<p>An electronic typewriter comprises a character-bearing disk movable along the platen and a selector to space selected characters according to a plurality of constant spaces or proportional spaces. The electronic unit provides a line buffer on which the entered character of a line are sequentially stored and a series of editing functions selectable directly from the keyboard and automatically executed by the machine. A permanent, alterable memory has a series of registers, wherein are recorded positioning information for the disk and constant phrases to be printed upon recording command of the operator. A series of keys are operable to select associated registers of the memory to execute the movement of the disk or the printing of the recorded constant phrases, as recorded, Justification of a line is commanded by a selector which allows the printing of entered characters up to a set zone of the printing line whilst stores, without printing, the remaining characters on the line buffer. Following actuation of a service key causes the delayed printing of stored part of the line, expanding spaces between words up to aligning the margin of printing line to the fixed right margin. A centering key stores, without printing, the entered characters of a title whilst following printing will occur upon actuation of the new line key, centered with respect to a set point of the line. An evidence selector is further operable at any point of the printing line to cause an evidence of printed character as bold-facing or underlining and a cancel key is provided to automatically cancel the characters printed along the printing line with or without evidence, either from the sheet of paper and from the line buffer.</p> |
