KANA CHARACTER INPUT METHOD AND KEYBOARD EMPLOYING THE SAME

PROBLEM TO BE SOLVED: To provide a method by which 85 kinds of KANA characters can be easily and promptly inputted by typing 26 keys for alphabets once or twice.SOLUTION: Fourteen KANA characters representing sounds of rows of KANA, one KANA character representing a small letter sound, five KANA characters representing vowels and six KANA characters representing palatalized syllable, double consonant, the Japanese syllabic nasal and long vowel are assigned to totally 26 keys one by one. By combining keys for sounds of rows of KANA and keys for vowels, one KANA character from ka-row to wa-row is outputted and by combining a key for small letter sound and a key for vowel, one KANA character in a-row is outputted. By combining a key for sounds of rows of KANA and a key for palatalized syllable, two KANA characters with palatalized syllable are outputted and KANA of a-row, double consonant, and the Japanese syllabic nasal are inputted by typing a single key displaying a desired character thereon. Even on a small-sized keyboard of mobile equipment or the like, two keys can be simultaneously types by using both hands or two fingers of one hand regardless of the order, thereby achieving an input speed as high as simple and prompt touch typing of alphabet keys.
