Abstract
Control apparatus for controlling or adjusting the position of a control member is disclosed. The control apparatus includes first and second members, pivotally connected together to pivot about a point. A control member is mounted on the first member and is disposed at a first distance from the pivot point. Coarse control means operatively associated with the control member are provided for coarsely adjusting the position of the control member relative to the second member. Further, fine control means are provided for finely adjusting the position of the control member relative to the second member. The fine control means acts at an action point on one of the first and second members to pivot the first and second members relative to each other about the pivot point. The action point at which the fine control means acts is a second distance from the pivot point which is greater than the first distance such that a selected amount of movement of the action point results in a change in position of the control member relative to the second member, the amount of change in position being less than the selected amount of movement.
