ABSTRACT:
A pressure roller assembly for use in a camera of the type adapted to expose and process self developing film units includes a pair of rollers held in juxtaposed relation within a frame having open ended slots for receiving the ends of the rollers. Unimpeded radial displacement of the rollers away from each other is limited by a pair of bearing blocks blocking the open ends of the roller receiving slots. The bearing blocks are urged toward the rollers by a bow shaped spring having arms adapted to engage the frame to hold the spring under tension against the bearing blocks. The ends of the bow shaped spring bear against the bearing blocks at a point contact.
