By rotating the guide presser 17 by 90 degrees, the presser foot of the upper turn guide 12 can be released.

Above the other end of the shaft 8, a guide plate 18, which is long in the direction of transport of the photosensitive material, is arranged, and the guide plate 18 is attached to the inner surface of the side plate 19 of the developing box 1. The guide plate 18 is provided with a notch 20 at a position facing the other end of each shaft 8 through which the other end of the shaft 8 can pass, and a plurality of guide holes 21. , consisting of a long hole extending in the direction of transport of the photographic material.

A stopper plate 22 that presses the other end of the shaft 8 is superimposed on the lower surface of the guide plate 18.
A pin 23 that is inserted into the guide hole 21 is attached to the stopper plate 22. Therefore, the stopper plate 22 is movable within the range where the pin 23 comes into contact with both ends of the guide hole 21, and the spring 24 connected to one end of the stopper plate 22 allows the pin 23 to come into contact with one end of the guide hole 21. The stopper plate 22 is deflected in this direction.

As shown in FIGS. 4 and 5, the stopper plate 22 is provided with a notch 25 that matches the notch 20 of the guide plate 18 when the pin 23 is in contact with one end of the guide hole 21. There is.
