          Appeal No. 95-4595                                                          
          Application 07/927,783                                                      


               Having fully considered the tape cassette guide pin teaching           
          of Tomita (Figure 6) and the record player center pin disclosure            
          of Teragaki (Figure 2), individually and collectively, we are of            
          the view that, absent appellant's disclosure and impermissible              
          hindsight, the applied evidence of obviousness would not have               
          been suggestive of the claimed invention to one having ordinary             
          skill in the art.  It is also readily apparent to us that even if           
          it would have been obvious to modify the guide pin of Tomita, at            
          best Teragaki would have been suggestive of providing the tip               
          portion 51 of Tomita (Figure 6) with grooves to effect four                 
          elastic pieces.  The resulting pin clearly would not evidence a             
          cross-section of a conical portion having the shape of a four-              
          pointed star, as now claimed.  Thus, the applied prior art does             
          not render the claimed invention unpatentable under 35 U.S.C.               
           103.                                                                      


               In summary, we have reversed the rejection of claims 12                
          through 15, 26, and 27 under 35 U.S.C.  103 as being unpatent-             
          able over Tomita in view of Teragaki.
