Abstract (en)
[origin: US4382702A] A word processing machine for printing text in the form of successive lines of characters on a record carrier and including a printing mechanism constructed to operate with interchangeable typing elements, each typing element carrying a selected set of type characters each corresponding to a respective character representation, a function keyboard for effecting input of first and second function instructions, input of the first instruction being effected when character representations are to be inputted which correspond to type characters carried by another typing element; and a control unit responsive to the first function instruction for temporarily preventing printing of characters corresponding to character representations subsequently inputted via a character input keyboard and for storing each character representation together with the first function instruction in the memory in a manner to indicate the intended location of the associated character on the record carrier, while causing the printing mechanism to leave a blank space at that intended location, and responsive to the second function instruction, after the other typing element is introduced into the printing mechanism, for causing readout from the memory of the character representations stored together with the first function instruction and printing of the associated characters at the respective intended locations on the record carrier.
