          Appeal No. 1997-2316                                                        
          Application No. 08/329,616                                                  


          After Final (paper number 27), claims 12 and 15 were amended.               
               The disclosed invention relates to a disk loading                      
          mechanism for a recording/reproducing apparatus which can                   
          accept disks of several diameters as well as a disk cartridge.              
          The diameter of a recess in the disk loading mechanism for the              
          disk cartridge is smaller in diameter than the diameters of                 
          the recesses for the disks.                                                 
               Claim 1 is illustrative of the claimed invention, and it               
          reads as follows:                                                           
               1.   A disc loading device comprising:                                 
                    a supporting base having a disc rotating driving                  
          unit      for rotationally driving discs of different                       
          diameters as recording media on which information signals are               
          to be     recorded or are pre-recorded, and a disc                          
          transporting tray for holding and transporting said discs,                  
          said disc           transporting tray being arranged above said             
          supporting base     and being movable between a position in                 
          which it is drawn into an outer casing containing said                      
          supporting base          therein and a position in which it is              
          drawn out of said outer casing,                                             
                    said disc transporting tray including:                            
                    a first positioning recess for holding and                        
          positioning    a first disc having a first diameter, said first             
               positioning recess being formed in an upper surface of                 
          the       disc transporting tray as a circle having a diameter              
                    corresponding to said first diameter, a second                    
          positioning    recess for holding and positioning a second disc             
          having a       second diameter smaller than said first                      
          diameter, said      second positioning recess being formed in a             
                                          2
