Abstract
The invention contemplates selectively engageable/disengageable coupling mechanism within the respective drive trains which impart two-component displacement to a mechanical stage such as a microscope stage. For each component of drive, a pressure roller is selectively interposable between a drive-side friction wheel and a driven-side friction wheel which are engaged only when the pressure roller is in loaded contact with both of these wheels.
