Appeal No. 96-3746
Application 08/236,007
Claim 1 is illustrative of the subject matter on appeal and
recites:
1. An ink supply control device for a stencil printing
machine which controls the supply of printing ink to an ink
reservoir formed in a printing drum according to a signal
produced from an ink amount detecting device which produces a
first signal when the amount of ink stored in said ink reservoir
is detected to be greater than a prescribed level, and a second
signal when the amount of ink stored in said ink reservoir is
detected to be less than said prescribed level, comprising:
an arithmetic computing device for computing a relative
relationship between a time period during which said ink amount
detecting device produces said first signal and a time period
during which said ink amount detecting device produces said
second signal;
an ink amount determining device for determining if the
amount of ink in said ink reservoir is less than said prescribed
level or not according to a result of said computing by said
arithmetic computing device; and
an ink supply device for supplying printing ink to said
ink reservoir when an output from said ink amount determining
device indicates that the amount of ink in said ink reservoir is
less than said prescribed level.
