The code storage unit 120 includes a vowel code 122 and a vowel synthesis code 124.

The vowel code 120 stores a table for matching the vowel by the input key and the short and short signals. The short signal input of the first key among the four input keys is "ㅣ", and the long signal input of the first key is "ㅏ". ", The short signal input of the second key is" ㅡ ", the long signal input of the second key is" TT ", the short signal input of the third key is" ㅣ ", and the long signal input of the third key is" ㅓ ". And the short signal input of the fourth key to "-" and the long signal input of the fourth key to " ㅗ ".

The vowel synthesis code 124 stores a table for matching the vowels inputted with the vowels inputted immediately before the input vowels and the vowels combined to combine the vowels determined from the vowel codes. 결합, ㅏ and ㅣ combine ㅐ, ㅏ and ㅏ and ㅣ combine ㅒ, TT and TT combine ㅠ, TT and ㅣ combine ㅜ, TT and 결합 combine ㅝ, TT and ㅓ When 하면 and 결합 combine, ㅞ, ㅓ and 결합 combine ㅕ, ㅓ and ㅣ combine ㅔ, ㅓ and ㅓ and ㅣ combine ㅖ, ㅗ and 결합 combine ㅛ, ㅗ and ㅣ combine ㅚ, ㅗ If and 결합 combine, ㅘ, ㅗ and ㅏ and ㅣ combine and match with ㅙ.

The matching method is not limited to the above description and may combine the above method and a combination method by the existing Cheonjiin (-, ㅣ,.). For example, in the vowel code, the short signal input of the first first key after the consonant among the input keys is "|", the long signal input of the first key after the consonant is "ㅏ", and the first second after the consonant. The short signal input of the key is "ㅡ", the long signal input of the first second key after the consonant is "TT", the short signal input of the first third key after the consonant is "ㅣ", and the first third after the consonant The long signal input of the key is "ㅓ", the short signal input of the fourth key is "-", the long signal input of the fourth key is "ㅗ", and the vowel key input after the vowel is matched with. In the vowel synthesis code, among the vowels determined by the predetermined vowel code, ㅏ and 결합 combine, 결합, ㅏ and ㅣ combine, ㅐ, ㅏ and ㅏ and ㅣ combine, and ㅠ, TT and ㅣ combine ㅟ, TT and ㅓ combine ㅝ, TT and ㅓ and ㅣ combine ㅞ, ㅓ and 결합 combine ㅕ, ㅓ and ㅣ combine ㅔ, ㅓ and ㅓ and ㅣ If you combine ㅖ, ㅗ and ㅗ combine ㅛ, ㅗ and ㅣ combine ㅚ, ㅗ and 결합 combine ㅘ, ㅗ, ㅏ and ㅣ combine with ㅙ and combine ㅣ, ㅡ and ㆍ in a natural way You can do it.

In addition, when the short signal inputs of 1, 2, 3, and 4 keys are referred to as B, C, D, and A, and the long signal inputs are referred to as B ', C', D ', and A', the extended key combination as shown in FIG. It is also possible.

The temporary storage device 114 temporarily stores several characters entered before the entered characters and calls them as necessary to be synthesized with the newly entered characters. The program memory 116 stores a program for generating a character to be output according to a set rule. The CPU 112 calls the necessary data in the temporary storage unit and the program memory according to the input from the input unit, and generates a collection to control and output the data.

The output unit 130 includes an LCD driver 132 and an LCD display unit 134.

The LCD driver receives the character information to be output from the control unit 110 and drives the LCD to display it on the LCD, which is output through the LCD display unit and recognized by the user as a character.

4 is a flowchart illustrating a Hangul input / output method according to an embodiment of the present invention.

First, it detects which of the four input keys the manipulated vowel input key. In addition, it is determined whether the time for pressing the input key exceeds the set time to determine whether the signal is a long signal or a short signal. (S102) The vowel corresponding thereto is determined by judging the manipulated input key and the short and short signals, wherein a predetermined vowel code is used. (S110) Since the predetermined vowel code is mentioned in the description of FIG. 1, repeated description is omitted.

