ABSTRACT:
A drive system for slides and x-y stages in microscopes and similar instruments having the possibilities of both fine control and rapid displacement of the slides over larger distances. The drive system comprises a friction wheel and a friction track provided between the slide and the stationary slide guide. A friction wheel together with an actuation knob are solidly fixed on a common shaft and this common shaft is displaceable against a spring force so that the friction wheel is out of contact with the friction track.
