PURPOSE:To improve the input speed and to reduce the fatigue of a user by providing plural specific shift keys operated with his thumb and omitting key depression when Kanji (Chinese character) read in Japanese pronunciation and a Kana (Japanese syllabary) character string consisting of two or more characters are inputted. CONSTITUTION:On a keyboard device, each keyboard operated by fingers of the right or left hand is arranged to spread out like an unfolded fan so that it is easy to operate, and each key is not linear but is stepped in accordance with the length of the corresponding finger and is arranged arcuately. A consonant shift key 3, an abbreviation input shift key 5, a numeric input shift key 6, and a symbol input shift key 7 are provided under a vowel keyboard 1 and consonant keyboard 2 and are operated as specific shift keys. That is, two- syllable components of a Kana character string or Kanji read in Japanese pronunciation to be inputted are inputted representatively by two simultaneous depressions of the specific shift key and a vowel key on the keyboard 1 by fingers of right and left hands after depression of a consonant key on the keyboard 1. Thus, the number of key depressions is reduced to improve the input speed and reduce the fatigue of the user.
