          Appeal No. 1998-0454                                       Page 4           
          Application No. 08/417,985                                                  


          arresting condition by the arresting mechanism.  Rather, the                
          transmission member (131 in Figure 2) moves the trigger member              
          (285 in Figure 16) and the trigger member operates the tape                 
          feeding direction change-over mechanism (126 in Figure 1).  The             
          cancellation of the arresting condition depends on whether one              
          of the first or second operating members (108, 109 in Figure 1)             
          is advanced while the other operating member is arrested or the             
          reel receiving elements stop with the other operating member                
          being arrested.                                                             


               Thus, it is clear that an error occurred in the patent                 
          which makes the original patent either wholly or partly                     
          inoperative or invalid.  Appellants have declared that the                  
          error occurred without any deceptive intention and the examiner             
          does not contend otherwise.  Thus, it is clear to us that the               
          error in claim 1 of the original patent is of the type                      
          permitted to be corrected by 35 U.S.C. 251.  We are in                      
          agreement with appellants that what they are doing is                       
          correcting a clear mistake which is precisely the purpose of                
          the reissue statute.
