It is used.

By the way, in the above-mentioned car telephone device having the calling function, if you forget the registered contents of the destination information or address number, you will not be able to retrieve the stored information and will not be able to output all the stored contents. There is a problem that the operation is complicated.

(Problems to be Solved by the Invention) As described above, conventional wireless telephone devices such as car telephone devices cannot retrieve the stored information when the initial letter or address number of the registered destination information is forgotten. There is a problem that it is not possible to search easily, it is necessary to output and confirm all the stored contents, and the operation is complicated.

The present invention is intended to solve the above-mentioned conventional problems,
To provide a wireless telephone device capable of searching for the destination information and its telephone number from part of the registered contents remaining in the user's memory even if the user forgets the initial letter or address number of the registered destination information. The purpose is to

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a registration input means for inputting a telephone number and other party information corresponding to the telephone number at the time of registration, and an input method using the registration input means. a storage means for storing the telephone number and destination information in correspondence with each other; and a search input means for inputting search information including a continuous part of the telephone number and the destination information corresponding to the telephone number when searching. a search means for searching the storage means for the telephone number including the search information and candidate information for the other party corresponding to the telephone number from the search information inputted by the search input means; a display means for displaying candidates for the telephone number and the destination information displayed by the display means; a selection means for selecting candidates for the telephone number and the destination information corresponding to the telephone number displayed by the display means; and calling means for making a call using the telephone number selected by the selection means.

(Function) In the present invention, by inputting search information of a number string or character string included in a pre-registered telephone number and the destination information corresponding to this telephone number by key input or voice input, a telephone number containing this search information can be searched. Candidates for number and destination information are searched and a call is made by selecting one.

Therefore, the user can easily search for the desired telephone number and destination information and make a call by inputting the search information of a number string or character string that is part of the information that remains in the memory. can.

The liquid crystal display 452 includes a number display section for one or several digits, a display section for each function, and the like.

The LCD driver 454 drives the liquid crystal display 452 under the control of the control unit 418 to perform a predetermined display.

The key part 430 has number keys "0" to "9""*","
#”, rSNDJ, rsTOJ, “ENDJ, rRCL
J, rFNCJ, rcLRJ, “EMR”, “MUTE
”, consists of keypads such as rTONEJ function keys,
When the keypad is pressed, this is recognized by the control unit 418.

Next, the operation of searching for a stored telephone number in the thus configured car telephone device will be explained with reference to the flowchart of FIG. Here, the telephone numbers of a plurality of parties to be called and the IJ hand information corresponding to these telephone numbers are stored in the telephone number storage memory 3 of the memory dial section 350.
50C1 It is assumed that the other party information storage memory 350d stores the information in advance.

First, the user selects “rFNCl, #” in key part 430.
When "#" is entered, the stored telephone number search mode is set (step 301). At this time, rseachJ is displayed on the liquid crystal display 452 (
Step 302).

Next, the user inputs a number string or character string that is search information that remains in his/her memory using the key part 430 (step 303). For example, when entering this search information, if the phone number you want to search is "03-254-XXXX",
If "254" remains in the user's memory, the user inputs this continuous number string "254".The input search information is also displayed on the liquid crystal display 452.

Thereafter, when "rRCLJ" is entered in the key section 430, the search section 350b of the memory dial section 350 searches the telephone number storage memory 350c or the destination information storage memory 350d, and searches for the telephone number and other information containing the above-mentioned search information. Candidates for the destination information are searched (Step 3)
04). For example, if the search information is “254” as described above, “0254-XXX-1111” or “03-
Candidates containing a 254'' number string, such as XXX-2543', are searched.

Then, if there is a candidate that includes the search information (Ste Nobu 30
5) One of the candidates is displayed on the liquid crystal display section 452 (step 306).

The user visually checks the display on the liquid crystal display 452 and selects the key part 4.
The display of candidates is advanced by inputting the "#" key at 30, and the candidate display is returned by inputting the "*" key to confirm the desired candidate (step 307).

When the user confirms the desired telephone number or other party's information, the user inputs the key ``5ENDJ'' in the key section 430 to end the search mode and make a call using this telephone number. (Step 308).

In addition, after entering the above search information,
In step 309, if a candidate including the search information cannot be found, rNothing J is displayed on the liquid crystal display 452 (step 309).

Also, during each of the above-mentioned operations, the key part 430 displays "rFNcJ
When the key input of "rCLRJ" is performed, the search mode is ended.

Therefore, in this embodiment, by inputting a pre-stored telephone number and a number string or character string included in the destination information corresponding to this telephone number as search information, the desired telephone number and destination can be searched. Information can be searched.

As a result, even if the user has forgotten the initials of the recipient's phone number or the first letter of the phone number, the desired phone number can be easily entered by entering the number string or character string that remains in the user's memory. You can search for and the other party's (+'j) information.

In the above-described embodiment, the search information is entered by key input on the key section 430, but the search information can be entered by voice and the voice is transferred to the voice recognition LSI 350a of the memory dial section 350. It may be configured such that the telephone number and other party's information are searched using the recognition information as search information.

[Effects of the Invention] As explained above, the wireless telephone device of the present invention allows search information of a number string or character string included in a pre-registered telephone number and the destination information corresponding to this telephone number to be input by key or voice. By doing so, candidates for telephone numbers and destination information including this search information are searched, and by selecting them, a call is made. This allows the user to easily search for the desired phone number and destination information and make a call by inputting the search information of a number string or character string that is part of the information that remains in the memory. be able to.
