  • Patent number: 4365793
    Abstract: A hinged-cover holder receives a film storing magazine. A cavity with an upward opening is positioned below the magazine holder. The cavity also has an exit opening with a light-tight closure mechanism. A planar slide is between the magazine and the cavity and when it is moved from between them it opens both the magazine and the cavity in a light-tight manner so that a stack of film sheets in the magazine falls into the cavity. Transport consists of a stacking arm which pushes the film stack against a separate knife and a downward pressing arm which pushes the film stack toward a powered roller beneath the cavity, which is spaced from the separator knife by about the thickness of a film sheet. Rotation of the roller moves the lower-most film sheet between the roller and the separator knife and through the light-tight exit closure.
