Abstract
The keyboard of an electronic typewriter with a daisywheel print unit on a carriage includes a CENTER key and REPEAT key. With the print unit positioned where an insertion is to be made in a line being set up blind, these keys are actuated and the character to be inserted are typed in. The usable area for typing is continually shown on a two-digit display device. When a service key is then depressed, the line is printed with the inserted character entered by appropriate compression or expansion of empty spaces adjacent the characters to be inserted. The typewriter further comprises a line space memory and a control circuit which signals the number of line spacing commands which can still be carried into effect before the last line to be typed on the sheet.
