Description

Hangul input device and method for inputting Hangul using the same}

The present invention relates to a Hangul input device used in a communication or electronic device, and more particularly, to a Hangul input device provided with a keypad for easily inputting Hangul with a small number of inputs and a Hangul input method using the same.

Due to the development of the electronic communication industry, as electronic communication devices are gradually miniaturized and changed into portable devices, there is a demand for a reduced letter input device having a small number of keys designed. On the other hand, in a character input device such as a terminal and a telephone of a portable telephone, a keypad having 12 keys and about 4-5 function keys designed for character input is used.

Through the character input device, all numbers, English letters, symbols, and Korean characters are input. A key for assigning 26 alphabetic characters for English input is required, and a key for assigning 19 consonants and 21 vowels for Korean input. Is required. Therefore, various techniques have been studied to efficiently assign letters, vowels, and vowels of numbers, English alphabets, and Korean letters to each key of a keypad of a reduced-size character input device.

In particular, Korean citizens are much more likely to input Hangul than Korean, so it is urgent to develop a compact character input device provided with a keypad designed to easily input Hangul.

An example of a reduced character input device is disclosed in Korean Patent Registration No. 159191 (hereinafter referred to as “priority patent”), and a keypad of the input device according to the prior patent is shown in FIG. 1.

Referring to FIG. 1, in a keypad 10 having an asterisk (*), a pound sign (자), and twelve keys in which Arabic numerals from 0 to 9 are arranged, the numeric key 1 has a consonant "a" and Assign "ㅋ", assign the consonants "ㄷ" and "ㅌ" to the numeric keys 2, assign the consonants "ㅂ" and "t" to the numeric keys 3, and assign the consonants "ㅅ" and "ㅎ" to the numeric keys 4. ", Assigns the consonants" ㅈ "and" ㅊ "to the numeric keys 5, assigns the consonants" ㅇ "and" ㅁ "to the numeric keys 6, and assigns the consonants" b "and" ㄹ "to the numeric keys 7 Assigned. A numeric key 8 is assigned a first vowel input key "→", a numeric key 9 is assigned a second vowel input key "·", and a numeric key 0 is assigned a vowel input key "↓".

Therefore, to input the consonants "ㄱ", "ㄷ", "ㅂ", "ㅅ", "ㅈ", "ㅇ" and "ㄴ", respectively, the numeric keys 1, the numeric keys 2, the numeric keys 3, and the numeric keys 4 , Numeric keys 5, numeric keys 6 and numeric keys 7 once, to enter consonants "ㅋ", "ㅌ", "ㅍ", "ㅎ", "ㅊ", "ㅁ" and "ㄹ" respectively Press Numeric Key 1, Numeric Key 2, Numeric Key 3, Numeric Key 4, Numeric Key 5, Numeric Key 6, and Numeric Key 7 twice in succession. Then, to enter the double consonants "ㄲ", "ㄸ", "ㅃ", "ㅆ" and "ㅉ", press "*" followed by the numeric keys 1, 2, 3 4, or 5. have.

According to the prior patent, a numeric key is used to input a consonant, a numeric key is continuously used for a predetermined consonant, and in some cases, "*" is used together with the numeric key.

In other words, in the above-described method, each of the rhyme "ㄲ" and the vowel "ㅋ" related to the basic consonant "" a "uses the numeric keys, respectively, or uses the numeric keys consecutively or merges the numeric keys and the other keys. It is determined by whether or not to use it, and their input system is binary. In the same way, the input process of "ㄸ" and "ㅌ", "ㅃ" and "ㅍ", "ㅉ" and "ㅊ" is binary, which makes the input process somewhat complicated. In addition, when different consonants overlap to form a finality, that is, "ㄳ", "ㄶ", "ㄵ", "ㄺ", "ㄻ", "ㄼ", "ㄽ", "ㄾ", "ㄿ", When entering "ㅀ" and "ㅄ", the key must be pressed 2-4 times. In particular, "ㄶ", "ㄺ", "ㄼ", and "ㄽ" must be entered three times in total. For "ㄻ", "ㄾ", "ㄿ" and "ㅀ", there are 4 keystrokes. need. That is, when the method of the prior patent is used, the number of key inputs decreases significantly compared to other conventional Korean input methods, but the number of key inputs during consonant input (especially finality) is not greatly reduced.

In addition, in the vowel input using the prior patent, any vowel can be input using "→", "·" and "↓". Specifically, the input of "·" is required for the vowels except "-", "|", and "ㅢ". However, "·" is changed depending on whether "ㅡ" or "ㅣ" comes before or after it, and thus, when a user inputs a double vowel such as "ㅘ", "ㅙ", "ㅝ", "ㅞ", etc. There is a disadvantage that it is difficult to easily grasp the writing order.

Accordingly, the applicant of the present application has sought a method for reducing the number of inputs during Hangul input, especially a consonant input, to quickly and easily input Hangul.

In addition, to solve the problem of the above-described vowel input of the prior patent has been asked for a method that can easily and quickly proceed to Hangul input.

Accordingly, an object of the present invention is to provide a Korean input device provided with a keypad for inputting consonants of Korean characters with as few input times as possible and a Korean input method using the same.

Another object of the present invention is to provide a Korean input device provided with a keypad capable of easily and quickly inputting a vowel, in particular a double vowel, and a Korean input method using the same.

