ABSTRACT:
Precision positioning apparatus includes a rotatable driving element connected to a rotatable driven element having a diameter substantially greater than that of the driven element, and rotary movement of the driving element imparts rotary movement to the driven element. The diameters of the two elements are related so that a relatively large movement of the driving element results in a relatively small movement of the driven element, and vice versa.
