Abstract
Abstract A processing apparatus having two chambers, one for properly processing a film of one type or ASA number, and the other for properly processing a film of a different ASA number or type. Each of the processing chambers is provided with a film supporting rack movable between an enabled position, in which the rack transports film, and a disabled position in which the film is not transported. Each chamber further has processing solution circulation, replenishment and temperature control systems. The film racks in the two processing chambers are coupled together such that movement of a rack in any one processing chamber to its enabled position results in movement of the rack in the other processing chamber to its disabled position. Once the threaded rack is moved to its enabled position and the processing apparatus threaded through all of its stations for properly processing a film of a predetermined type, an interlock system is actuated for (1) accepting for introduction into the processing apparatus only film of the predetermined type and rejecting all other types of film, and (2) activating recirculation, temperature control and replenishment systems for only the processing solution being used.