3 is a diagram illustrating an example of an arrangement state of a keypad of a Hangul input device according to the present invention.

4 is a view showing another example of the arrangement of the keypad of the Hangul input device according to the present invention.

5 is a flowchart illustrating an example of a Hangul input process according to the present invention.

In order to achieve the object of the present invention, the Hangul input device, a key pad, a code vector generator for generating a code vector corresponding to the pressed key when the key designed is pressed, and stores the code vector output from the code vector generator And a phoneme code generator for receiving a code vector from the controller and outputting a phoneme code corresponding to the code vector, and a phoneme code from the phoneme code generator. It contains an autometa that accepts and combines Hangul.

In more detail, a vowel input key, a plurality of consonant input keys in which one or more consonants including at least one terminal sound for deriving a hard sound and a pulsation among consonants constituting the Korean consonant are assigned to the keypad and 1: 1 A conversion key used subsequent to a predetermined consonant input key of the plurality of consonant input keys assigned to and used to generate a consonant and a sound of a consonant set in a predetermined consonant input key of the plurality of consonant input keys assigned to 1: 1; Placed.

Here, the consonant input keys include keys in which at least "a", "c", "ㅂ", "ㅅ", "o", and "j" are assigned at 1: 1, preferably, "a", “B”, “c”, “ㄹ”, “ㅁ”, “ㅂ”, “ㅅ”, “ㅇ” and “ㅈ” include keys assigned 1: 1.

As a vowel input key, three keys arranged with "ㅡ", "ㅣ" and "·" can be used. As another example, two vowel input keys assigned with only "ㅡ" and "ㅣ" can be used. have. In the latter case, a conversion key is used to distinguish two or more vowels formed by a combination of two vowel input keys in the writing order.

The conversion key used for vowel input can be used as the same key as the conversion key used for consonant input, or each conversion key can be assigned to a different key. However, when the converging keys arranged at the same position are used for consonant and vowel input, the key arrangement of the keypad becomes more efficient.

In addition, in the keypad of the Hangul input device according to the present invention, a key for notifying the change from the Hangul input mode to the special character input mode and a key for notifying the return to the Hangul input mode are designed. Special characters are assigned to input or conversion keys.

When inputting Hangul using the Hangul input device, if the control unit determines that the code vector stored in the memory unit and the newly input code vector are related, the control unit newly inputs the code vector stored in the memory unit. The code vectors are sequentially stored, and at the same time, the control unit sends the code vectors sequentially stored in the memory unit to the phoneme code generator, and the control unit determines that the code vector already stored in the memory unit is not related to the newly input code vector. When it is determined, the memory unit is reset, and only the newly input code vector is stored in the memory unit, and the newly input code vector is sent to the phoneme code vector generator.

If the generated code vector is a code vector corresponding to a key for notifying the change to the special character input mode, the control unit resets the memory unit and stores a code vector indicating the change to the special character input mode in the memory unit, and the operation mode. Change from Korean input mode to special character input mode.

Hereinafter, the Hangul input device according to the present invention will be described in detail with reference to FIGS. 2 to 5.

The principle of the present invention will be described below in detail.

For input of consonants, among the 19 consonants that constitute Korean's initial consonants, the terminal sound that derives the rhythm and the horn is assigned 1: 1 to the keys of the keypad, and the vowel and the rhyme use the key and the conversion key corresponding to their basic consonants. It was shown. In other words, if you press the key corresponding to the terminal sound, which is the mother of rhythm and horn, and press the convert key once, the sound of the basic consonant is displayed.If you press the key corresponding to the basic consonant and press the Transform key twice in succession, the sound of the basic consonant is To appear.

To input Korean vowels, the basic elements of vowels “ㅡ” and “ㅣ” were used, and the above-described conversion key was used to solve the problem of duplication of vowels caused by their writing order. For example, there are three vowels that can be formed by the writing order of "-" and "-": "ㅓ", "TT" and "ㅢ". One of these three will appear only when the basic elements of the vowel are sequentially entered without using the transform key, and the other one will appear when the primary element set input key and the transform key are entered one time sequentially. And, the other one appears when two basic element set input keys and conversion key are used consecutively. The same method was used for a plurality of other vowels formed by the same writing order of vowel basic elements.

2 is a block diagram schematically illustrating an example of a Hangul input device for implementing the spirit of the present invention, and FIGS. 3 and 4 show examples of arrangement states of a keypad of the Hangul input device of FIG. 2. In particular, FIG. 3 illustrates a key pad showing a state in which a conversion key is used only when the consonant is input, and FIG. 4 illustrates a keypad in which the conversion key is used not only in consonant input but also in vowel input. 5 is a flowchart illustrating an example of a Hangul input process according to the present invention.

