Abstract
An apparatus for moving a driven member, such as a stage, in response to inclination of an operating member, such as a joy stick, produces signals that are transformed between different coordinate systems, such as rectangular and polar coordinate systems, one of the signal transformations being nonlinear. By virtue of the invention, the velocity of the driven member, which is dependent upon the inclination of the operating member, does not depend on the direction of inclination of the operating member, and the direction of movement of the driven member corresponds accurately to the direction of inclination of the operating member.
