Abstract
A device for moving an object, such as a sheet of paper or other substrate, includes a base element, a drive mechanism to move the base element in first and second directions, such as by vibration, and a plurality of flexible ratchets fixedly secured to the base element. As the base element vibrates, the ratchets advance the sheet of paper in a direction perpendicular to the direction of vibration of the base element. Pluralities of base elements and drive mechanisms can be provided to direct movement of the substrate in various directions.