The Hangul input device of FIG. 2 includes a key pad 21 to which a plurality of consonant input keys, a vowel input key, and a conversion key are assigned, and the keypad 21 so that a machine or a device can recognize a character recognized by the input user. A code vector generator 22 for generating a code vector corresponding to an input key, a phoneme code generator 26 for outputting a phoneme code corresponding to the code vector, a standard code table storing a standard code vector and a phoneme code corresponding thereto The unit 27 and the phoneme code generator 26 include an autometer 28 for generating characters by combining the phoneme codes output from the phoneme code generator 26. In addition, the Hangul input device according to the present invention, the memory unit 25 receives the output of the code vector generator 22 and stores a predetermined code vector, and stores the code vector in the memory unit 25 under a predetermined condition and the memory It further includes a control unit 24 programmed to reset the unit 25. When a new code vector is generated, the controller 24 checks whether there is a code vector in the code vector and the memory unit 25, and when these code vectors are different types, the previously stored code vector is stored in the memory. After removing from the negative and storing only the newly input code vector, the newly stored code vector is transferred to the phoneme code vector generator 26. However, when the conversion code vector is input, the newly input conversion code vector is sequentially stored in the memory unit 25 without resetting the memory unit 25.

For example, if the newly generated code vector is a vowel code vector, and the code vector already stored in the memory section 25 is a consonant code vector or another type of code vector, the memory section 25 is reset. The memory unit 25 stores only the newly input consonant code vector. At the same time, the control unit 24 sends the consonant code vector to the phoneme code generator 26 so that the corresponding phoneme code is output.

Referring now to FIG. 3, an example of a key arrangement state of the keypad 21 of the Hangul input device of FIG. 2 will be described in detail.

The keypad of FIG. 3 is one of the keypads used in the portable telephone. The keypad of the present invention is not limited to the above-described type, and in addition to the portable telephone, a reduced Hangul input device such as a general telephone, a calculator, and an electronic notebook.

And from the center to the bottom of the keypad 21, twelve numeric keys and special character keys of three horizontal lines and four vertical lines are provided.

From the left to the right of the first line, the numeric keys 1, 2, and 3 are located, and from the left to the right of the second line, the numeric keys 4, the numeric keys 5, and the numeric keys 6 are located. From left to right, number keys 7, number keys 8, and number keys 9 are located. From left to right of the last line, keys *, number keys 0 and key ＃ are located.

One of the basic elements for vowel input, "ㅣ" is assigned to the numeric key 1, the other basic element "-" is assigned to the numeric key 2, and another vowel input element "·" is assigned to the numeric key 3. It was. This vowel input system is the same as the vowel input system in the foregoing patent.

And the consonants "ㄱ", "ㄴ", "ㄷ", "ㄹ", "ㅁ", "ㅂ", "ㅅ", "ㅇ" and "ㅈ", respectively. , Number key 7, number key 8, number key 9, key *, number key 0 and key ＃ respectively. The above-mentioned vowels and consonants are used as basic vowels and basic consonants in the present invention. Among the consonants in Korean that can be used as primary and final consonants, consonants that are not included in the basic consonants are pulsation, horn, and double consonants. On the basis of these basic vowels and basic consonants, a conversion key used to express all the consonants of the Hangul described above Is assigned to the access key. The access key is used for Internet access when the portable telephone is not under any kind of input mode, but is designed to be used as a conversion key in the Hangul input mode.

In addition, as an example for inputting a special character, "?" For the numeric keys 4, "." For the numeric keys 5, "!" For the numeric keys 6, ";" for the numeric keys 7, and ";" for the numeric keys 8 Is assigned "＾" to "#" for the numeric key 9, "*" for the key *, "-" for the numeric key 0 and "♥" for the key ＃. In the English alphabet, a plurality of letters are assigned to each number key, for example, three or four, respectively, and the number of special characters that can be input in the English operation mode are keys *, number keys 9 and keys. Assigned to #.

When inputting special characters, it is required to change from Korean mode input state to special character input state. To do this, press "Menu key" and then press the number key or key * or key # corresponding to the special character and finally " Press "OK". Pressing the "OK" key is programmed to return to the original operating mode, the Korean input mode.

In the keypad of FIG. 3, the connection key is used as the conversion key, but the present invention is not limited thereto. As long as the microprocessor unit that controls the overall operation of the cellular phone controls the selected conversion key to perform an operation that is distinct from their unique function, in the Hangul input mode, any of the keys placed on top of the keypad can be used. have. You can also design a new key and use it as a translation key. The arrangement of the consonant input key, the vowel input key, the conversion key, and the special character input key on the keypad 21 is not limited to that shown in FIG. 3 and may be variously changed and used.

In addition, the arrangement state of the English alphabet may also be variously changed. Since the present disclosure relates to the input system of the Korean alphabet, a description of the English input process will be omitted below.

In the Hangul input device having the above-described keypad 21, when a predetermined key of the keypad 21 is input, the input information is transmitted to the code vector generator 22 to generate a code vector corresponding to the pressed key. The input key and the corresponding code vector are shown in Table 1.

In Table 2, code vectors A4 to A9, and A *, A-, and A # and corresponding phoneme codes A1 to A9 represent code vectors and phoneme codes in a special character input mode.

In the Hangul input mode, when the numeric key 4 of the keypad shown in FIG. 3 is pressed to input the consonant "a", the code vector "4" is output from the code vector generator 22 as shown in Table 1, The code vector is stored in the memory 25 by the control unit 24 and transferred to the phoneme code generator 26 to generate a phoneme code "1" corresponding to the code vector "4". This value is then sent to the autometer 28. Similarly, in order to input the "b" consonant, when the numeric key 5 of the keypad is pressed, the code vector generator 22 outputs the code vector "5" and is stored in the memory unit 25, and the code vector "5". The phoneme code outputs the phoneme code "4" corresponding to the code vector "5" from the phoneme code generator 26 via the control part 24. FIG. This value is then passed to the autometer 28 to complete the input of the consonant "b". In the same way, you can enter the consonants "ㄷ", "ㄹ", "ㅁ", "ㅂ", "ㅅ", "ㅇ" and "ㅈ".

