An indication is delivered from an input part for decision of paragraphs after the input is through with the sentence. Then a paragraph deciding part decides automatically the paragraphs at and after the head of the input KANA characters and based on a code stored by the space key operated in an input mode of the KANA characters and a paragraph dividing character. Then these decided paragraphs undergo successively the KANA/KANJI (CHinese character) through a KANA/KANJI conversion part.
