the incoming mail speed. Rather, real events and activities
occur in response to the detecting of the incoming mail speed.
The incoming speed of an envelope is characteristic of
the incoming envelope, given the appellants’ disclosure in
their own specification (page 3, line 38 to page 4, line 7)
that the motor drive current of sheet feeder 20 is the
preferred source of characteristic signals of the incoming
sheets. Motor drive currents reflect the speed of the feeder
20. Accordingly, Chang does disclose the production of a
signal characteristic of the incoming sheets.
Finally, the appellants argue that while the claimed
invention slows down the sheet processing speed if the sheet
is likely to jam in the apparatus, Chang slows down the
processing speed after a jam has already occurred, citing
column 6, lines 11-17, of Chang. However, a reasonable
reading of Chang reveals that the cited portion describes only
a further feature for handling the occurrence of a jam and not
the ordinary operations of the mailing machine.
