Abstract: A hinge link connecting a cover to an office copier machine is completely enclosed by the cover when the cover is swung down in a closed position on the copier machine. One edge of the hinge link is connected to the top of the copier machine by a first pivotal joint and an opposed edge of the hinge link is connected to the cover by a second pivotal joint. The two pivotal joints permit the cover to be swung open around the first pivotal joint and enable the cover to be disposed substantially parallel to the copier top to accommodate articles of varying thickness placed between a platen on the top of the copier and the cover. The hinge link may be planar or it may be angular. In the latter case, the short leg of the angle is substantially the height of the cover with the other leg having a length greater than the short leg to permit the hinge link to be totally enclosed within the chamber of the cover and to enable the cover to be disposed spaced from the copier top.

Abstract: A removable cartridge like toning device for electrophotographic imaging apparatus of the type wherein a latent electrostatic image formed on an endless electrophotographic belt is translated past a toning station for rendering the latent image visible. The toning device described is a box-like container for liquid toner having an elongate longitudinal slot formed in the top wall and a feed roller seated for rotation within said container, a portion of the circumferential outer surface of the roller extending from the slot. The side walls of the container are provided with inclined flanges cooperating with conformingly inclined ramps provided in the imaging apparatus at the toning station so that the container is guided to a position closely spaced substantially parallel to the electrophotographic belt.
