The number key "1" means "あ, い, う, え, お", the number key "2" means "か, き, く, け, こ", and the number key "3" means "さ, し, す, せ". , そ, 키 4, た, ち, つ, て, と, 키 5, な, に, ぬ, ね, の, 키 6, は, ひ, ふ, へ, ほ ”, the number key“ 7 ”is“ ま, み, む, め, も ”, the number key“ 8 ”is“ や, ゆ, よ, ″, ° ”and the number key“ 9 ”is "わ, を, ん, ..., 一" is assigned to "ら, り, る, れ, ろ" and the numeric key "0", respectively. Thus, for example, to enter the word 'え ん と つ', press the number key '1' four times (enter 'え'), press the number key '0' three times (enter 'ん'), and enter the number key ' Press “4” five times (enter 'と') and press the numeric key '4' three times (enter 'つ').

However, in the conventional character input method, since a corresponding key needs to be pressed several times in order to input a predetermined character, the character input time becomes long and typos are easy to occur. Furthermore, a character that requires a large number of presses (for example, in the case of え ん と つ, え and と must press the numeric key `` 1 '' four times and the numeric key `` 4 '' five times, respectively). Is even more so.

Accordingly, in order to solve the above problems, an object of the present invention is to provide a character input method that can be quickly and easily input by using a function key a character that requires a large number of presses among the characters assigned to each key of the portable terminal. do.

(First embodiment)

In the Japanese input method according to the first embodiment of the present invention, a long press of a corresponding key when inputting a character requiring a large number of pressing times enables easy input.

Referring to Table 1 in more detail as follows.

Numeric keys Assigned Characters (Times) 1 2 3 4 5  Long press Short press again   One あ, い, う, え, お     え     お   2 か, き, く, け, こ     け     こ   3 さ, し, す, せ, そ     せ     そ   4 た, ち, つ, て, と     て     と   5 な, に, ぬ, ね, の     ね     の   6 は, ひ, ふ, へ, ほ     へ     ほ   7 ま, み, む, め, も     め     も   8 や, ゆ, よ, ″, °     ″     °   9 ら, り, る, れ, ろ     れ     ろ   0 わ, を, ん, ·, 一     ·     一

As shown in Table 1, for each numeric key, the fourth assigned letter can be entered by pressing and holding the corresponding key, and the fifth assigned letter can be entered by pressing and holding the key for a short time again. For example, in order to enter the character "あ え", it is inputted by pressing the numeric key "1" once (enter "あ") and then pressing and holding the numeric key "1" (enter "É"). You can enter 2 circuits less times than あ 'input (1 time) +' え 'input (4 times) = 5 times. In addition, to enter the letter 'え お', enter the letter 'え' by pressing and holding the number key '1' long (enter 'え'), then press and hold the number key '1' and shortly pressing it again (enter 'お'). You can enter 3 times less than 'え' input (4 times) + 'お' input (5 times) = 9 times).

Therefore, the character can be input quickly and easily by using fewer keys than in the related art. This method is briefly described in FIG.

As shown in the figure, after pressing and holding the numeric key to which the character to be entered belongs (S10), if not pressed again (S20), the fourth character assigned to the corresponding numeric key is input (S30). For example, when the numeric key "1" is pressed and held, the letter "え" is input.

In addition, if the corresponding key is briefly pressed again in step S20, the fifth allocated character is input (S40). For example, press and hold the numeric key "1", and then briefly press the character "お".

(Second embodiment)

In the Japanese input method according to the second embodiment of the present invention, a function key can be input quickly and easily when inputting a character requiring a large number of pressing times.

Referring to Table 2 in more detail as follows.

Numeric keys Assigned Characters (Times) 1 2 3 4 5 1 function key 2 function keys   One あ, い, う, え, お     え     お   2 か, き, く, け, こ     け     こ   3 さ, し, す, せ, そ     せ     そ   4 た, ち, つ, て, と     て     と   5 な, に, ぬ, ね, の     ね     の   6 は, ひ, ふ, へ, ほ     へ     ほ   7 ま, み, む, め, も     め     も   8 や, ゆ, よ, ″, °     ″     °   9 ら, り, る, れ, ろ     れ     ろ   0 わ, を, ん, ·, 一     ·     一

In order to input a character requiring a large number of pressing times, for example, a letter え, お assigned to the numeric key `` 1 '', the character input time must be pressed four or five times, respectively. Lengthened However, as shown in Table 2, inputting the single character 'え' or '오' using the function key (preferably, the function key "*") can significantly reduce the character input time. That is, if the function key "*" is pressed once after pressing the numeric key "1" (that is, in the "あ" state), the character "あ" is converted into "え" and inputted. Then, when the function key "*" is pressed twice (that is, in the 'あ' state), the letter 'あ' is converted into 'お' and inputted.

Therefore, it is possible to quickly and easily input a character requiring a large number of pressing times using a key of fewer times than in the related art. This method is briefly described in FIG.

As shown in the figure, the user presses the numeric key to which the character to be entered belongs to (S10 '). For example, in order to input the letter 'え', the numeric key (ie, the number key '1') to which 'え' belongs is pressed.

Next, the fourth or fifth allocated characters are input according to the number of times the function key is pressed (S20 ').

If the function key "*" is pressed once in step S20 ', the fourth assigned character is entered (S30'), and if the function key "*" is pressed twice, the fifth assigned character is entered ( S40 ').

In addition to the function key "*", the function key "#" may also be used for the following purposes.

As shown in Fig. 3, switching between hiragana (lowercase) and katakana (uppercase) in Japanese and switching between upper and lower case in English can be facilitated. In other words, to enter Hiragana, you can switch to Kadakana by pressing the function key "#" without having to enter a separate menu folder. Of course, pressing the function key "#" again can be switched to the original hiragana mode.

In addition, while inputting the hiragana or katakana, long press the function key "#" can be automatically switched to the lowercase English mode. In this mode, the function key "#" is briefly pressed again to switch to the English capital letter mode. Of course, pressing the function key "#" again can be switched to the original English lowercase mode. Here, instead of the hiragana <-> katakana, English lowercase <-> English capital letters, a) Korean <-> English lowercase letters, numbers <-> symbols, b) Hiragana <-> katakana, English uppercase <-> English Lowercase letters, c) Takum <-> halftone, digits <-> symbols, d) Chinese <-> English lowercase letters, digits <-> and the like can be switched using the function key "#". That is, one key (here "#") can be given a function for switching to various modes.

In this way, the function key "#" is shortly switched between Hiragana and Kadakana or between English lowercase and uppercase letters, and the function key "#" is long to switch between the hiragana (katakana) and lowercase English letters (uppercase). Can be. This makes it possible to easily input without using a menu key for switching the language and switching between upper and lower case letters.

As described above, according to the present invention, a character requiring a large number of pressing times among characters assigned to a predetermined key (for example, the fourth and fifth characters when five characters are assigned to each key) is selected. By pressing and holding or using the function keys can be entered faster and easier than before. In addition, although the present invention has been described as a portable terminal by way of example, those skilled in the art will appreciate that it can be used in any device in which a predetermined number of characters are assigned to each key, respectively. In addition, the Japanese may be used, for example, when inputting characters of other languages (for example, Russian, English, etc.).

While the invention has been particularly shown and described with reference to preferred embodiments, it will be apparent to those skilled in the art that other changes may be made in form and detail of the above-described embodiments without departing from the spirit and scope of the invention. will be.
