DETAILED DESCRIPTION What is claimed is: 1.
A photographic sheet film feeding device comprising: a film loading means for receiving stacked sheets of film, said film sheets being covered by an inverted U-shaped doupling plate and contained in an internally loaded bag in a light-tight condition and supporting said film sheets and said bag in an upright position, a cutter mechanism for cutting and unsealing the lower end of said internally loaded, upright bag, and a film discharging means for raising the upper end of said internally loaded bag and said U-shaped doubling plate covering the front, rear and upper edge of the upright film sheets in order to uncover the sheets of the film contained in said bag from the raised portion of said internally loaded bag.
2.
The feeding device of claim 1, further including means for locking the lower end of said upright internally loaded bag in a position for cutting the lower end of said internally loaded bag with the cutter mechanism.
3.
The feeding device of claim 1, wherein said film discharging means comprises gripping members for gripping the upper end of said upright internally loaded, bag and an upper portion of said doubling plate.
4.
The feeding device of claim 1, further including a sheet removal means comprising suction cups synchronously activatable and operatively positioned relative to said uncovered sheets of film for removing under vacuum pressure, a sheet of film from said uncovered stack of film sheets and means for releasing the vacuum pressure to discharge the sheet of film removed from said stack at a desired position.
Description:
BACKGROUND OF THE INVENTION 1.
Field of the Invention This invention relates to a photographic sheet film feeding device used, for example, for loading a photographic sheet-like film sheet by sheet into a cassette.
2.
Description of the Prior Art In conventional X-ray photographic film feeding devices, sheets of film are removed from a bag i.
e.
, an internally loaded bag, in a dark room to load them into a light-tight magazine, and the sheets of film retained in the feeding device are fed sheet by sheet from this magazine
