Abstract
An X-Y movement mechanism, having right-handed and left-handed lead screws arranged in parallel with each other and drive sources for individually rotating the lead screws. Gears placed over nuts engage the lead screws, the gears having teeth coaxially with said nuts. A base plate, either flat or cylindrical has a stage slidable thereon. A rack is fixedly provided on the stage to engage the gears. The gears operate as a gear transmission mechanism permitting the rack to move in a direction perpendicular to the direction of the axes of the lead screws and in the direction of the axes of the lead screws.