Among the consonants (including the initial and final) that are not arranged on the keypad, the “음”, “ㅌ”, “”, “” and “” corresponding to the pulsation, “ㄱ”, “ㄷ”, “ 숫자 "," ㅈ "," ㅇ "and press the number key, and then convert key in succession Press once.

For example, to enter "ㅌ", press numeric key 6 followed by the change key. When is pressed once, the code vector generator 22 outputs the code vector "6" and immediately outputs the code vector "C". The basic vector 6C is stored in the memory unit 25 and transferred to the phoneme code generator 26 by the operation of the controller 24. The phoneme code generator 26 is shown in Table 2 as will be described later. The phoneme code "28" corresponding to the code vector "6C" is generated and transmitted to the auto meta 28.

And, among the consonants (including primary and final) that are not arranged in the keypad, "ㄲ", "ㄸ", "ㅃ", "및" and "에" corresponding to hard sound are "a" and "c". , "ㅂ", "ㅅ" and "ㅈ", then press the number key, Press twice.

For example, to enter "ㄸ", press numeric key 6 followed by the change key. When is pressed twice, the code vector generator 22 outputs the code vector "6" and immediately outputs the code vector "CC". The three basic vectors 6CC are stored in the memory unit 25 and transferred to the phoneme code generator 26 by the operation of the controller 24. The phoneme code generator 26 is described in Table 2 below. As shown in FIG. 6, a phoneme code “8” corresponding to the code vector “6CC” is generated and transmitted to the auto meta 28. In other words, the input of the horn and the horn is made to press the numeric key indicating the dominant sound of the horn and the horn once, and the rest is divided according to the number of times of use of the conversion key, so that the horn and the horn are easily input. .

In the case where three different consonants can be made by using the consonant basic input key and the conversion key together, the control unit 24 presses only the basic consonant input key without using the conversion key or inputs the basic consonant input. In the case where the conversion key is pressed three times in succession after the key (in the multiple of 3), the same vector code is transmitted to the phoneme code generator 26. In the same way, the same vector code is used for the phoneme code even when the basic consonant input key and the conversion key are used once through the control unit 24 and the basic consonant input key and the conversion key are pressed four times (the number of times the remainder divided by three) is one. The same vector code is generated even when the basic consonant input key and the conversion key are used twice, and when the basic consonant input key and the conversion key are pressed five times (the number of times the remainder divided by three) is pressed. (26). For the consonants "ㅇ" and "ㅎ", which are produced by two different consonants by the conversion key, if the number of times the conversion key is divided by 2 is 0, the basic consonant "ㅇ" is 1, and the rest is 1 In the case of the vowel "ㅎ" to appear.

In the present embodiment, the conversion key is pressed once when the sound is input and the conversion key is pressed twice when the hard sound is input. However, the present invention is not limited thereto. According to the arrangement of keys other than the numeric keys, the present invention may be variously modified and used for the convenience of the user.

Based on the above-described consonant input method, a consonant consonant composed of different consonants "ㄳ", ",", "ㄺ", "ㄻ", "ㄼ", ",", "ㄾ", "ㄶ", "ㄾ" , "ㄿ" and "ㅀ" can also be entered using the numeric keys or the numeric and conversion keys corresponding to each consonant, for example, the numeric keys 7 and the numeric keys 4 to enter "ㄺ". Press consecutively to output "74" as the code vector, which is converted to the phoneme code "10". To enter "ㄿ", press the number key 7, the number key 9 and the conversion key. When is pressed successively, the code vector "79C" is transmitted to the phoneme code generator 26 via the control part 24, which is converted into the phoneme code "15" and transmitted to the autometa 28.

If you use the preceding patent when entering "ㄻ", "ㄾ", "ㄿ" or "ㅀ", press the numeric key 7 twice and press another numeric key (numeric keys 6, numeric keys 2, numeric keys 3 or numeric keys 4). ) Had to be pressed twice, according to the present invention, "ㄻ" is to press the numeric key 7 and the numeric key 8 (total 2 times), "ㄾ" is the numeric key 7, numeric key 6 and the conversion key (3 times in total) ), Press 은, digit key 7, digit key 9 and conversion key (3 times total). Press 키, 7, digit 0 and conversion key (3 times) It is pressed. That is, the prior patent can reduce the number of inputs to three circuits that had to be input four times.

On the other hand, the frequently used symbols, such as question marks, periods, exclamation marks, semi-colons, etc. are used when a menu key and a consonant input key are continuously pressed. For example, to enter a question mark, press the Menu key once in Korean mode. Then, as shown in Table 1, the code generator 22 outputs the code vector "A", and the control unit 24 that detects this detects that the operation mode is changed from the Korean input mode to the special character input mode. Next, when the key to which a special character is assigned and the numeric key 4 to which a question mark is assigned are pressed once, the code vector "A *" is stored in the memory unit 25, and this value is transferred to the phoneme code vector generator 26. FIG. Transmitted to output the phoneme code "A7" in the corresponding special character input mode and transmits it to the auto meta (28). On the other hand, when the control unit 24 detects that generation of the code vector "B" (confirmation key) indicating the return to the original operation mode after the code vector "A" of the menu key which is the special character input mode start key, the operation state of the telephone, Will return to Hangul input mode from the special character input state and wait for the next code vector.

