Abstract
In a document processing apparatus, the top position of the input data visually displayed on a display unit is displaced toward the end of the line and the corresponding control code mark is represented before the top position of the input data when a control code therefor is input. The apparatus is provided with a shift inhibit for adding space codes in the corresponding area of the input data buffer so that format is not changed despite rewrite of the control code, and a shift permit for displacement of the top position after erasure of said control code mark by the erase signal. Thereby, deformatting is prevented and the document processing is easily carried out.
