Abstract

Original document registration fingers 1 retractably extend up through only limited holes or notched areas 2 in a stationary feedoff baffle plate 3 at the downstream edge 4 of the platen 5. The baffle 3 extends up to and directly contacts the beveled platen edge 4 except at the finger holes 2 to prevent the document from being caught between the fingers 1 and the rest of the registration mechanism, or caught between the baffle 3 and the platen edge 4. However, baffle 3 is preferably part of the platen cover (not shown) and lifts therewith to clear the corner edge 4 of the platen 5 for book copying. The registration fingers 1 are flexible spring steel strips to maintain continuous pressure against the platen glass beveled edge 4. This also helps prevent a curled sheet from interfering with or being caught at the registration edge 4. Here this is accomplished by partially wrapping the lower portions of the strips 1 around cams 6. The cams 6 are partially
