1,039,214. Photographic cameras. INTERNATIONAL POLAROID CORPORATION. April 9, 1965, No. 15214/65. Heading G2A. In a photographic camera for exposing and processing photographic film 30, non-viscous processing liquid is stored in a reservoir 44 which is traversed across the film 30 after an exposure has been effected, the liquid being extruded on to the film through the capillary formed between walls 50, 54. When the reservoir reaches the dotted line position, it is wound back and the exposed film is HE simultaneously wound out of the camera between rollers 34, 36 where it is pressed into contact with an image receiving sheet 38. The reservoir is bounded by a flexible air and water impervious membrane which maintains the liquid at ambient pressure, the capillary being closed by a member 62 when processing is not taking place. In another embodiment, the liquid applicator may be held stationary and the image recording sheet moved so as to moisten it during withdrawal.
