    Abstract: A self-developing camera for use with a photographic film unit including a photosensitive sheet and a second sheet secured in face-to-face relation by external binding strips secured to the lateral margins of the sheets and adapted to be processed to produce a visible image by a liquid processing agent distributed between the sheets in a uniform thin layer at least coextensive with the exposed area of the photosensitive sheet. The camera includes a pair of juxtaposed pressure-applying rolls for distributing the processing liquid between the sheets, and one of the rolls includes annular grooves near its ends for receiving lateral edge portions of the binding strips during movement of the film unit between the rolls to relieve the pressure on the edge portions of the binding strips while the medial sections of the rolls engage the sheets and are spaced apart by engagement of the end sections of the rolls with the binding strips at the lateral edges of the film unit.

    Abstract translation: 一种用于与照相胶片单元一起使用的自显影照相机，其包括感光片和通过固定到片材的侧边缘的外部装订条而以面对面关系固定的第二片，并且适于被处理以产生可见图像 通过分散在片材之间的液体处理剂以至少与感光片的曝光区域共同延伸的均匀薄层。 相机包括一对并置的压力施加辊，用于在片材之间分配处理液体，并且一个辊子在其端部附近包括环形槽，用于在膜单元在辊之间移动期间接收装订带的侧边缘部分 减轻了装订带的边缘部分的压力，而辊的中间部分与片材接合并且通过辊的端部部分与胶片装置的侧边缘处的装订条的接合来分隔开。

    Abstract: A photographic film unit comprising all of the materials required to produce a photographic print including a photosensitive element, a transparent image-receiving element, a container of processing liquid and a binding element secured to the exterior margins of the photosensitive and image-receiving elements adjacent three sides of the area to be exposed and processed. The binding element secures the photosensitive and image-receiving elements to one another along three sides of the exposure area and secures the container to the elements adjacent the remaining side of the exposure area. The film unit is designed to be maintained in tact throughout and subsequent to exposure and processing in which a processing liquid is discharged from the container and distributed in a layer between the photosensitive and image-receiving elements over the exposed area to form a transfer image between the elements. The external binding sheet functions to control the thickness of the layer of liquid insuring sufficient liquid at the edges of the exposed area to provide for complete image formation and providing a white border for the finished print. The image-receiving element is embossed at the borders of the image-receiving area.
