发明名称 Integral film assemblage of the instant or self-developing type
摘要 A self-developing integral film assemblage or unit adapted to be advanced between a pair of liquid spreading members in a camera to distribute a processing composition between a first positive or image-receiving sheet and a second negative or image-recording sheet. The composition is supplied from a pod which is located at a leading end of the film unit and excess thereof is absorbed by a trap at a trailing end of the unit. The first and second sheets are properly spaced by an intermediate masking sheet of uniform thickness which has an image-defining aperture therein. This mask assures that a uniform thickness of the processing composition is spread between the first and second sheets. The mask may also include a cutout adjacent to and outside of the image area defined by the aperture so as to enable an underlying portion of the second sheet to be photographically exposed to indicia relating to the exposure.
