International ClassG09G 005/08AbstractAn assembly utilizable with a digitizer cursor for increasing the accuracy of position determinations, wherein the cursor has cross-hairs for enabling the positioning of the cursor at a desired point on a digitizing surface, comprises in combination a magnifying lens and a connector for mounting the magnifying lens to the cursor in a region near the cross-hairs of the cursor. The connector includes a cradle or holder attachable to the cursor and a mounting arm connected to the lens, the cradle and the mounting arm being releasably connectable to one another. The mounting cradle is attachable exemplarily by adhesive to an outer housing surface of the cursor in a region near the cross-hairs. The mounting arm is integral with the lens, the lens having a polished surface and the mounting arm having relatively rough, unpolished, surfaces. Coacting locking elements are provided on the cradle and the mounting arm for releasably locking the lens in a predetermined position with respect to the cursor.Other References