In addition, since the vowel input system is the same as the input system of the prior patent, a detailed description thereof will be omitted below.

In summary, one of the nineteen consonants that make up Korean's initial consonants, the terminal sound deriving the sound and the sound, is placed on each key of the keypad on a 1: 1 basis, and the terminal sound is converted into the sound of the sound between the sound and sound of the other key on the keypad. When arranged with a conversion key, the number of inputs of consonants is reduced when inputting not only 19 consonants but also double consonants.

4 shows a state in which a conversion key is assigned to any one of the numeric keys. The consonant input system is the same as using the above-described keypad of FIG. In the keypad of FIG. 3, three basic elements are used for vowel input. In FIG. 4, only two basic elements are used, and a conversion key related to consonant input is used for vowel input.

On the other hand, the arrangement of the consonant input key, the vowel input key and the conversion key, and the arrangement of the special character input key in the keypad 21 'is not limited to that shown in FIG.

In detail, one of the basic elements for the vowel input, "ㅣ" is assigned to the numeric key 1, and the other basic element, "ㅡ", is assigned to the numeric key 2. And the consonants "ㄱ", "ㄴ", "ㄷ", "ㄹ", "ㅁ", "ㅂ", "ㅅ", "ㅇ" and "ㅈ", respectively. , Number key 7, number key 8, number key 9, key *, number key 0 and key ＃ respectively. The above-mentioned vowels and consonants are used as basic vowels and basic consonants in the present invention. On the basis of these basic vowels and basic consonants, a conversion key used to express all the consonants and vowels of Hangul. Is assigned to numeric key 3.

Other key assignments for inputting special characters and key assignments for English input, and arrangements of the confirm key, the end key, the menu key, the call key, the arrow direction key, and the access key on the upper part of the keypad are similar to those of FIG. same. However, the access key no longer functions as a conversion key in the keypad of FIG. 4, but only as an internet access key, which is its original function.

Like the keypad 21 shown in FIG. 3, when a predetermined key of the keypad 21 ′ of FIG. 4 is input, the input information is transmitted to the code vector generator 22 to generate a code vector corresponding to the pressed key. do. The input key and the corresponding basic code vector are shown in Table 3.

Meanwhile, in Table 4, code vectors A4 to A9, and A *, A-, and A # and corresponding phoneme codes A1 to A9 represent code vectors and phoneme codes in a special character input mode.

The consonant input method and the special character input method are the same as those described with reference to FIG. 3. However, when the conversion key is pressed, the numeric key 3 is pressed without pressing the access key, and correspondingly, the code vector is changed from "C" to "3". Hereinafter, only a vowel input method having an input system different from that of the keypad of FIG. 3 will be described.

Press numeric key 1 to enter the vowel “ㅣ”; press numeric key 2 to press the vowel “ㅡ”. For example, when the numeric key 1 is pressed, a code vector "1" is generated, which causes the phoneme code "51" to be generated, and the auto meta 28 uses the vowel "|" for the Hangul combination.

Now let's take a look at the input methods of the other vowels except "ㅡ" and "ㅣ".

First, there are two vowels that can be formed by the writing order of "|" and "-". Therefore, an identifier for distinguishing these two vowels is required, and the present invention requires a conversion key for this purpose. Was used. In the present embodiment, when the vowel “ㅗ” is input, the numeric key 1 corresponding to “ㅣ” and the numeric key 2 corresponding to “ㅡ” are sequentially pressed and subsequently converted keys. To be pressed. Therefore, when the numeric key 1 and the numeric key 2 are pressed, the code vectors "1" and "2" are sequentially output and stored in the memory unit 25. Accordingly, as shown in Table 2, the code vector "12" and the corresponding phoneme code "31" are output. On the other hand, when the numeric key 1, the numeric key 2, and the conversion key are pressed in sequence, the code vectors "1", "2" and "3" are output sequentially, which is shown in Table 4, and the code vector "123". And the corresponding phoneme code "39". That is, even though vowel input keys (or basic vowels) having the same order and configuration are used, each standard code vector and a phoneme code are distinguished according to the use of the conversion key and the number of use of the conversion key.

In addition, since there are three vowels which can be formed by the writing order of "-" and "-", "ㅓ", "TT", and "ㅢ" are three. To input "TT", input the numeric key 2 corresponding to "ㅡ" and the numeric key 1 corresponding to "ㅣ", and enter the conversion key once. To input "ㅢ", enter the numeric key 2 and After entering the numeric key 1, the conversion key was input twice.

The vowels that can be formed by the writing order of "ㅣ", "ㅡ", and "ㅣ" are "ㅐ" and "," and are based on "ㅐ". Numerical key 1 corresponding to "0", numeric key 2 corresponding to "ㅡ" and numeric key 1 corresponding to "ㅣ" were inputted, and then a conversion key was pressed.

