Electric motor driven imprinter apparatus for imprinting characters from a character imprint source member onto document sheets or the like, including a housing having a driven roller moved back and forth transversely across an imprint station, a horizontally slidable carrier block member and a changeable cassette carried by the block member having a changeable vertically slidable roller block member and a roller rotatably carried thereby. 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.

An electric motor driven imprinter (60) in accordance with the invention includes a base (70) for receiving a print bearing element (62) having printing to be imprinted on a print receiving element (64) with the electric motor being mounted in the base; a head (61) pivotally connected to the base for imprinting; a movable carriage (116) mounted on the head having mounted therein a rolling platen (128) driven by the electric motor (82) to move the carriage in a first direction and a second opposite direction along a longitudinal axis with movement in each direction to one of a pair of ends of travel (110, 112) imprinting print from the print bearing element on the print receiving element; a capstan (84) which is driven by the motor; and a cable (86) attached to the capstan, forming a loop between the capstan and an idler wheel (142) attached to the head at a point along a longitudinal axis of the head adjacent an end of travel spaced farthest from the capstan and attached to the movable carriage.
