              Appeal No. 2002-1744                                                                Page 2                
              Application No. 09/179,793                                                                                


                     An operator of a juke box must periodically access the data cartridges contained                   
              therein.  For example, he may need to replace a cartridge that has been filled with data                  
              to be archived at another location.  (Id. at 2.)                                                          


                     To satisfy the aforementioned need, the inventive juke box 12 features                             
              drawers 16 that can be moved between a closed position and an opened position.                            
              Drawer stop indices 78 are coupled to each drawer so as to move along with the                            
              associated drawer.  A lock 80 can be moved between a locked position and an                               
              unlocked position.  When locked, it engages a drawer stop index to prevent the                            
              associated drawer from being withdrawn further.  (Appeal Br. at 2.)                                       


                     A further understanding of the invention can be achieved by reading the following                  
              claim.                                                                                                    
                            36. A mail slot data cartridge exchange system for a data storage                           
                     system, comprising:                                                                                
                            a drawer mounted to the data storage system so that said drawer                             
                     can be moved between a retracted position and a plurality of extended                              
                     positions; and                                                                                     
                            drawer extension regulator means operatively associated with said                           
                     drawer for allowing said drawer to be manually extended to a selected one                          
                     of said plurality of extended positions and no further, while allowing said                        
                     drawer to be manually returned to the retracted position without requiring                         
                     additional actuation of said drawer extension regulator means.
