Abstract

PURPOSE:To simplify the retrieval of numbers by keeping a dial number at the time of transmission. CONSTITUTION:The dial number inputted first is held in 21 of a circulation queue, and numbers are held in succession in the direction, toward 22. When the circulation queue is filled and advanced to 23, the next dial number is held in location 21 and the number formerly held is rewritten. Thus, a dial retrieval section retrieves dial numbers in the storage section by means of a retrieval F key 16 or R key 17. The input number by a dial key 13 is displayed on a liquid crystal display section 14 and transmitted by a transmission key 15. The number is held in the dial storage section. When the storage section becomes full, the older number is rewritten to new one. In retrieving numbers, some leading digits are displayed on the display section 14, and the dial retrieval section retrieves the stored number in any direction by depressing the keys 16 or 17, displaying all numbers on the display section 14 in succession. The entire section can be displayed by several heading digits, the numbers are stored the transmission, simplifying the retrieval.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device with a number search function.

[0002]

2. Description of the Related Art Conventionally, in this type of telephone device, a frequently used telephone number is registered in advance in a speed dial or the like, and by pressing the corresponding speed key, the destination of the dial number can be automatically dialed. It is like this.

[0003]

However, in the above-mentioned conventional telephone device, it is necessary to register the telephone number of the other party in advance, and the registered telephone number and the speed dial number can be reliably associated with each other. Without it, there was a problem of calling the wrong person.

The present invention solves such a conventional problem, and it is not necessary to register the telephone number of the other party in advance, and moreover, a necessary telephone number can be easily found from a plurality of telephone numbers. It is an object of the present invention to provide a telephone device with an excellent number search function that can be used.

[0005]

In order to achieve the above object, the present invention provides dial storage means for storing dial numbers input at the time of transmission in a circular queue format, and dial numbers stored in the dial storage means. , A dial search means for performing a search by inputting a fixed number of digits in the leading part and displaying it on the display unit.

[0006]

Therefore, according to the present invention, since the dialed number is saved at the time of transmission, it is not necessary to register the telephone number in advance, and the whole number of the telephone number can be simply input by inputting the leading digits of the telephone number. Is displayed, the effect is that the necessary telephone number can be easily found.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, reference numeral 1 is a station line, 2 is a communication circuit connected to the station line 1, and 3 is a control circuit connected to the communication circuit 2. A transmitter 4, a receiver 5, a push button switch 6 and the like are connected to the call circuit 2, and a function button switch 7, a display circuit 8, a dial storage unit 9, a dial search unit 10 and the like are connected to the control circuit 3. Has been done. FIG. 2 shows the appearance of the telephone device. Reference numeral 11 is a housing, 12 is a handset, 13 is a dial key, 14 is a liquid crystal display, 15 is a transmission key, 16 is a search F key for searching forward, 17 is a search R key for searching backward, and 18 is cancel. Is the key.

Next, the operation of the above embodiment will be described.
Since the incoming and outgoing operations are the same as those of a normal telephone device, only the operation of the main part of the present invention will be described below. When making a call to the other party, first dial key 13
Press the destination number in order from the beginning. As a result, the numbers are sequentially displayed on the liquid crystal display unit 14, and after confirming that the numbers are correct, the transmission key 15 is pressed to automatically dial the destination. At this time, the dial number is simultaneously stored in the dial storage unit 9 in the circular queue format.

FIG. 3 shows a circular queue format data structure in the dial storage unit 9. Initially, no dialed numbers are stored in the circular queue. The first dialed number is stored in position 21 of the circular queue, and then sequentially in the direction of arrow 22. When the circular queue is filled and reaches position 23, the next dialed number is stored in the first position 21 and the previously stored number is rewritten. That is, the old number is rewritten and stored when the new number comes to that position. The dial search unit 10 starts the search for the dial number stored in the storage unit 9 in this manner by pressing the search F key 16 or the search R key 17.

Next, a search method will be described. Now, assume that the first number is stored at position 24 in FIG. First, the leading four digits of the number to be searched are input from the dial key 13 and displayed on the liquid crystal display unit 14. Then, when the search F key 16 is pressed, the search is performed from the position 24 in the direction of the arrow 25, and when the search R key 17 is pressed, the search is performed in the direction of the arrow 26 from the position 24, which is the same as the input first four digits. All telephone numbers having numbers are sequentially displayed on the liquid crystal display unit 14. If there is no corresponding telephone number, the cancel key 18 is pressed to return the liquid crystal display unit 14 to the initial state.

As described above, according to the above-described embodiment, when making a call in a normal time, when the number is input by the dial key 13, the number is displayed on the liquid crystal display unit 14, and the transmission key 15 is pressed to perform the transmission. At the same time, the transmitted number is stored in the dial storage unit 9. When the dial storage unit 9 becomes full, the old storage number is rewritten with a new number and stored. When the telephone is used by an individual, the telephone number to be dialed tends to be very limited, so that the dial storage unit 9 can be realized by a small amount of memory. Also,
To search for a dial number, the first few digits of the number to be searched for are displayed on the liquid crystal display unit 14, and the search F key 16 or the search R key 17 is pressed.
It is possible to search the dial numbers stored in the dial storage unit 9 in any direction and display all the numbers in order on the liquid crystal display unit.

[0012]

As is apparent from the above embodiment, the present invention does not require the telephone number to be registered in advance because the dialed number is stored at the time of transmission, and only needs to enter the leading digits of the telephone. Will display the entire phone number, so
You can easily find the phone number you need.
