ABSTRACT:
A single bath-type film developing device includes a developing tank, a developing and fixing liquid tank and a rinsing water tank, at least the latter two tanks being pivotable about an axis spaced therefrom for respectively altering the level of liquid and water therein relative to the developing tank. Conduits respectively interconnect the developing tank with the liquid and water tanks so that the developing tank is filled with the liquid when the liquid level is above the developing tank, and the developing liquid may be emptied back into the liquid tank and thereafter filled with rinsing water when the water level is above the developing tank. In accordance with another embodiment, the developing and liquid tanks are mounted on one surface of a pivotable support base, while the rinsing water tank and a storage tank are mounted on an opposite surface thereof. Conduits interconnect pairs of these tanks, and the developing tank is filled with developing liquid when it is uppermost. It may be emptied into the storage tank when still uppermost and, when the rinsing tank us uppermost, the developing tank may be filled with rinsing water and the storage tank may be emptied back into the developing liquid tank.
