Abstract

A novel error correction system applicable to any type of typewriter or printing apparatus having a ribbon with an appropriate strip for obliterating printed letters, comprises a correction key which is simultaneously associated (1) with the ribbon-position selection mechanism by means of a lever that, through the action of a spring, pulls the ribbon vibrator link to the correction position (2) with the escapement mechanism by means of a link which causes the escapement impeller to move, thereby removing it from the normal operating position and (3) with the backspacing system of the typewriter by means of a surface of the reverse lever which, by acting on a link screw, operates the backspace dog and therefore the typewriter carriage backspaces one space. When the correction system is engaged, however, the escapement impeller remains free to be operated if desired by a space bar.
