Abstract
A monoaxial coarse-fine adjusting apparatus for optical instruments has a pair of friction wheels whose peripheries are in engagement with the fine adjusting shaft. The axles to which the friction wheels are mounted are received in slots formed in the coarse shaft. The coarse adjusting knob has a surface which the friction wheel axles bear against. A pair of springs are provided which accommodate for torsion and backlash. Rotation of the coarse knob directly rotates the coarse shaft. Rotation of the fine knob rotates the friction wheels in a planetary fashion. The friction wheel axles which are received in the slots in the coarse shaft, drive the coarse shaft an amount which is proportional to the rotation of the fine knob.
