ABSTRACT:
In an electronic correcting typewriter, a character correction and replacement system is disclosed for facilitating the task of correcting typed character errors. The typewriter includes a printing and a correcting mechanism operated under electronic control and a correction buffer is associated with the electronic control for storing the last plurality of printed characters. To automatically erase any previously printed character which character has its code stored in the correction buffer and print a new replacement character, the typist locates the carrier opposite the unwanted character and actuates the character key of the desired replacement character. Under control of the electronics, the unwanted character code is recalled from the correction buffer, the correcting mechanism is operated to erase that character and the printing mechanism is operated to print the new character. Operator setting of an overstrike flag provides character overprint capability.
