1. An apparatus for scanning data encoded in bit form on a planar data strip, said data strip having a series of data lines of bit areas running transversely across said strip, said data lines being parallel to, contiguous with, and conterminous with, each other, whereby the totality of said lines defines the length of said strip, said encoded data being sequentially encoded along each said data line and thereafter along the contiguous said data line,said apparatus including,a chassis adapted to be positioned proximate to said data strip,a first cylindrical lens mounted on said chassis parallel to the plane of said data strip and parallel to said data lines, and means for moving said chassis longitudinally of said strip,at least one second cylindrical lens mounted in said chassis parallel to the plane of said data strip and perpendicular to said data lines, and means for moving said second lens transversely along said first lens,a detector mounted on said chassis at the focal point of said lenses relative to said data strip,whereby bit areas on a given said data line are focused in sequence on said detector and said data lines are focused in sequence on said detector.
