<p>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(s) to be inserted are typed in. The usable area for typing is continually shown on a two-digit display device. When RETURN (NEW LINE) or INDEX (new line without line feed) or TAB is then depressed, the line is printed with the inserted character(s) centered in the space available, with compression of the gaps at the left and right ends of the space, and the gaps between words, if necessary. Provision is also made for centering of a table to be printed, display of number of line spacings still possible (altered when line space pitch is changed), and non-volatile storage of tab stops and margins.</p> |
