Abstract

Abstract An improved document easel preferably for use with video display terminals, has a generally L-shaped bracket and a generally U-shaped member removably attached to the video display terminal. The generally L-shaped bracket is rotationally connected to a base member of a generally U-shaped bracket such that the U and L shaped brackets rotate with respect to each other about an axis of rotation that is generally perpendicular to the U-shaped bracket base member. A pair of arm members extend out from the U-shaped member and are attached to a document easel so as to provide rotational movement between the U-shaped member and the easel about an axis of rotation that is generally parallel to the base member of the U-shaped member. A hollow tube and rod combination provide a selectively adjustable tension/compression arrangement, thereby allowing reorientation of the easel relative to the video display terminal.
