Abstract
A direct control paddle wheel apparatus for document corner registration includes a paddle wheel with multiple blades that drive a document into registration with intersecting walls. The blades, as they rotate, are channeled in a direction plate or in the alternative along the surface of an interference barrier and, as a consequence, drive a document from side to side, as well as straight ahead depending on the shape of the plate or barrier.
Claims9
An apparatus for controlling the direction of movement of substrates comprising:
- paddle wheel means for driving a substrate, said paddle wheel means having at least one blade attached thereto and in driving relationship with a substrate;
- force producing means for rotating said paddle wheel means and thereby moving said blade in a first direction of travel to drive the substrate therewith;
- direction control means located in the path of said first direction of travel such that at a point of rotation of said paddle wheel means said blade is deflected from said first direction of travel into a second direction of travel, whereby substrates being driven in said first direction of travel are driven in said second direction of travel.
In a copier having a platen for exposing documents thereon, the improvement of a direct control paddle wheel document registration system, comprising:
- corner means formed adjacent an area of said platen, said corner means including intersecting registration walls;
- paddle wheel means adapted for driving a document on said platen in a first direction, said paddle wheel means having multiple blades attached thereto;
- force producing means for rotating said paddle wheel means and thereby moving said blades in said direction of travel;
- and
- direction control means located within said first direction of travel such that at a point of movement of said paddle wheel said blades are deflected from said first direction of travel into a second direction of travel, whereby the document driven in said first direction by said paddle wheel is driven in said second direction of travel once said blades are deflected, said second direction of travel being arranged to deflect the document in said corner means in corner registration therewith.
