to a frequency characteristic of the transducer. Thus, appellant
argues that there is no suggestion in either reference of an
accumulation time control means for controlling a time for
accumulating an amount of light at the change unit according to a
saturation characteristic and a frequency characteristic of the
transducer unit [brief, pages 16-18].
The examiner responds by restating the findings of the
rejection that Ishida teaches the idea of basing a light control
on the frequency characteristics of the transducer [answer, pages
11-13].
We will not sustain the examiner’s rejection of claims 8-
14 and 23, which form the second group of claims, for essentially
the reasons argued by appellant in the brief. We agree with
appellant that Ishida provides no teaching or suggestion that the
frequency characteristics of a transducer should be used in
controlling an illumination means for directing light toward an
original document for reasons discussed above.
We now consider the rejection of claims 20, 21 and 24
based on the teachings of Arimoto and Pelton. These claims stand
or fall together in two different groups which are respectively
headed by independent claims 20 and 21 [brief, page 6]. With
