Abstract: 1,59,849. Self-processing cameras. INTERNATIONAL POLAROID CORPORATION. Aug. 4, 1964 [July 31, 1963(2)], No.31556/64. Heading G2A. An exposed photographic sheet is processed within the camera by passing it between pressure rollers in contact with a second sheet having a surface layer impregnated with processing liquid, the final positive image being transferred on to said second sheet. The negative sheet 44 is housed in roll form in a chamber 42 of the camera, and is drawn along the back wall 36, where an exposure is made as it passes over the exposure opening 30. The sheet then passes between pressure rollers 164, 166, and so out of the camera through a slot 114. The print-receiving sheet 84, described in more detail in Specification 1, 059, 850 is housed in a chamber 82. This chamber is lined with a sealing material which forms a seal round sheet 84 as it passes out of the chamber. The back wall 36 of the camera can open on a hinge 40, for insertion of the negative roll 44, and the end section 16 enclosing the chamber 82 can open on a hinge 86 for insertion of the container 118. The rollers 164, 166 are normally biased out of contact, and are brought into contact only during a processing operation. This is effected by rotating a crank (176) at the top of the camera, Figs. (not shown) 2 and 4, which at the same time separates the sealing edges 142, 154 of the chamber lining sufficiently to allow movement of sheet 84, and also effects the actual transport of sheets 44 and 84 between the pressure rollers and out of the camera through slot 114. They can then be cut off by severing against a sharp serrated edge provided adjacent the slot.
