ABSTRACT:
A photograph developing apparatus includes a main processing tank and a sub-tank which is connected to the main processing tank. The sub-tank is provided with a filter, a sensor, and the like in order to filter processing solution and feed the filtered processing solution back to the main processing tank. The sub-tank has a lid for covering the top of the sub-tank. The lid has an evaporation prevention block which is extended to a point below the surface of the processing solution. Cavity portions are formed in the evaporation prevention block at least at positions corresponding to the filter and the sensor. Alternatively, evaporation of the processing solution is suppressed through employment of an evaporation prevention block which floats on the surface of the processing solution. In this case as well, cavity portions are formed in the block at least at positions corresponding to the filter and the sensor.
