Appeal No. 95-1655
Application 07/788,829
We reverse this rejection.
Appellant’s prior art Fig. 3 and its associated discussion
at specification page 3 indicates that the prior art
controller/driver 16 may be operated with either 4-bit or 8-bit
microprocessors. Fig. 3 itself shows an 8-bit microprocessor
operated in an 8-bit mode with one of these prior art
controller/drivers.
On the other hand, prior art Fig. 4 also shows an 8-bit
microprocessor used in an 8-bit mode for two of the above
identified prior art controller/drivers each of which in turn is
operated in an 8-bit mode.
To meet the above noted feature of representative
independent claim 1 and the other independent claims having
comparable features, we need a teaching which indicates that an
8-bit microprocessor as claimed may operate to provide outputs
from two 4-bit modes. We do not derive such a teaching from
Nishida, which contains no teaching or suggestion of utilizing a
microprocessor in any manner. In contrast to a normal digital
data operated system, analog data feeds the ADC 2 in Nishida’s
Fig. 2 providing 8 output bits feeding in parallel to decoder-
drivers 5 and 6 respectively as well as a single decoder-driving
circuit 4. This latter driver feeds a thermal print head and the
