Abstract
A visual positioning system integrated into a magnification device for use for amplifying the size of materials being scanned, can be manipulated to furnish greater length dimension to the material scanned, by shifting and pivoting of either its miniaturized television camera, or the reflecting mirror that scans the camera pickup downwardly onto the textual material being reviewed. The mirror may be pivoted by various structures including a thumb wheel, that cams the mirror into different angular relationships relative to its associated camera, in order to enhance the length of the materials being reviewed and projected onto the television monitor.
