Abstract: The invention contemplates improved means of control for a copy holder, for example, a roll-operated positioning device for a data draft or the like sheet to be copied by a typist, so that the eye can be guided correctly on a line-by-line basis. The improved control provides precise electric-motor drive for each of a plurality of selected different paper-displacing increments, at least one of the increments being selectively adjustable to exactly match the line spacing unique to the particular paper from which the copy is to be made.
