PURPOSE:To improve the input speed leaps by bounds and to simplify the operation and to reduce the capacity and the weight of a keyboard considerably by inputting all Japanese characters of voiceless sounds, voiced sounds, and p-sounds with only 21 keys. CONSTITUTION:With respect to the arrangement of keys, characters are separated to vowels and consonants and are arranged in individual groups; and Romajis (characters written in a method of writing Japanese in Roman characters) and Kana (Japanese syllabary) characters ''aA'', ''iI'', ''uU'', ''eE'', and ''oO'' are displayed on individual keys in the right column in the alphabetic order to arrange keys of vowels as a vowel group 1. Keys of consonants of voiceless sounds are arranged in the second and the third columns with displays of series of the Kana syllabary and Romajis, and ''k series K'', ''s series S'', ''t series T'', ''n series N'', ''h series W'' are displayed on these keys in order. In this case, consonants are pronounced generally as ''H'' in Romajis with respect to an h series, and ''fu'' is in an h series, but it is pronounced as ''FU'' in the Romaji; and therefore, ''fu F'' is displayed on the key, and this key is arranged adjacently to the key of ''h series H'' to provide facilities for the use. |
