A film processing apparatus having a row of film developing tanks and a plurality of wires positioned above the tanks. The wires slidingly support a carriage over the row of developing tanks and also function as conductors to switches associated with the carriage. These switches control a motor for stopping the carriage over a successive tank and for reversing the motor to lower the film to be developed into the tank. The starting of the motor is controlled by a tape recorder that plays back tape on which audio-frequency signals of predetermined durations at predetermined intervals have been recorded.
