          Appeal No. 1997-3478                                                        
          Application 08/397,648                                                      


          reference to Fujita fails to teach or suggest at least the                  
          feature of a disc cassette and shutter where the disc housing               
          has an angled back wall as defined in claims 1 to 6 on appeal.              


               Representative independent claim 1 is reproduced below:                
               1.  A disc cassette comprising:                                        
               a case in which a disc-like recording medium having an                 
          information recording area is rotatably received, said case                 
          having an opening through which at least a part of said                     
          information recording area of said medium is exposed;                       
               means for defining a rectangular recess on a front area                
          of said case where said opening is positioned, said                         
          rectangular recess being defined by two opposed side walls, a               
          back wall and a bottom wall, said back wall being oriented to               
          face forward; and                                                           
               a shutter slidably engaged with said rectangular recess                
          in a manner to selectively open and close said opening, said                
          shutter being slidable in a direction parallel to a direction               
          in which said back wall extends,                                            
               wherein said back wall of said rectangular recess has a                
          surface inclined relative to said bottom wall, said back wall               
          and said bottom wall forming an obtuse angle, and wherein a                 
          height of said back wall defines a depth of said rectangular                
          recess, said depth being greater than a thickness of said                   
          shutter.                                                                    
               The following reference is relied on by the examiner:                  
          Fujita et al. (Fujita)             5,084,862           Jan. 28,             
          1992                                                                        
               Claims 1 to 6 stand rejected under 35 U.S.C. § 103.  As                
                                          3
