Abstract

Abstract A system for controlling a drive mechanism to selectively move a work member from an existing position to a desired position. The system includes a probe-like sensing member adapted to engage and be moved by the work member. The sensing member is operably connected to a signalling mechanism adapted to produce an output signal related to the position of the work member. A position selecting assembly including at least one selector unit adapted to be selectively pre-set corresponding to a desired position and to produce an output signal related thereto. A position indicating assembly is operably connected to the signalling mechanism and the position selecting assembly being adapted to receive the respective output signals therefrom and produce a different signal related to the variation between the existing position to the desired position of the work member. A signal analyzing assembly is operably connected to the position indicating assembly for analyzing the output signal thereof and for producing an output signal to activate the drive mechanism in response thereto to move the work member from the existing position to the desired position.
