Appeal No. 95-2911
Application 07/814,693
metal to obtain Appellant’s invention as recited in claim 5.
The Examiner further states on pages 4 and 5 of the answer that
[i]t was well known in the art to make use of this
advantage [the advantage of sheet metal to be stamped
into desired shapes] to form structures (which are not
expected or designed to undergo movement relative to
each other) as a unitary body so as to simplify the
assembly thereof and to better ensure that such
structures do not move relative to each other.
Upon a careful review of Maeda and Kato, we find that
neither reference teaches
a carriage formed of sheet metal for carrying the
magnetic head; . . . in which the sheet metal forming
the carriage includes a narrow bracket portion
extending therefrom and having an integrally formed,
upraised, wedge-shaped element having flat sides
tapering to a thin edge for engagement with a thread
groove of a feed screw and being formed of press-worked
sheet metal, the sheet-metal being the same sheet-metal
forming the carriage so as to form a unitary structure
as recited in Appellant’s claim 5. In Figure 1, Maeda shows the
carriage 10 and a part separate from the carriage, a needle 22
for engagement with a thread groove 21 of the feed screw. In
addition, the Examiner agrees that Maeda does not meet the above
limitations recited in Appellant’s claim 5. In particular, the
Examiner states on page 3 of the answer that Maeda does not teach
“the carriage and the engagement piece being formed as a unitary
body from the same sheet metal.”
Kato teaches in Figure 7 a carriage 38 and a part separate
from the carriage, a needle 39c for engagement with a thread