The vowels that can be formed by the writing order of "-", "|", and "|" are ",", ",", "ㅠ", and in this embodiment, "ㅔ" is based on "". To input 입력, input the numeric key 2 corresponding to “ㅡ”, the numeric key 1 corresponding to “ㅣ” and the numeric key 1 corresponding to “ㅣ”, and then enter the conversion key once. To input ", enter numeric key 2, numeric key 1 and numeric key 1, and then enter the conversion key twice.

On the other hand, in the case where there are two or more vowels that can be created by the writing order, which vowel is used for which vowel is not determined as described above, it can be variously changed by the user's convenience.

And, the vowel "ㅑ" can be entered by pressing the numeric key 1, the numeric key 2 and the numeric key 2 sequentially, the vowel "ㅒ" sequentially press the numeric key 1, numeric key 2, numeric key 2 and numeric key 1 The vowel “,” can be entered by pressing the numeric key 2, the numeric key 2 and the numeric key 1 in sequence. The vowel “ㅖ” is the numeric key 2, the numeric key 2, the numeric key 1 and the numeric key. You can press 1 sequentially. In addition, the vowel "ㅘ" can be entered by pressing the numeric key 1, the numeric key 2, the numeric key 1 and the numeric key 2 in sequence, the vowel "ㅙ" is numeric key 1, numeric key 2, numeric key 1, numeric key 2, can be entered by pressing the numeric key 1, the vowel "ㅛ" can be entered by pressing the numeric key 1, numeric key 1, numeric key 2 in sequence. Then, the vowel “ㅝ” can be entered by pressing the numeric key 2, the numeric key 1, the numeric key 2 and the numeric key 1. The vowel “ㅞ” is the numeric key 2, the numeric key 1, the numeric key 2, the numeric key 1 and Press numeric key 1 to enter.

Referring to FIG. 5, the input process of consonants and vowels using the Hangul input device employing the keypad of FIG. 3 or 4 will be described in detail.

When a predetermined key of the keypad 21 is pressed, a code vector corresponding to the key input from the code vector generator 22 is generated (step S2). The code vector is input to the control unit 24. When the code vector is input, the control unit 24 checks the type of the code vector, accesses the memory unit 25, and determines whether the code vector is already stored and if so, what kind of code vector. Here, the type of code vector means a vowel code vector representing a vowel input key, a consonant input code vector representing a consonant input key, a conversion code vector representing a conversion key, and a code vector representing a change in an operation mode (corresponding to a menu key and an confirm key Code vector). The consonant code vector has a basic code vector of "4", "5", "6", "7", "8", "9", "0", "*", or "as shown in Table 1 or Table 3. # ", The vowel code vector is" 1 "," 2 "," 3 "according to Table 1 and" 1 "," 2 "according to Table 3, and the conversion code vector is" C "according to Table 1 And "3" according to Table 3. And the code vector indicating the change of the operation mode is "A" and "B" according to Table 1 and Table 3.

If no code vector is stored in the memory section 25, the code vector is stored in the memory section 25 (step S3) and simultaneously transferred to the phoneme code generator 26 through the control section 24. The phoneme code generator 26 searches the standard code table 27 and checks whether there is a code vector identical to the input code vector, and if so, outputs a phoneme code corresponding to the code vector (step S4). The output phoneme code is transmitted to the auto meta 28, combined (step S5), and then displayed on the display device 30 via the output device 29 (step S6).

If the code vector is already stored in the memory unit 25 and the control unit 24 detects that a code vector such as the type of the code vector stored in the memory unit 25 is generated (that is, the following description will be described below). The control unit 24 sequentially stores the newly generated code vector together with the code vector stored in the memory unit 25 (step S3). The code vector stored first is placed at the highest position, and the newly input code vector is placed at the next lower position.

At the same time, the control unit 24 sends the code vector stored in the memory unit 25 to the phoneme code generator 26, wherein the transmitted code vectors are formed according to the order of storing the individual code vectors stored in each step. This includes the sequence of code vectors from the most significant region to the least significant digits. The code vector includes a code vector formed by removing code vectors from the top region one by one until only the code vector of the lowest region remains. For example, when the consonant code vector "7" is stored and the consonant code vector "0" is stored later, the code vector "7" and "0" are sequentially stored in the memory unit 25, and the phoneme code generator The code vector sent to (26) becomes "70" and "0". Further, when vowel code vectors "1", "2", and "1" occur sequentially and are sequentially stored in the memory unit 25, the code vectors transferred to the phoneme code generator 26 are "121" and "21". "," 1 ". The order in which the plurality of code vectors are sent to the phoneme code generator 26 is "70", "0", or "121", "21", "1", and the code vector sent first is a standard code table section ( 27, the search for subsequent code vectors is omitted.

When the consonant code vectors "7" and "0" are sequentially generated and stored, the phoneme code "9" corresponding to the code vector "7" and the phoneme code "23" corresponding to the code vector "70" are autometers (28). Will be entered sequentially. Therefore, in the auto meta 28, the phoneme code and phoneme code " 9 " previously input are combined and displayed, and then the phoneme code and phoneme code " 23 "

On the other hand, if the code vector is already stored in the memory unit 25 and the control unit 24 detects that a code vector different from the type of the code vector stored in the memory unit 25 is generated (hereinafter, the association The control unit 24 resets the memory unit 25 and stores only the newly input code vector in the memory unit 25 (step S3). . However, when the newly generated code vector is the conversion code vector, the same code vector of the same type is handled without resetting the memory unit 25.

