A pair of spaced apart rotatable sprockets and an endless drive chain having a spud projecting therefrom and provided for driving the carrier block member and roller block member back and forth through advance and return strokes spanning the imprint station. The roller block support structure is movable from an imprint position to a release position for removable and replacement of the roller block member and roller, and a carrier member is hinged for pivotal movement relative to the casing and has a recess for receiving the imprint source member and a pocket for document sheets.
