detection signal from the temperatures sensor” (Brief, page 5),
the feature of temperature dependent control of a platen roller
is clearly taught by Pfeuffer. Further, although Appellants
argue (id., at 5 and 6) that Pfeuffer heats a fuser roller and
therefore fails to teach the heating of a thermal head which in
conjunction with a platen roller transfers a sheet, this teaching
is specifically provided by Fukumoto.
We further find to be unpersuasive Appellants’ assertion
(Brief, page 7) that, even if combined, the resultant structure
would not satisfy the claimed requirements. In Appellants’ view,
if the temperature sensor of the heat source in Pfeuffer, i.e.,
the fuser roller, were combined with Fukumoto the result would be
that the temperature sensor would detect the temperature of the
thermal head, not the platen roller as claimed. It is apparent
to us, however, from the line of reasoning expressed in the
Answer that the Examiner is not suggesting the bodily
incorporation of Pfeuffer’s temperature based speed controller
into the system of Fukumoto. Rather, it is the disclosed
technique in Pfeuffer of providing for constant speed control of
a sheet transfer roller in dependence upon detected temperature
