20: keypad

The present invention relates to a character input method, and more particularly, to a keypad of a portable terminal and a Japanese input method using the same to reduce the number of key inputs when inputting a Japanese language using the keypad of the portable terminal.

In general, a home telephone or a portable terminal, ie, a mobile phone, a portable computer, and a PDA, inputs a desired number using a numeric keypad arranged with a minimum number of keys. This is a general numeric keypad in which 10 keys are arranged in order from 0 to 9, and a total of 12 keypads are installed with # and *, which are keys used as two separate function keys, arranged on both sides of 0.

Recently, according to the development of mobile communication, a terminal equipped with the numeric keypad arranged as described above has a function of an electronic organizer or a function of sending and receiving Korean text messages, and in particular, it is possible to connect to the Internet using mobile communication. Therefore, it is possible to send mail or chat by connecting to the Internet from the terminal. Accordingly, since inputting Hangul from the numeric keypad installed in the terminal is becoming a main function of the terminal, terminal manufacturers have introduced a more convenient Hangul key input method.

On the other hand, Japanese countries that mainly use Japanese rather than Korean input have a key arrangement structure of a keypad so that an alphabet can be easily input.

1 is an exemplary view showing a key arrangement structure of a conventional portable terminal.

Referring to FIG. 1, the keypad 10 is assigned a character for Japanese input to numeric keys '1 to 0' and special keys '*' and '#'. At this time, a plurality of characters are assigned to one numeric key and a special key. Thus, the plurality of assigned characters are converted and keyed in accordance with successive keystrokes of the numeric keys.

For example, if you want to input 'ko', you have to enter the number key '1' assigned to the letter 'ka' five times in a row. That is, the characters converted according to the number of inputs of the numeric key '1' are as follows.

In other words, if you enter the number key '1' five times in a row from one time, the sequence will be converted to 'ka'-> key-> ku-> ku-> ke (け)-> ko '. do. At this time, when the numeric key '1' is input six times or more, the numeric character '1' is converted to the corresponding character when the numeric key '1' is input once.

Thus, it is repeatedly converted according to the number of consecutive inputs of the numeric key '1'.

In addition, the characters assigned to the numeric keys '2' to '0' other than the numeric key '1' and the special keys '*' and '#' are also input by the method of inputting the predetermined number consecutively as described above.

However, the keypad of a conventional portable terminal and the Japanese input method using the same have a contiguous structure of a key arrangement in which consonants and vowels are not separated, and there is an inconvenience of having to continuously input keys because several letters are assigned to one numeric key. In addition, there is a problem in that it is not easy to correctly input a character that the user wants to input because it occurs when one key must be continuously input. Also, because each numeric key is arranged in a sequence so that the characters can be converted in order from 'A-> E-> Right-> E-> O' to each consonant, the character that needs to be input most frequently in the key input is wrong. In case of input, the character input time is delayed because the character to be inputted is input again.

Accordingly, the present invention has been made to solve the above problems, to provide a keypad of a portable terminal and a Japanese input method using the same to reduce the number of key input when Japanese input using the keypad of the portable terminal. There is this.

The present invention for achieving the above object, in the keypad of the portable terminal is assigned Japanese characters to each numeric key to input Japanese,

Key arrays are divided into keys consisting of vowels representing the columns and keys assigned to consonants representing the rows.

In addition, the present invention for achieving the above object, in the Japanese input method through a portable terminal having a keypad is divided into Japanese consonants and vowels,

The consonants representing the rows and the vowels representing the steps are selected, and the consonants and the vowels intersect with each other.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It should be noted that in the following description, only parts necessary for understanding the operation and operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to distract from the gist of the present invention.

In the following description, specific details of the keypad of the portable terminal and Japanese input method using the same are shown to provide a more general understanding of the present invention. It will be apparent to one of ordinary skill in the art that the present invention may be readily practiced without these specific details and also by their modifications.

2 is an exemplary view for explaining a keypad of a portable terminal according to an embodiment of the present invention.

Referring to FIG. 2, first, as a structure of a keypad 20 that separates a Japanese consonant and a vowel, the number keys '1' to '0' are '3', '6', and '9'. The vowel is assigned.

In other words, 'a' and '(') are assigned to the number key '3', and 'o' and '(U)' are assigned to the number key '6'. 'I' is assigned to the numeric key '9'.

In addition, the number keys ('1', '2', '4', '5', '7', '8', '0') except for the numeric keys '3', '6', and '9' Consonants are assigned to each. In addition, a specific key for selecting and inputting any one of a key operation to which a plurality of consonants are assigned among the corresponding numeric keys to which the consonants are assigned is provided. In the present invention, the specific key is referred to as '*' key.

The specific key '*' will be described in detail as follows.

For example, if you want to input '와', enter the number key '1' to which '와' is assigned once. Then, 'ka' of the first letter assigned to the numeric key '1' is first inputted and displayed on the display window of the portable terminal. When a specific key (*) is input within a predetermined time, 'WA' of the second letter allocated together with the first letter of the numeric key '1' is inputted and displayed on the display window of the portable terminal. In the present invention, in addition to the numeric key '1' as an example, if a specific key ('*') is input after inputting 'Me' assigned to the numeric key '2', 'TA' is inputted. If you input a specific key (*) after inputting '마' assigned to the numeric key '5', the key is arranged to input '하'.

In addition, the keypad 20 is provided with a sound tone / half tone selection key '#'.

The sound tone / half tone selection key '#' converts a specific character into a sound tone by one key input, and converts a specific character into a half-tone sound when two key inputs are successively performed. Here, the specific character means a character having a sound of sound and a sound of sound. In addition, the tone / half tone selection key '#' enters the numeric key '6' to select 'o' and then converts it to 'o'.

In addition, the keypad 20 is provided with a long / hap / yoyo selection key ('8'), the numeric key '0' is assigned a note / 'eun (ん)' to facilitate the pronunciation.

The long / tap / yono selection key '8' enables input of long, tactile, and note sounds into a character consisting of consonants and vowels.

In the method of inputting Japanese through the key arrangement structure of the keypad 20 described above, a consonant representing a row and a vowel representing a stage are selected to select one character of 50 degrees corresponding to the consonant and the vowel crossing. Will be entered.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described in detail above, the present invention can separately input consonants and vowels corresponding to Japanese, and by inputting the same character of any Japanese, a similar number of key inputs can be used, thereby repeatedly inputting the same keypad. This reduces the number of cases, so that the problem of incorrectly typing the corresponding character does not occur.

In addition, by having a keypad structure that separates the Japanese consonants and vowels, it is possible to predict the movement of the corresponding vowels to be input after inputting the Japanese consonants, thereby increasing convenience of character input.
