ABSTRACT:
An improved joystick controller is disclosed in which the controller has a handle which is pivotally mounted in a base. An electrical cord carries the signal generated by the joystick controller from the base. The improvement comprises a ring and a spacer for positioning the ring spaced apart from the base. An outer housing encloses the base, the spacer and the ring with the housing having a substantially planar surface. The substantially planar surface has a radius of curvature which is greater than the outer ring of the ring. A cylindrically shaped member is mounted near the center of the planar surface. The member has a radius of curvature less than the inner radius of the ring and is positioned such that the ring passes through the member and rests on the surface. Thus, the rotation of the handle about its pivotal axis causes the cord to be wound or unwound about the spacer in the housing.
