Abstract
Apparatus for the exposure and development of photographic images in a photographic monosheet material having two frame members. The first frame member holds the monosheet with the photosensitive side sealed against light and moisture and the opposite side facing an opening. The second frame member is hinged on the first member. Means are provided for sealing the second member in a closed position on said first member and means are provided for applying a processing liquid to the monosheet material while the frame members are closed together.
Claims11
In an apparatus for development of photographic images the combination comprising,
- a frame means adapted to hold a laminated monosheet material having a first member defining an opening and provided with a lateral surface extending inwardly from the frame into the opening, and forming a shoulder
- for receiving a photosensitive side of said monosheet material,
- a seal means seated over the monosheet material,
- a second frame member hinged to one side of the first frame member and defining an opening substantially coextensive with the opening defined by said first frame member,
- means for lockably attaching the first and second frame members together
- whereby the seal means and the monosheet material are pressed against the shoulder in the first frame in a light proof and moisture tight manner when said second member is locked to said first frame member, and
- means associated with said first frame member and located on the side of said first frame member most adjacent to the photosensitive layer of said monosheet material
- and being able to protect said photosensitive layer against light.
In an apparatus for development of photographic images the combination comprising,
- a laminated monosheet material comprised of
- a layer impermeable to light and a photosensitive layer,
- a frame means for holding said monosheet material having a first frame member defining an opening and provided with a lateral surface extending inwardly from the frame member into the opening and forming a shoulder,
- said shoulder receiving the photosensitive side of said monosheet material,
- a seal means seated over the monosheet material,
- a second frame member hinged to one side of the first frame member and defining an opening substantially coextensive with the opening defined by said first frame member
- means for lockably attaching the first and second frame members together
- whereby the seal means and the monosheet material are pressed against the shoulder in the first frame member in a light proof and moisture tight manner when said second frame member is locked to said first frame member, and,
- means associated with said first frame member and located on the side of said first frame member most adjacent to the photosensitive layer of said nonosheet material and being able to protect said photosensitive layer against light.
Apparatus for the development of photographic images using dye diffusion processing, including
- a developing container adapted to hold a laminated monosheet and a substantially rectangular shaped lower part provided to receive an image-wise exposed monosheet and
- a lid hinged to one longitudinal side of said lower part and
- means for lockably attaching the lid to the lower part, and
- a rubber or plastic sealing body provided on the side of the lid facing the lower part and positioned so that the sealing body and monosheet engage all round so that the edges of the monosheet are locked, with the lid, in a light-proof and moisture-tight manner against the bottom of the lower part, and the lid is provided with an inlet nozzle and an outlet nozzle.
