<p>Photographic film developing apparatus comprises a sequence of adjacent, horizontally aligned chambers communicating with each other at their top and bottom portions. Each is adapted to contain a selected film-treating fluid agent. An infeed port communicates with one terminal chamber of the sequence and a discharge port with the other. Magnetic carriages mounting releasable film grips are dimensioned to traverse the chambers trailing the film behind them. The carriages are actuated by a magnetic element mounted for reciprocation adjacent the chambers and associated with a reciprocating drive. Reciprocation of the magnetic element in a vertical plane drives the carriages and the film through one chamber after the other, thereby exposing the film sequentially to the action of the treating agents contained in the respective chambers.</p> |
