BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone telephone number search function and a memory function which are generally used. In particular, the telephone number stored in the memory of the telephone and the telephone number of the counterpart to which the user wants to talk correspond to the function keys of the operation switch. Pressing (#) allows you to make a call without dialing the entire number.

Conventional apparatus controls the handset, a bell section for informing the user of a received signal from the telephone, a telephone number dial, a memory section for storing the telephone number, a liquid crystal display (hereinafter referred to as an LCD), and each section. It was composed of micom.

Such a conventional apparatus stores a frequently used telephone number in a memory unit, reads a telephone number stored in the memory unit when the user wants to make a call, and confirms whether the read telephone number is a telephone number of the counterpart to be called and starts it. When the button is pressed, the signal is signaled to the other party to talk through the telephone exchange.

However, the conventional apparatus configured as described above cannot confirm whether or not the telephone number of the party to be called is stored in the memory unit, and even if the telephone number is stored in the memory unit, it is not easy to find the telephone number. There was a problem that it was not easy to delete the saved phone number.

An object of the present invention is to solve the above problems, in particular, when the user presses the telephone number of the counterpart to the user through the operation switch, the telephone number stored in the memory unit is pressed by the user under the control of the microcomputer Prints a phone number similar to or identical to the number on the LCD. If the phone number of the party you want to talk with is the same as the phone number printed on the LCD, pressing the function key (#) on the operation switch allows you to make a call automatically without pressing all the 7 to 8 digits. On the other hand, if the user does not have the same phone number as the other party's phone number and presses all 7-8 digits, the microcomputer recognizes that the user does not have 7-8 digits and saves it in the memory automatically. The present invention provides an automatic telephone number retrieval apparatus and a control method thereof.

In order to achieve the above problems, the present invention provides an automatic telephone number searching device and a control method thereof. A memory unit for storing a telephone number; An operation switch composed of a plurality of character keys, a number key and a function key; A microcomputer that outputs a phone number identical to or similar to a phone number of a counterpart to be called by a phone number held by the user and stored in the memory unit; The technical configuration is characterized by including a display unit for showing the user to the telephone number output from the microcomputer.

The automatic telephone number retrieval apparatus and its control method of the present invention are operated to automatically make a phone call without pressing all of the counterpart's telephone number, so that the user can feel convenience in an environmental aspect.

Hereinafter, with reference to the accompanying drawings for an embodiment according to the technical idea of the present invention automatic phone number search device and the control method configured as described above are as follows.

Example

As shown in FIG. 1, the signal output terminal of the telephone 1 and the signal output terminal of the operation switch 4 are connected to the signal input terminal of the microcomputer 5, and the signal output terminal of the microcomputer 5 is connected to the display section 3 of the display unit 3. In this embodiment, the memory unit 2 and the microcomputer 5 are connected to each other so as to be able to input / output mutually.

As shown in FIG. 2, a first step (S1) of checking and determining whether a tone signal is present; A second step (S2) of returning to a start state when it is not a tone signal in the first step (S1), and inputting an N-th digit telephone number of a counterpart to be called; A third step (S3) of determining whether the N-digit telephone number input is completed in the second step (S2); If the input of the N-digit phone number is not completed in the third step (S3), return to the second step (S2) and retry the input, and the input of the N-digit phone number is completed in the third step (S3). A fourth step (S4) of reading a list of telephone numbers stored in a memory and detecting and outputting a telephone number similar to or identical to a telephone number sequentially input by a user on the LCD; A fifth step (S5) of judging whether the user pressed the function key (#) of the operation switch by comparing the telephone number displayed on the LCD with the telephone number of the counterpart in the fourth step (S4); A sixth step (S6) of automatically dialing a telephone number displayed on the LCD when the user presses a function key (#) of the operation switch in the fifth step (S5); A seventh step (S7) of checking whether the number of digits of the telephone number input by the user is tenth if the function key (#) of the operation switch is not pressed in the fifth step (S5); An eighth step (S8) of returning to the second step (S2) by adding 1 to the Nth digit if the telephone number input by the user in the seventh step (S7) is not the tenth digit; If the telephone number input by the user in the seventh step (S7) is the tenth digit, the present invention comprises a ninth step (S9) which is stored in the memory unit and sends a signal to the exchange to make a call with the other party. .

Hereinafter, the present embodiment configured as described above will be described in detail.

First, when the user presses the first digit telephone number of the counterpart, for example: 123-4567, the telephone number starting with 1 stored in the memory unit is displayed on the LCD of the display unit. If the phone number displayed on the LCD of the display unit is the same as the phone number of the other party you want to call, when the user presses the function key (#) on the operation switch, the call is automatically made without pressing the phone number of the other party. You can do it. However, if the telephone number displayed on the LCD of the display unit does not match the telephone number of the counterpart, the user continues to press the telephone number. Therefore, each time you press the phone number one more time, the same or same phone number as that of the other party you want to talk on is displayed on the LCD of the display unit. If the phone number is not displayed on the LCD until the user presses the phone number of the other party to call, the phone number that the user presses is automatically stored in the memory unit under the control of the microcomputer.

As described above, the automatic telephone number search apparatus of the present invention and the control method thereof, in particular, the telephone number stored in the memory unit before the telephone number is completely pressed is output on the LCD and the counterpart of the counterpart who wants to talk with the outputted telephone number. If the phone number is the same, pressing the function key (#) of the operation switch automatically makes a call, so it is convenient in terms of the environment of the user who uses the phone and can save a large amount of phone numbers. .
