instead of pressing the search button 3 multiple times, use the dial button 1 (1) ~ times and press the # button or the * button to search for one of the phone numbers displayed on the display. Displaying all of the previous telephone number or the next telephone number is intended to improve the search performance i4 and is included in the present invention.

(Effects of the Invention) As explained in detail above, the present invention memorizes nine telephone numbers dialed in the past and displays them on the display using the search button, thereby resuming previous calls that were not possible with the re-call function. Being able to make a call to the other party with a simple button press has a positive effect.
