Appeal No. 95-3720
Application 08/088,146
This is a decision on the appeal under 35 U.S.C. § 134
from the examiner's rejection of claims 1-11, 14 and 15. Claims
12 and 13 have been allowed by the examiner.
The invention pertains to an apparatus for cleaning
debris from a movable photoreceptor belt of an electronic
reprographic image forming apparatus. More particularly, a
cleaning roller and a pressure roller are placed to define a nip
through which the photoreceptor belt moves. A means is provided
to maintain a substantially uniformly distributed contact
pressure between the cleaning roller and the photoreceptor belt.
Representative claim 1 is reproduced as follows:
1. An apparatus for cleaning debris from a movable
photoreceptor belt having an outer surface and an inner surface,
comprising:
a rotatably mounted cleaning roller adapted to remove
debris adhering to the outer surface of the photoreceptor belt;
a rotatably mounted pressure roller mounted adjacent to
the inner surface of the photoreceptor belt, said cleaning roller
and said pressure roller defining a nip through which the
photoreceptor belt moves; and
means for continuously maintaining a substantially
uniformly distributed contact pressure between said cleaning
roller and the outer surface of the photoreceptor belt.
