Edge printing device

Claim 1

An edge printing device for use on a document reproducing apparatus which includes a document exposure station having a predetermined lateral dimension and means for moving the document past the exposure station, said device printing supplemental information along the edge of a copy sheet on which a document having a smaller lateral dimension than said predetermined lateral dimension has been reproduced, said device comprising: A. support means mounted on said document reproducing apparatus and extending across said document exposure station, B. an indicia roller rotatably mounted on said support means adjacent one end of said support means in a position to be beyond the longitudinal edge of a document which has a lateral dimension less than said predetermined lateral dimension, C. a friction roller rotatably mounted on said support means at an intermediate location along said support means such that said friction roller is in contact with a document as the document is moved past the exposure station of the reproducing apparatus, and D. means connecting said indicia to said friction roller for movement therewith, whereby the moving document drives said friction roller which in turn rotates said indicia roller so that the supplemental information thereon is copied simultaneously with the image on the document in an edge portion of the copy sheet which is beyond the lateral dimension of the image on the copy sheet.
