Title: Kana and kanji input device
Inventor: NARITA KIYOKAZU
IPC: G06F17/22
Filed: 1985-05-24
Abstract: PURPOSE:To input KANJI (Chinese character) mixed with hand written KANA (Japanese syllabary) without erroneous character since even an erroneous charac ter is inputted but converted to a correct character by providing a reading generating part and a KANA/KANJI converting part in addition to a character recognizing part. CONSTITUTION:When the character such as KANJI, KATAKANA (square form of Japanese syllabary and HIRAGANA (cursive form of KANA) is handwritten at a tablet 1, a coordinate signal is generated and outputted to a character recognizing part 2. The recognizing part 2 refers to a recognizing dictionary part 3 where the information such as the character shape, etc., is stored beforehand, and recognizes the shape of the character from the sent coordinate information. For the recognized, reading is prepared through a reading generating part 4, and the mixed writing of Chinese characters with the Japanese syllabary is prepared by a KANA/KANJI converting part 5. Thus, since the erroneous character is inputted and converted to the correct character, regardless of the character input error by the operator, then the KANJI mixed with the handwritten KANA can be inputted without any erroneous characters, and the correct sentence can be prepared.
