ABSTRACT:
An automatic system for inspecting products having an edge or edges which, for an acceptable product, are straight (within predetermined tolerances) without accurate orientation of such products which includes a raster-scanned television camera (or its equivalent) for generating a composite video signal corresponding to the product being inspected. The number of horizontal sweep intervals in each edge to determine its length and comparing such length information with pre-stored reference length to determine if the two correspond, rejecting the capsule if it is shorter than the reference length but, if it is longer than the acceptable length, determining if the greater length is a result of the product's being tilted or torn.
