Abstract: A film bonding apparatus in which a film cut to a length corresponding to that of a base plate is bonded to the surface of the plate by the application of heat and pressure with a bonding roller. The film is provided from a continuous roll and is cut to appropriate size, the trailing edge of the film being held tightly to avoid film wrinkling or air bubbles by the suction action of an edge holding member whose effective length is not less than the maximum width of the films to be bonded by the apparatus. The holding member is moveable, at a speed equal to or slightly less than the rotative circumferential velocity of the pressure roller, the speed being automatically adjusted to maintain appropriate tension on the film. Coordinated movement between the film holding member and the pressure roller is provided by a gear mechanism.

Abstract: A developing unit comprising a developing chamber having an upper film pass roller and a lower film pass roller, a gasifying chamber, and a heating chamber, discharging outlets connecting from the heating chamber to the developing chamber at upper and lower portions of the upper film pass roller, and sucking inlets connecting from the developing chamber to the gasifying chamber at upper and lower portions of the lower film pass roller, so that the surface area of each sucking inlet is made substantially equal to that of each discharging outlet. This improves convection efficiency of the hot blast and thus temperature differences between the upper and lower portions within the developing chamber thereby preventing tone variations of the copied images.

Abstract: A thermal printer wherein a sheet of recording paper is interposed between two drums provided on axially opposite sides of a shaft of a platen roll facing a line-type thermal head and an endless belt mounted on outer peripheries of the drum. One way clutches provided on a shaft of the drum will cause the paper to rotate together with the drums during recording and the recording paper is driven by the endless belt during paper feed and delivery operations to slide relative to the drums. The sheet of paper is fed to a lower portion of an open portion of the drums and is removed from an upper portion of the open portion of the drums so that the feed and delivery of the sheet of paper can be effected upon rotation of the drums in one direction, and the printing operation is started after a detection of a trailing end of the sheet of paper so that the printing operation can be reformed regardless of the length of the sheet of paper immediately after the feed of the sheet of paper.

Abstract: A paper tension adjusting device in which one of the tractors with feeding pins changing feeding apertures in the paper is movable widthwise to adjust widthwise paper tension. The desired tension is determined from paper thickness which is in turn determined from the hammer flight time. Lengthwise tension is adjusted by adjusting paper clampers separated from the tractors. The tension is both widthwise and lengthwise directions is determined by optically sensing the positions of the feeding pin with respect to the aperture in which that pin is engaged.