At the same time, the controller 24 transfers the newly stored code vector to the phoneme code vector generator 26. The phoneme code generator 26 checks whether there is the same code vector as the code vector input from the standard code table unit 27, and if so, outputs a phoneme code corresponding to the code vector (step S4). The output phoneme code is transmitted to the auto meta 28, combined (step S5), and then displayed on the display device 30 via the output device 29 (step S6).

For example, when the newly generated code vector is a vowel (consonant) code vector, and the code vector already input is a consonant (vowel) code vector, the memory unit 25 is reset and the memory unit 25 is reset. Only the newly input consonant (vowel) code vector is stored. The consonant (vector) code vector is then sent to the phoneme code generator 26 so that the corresponding phoneme code is output.

On the other hand, when the newly generated code vector is a code vector " A " indicating an operation mode change, it is different from the code vector stored in the memory section 25, so that the memory section 25 is reset and the code vector " A " Only is saved, the keypad is switched to the special character input mode. And according to Table 2 and Table 4, there is no phoneme code corresponding to this code vector "A", so that no character combination is achieved. During the special character input mode, when a key on which a special character is placed is pressed, for example, when a key * is pressed, a code vector "*" is generated, which is stored in the memory unit 25. At this time, the control unit 24 is programmed to store the code vector " * " without storing the code vector indicating the operation mode change without being deleted, so that the phoneme code " A1 " corresponding to the code vector " A * " Will be output. The phoneme code " A1 " is transmitted to the autometer 28 to be combined with Hangul to display the special character " * " Subsequently, when a special character is continuously input, the control unit 24 deletes the previous code vector (for example, "*") while leaving the code vector "A" intact and displays a code representing the newly entered special character. Only the vector is stored in the memory unit 25. When the code vector "B" is generated, the controller 24 detects the end of the special input mode and the return to the basic operation mode, that is, the Korean input mode, and controls the aforementioned Korean input operation.

In inputting Korean using a keypad having the configuration as shown in FIGS. 3 and 4, the method of calculating a phoneme code for the input vowel and / or consonant is not limited to the method described with reference to FIG. 5. The transform code vector works with a consonant code vector or vowel code vector generated before the code vector to generate a code vector that represents a new, modified consonant or vowel unlike a consonant code vector or vowel code vector. As long as the controller 24 is programmed, any type of Hangul input method can satisfy the spirit of the present invention.

Using the method described in FIG. 5 and using the keypad of FIG. 4, a process of inputting the sentence "An ugly tree protects a mountain" will be described in detail.

The order of key input of keypad is numeric key 8-numeric key 1-numeric key 2-conversion key-key *-key *-numeric key 1-numeric key 2-numeric key 1-numeric key 0-numeric key 4-numeric Key 1-Numeric Keys 5-Numeric Keys 5-Numeric Keys 1-Numeric Keys 2-Numeric Keys 8-Numeric Keys 2-Numeric Keys 1-Conversion Keys-Numeric Keys 4-Numeric Keys 1-Numeric Keys 2-Key *-Numeric Key 1-Numeric Key 2-Numeric Key 5-Numeric Key 0-Numeric Key 2-Numeric Key 7-Key #-Numeric Key 1-Numeric Key 4-Conversion Keys-Numeric Key 1-Numeric Key 5-Numeric Key 6 Numeric Key 1-Numeric Key 2-Numeric Key 5-Numeric Key 5

In the keypad 21, when the numeric key 8 is first pressed, the code vector generator 22 generates a code vector " 8 ", which is transmitted to the controller 24. The control unit 24 accesses the memory unit 25 to confirm that there is no stored code vector, and stores the code vector " 8 " in the memory unit 25. FIG. The control unit 24 then sends the input code vector " 8 " to the phoneme code generator 26. The phoneme code generator 26 searches the standard code table 27 and checks whether there is a same code vector as the received code vector. Since there is the same code vector, the corresponding phoneme code "17" is output to the auto meta 28. Therefore, the phoneme "ㅁ" corresponding to the phoneme code "17" is displayed on the display device 30.

Subsequently, when numeric key 1 is inputted, code vector generator 22 generates code vector " 1 " which is passed to controller 24. Since the control unit 24 receives the vowel base code vector again while the consonant base code vector is stored in the memory unit 25, the controller 24 resets the memory unit 25 and stores the newly input code vector “1”. Stored in the section 25. At the same time, the controller 24 transfers the input code vector " 1 " to the phoneme code generator 26, and by operation of the phoneme code generator 26, the phoneme code " 51 " corresponding to the corresponding code vector " 1 " Is output. The phoneme code " 51 " is combined with the phoneme code " 17 " in the auto meta 28, so that the phoneme code " 51 "

When the numeric key 2 is pressed for the third time, the code vector generator 22 generates the code vector " 2 " and delivers it to the controller 24. Since the control unit 24 receives the vowel base code vector again while the vowel base code vector is stored in the memory unit 25, the controller 24 sequentially stores the vowel base code vector in the memory unit 25. That is, "1" is stored in the uppermost position of the memory unit and "2" is stored in the lowermost position. On the other hand, the controller 24 first sends the code vector " 12 " by the combination of the newly input code vector and the stored code vector to the phoneme code generator 26. The phoneme code generator 26 accesses the standard code table section 27 to check whether the same code vector exists. As a result of the check, the same code vector exists, so that the corresponding phoneme code "31" is output to the auto meta 28. In auto meta, a phoneme code " 17 " corresponding to a consonant code vector inputted for the first consonant and a newly generated phoneme code " 31 " are combined. The result is displayed as “e” on the display device 30 through the output device 29.

