A desk top justifying text writing composing machine including automatic encoding and reading control means for operating a desk top justifying reproducing machine, or for operating larger and more sophisticated printing machines capable of automatic justification. The machine will produce unjustified typed lines and will automatically encode for controlling another machine to print justified lines, as a result of a single series of manual keyboard composing operations and automatic code controlled reproducing operations for producing a justified copy of a literal text, respectively. The machine includes a delete key and automatic deleting and back spacing means that reverses the machine and deletes codes from a code medium according to previously encoded information for back space correction purposes. The machine operates much like a normal office typewriter and may be operated by a person with a little more than normal typewriting skills for encoding a justified corrected text and function control codes. The operator need not be concerned with the set width of characters or spaces in order to back space and delete, since the deleting and back spacing is performed accurately and automatically upon depression of the single delete key. Coordinated back spacing of the literal text operations, reversing of functions and automatic deleting of the individual respective codes is performed automatically in accordance with the codes previously encoded and then being deleted on the code medium. Thus, there can be no error between the forward and delete operations.
