The present invention relates to a keypad device, and more particularly, to a keypad device in which key buttons are arranged in a matrix form so that letters and numbers can be input.

Devices that generate numbers and letters, that is, recognize the meaning of input keys and generate corresponding standard codes, are actively used in information processing devices such as computers and various communication devices. Among them, a computer or the like that needs to process a large number of letters and numbers at high speed employs a relatively large number of about 100 keys, so that the user's key manipulation for generating letters / numbers is simple and easy. However, since portable information communication devices such as mobile phones generally employ only about ten, typically twelve basic keys and several function keys due to space constraints, a method of generating various letters and numbers through them is Inevitably complicated.

FIG. 1 is a front view showing the appearance of a terminal to which a numeric / character keypad in which key buttons are arranged in the form of a conventional four-row and three-column, and is particularly proposed as a device for generating Korean characters, alphabets, and numbers.

As shown in Fig. 1, the conventional numeric / character keypad configuration has a function provided with a numeric / character keypad 130 and several function key buttons, each of which is provided with twelve key buttons (keys) necessary for representing numbers and characters. The keypad 120 can be roughly divided. The number and arrangement of key buttons belonging to the numeric / character keypad 130 are internationally standardized with respect to numbers and alphabet input. On the other hand, a liquid crystal panel 110 or the like as an output unit for displaying the processed result is disposed above the keypad.

In the keypad device shown in Fig. 1, the 130 key button of the numeric / character keypad has at least one or more numbers, each of Korean alphabets (consonants and vowels) and alphabets (English characters) of the universal language on or around the surface. It is arranged in pieces so that it is complicated to use.

In such a configuration, when a number is to be entered, it is sufficient to press the key marked with the desired number once. However, if you want to enter the Hangul word 'love', first press the key button marked with the number 8 for the consonant 'ㅅ' that constitutes the syllable 'Sa' with the operation mode set to Hangul mode. You must press the key button marked number 1 once and then the key button marked number 2 once. Next, press the key button marked with the number 5 twice (b-> ㄹ) for the first consonant 'ㄹ' constituting the syllable 'rang', and press the key button marked with the number 1 once for the neutral 'ㅏ' You must press the key button marked number 2 once, and finally press the key button marked number 0 for the final 'ㅇ'.

On the other hand, the above-described numeric / character keypad is manufactured and shipped differently for each manufacturer consonant and vowel arrangement of the Hangul consonants and vowels, so that the matrix form with reference to Figures 2a to 2e for clarity. Explain.

Therefore, in the case of consonants, it is achieved by pressing the key button to which the consonant is assigned once or by pressing the shift key button first, and then pressing the key button to which the consonant is assigned. In particular, in the case of letters without support, the 'Finish' key button must be pressed to write the next letter. For example, in the case of 'I love you', you can press the corresponding consonant and vowel keys in the order of 'ㅅ-> ㅏ-> ㄹ-> ㅏ-> ㅇ-> ㅎ->' '. 1 key button, 'ㅏ' means 1 row and 3 column key buttons, 'ㄹ' means 4 row and 1 column key buttons, 1 time, 2 rows and 1 column key buttons, and 'ㅏ' means 1 row and 3 column keys. 1 time, 'ㅇ' is 1 time, 3 row 2 column key button, 'ㅎ' is 4 times, 2 column key button 1 time and 'ㅐ' is 1 time, 3 row key button 1 time Is achieved by pressing.

As described above, the conventional numeric / character keypad not only takes a long time to find a desired key, but also requires a number of key manipulations to generate unit phonemes.

On the other hand, in the case of English letters, all five types are written in the same way. This is because 12 internationally standardized key buttons are used. If you want to input English word 'LOVE', the operation mode is alphabetic mode. With the number 5, three times in a row, the number six with a key three times, the number eight with three keys consecutively, and the last number three with three keys consecutively. . Of course, after each phoneme is generated, a signal indicating the end of input of the corresponding phoneme, for example, a constant time gap signal between the phoneme and the phoneme, must be input. As a result, in order to generate the English word 'LOVE', a total of 14 key operations are required in addition to a function key operation such as mode selection.

In order to improve such a cumbersome and difficult to use numeric / character keypad, an improved numeric / character keypad is disclosed in Korean Patent Publication No. 8007 in 2003 with a one-to-one correspondence of the alphabet to the seven-row and four-column key buttons.

The above-described improved numeric / character keypad can be easily and quickly written in English by assigning one alphabet to one character key. By using a character key to recognize, it is possible to operate a plurality of character keys and numeric keys in a small space. In other words, when the number 1 is input, it is recognized by pressing two or more of the four keys of the letter key buttons 'A', 'B', 'E' and 'F'.

As described above, according to the conventional numeric / character keypad apparatus and the improved numeric / character keypad apparatus, the conventional numeric / character keypad apparatus has a problem of having a large number of strokes and a long fingering distance when writing English and Korean characters. In the case of the keypad, the number and the English writing were conveniently improved, but the Korean writing was not supported.

The present invention has been made to solve the above-described problems, by placing four consonants and vowels in four rows and four columns on the numeric / character keypad with a large number of key buttons improved the number and English writing more conveniently, The purpose of the present invention is to provide a keypad device for writing Korean characters with fewer strokes and a short fingering distance.

Keypad device of the present invention for achieving the above object is at least one consonant or vowel of the Hangul correspondence, a plurality of character key buttons having a matrix form of at least four rows and four columns arranged at a predetermined interval therebetween and It is provided at the predetermined intervals, and provides a keypad device comprising a plurality of numeric key buttons formed in a relatively recessed form compared to the character key button.

Hereinafter, a keypad device according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As is well known, letters are roughly divided into phonetic letters and ideological letters according to whether or not the meaning is given to the syllables, and the phoneme letters and syllable letters are divided depending on whether the phoneme can be divided into phonemes. Representative characters of the phonetic alphabet include Korean alphabet and alphabet, and representative characters of the alphabet include Chinese. Representative syllables include Japanese, and phoneme characters include Hangul and the alphabet.

On the other hand, the types of characters may be distinguished depending on whether the form of the character is hierarchical or hierarchical. The representative case of the hierarchical character is alphabet, and the representative case of hierarchical character is Hangul. In the following description and claims, 'character' is used to encompass phonemes or syllables, and 'phoneme' is used to specifically refer to the minimum unit of composition that each character has. Thus, according to this definition, 'a', 'b', etc. in the alphabet may be phonemes, and in Korean, 14 consonants and 10 vowels will be the basic phonemes. In particular, in the case of Hangeul, each phoneme is divided into consonants / vowels for clarity of explanation, and one sound (double consonant) or double vowel (double vowel) is also expressed as phonemes. The term 'syllable' may be used to mean. According to this definition, in the word 'Hangul', 'Han' and 'Wang' will each correspond to a syllable. In addition, it should be noted that 'symbol' is used to mean all possible recognition marks other than letters and numbers, and 'set of letters' is used to mean all phonemes that make up the letters of the country. . Thus, according to this definition, a set of alphabet letters means a total of 26 phonemes, ranging from 'A' to 'Z', and at least the consonants 'ㄱ' to 'ㅎ' and the vowel 'ㅏ' to 'l' A total of 24 phonemes or old and double vowels are included.

In addition, the terminal includes various information inquiries such as a computer, a calculator, an electronic dictionary, a mobile phone, a PDA, etc. that can receive and process numbers, letters, and symbols, and a key input device such as a remote controller and a keyboard. Refers to wired / wireless devices.

In addition, the number of strokes refers to the number of key button presses, and the fingering distance refers to the distance to move a finger to press another key button after pressing any key button.
