摘要：A mechanism is disclosed for the automatic erasing of typing errors utilizing afully serialized and automated correction apparatus where the correction isaccomplished by a single backspace operation allowing both the erasure of theerroneously typed letter and the typing of the proper letter. The backspace operationrepositions the typewriter carriage for the correction of the erroneous letter and at thesame time inhibits the escapement of the carriage for a single print cycle allowing thecorrected letter to be printed over the correction without requiring an additionalbackspace operation. The escapement mechanism is re-engaged during the correctioncycle so that the carriage advances of the print cycle.
