Zusammenfassung:	A multi-element writing instrument is disclosed for use in computer-operated plotters or similar graphics systems. Successive applications of a linear force applied along the axis of the instrument are converted to rotary motion which is employed to select successive elongate writing elements normally positioned at a uniform radial spacing from the axis of the writing instrument. Each selected element is displaced in a substantially axial direction a distance sufficient to extend the writing point of the element through the exit opening of the instrument.
