          Appeal No. 2000-0229                                                        
          Application No. 08/603,005                                Page 18           


          plurality of push button switch sensors instead of the optical              
          sensors of Hellsberg since these are well known equivalents for             
          machine reading of codes defined by holes or apertures.”                    
          Although we agree with the examiner to the extent that the use of           
          push button switches are known, claim 4 additionally requires               
          that the push button switches extend through the apertures to               
          provide the signals, which is not taught or suggested by the                
          prior art.  Thus, we find that the examiner has not addressed all           
          of the limitations of claim 4, and has therefore failed to                  
          establish a prima facie case of obviousness of claim 4.                     
          Accordingly, the rejection of claim 4 under 35 U.S.C. § 103(a) is           
          reversed.
