DOCUMENT PROCESSOR

PURPOSE:To increase the picture display speed and to improve the operability of a document processor when characters are deleted consecutively, by providing a buffer for KANA (Japanese syllabary)/KANJI (Chinese character) unfixed characters in combination with an input buffer pre-reading control part. CONSTITUTION:Codes sent from a keyboard 1 are supplied to an input code analyzing part 3 via an input buffer 2. The part 3 analyzes the code read out of the buffer 2 and pre-reads the character control codes like a regress code, a deletion code, etc. out of othe buffer 2. These character control codes are given to a cursor shift control part 5 for control of the cursor position. While a text code control part 12 obtains the character control code from the part 3 and controls the contents of a text code memory 8. A display control part 4 receives the picture control signal from the part 3 and segments the contents of the memory 8 to supply them to a display device 9.