The character entered before the input vowel is called from the temporary storage device. In operation S120, it is determined whether the called character is a consonant or a vowel, and when the called character is a consonant, a character combined with the input vowel is generated. (S122, S124) When the called character is a vowel, a compound vowel is generated using a predetermined vowel synthesis code. (S126) Since the predetermined vowel synthesis code is mentioned in the description of FIG. 1, repeated description is omitted. Characters generated by the above process is stored in the temporary storage device for synthesis with the next character to be input and output through the output unit. (S128, 130)

FIG. 5 illustrates an embodiment of generating a composite vowel by the Korean input / output method according to the present invention, and illustrates a process of implementing a letter “example”.

First, when consonant "ㅇ" is input, it is stored in the temporary storage device and output through the output unit. If it is detected that the third key is input as the long signal among the four input keys (S200, S202), the corresponding vowel "ㅓ" is matched and "o" previously called from the temporary storage device is called. (S210, S212, S214) "o" is synthesized by combining the called "o" and "o", and stored and output. (S216)

If it is detected that the third key is input as the long signal among the four input keys, the corresponding vowel “ㅓ” is matched and the previously input “er” is called from the temporary storage device. (S220, S222, S224) For "ㅕ" and "ㅓ", match "에" from the vowel synthesis code, generate "F", store it, and output it. (S226, S228)

When it is detected that the first key or the third key is input as a short signal among the four input keys, the corresponding vowel "|" is matched and "F" previously input from the temporary storage device is called. (S230, S232, S234) "ㅓ" and "ㅓ" are combined with "ㅣ" to match "ㅖ", generate "Yes", store it, and output it. (S236, S238) Through the above-described method, "Yes" requiring five input key manipulations may be implemented through only four key manipulations.

On the other hand, the present invention includes the following input and output devices and methods.

In the method of consonant input, consonants are a total of 19 consonants a, b, c, d, k, k, k, k, k, k, k, k, k, k, k, k, k. Consists of. Here, nine frequently used vowels of a, b, c, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, 배치 are placed in the first half so that they can be entered once. The five consonants of ㄲ, ㄸ, ㄸ, ㅆ, ㅉ Enter after pressing shift key 0. The other five consonants of ㅌ, ㅌ, ㅋ, ,, ㅎ can also be entered after pressing the shift key, and they will be replaced by empty spaces.

Here, the shift key means that after pressing the shift key once, the input method of Figure 2 can be taken. After pressing the key of figure 2, it is automatically reduced to figure 1. That is, when the shift key is pressed once, the input operation of the shift key is terminated by one action.

For example, if you want to enter 'ㄲ', press the shift key, then press the 'a' key to express 'ㄲ', and when you enter 'ㅎ', press the shift key twice in succession. And, * and # represent left and right direction keys, respectively, so it is used for typo or typographical input or one space. Figure 3 shows the overall configuration.

The following consonant input method is a proposal for the case where there is no four-way keypad or for some reason it is necessary to operate with 12 numeric keypads.

<Figure 4>

First, as shown in Figure 4, the symbol corresponding to 'ㅗ' is assigned to key 8, and the symbol corresponding to 'ㅏ' is assigned to '*' key for '*', and 'ㅜ' for # key, respectively. Then assign different consonants to the remaining keypads 1,2,3,4,5,6,7. The 9 key can be used as a shift key, a space key, or a Korean, English, or numeric switch key. The following example shows how to use the space key or the hin, alpha, and digit switch keys. Each consonant can be input with one to three inputs. Specific applications are as follows.

Press 1 key once, 'ㄱ', press twice, '두', press three times, 'ㅋ' is entered.

For example, to enter the text Hong Gil-dong, type the following:

Ex) Hong Gil-dong 7,7-8'-7-1-#-2,2-3-8'-7

Monday 7-0 '*'-2,2-7-8 ', 8-7-#-2,2

Lim Gakjeong 7-#-4,4,4-1'1-* '-1-5-*'-7
