          Application No. 08/147,793                                                  

          image pick-up surface can be maintained constant even if the                
          image magnification is continuously changed by zooming."                    
               From our review of Suzuki, we find no teaching or                      
          suggestion of the claim language “whereby the light from said               
          object of the image passes freely through an optical                        
          discriminator and into a pupil and light from a source, said                
          source appearing in a field-of-view of imaging optics, is                   
          blocked at a discriminator optic and does not pass into the                 
          pupil of the imaging optics.”  The examiner has not pointed to              
          any teaching or disclosure in Suzuki, or advance any line of                
          reasoning that would suggest that the optical apparatus of                  
          Suzuki was capable of meeting the limitations regarding the                 
          claimed optical discriminator.  Accordingly, we find that the               
          examiner has failed to establish anticipation of independent                
          claims 1 and 7, as well as dependent claim 4, by Suzuki.  The               
          rejection of claims 1, 4, and 7 under 35 U.S.C. § 102(b) is                 
          therefore reversed.                                                         
               We turn next to the rejection of claims 2, 3, and 5 under              
          35 U.S.C. § 103 as unpatentable over Suzuki considered with                 
          Kino.  The examiner merely relies upon Kino for a disclosure
