<p>Operating device to rotate the film supports (13,14) for a developer of photographic material, which comprises a plurality of tanks (5,6) containing the liquid chemical agents and which are provided with a circuit having a pump (7) for the reagent circulation. According to the invention, the device comprised a relative rotor (15) associated with the supports (13,14) and a nozzle (16), disposed in front of the rotor (15) and installed at the end portion of the return pipe (9) of the circulation circuit of the reagents, which pipe is connected to the tank. In this manner, the fluid jet of the reagents coming from the nozzle (16) and regulated by a valve (17) may rotate the supports (13,14) and also the photographic material without use of the conventional mechanical devices for driving said supports (13,14).</p> |