When the conversion key is pressed once, code vector generator 22 generates code vector " 3 " which is passed to controller 24. The control unit 24 also stores the code vector " 3 " for the conversion key while storing the vowel basic code vector in the memory unit 25. That is, the memory unit 25 stores the basic code vectors "1", "2", and "3". Here, the code vector "1" is stored at the highest position, the code vector "3" at the lowest position, and the code vector "2" is stored therebetween. The controller 24 transmits the code vector “123” including the newly input code vector “3” to the phoneme code generator 26 and checks whether the same code vector exists in the standard code table unit 27. In this case, since there is a vector code of "123", the corresponding phoneme code "39" is outputted, and this phoneme code "39" is combined with the phoneme code "17" input by the auto-meta 28 as initial entry. The display device 30 displays "parent".

Next, when the key * is pressed, the code vector generator 22 generates a code vector " * " which is passed to the control unit 24. Since this code vector is recognized as a consonant basic code vector, the memory unit 25 is reset and only the newly input code vector " * " is stored in the memory unit 25. The control unit 24 stores the code vector " * " in the memory unit 25 and transfers it to the phoneme code generator 26. The phoneme code generator 26 accesses the standard code table 27, checks whether there is the same thing as this code vector, and if so, outputs a phoneme code " 21 " corresponding to the code vector. The phoneme code is transmitted to the auto meta 28, and the display device 30 is displayed with "peg".

When the key * is pressed again, the code vector generator 22 generates a consonant code vector " * ", which is also passed to the controller 24. Since the type of the code vector already input to the memory unit 25 and the newly input basic code vector are the same type, the control unit 24 sequentially stores "*" in the memory unit 25. That is, "*" and "*" are stored. The control section 24 sends these code vectors to the phoneme code generator 26. The phoneme code generator 26 checks whether the standard code table section 27 is the same as the "**" code vector. If it turns out that there is no, it checks whether there is an equal to the newly input code vector "*". In the present embodiment, since the code vector of the latter code vector "*" exists, the phoneme code "21" corresponding thereto is output from the phoneme code generator 26. In addition, the auto meta 28 receives the phoneme code "21", and outputs "mummy" to the display device 30 in combination with the previous phoneme code "21".

Subsequently, when the numeric key 1 is inputted, the vowel basic code vector "1" is generated, and the controller 24 resets the memory unit 25, stores the newly input code vector "1", and at the same time, the phoneme code generator 26 Send the code vector "1". Then, the phoneme code generator 26 accesses the standard code table section 27 and checks whether the same as the code vector " 1 " In this example, the code vector " 1 " exists in the standard code table section 27, and the phoneme code generator 27 outputs the phoneme code " 51 " The phoneme code " 51 " is combined with the phoneme code " 21 "representing the previously inputted initial consonant to output " moxy "

Thereafter, the above-described process may be repeated to display an "ugly tree protects the mountain." In order to input a punctuation mark ending the next sentence, the operation mode should be changed from the Hangul input mode to the special character input mode. In this embodiment, the menu key is pressed. When the "menu key" is pressed, the code vector generator 22 generates a code vector "A", and after the control unit 24 receives this value, the control unit 24 detects that the operation mode has been changed to the special character input mode and displays this value. It is stored in the memory unit 25.

Subsequently, when the numeric key 5 to which the special character quotation mark is assigned is pressed, the code vector "5" is generated. The control unit 24 stores this code vector in the memory unit 25 and simultaneously sends the code vector "A5" to the phoneme code generator 26. The phoneme code generator 26 outputs the corresponding phoneme code "A2" and sends it to the auto meta 28. The punctuation mark, which is a special character representing the phoneme code "A2", is displayed on the display device 30 so that the sentence "ugly tree protects the mountain" is completely input.

According to the above description, in the present invention, the terminal sound derived from the 19 consonants forming the Korean consonants of the Korean consonant is divided into 1: 1 to the input key, and the terminal sound is assigned 1: 1 using the consonant input key and the conversion key. The double consonants used in the audible sounds, vowels, and bells derived from are consistently expressed. In other words, to input the consonant "ㄲ" and the consonant "ㅋ" of the basic consonant "ㄱ", press the number key to which the basic consonant "ㄱ" is assigned, and then press the convert key once to convert to the consonant "ㅋ" and convert Pressing the key again toggles to "ㄲ". Therefore, little effort is required to learn consonant input keys. In addition, since only one consonant is arranged in each of the consonant input keys, when inputting a final word composed of two different consonants, there is an advantage that the number of inputs can be considerably reduced.

If the concept of conversion key is extended to the vowel input system, only ㅡ and ㅣ are used as vowel input keys. In other words, to input the vowel, look at the shape of the vowel to be input, press "-" and "ㅣ" according to the handwriting order, and operate only the conversion key. Therefore, it is possible to easily determine which vowel input key to press, in particular, such as "ㅞ", "ㅝ", "ㅖ", "ㅒ", "ㅟ", "ㅘ", "ㅙ", etc. The input process of vowels is convenient.
