ABSTRACT:
A device for rotating by a small angle, documents placed on an imaging device platen, for improved skew angle registration during imaging. An imaging device provided with a platen cover for covering the imaging platen of the imaging device includes document engagement member rotatably supported on the platen cover, between the imaging platen and the platen cover when the platen cover is in a closed position with respect to the platen of the imaging device. The document engagement member has a document contacting surface providing substantially non-slipping engagement of the document engagement member with documents placed on the platen when the platen cover is closed. An arrangement is provided for rotational adjustment of documents placed on the platen, at an externally accessible surface of the platen cover, and coupled to the document engagment member, for rotating the document engagement member through a small angle increment, and by consequence, documents engaged thereto, with respect to the platen.
