Abstract
An x-y positioning device in which a cable or chain is used to drive a carriage, powered by two motors. The same cable that moves the carriage also constrains the angular orientation of the moving mechanism. In so doing, the moving parts can be made lighter and less expensively, while providing improved dynamics. All is advantageously applied to large, flat-bed plotters, to a computerized engraver, to a large sign painter, or to an elevator.
