Abstract

Abstract An apparatus for the automatic adjustment of the inclination angle of a keyboard during use by an operator. The unit operates by a motorized camshaft raising and lowering the back end of a hinged platform that supports a computer keyboard or other input device. The rate of change of the inclination angle and the inclination height are adjustable by the operator. The apparatus is useful in the prevention or alleviation of the effects of repetitive motion disease or carpal tunnel syndrome.
