Self Registering Document Feed for Copier

Canted wheels drive a document across a document glass and against registration edge.

In a copier, documents entering a document glass out of alignment, for example, position A, must be aligned in a standard position B, in registry with copier gates (not shown). Canted drive wheels press against the glass and rotate on shafts turned by a drive motor. The center of each wheel falls on a center line parallel to the registration edge.

Misaligned incoming documents are driven by the canted wheels against the registration edge and across the glass into registry with the gates. The canted wheel angle (Phi) falls between 2 Degrees and 20 Degrees nominal direction of paper travel. Typical wheel materials are rubber, silicone and urethane foam.
