Estimating the term…
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.
A control mechanism for controlling a justifying typographic apparatus having a carriage, for assuring the performance of a sequence of steps in an operational cycle which is determined by (i) a first step of said carriage for correspondingly shifting a print point in a line, and (ii) a last step in said sequence comprising a carriage return step in said line, said typographic apparatus comprising means for producing justification data corresponding to said line, comprising manually operable control means for actuating said means for producing justification data, said manually operable control means being shiftable between an "on" position and an "off" position, locking means coupled to selectively lock said manually operable control means, actuating means operatively connected to said locking means for bringing the locking means into locking position in response to said first step of an operational cycle, latch means operatively connected to said locking means for latching said locking means in said locking position and release means for releasing said latch means in response to the last step of said operational cycle, whereby change of the operational state of said means for producing justification data is inhibited in steps of said sequence between said first step and said last step.

In a typographic composing apparatus having means for recording information on a recording medium, a plurality of first manually operable controls at least some of which correspond to characters and are coupled to actuate said recording means for recording information on said recording medium, each of said controls being arranged to advance a print point on said recording medium at which next received information will be recorded, carriage return control means operable to separate information recorded on said recording medium into groups of recorded information corresponding to separate lines, and conditioning means operable in response to operation of said manually operable controls and said carriage return control means for producing conditioning data corresponding to said lines, said conditioning means comprising second manually operable control means having an "on" position in which said conditioning means is operative to produce conditioning data and an "off" position in which said conditioning means is not operational to produce conditioning data;
