Abstract

The photographic copying frame has a glass window (1) which comes into contact with the metal sheet (2). The edge of the glass frame has a soft rubber frame (5) to form a seal. The plate is located by the perpendicular clips (4). The film is kept in contact with the frame by evacuating the space between the glass and the metal. The frame is supported on a base plate (3) which has four corner legs.
