ABSTRACT:
A photographic processing apparatus having a plurality of processing tanks and a guide rack structure detachably mounted thereon for guiding a long strip of photographic material passing through the tanks. The guide rack structure has a pair of guide members removably installed into each of the tanks, and each pair is movable to define the width of guide passage therebetween and thus guide lengthwise edges of the long strip passing through the tank. Width adjusting mechanisms are provided, one for each pair of guide members, for adjusting the width of guide passage so that it is equal to the width of the long strip of photographic material. A drive mechanism is coupled to all the pairs of guide members to drive the width adjusting mechanisms and thus effect width adjustment. A power transmission is provided between the drive mechanism and each width adjusting means for connecting and disconnecting the transmission of drive power from the drive mechanism to the width adjusting means.
