Abstract
An assembly utilizable with a digitizer cursor for increasing the accuracy of position determinations made by the operator is disclosed. The assembly comprises in combination a magnifying lens and a connector for attaching the magnifying lens to the cursor in a region about the cross-hairs of the cursor. The connector includes a retainer that is attachable to the cursor and a pivot connected to the lens. The retainer is adapted to be affixed to a surface of the housing near the viewsight of the cursor. The hinge includes a stop adapted to hold the lens parallel to the plane of the cross-hairs. The hinge also includes a cam surface that provides friction between the hinge and the cursor so that the lens is held away from the region above the cross-hairs when the lens is swung away from the viewsight by the operator.
