device. We also note that control unit 27 together with
operation unit 28 provide various control signals as well as the
recording/reproducing speed based on both the stored commands or
manual entries by an operator (col. 6, lines 21-23 and col. 9,
lines 25-27). We also remain unpersuaded by Appellants’ argument
that a control means separate and apart from the input/output
control means is absent from the single control unit of Nagasawa
since we do not find such limitation (separate control means)
required in the claimed invention. In fact, the control unit of
Nagasawa performs the function of controlling the recording and
reproduction of video data reproduced from multiple and different
sources (col. 5, lines 13-15). Additionally, control unit 27
determines the speed of data transfer by probing the format and
the speed of the data inputted/outputted through input/output
interface circuits 23 and 24 (col. 4, lines 36-39) or the data
transfer speed designated by control unit 27 (col. 7, lines 11-12
and col. 9, lines 25-27).
With respect to Appellants’ argument that Nagasawa’s control
means does not “inquire about reproduction speed” to the
“input/output controlling means,” we find Examiner’s reliance on
the disclosed speed designation commands in columns 5, 7 and 9 to
be persuasive. Of particular relevance to the claimed
