<p>The compass has two compass blades (ZS1, ZS2) hingeably connected with each other at respective lower ends. Each blade includes a carrier zone in the form of an extension, which serves as a basis of a compass disk shaped information carrier surface (12) in a region between a blade hinge and free blade ends. The surface is provided on a broadside of the compass and is formed as a simple surface that is projected from one of the blades into a region of another blade, where the surface permits opening and closing of the blades without forming a gap or an intermediate space in the surface.</p> |
