The registration items (telephone numbers) belonging to the range of the skip registration number number (N) corresponding to the value n are searched one by one in the order of the registration numbers (step 904), and the searched telephone numbers are retrieved from the telephone directory registration table 12b. The data is read out and displayed on the LCD 11a (step 905).

Thereafter, the key operation mode detecting unit 601 monitors whether or not the call key 10a among the various function keys on the operation unit 10 has been pressed (step 906). Here, when the call key 10a is not pressed (step 90)
6NO), returning to the processing after step 902 to continue monitoring the pressing of the next quick dial keys P1, P2, P3. And quick dial keys P1, P
2 and P3, every time the P1 key is pressed, the telephone numbers in the telephone directory registration table 12b are searched one by one by the above-described method in the order of the registration numbers, and are searched for in the LCD 11a.
And continue searching while checking.

During this time, for example, when the P3 key is pressed (step 910 YES), the search operation control unit 604
Means that the telephone number in the telephone directory registration table 12b which has been searched in the order of the registration number has been skipped, and thereafter, the skipping corresponding to the count value n of the skip number search counter n in the telephone directory registration table 12b is performed. The registered items (telephone numbers) belonging to the range of the number of registered numbers (N) are searched one by one in the reverse order of the pressing of the P1 key (step 911), and the searched telephone numbers are retrieved from the telephone directory registration table 12b. The data is read out and displayed on the LCD 11a (step 905).

On the other hand, if the P2 key is pressed during the key press monitoring (YES in step 920), the search operation control unit 604 determines the number of skip registration numbers corresponding to the count value n of the skip number search counter n until then. A search for each registered item (telephone number) belonging to the range of (N) one by one in the order of the registration number or in the reverse order, and thereafter, for example, from the registration number 20 to the registration number 30, A search is made for a telephone number corresponding to the previous registration number by the preset skip registration number (N).

More specifically, the search operation control unit 604
When the key is pressed, "1" is added to the skip number search counter n (step 921), and then it is determined whether or not the value of the skip number search counter n is "20" or more (step 921). 922). Here, if the value of the skip number search counter n is “20” or more (step 922 YES),
The value of the skip number search counter n is changed to "n = 1" (step 923).

On the other hand, when the value of the skip number search counter n is smaller than "20" (step 922 NO),
[(N × 10) +1] is calculated and the telephone directory registration table 1
A telephone number registered corresponding to the registration number corresponding to the calculated value in 2b is searched (step 924), and the searched telephone number is read from the telephone directory registration table 12b and displayed on the LCD 11a (step 924). 905).

By the processing of the above steps 920 to 924, for example, one key using the P1 key or the P3 key
After searching for the telephone number of “Kato” in the registration number “3” in the telephone directory registration table 12b by searching the registration number in order of each item (step 904) or searching the registration number in reverse order (step 911), the P2 key is pressed. In this case, the telephone number of the other party registered for the ((1 × 10) + 1 = 11) registration number calculated based on the value of the skip number search counter n (n = 1) at this time Move to search. Further, by operating the P2 key, the above-described skipping search of the skipped number “10” is continued, and after the P2 key is operated 19 times, [(19 × 10) +1
= 191], and the P2 key is further pressed while searching for the telephone number corresponding to the registered number, the jump number search counter n becomes (n = 20) and is incremented to (n = 0). (Step 923), [(n × 10)
+ 1 = 1], that is, the telephone number of "Aoyama" at the head of the telephone directory registration table 12b is searched.

After the search by the quick dial keys P1, P2, and P3 in the order of the registration numbers, the search in the reverse order of the registration numbers, or the skip search by the number of the registration numbers (N) as described above, If the call key 10a is pressed (YES in step 906), the calling operation control unit 603 in the control unit 6 performs a calling operation based on the telephone number currently displayed on the LCD 11a as a search result of the telephone directory. (Step 907) After the connection with the other party, the process proceeds to a call operation (Step 908).

As described above, the quick dial key P
1, P2 and P3 function as the original quick dial keys by a short press of, for example, not exceeding 2 seconds, and a key for starting a telephone directory search mode by a long press of more than 2 seconds. Also serves as a function. In the telephone directory search mode, for example, P
One key can be used as a forward search key, the P3 key can be used as a reverse search key, and the P2 key can be used as a search key skipping a plurality of items.

By providing a high-speed search key equivalent to P2, a search that could previously be performed only one item at a time can now be performed by skipping a plurality of items. Even in the case of a telephone directory in which a number is registered, it is possible to display the target telephone number very quickly by the high-speed search.

Further, according to the present invention, a function of immediately calling by using the telephone number by pressing the call key 10a while the searched telephone number is being displayed is supported. The search can also contribute to improving the key operability at the time of calling or shortening the calling operation time.

In the above embodiment, an example has been described in which the quick dial calling mode or the telephone directory search mode is set according to the pressing time of the quick dial keys P1, P2, P3. The number of times the key is pressed may be monitored, and the operation modes may be set depending on whether the key has been pressed once or a plurality of times.

Although the telephone directory is taken as an example of a search target, the present invention can be applied to a search of information item registration means in which various information items are registered.

In each of the high-speed search shown in FIG. 7 and its modification (FIG. 9), the number of telephone numbers that can be registered, the number of lines to be skipped, and the number of registered numbers (N) can be set arbitrarily. In addition, it can be configured such that the skipping direction can be made both forward and reverse. Further, in the modified example shown in FIG. 9, since a jump is made to the registration number of [(n × 10) +1], for example, in accordance with the operation number n of the P2 key for skip search, the registration number of the jump destination is fixed. (11th, 21st, ...), but if necessary,
A modification can be made so that the registration number being searched at the present time jumps to the registration number of [(n × 10) +1]. Further, the present invention is not limited to the PHS, but may be applied to other mobile radio terminals, for example, PDC (Personal Digital Cellula).
It is needless to say that the present invention can also be applied to r) and pager.
