Abstract: A mechanism is disclosed for the automatic erasing of typing errors utilizing a fully serialized and automated correction apparatus where the correction is accomplished by a single backspace operation allowing both the erasure of the erroneously typed letter and the typing of the proper letter. The backspace operation repositions the typewriter carriage for the correction of the erroneous letter and at the same time inhibits the escapement of the carriage for a single print cycle allowing the corrected letter to be printed over the correction without requiring an additional backspace operation. The escapement mechanism is re-engaged during the correction cycle so that the carriage advances of the print cycle.
