摘要： Photographic apparatus including film-advancing fluid processing means for use with a self-developing photographic film unit including a first image-recording sheet element secured in superposed face to face relation with a second image-receiving sheet element by external binding means secured to and overlapping the longitudinal and lateral edges of the sheet elements and defining, in part, an exposure area of the film unit, the film unit adapted to be processed to produce a visible image as a processing fluid is distributed between the sheet elements, coextensive with the exposure area, in a layer with a predetermined cross-sectional configuration. The film-advancing fluid processing means includes a pair of rotatably mounted juxtaposed pressure applying rollers resiliently urged toward one another and adapted to spread the processing fluid between the sheet elements of the film unit as it is advanced between the rollers. At least one of the rollers is a structure including a generally rigid support member with a pair of spaced apart annular grooves therein, a layer of high-friction resilient material overlying the support member and having an internal configuration similar to that of the support member and an external configuration that is a substantially cylindrical sheetcontacting surface being relatively more deformable in those portions overlying the annular grooves of the support member whereby the binding means on the surface of the second sheet element along the longitudinal edges of the film unit, when disposed within these deformable portions, are permitted to move toward the annular grooves of the support member during spreading of the processing fluid between the sheet elements.

摘要： Apparatus including a pair of rollers for spreading a processing fluid between a pair of photographic sheet elements at least one of which forms part of a film unit of the self-developing type. One of the rollers is rigid, having a substantially cylindrical configuration. The other roller is structurally configured to include a rigid support member having a curved exterior surface of convex shape over which lies a layer of resilient material having an internal shape similar to that of the exterior shape of the support member and an exterior sheet contacting surface whose shape is substantially cylindrical. Because of the structure of this second roller, the thickness of the resilient layer varies across the length of the roller thereby permitting a variation in the deformation capability of its sheet contacting surface. By specially selecting the variable deformation characteristics of this surface, both the initial distribution and subsequent flow patterns of the processing fluid may be controlled to meet the design requirements that the fluid thickness between the sheets be uniform and the film unit size minimized.
摘要翻译：一种装置，包括一对辊，用于在一对照相片元件之间铺展处理流体，其中至少一个照相片元件形成自显影类型的胶片单元的一部分。辊中的一个是刚性的，具有基本上圆柱形的构造。另一个辊在结构上被构造成包括刚性支撑构件，该刚性支撑构件具有弯曲的凸形外表面，所述刚性支撑构件具有与支撑构件的外部形状类似的内部形状的弹性材料层和外部片接触表面，形状基本上是圆柱形。由于该第二辊的结构，弹性层的厚度在辊的长度上变化，从而允许其片接触表面的变形能力发生变化。通过特别选择该表面的可变变形特性，可以控制处理流体的初始分布和随后的流动模式，以满足板之间的流体厚度均匀且膜单元尺寸最小化的设计要求。

摘要： A camera of the self-developing type including an enclosure or chamber coupled to the camera for movement between a compact, inoperative position wherein at least a portion of the chamber is located against a wall of the camera and an extended, operative position in which it forms an extension of the camera and is adapted to receive an exposed film unit as it exits from the camera. The camera includes a pair of rolls for advancing an exposed film unit into the chamber. A switch is located between a source of power and the rolls and is adapted to be closed by movement of the chamber into the extended, operative position thereby insuring that the chamber is in position to receive the exposed film unit prior to the exposed film unit being moved out of the camera.
