ABSTRACT:
A rack of a film feed unit for an automatic film developing machine is formed by two rack plates, one of which is formed in its side plates with cutouts. Film feed members can be easily mounted on the rack plate by inserting its ends into the cutouts from the front of the side plates. Also, each rack plate may be divided into a plurality of blocks, each having one end formed with grooves and the other end with projections to be engaged in the grooves to combine the blocks together. Thus, by changing the number of blocks to be coupled together, the length of the rack can be adjusted to the depth of a treating tank in which it is to be hung. Also provided in the rack are members for preventing films from meandering while being fed to the rack.
