PURPOSE:To omit shift mode changing operation at the time of correction, to avoid providing of an unnecessary number of memory areas of shift made and to make effective use of a memory by storing input characters and shift modes. CONSTITUTION:Symbols of M1-M4 are allowed to correspond to each shift mode, i.e. hiragana (cursive form of Japananese syllabary), katakana (square form of Japanese syllabary), capital characters of alphabet, and small characters of alphatet. For instance, a (hiragana) i (hiragana) u, e (katakana) o (hiragana) are inputted, symbols M1, M1, M4, M2, M1 that indicate shift modes are inputted to pointers 4e-4a of a character mode buffer 1g. When e (katakana) is to be corrected to o (katakana), a cursor shifting key of the symbols is depressed twice. Then, the cursor comes under e (katakana). The pointer 4f indicates +2. This indicates character mode buffer 4b. The mode changes the shift mode buffer 1h to katakana mode by looking at the content M2 of 4b. When o (katakana) is inputted, o (katakana) is indicated and stored. Thus correction is finished.
