Abstract: The invention is directed to a device for obtaining accurate registration of handwritten impressions on continuous business form sets which are detachable into individual form sets by means of longitudinally spaced transverse perforations. The device includes a pocket for receiving the continuous business form sets folded in a zig-zag manner and has a registration plate defining a writing surface for the individual business form set upon which a handwritten entry is made. The outer edge of the registration plate coacts with the transverse perforation to ensure accurate registration of the original sheet and copy sheets of an individual business form set upon which a handwritten entry is made.
