10 snapped into position over an upper disk surface and concludes
that it would have been obvious to “provide the hub of Kikuchi
with a snap action type hub as taught by Azuma” because “the
resilient snap action provides a secure fit while also allowing
for easy removal of the hub” [answer-pages 3-4].
The “claw” 10 of Azuma is actually a spring loaded
chucking mechanism that fits over the top surface of the disk
while protruding part 9 acts as a stopper ledge for effectively
clamping the disk. But, in any event, neither element 56 of
Kikuchi nor element 10 of Azuma is “formed in said wall portion”
and “project[ed] from said outside peripheral surface of said
cylindrical wall” in such a manner as to render “said first wall
portion flexible so that said first wall portion is elastically
displaced radially inwards to a deformed position to allow said
center core to be attached to said optical disk . . . ,” as
claimed.
The majority appears to take the teachings of Azuma
