Abstract

When a carrier of an electronic typewriter is positioned between existing lines of text, unnecessary use of text memory is avoided through not inserting any movements of the carrier into the memory unless a non-paper movement key is activated. To correct text on a previous line of a sheet of paper, it is usually necessary to perform both horizontal and vertical movements of the carrier to reach the location at which the correction is to be made. Since a vertical paper movement key moves the paper only one- half the distance that the paper is moved by a carrier return, the operator often has the carrier between existing lines on the paper; the movement of the paper is the vertical movement of the carrier relative to the paper since the carrier is stationary in the vertical direction.
