ABSTRACT:
A device for sensing the longitudinal edges of an aperture pattern in a longitudinally and transversely moving opaque strip of material includes a transversely moveable platform. Arrays of detector elements are supported on the platform and positioned such that some elements of each array are opposite the aperture patterns and other elements of each array are opposite the opaque borders of the strip. Energy sources are individually arranged on the side of the strip opposite the arrays whereby the elements opposite the aperture pattern receive energy and the elements opposite the borders are shielded. The energy conditions of the elements are detected and the platform is moved transversely to maintain an equal number of elements in both arrays opposite the apertures whereby the platform tracks the transverse motion of the strip.
