Abstract

A document feeder for a reproducing machine is proposed which eliminates the need for a registration gate for registering a document 2 on a viewing platen 3. The document 3 is pre-registered against a pivoting stop 4. It is then fed in a timed relationship onto the platen, A segmented friction drive system 5 is used to insure that the document is driven a given distance after pre-registration so that it is properly registered on the platen. The segmented drive system 5 comprises two friction rolls 6 and 7 which are operative to drive the document feeder belt 8 and input rolls 9. One of the friction rolls 6 includes a slot 10 and will drivingly engage the other of the friction rolls 7 except in the region of the slot, By controlling the operative circum-ference of the friction drive roll 6, it is possible to define the amount of travel of the document onto the platen and, therefore, maintain its registration thereon,

A document feeder for a reproducing machine is proposed which
eliminates the need for a registration gate for registering a
document 2 on a viewing platen 3.

The document 3 is pre-~registered against a pivoting stop 4.
It is then fed in a timed relationship onto the platen, A
segmented friction drive system 5 is used to insure that the
document is driven a given distance after pre~registration so
that it is properly registered on the platen. The segmented
drive system 5 comprises two friction rolls 6 and 7 which are
operative to drive the document feeder belt 8 and input rolls
9. One of the friction rolls 6 includes a slot 10 and will
drivingly engage the other of the friction rolls 7 except in
the region of the slot, By controlling the operative circum~
ference of the friction drive roll 6, it is possible to define
the amount of travel of the document onto the platen and,
therefore, maintain its registration thereon,
