    摘要： An electrographic copying apparatus and process for producing copies of graphic originals utilizing the electropowder process. The apparatus comprises a pod assembly for storing a supply of a photosensitive web material and for supporting sections thereof during imaging and development. The web material during development supported on the outer peripheral surface of the pod assembly and the developing surface is conductive to permit the electric field to be developed at the developing station. The pod preferably has a flat planar surface upon which the web is placed during imaging and a curved surface where the web is placed as the pod is moved during development. The pod is adapted for supporting two imaged sections to afford the production of two copies on each revolution of the pod.

    摘要： A copying machine in which a light-sensitive intermediate sheet and an original document are fed into intimate copying contact with the leading edge of the intermediate sheet extending beyond the leading edge of the original document. A semi-reflecting surface is positioned between a light source and a supporting surface and cooperates with the light source and the supporting surface for reflex exposure of the intermediate sheet and the original document. The semi-reflecting surface is formed to cooperate with the supporting surface to transport the original document and the intermediate sheet in intimate contact therewith between said surfaces upon relative movement between the supporting surface and the semi-reflecting surface.

    摘要翻译： 一种复印机，其中将感光中间片和原始文件与延伸超过原始文档的前缘的中间片的前缘进行紧密的复制接触。 半反射表面位于光源和支撑表面之间，并与光源和支撑表面配合，用于反射曝光中间片和原稿。 形成半反射表面以与支撑表面配合，以便在支撑表面和半反射表面之间的相对运动时，将原始文件和中间片材在所述表面之间紧密地接触。
