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. A level sensor is installed in each of the solution tanks which monitors the level of the processing solution in the respective solution tanks. A plurality of shield members are provided, each shield member surrounding and protecting a respective one of the level sensors, and each shield member being detachably mounted to its respective level sensor. Each of the shield members includes a plurality of split members which are separable from each other and which are connectable to each other to surround the respective level sensor.
