ABSTRACT:
A scanning device carried on a slide has a section which is movable relative to the slide in the direction of slide movement and in a focusing direction transverse to that direction. An actuator controls both directions of relative movement during normal scanning. To permit free movement in the focusing direction without friction during periods of high acceleration or deceleration of the slide, a mechanical stop limits the relative movement in the direction of slide movement. To prevent friction from impeding focusing movement, the stop is compliant in the focusing direction.
