An automatic developing apparatus which can supply a photographic film without use of a leader. The automatic developing apparatus 100 has an automatic loader 31 in which a plurality of film containers 1 are held in a holder 32, a feed-out control mechanism 33 and a shutter mechanism 35 to individually and successively position the containers 11 in a film draw-out position, a film draw-out mechanism for withdrawing the film 1 in the condition that the curling of the film 1 is prevented, and a developing tank for developing the film. According to another embodiment of the invention, in the case where the container 1 is not used, after the cartridge 2 has been supplied into the film draw-out position, positioning of the cartridge 2 is performed by rotating the cartridge 2 so that the draw-out portion of the cartridge 2 is correctly oriented.

FIG. 1 is a perspective view of a film container according to an embodiment of the present invention;
FIG. 2 is a perspective view of the film container in an opened state;
FIG. 3 is a sectional view of the film container according to the invention;
A first embodiment of the present invention will be described hereunder with reference to FIGS. 1 through 6. Figs. 1 through 3 show an example of the film container according to the present invention. FIGS. 4 through 6 show the configuration of an example of the automatic developing apparatus using the film cartridge. In the following description of the embodiments, the film container and the automatic developing apparatus will be described successively.
With respect to the external appearance of the film container 11, the container is substantially shaped like a rectangular parallelepiped and includes two pivotally attached half portions which can be opened along diagonally extending line a.
A pair of guide portions 13 are respectively provided so as to extend from opposite end portions of an upper face 12 and a pair of guide portions 15, opposite to the pair of guide portions 13, are further provided in opposite end portions of a front face 14 perpendicular to the upper face 12. Additionally, a pair of guide projections 16 are provided on the upper face 12 opposite the pair of guide portions 13. As explained below, the guide projections 16 serve as guides for supplying the container 11 to the automatic developing apparatus.
