Abstract: A system for imprinting stationery including envelopes, letters and cards with return addresses, sending addresses, letterheads and other indicia uses inexpensive self inking stamps. A horizontal rectangular top plate is provided with apertures through which the stamps pass when imprinting on a piece of stationery. The top plate is supported above a flat horizontal support surface on which the piece of stationery rests by a three sided fence which provides positioning stops for the stationery. The apertures are located at predetermined positions on the top plate so as to correctly position imprinting of sending addresses, return addresses and letterheads on stationery of various sizes. The positioning and registry is so well maintained that different colored stamps may be used in the same aperture to produce multicolor printing. By providing a system that produces high quality custom printed stationery as needed, the volume storage and expenses of preprinted stationery is avoided.

Abstract: A thermal-transcription printer has a printing head and a platen drum which is moved up and down to press thermally activated ink from a thermal transfer ribbon onto a paper. A lever member is installed on a feed roller for transferring a paper sheet, and the platen drum is supported by an end portion of the lever member. The platen drum moves up and down, while being supported by the lever member which rotates in the same direction as the feed roller, and presses an ink ribbon and the paper against the printing head.

Abstract: The beveled ends of a flexible printing plate are clamped in a cylinder slot by a plurality of spring teeth that are receivable cutouts in the plate beveled ends. The spring teeth are part of a comb plate that is supported by a rotatable clamping lever. These teeth will also function as plate end ejectors when the clamping spindle is rotated in a plate end ejecting direction.

Abstract: A device for fastening a rubber blanket unit to a blanket cylinder utilizes a rubber blanket secured to the surface of a support plate which is provided with beveled ends. These ends are insertable into a narrow slit in the cylinder and are held in the slit by pressure elements. The beveled support plate end lateral surfaces are in contact with each other.
