Appeal No. 2006-1281 Page 6
Application No. 09/926,029
We turn our attention now to the rejection of claims 8 and 9 as being
unpatentable over Watanabe or Kanai in view of Haraguchi or Haraguchi in view of
Watanabe or Kanai. The appellant’s only argument as to why the subject matter of
claims 8 and 9 is not unpatentable over these references is that none of the cited
references “teaches, mentions or suggests” the feature “each said recess forming a
thinner, more flexible portion of the wall than portions of the wall between at least two of
said recesses” (brief, page 10). The same reasoning that supports appellant’s position
with regard to the written description rejection, discussed above, supports the
examiner’s position with respect to the obviousness rejection, as explained below.
Watanabe discloses a tubular ribbon-winding core 5 provided with grooves 5a
extending inwardly from one end thereof into which key-like projections 16 on the core-
engaging portion 6 of the spool shaft 2 are inserted. The grooves 5a are formed only
part-way into the wall of the ribbon-winding core 5.
Kanai discloses a winding core in a ribbon cassette, the winding core 1 being
formed generally in a cylindrical shape and having an inner peripheral surface 2 formed
with a plurality of engaging grooves 7 for engagement with a plurality of engaging
projections 37 formed on the outer peripheral surface of a winding bobbin 35A. The
engaging grooves are formed such that three engaging grooves have insertion sides on
one axial end side of the winding core and three engaging grooves have insertion sides
