ABSTRACT:
An automatic photographic developing apparatus for photosensitive materials includes a number of processing baths which are filled with processing solutions of different types for processing silver halide coated photosensitive materials. A same number of solution tanks communicated with the respective processing baths are provided for supplying the processing solutions, produced by dissolving solid agents, to the respective processing baths. Each of the solution tanks is protected with an openable cover and is provided with a guide along which the respective solid agents can be loaded into the respective solution tanks for dissolution as the solid agents run down by their own weight. The guide is pivotably mounted for movement between a guiding position and a non-guiding position and is urged by a return spring so that the guide can automatically return to the guiding position.
