The opening of the developing tank 70 is closed by a lid 72, and a developing solution 74 is stored inside. The transport path 76 is formed in a U-shape as shown by the alternate long and short dash line in the figure, and the film 80 is formed along the transport path along the passage path 78 at the entrance of the two passage openings formed in the lid 72.

た。However, in the above-mentioned conventional photosensitive material processing apparatus, since the lid 72 is provided with the two passage openings 78 of a size that allows the film 80 to come in and out, the passage of these two passages is performed. There is a drawback that the area where the liquid surface of the developing solution comes into contact with air through the port 78 becomes large. That is, when the ratio of the area where the liquid surface is exposed to the air with respect to the total volume of the developing solution (liquid surface opening ratio) is large, the oxidation of the developing solution is likely to proceed and the developing solution is short. There is a problem that the processing capacity deteriorates due to deterioration over time.

搬送路の長さの短縮化が望まれていた。In the conventional photosensitive material processing apparatus, the film 80 is conveyed along the conveying path 76 in one direction shown by an arrow A in FIG. Becomes longer, the apparatus becomes larger in the transport direction of the film 80, in the left-right direction in the figure, and the number of rollers required for transport increases, resulting in an increase in manufacturing cost.
It has been desired to shorten the length of the transport path.

処理が行われる。With the above structure, first, the photosensitive material is conveyed into the processing tank through the minimum passage opening through which the photosensitive material can pass, and advances. When the photosensitive material reaches the transport position where it should be retracted, the detecting means detects the photosensitive material and outputs an output signal. Based on this output signal, the control means drives the advancing / retreating means to move the photosensitive material from the advancing to the retracting at an appropriate speed, and is conveyed from the inside of the processing tank to the outside of the processing tank through the same passage opening again. The photosensitive material conveyed to the outside of the tank is guided to the downstream side which is the next step by the guide member. As described above, the entire length of the photosensitive material is immersed in the process in the process of advancing and retracting in the processing tank.

The film 16 is inserted from the film insertion opening 14, and the inserted film 16 is conveyed along the conveying path 18 and the front end portion 16
It is conveyed from A toward the downstream side (direction of arrow B).

8 enters the developer tank transport path 32 through the V-shaped tool 46, is transported into the developer tank 24 through the passage opening 23 of the lid 25, and advances downward. The forward end 16 of the film 16
When A reaches the lower end of the developing tank transport path 32, the sensor 3
4 is activated, the controller reverses the pair of transport rollers 35 and 36 based on the output signal of the sensor 34, and the film 16 is
It moves backward and is conveyed upward. Thus, the film 16
However, it is conveyed so as to reciprocate in both up and down directions indicated by an arrow C in FIG. 1, and development processing is performed.

の劣化が起こりにくい。In this way, since the passage opening 23 of the lid 25 through which the film 16 moves in and out of the developing tank 24 along the developing tank transport path 32 is not the minimum necessary opening, and is only one place. The liquid surface opening ratio of the developing solution 30 becomes low, and the progress of air oxidation of the developing solution 30 is significantly suppressed.
Is less likely to deteriorate.

作用、効果が奏せられる。Next, also in the fixing tank 26, the opening ratio of the liquid surface of the fixing liquid 30 is reduced, and the fixing tank transport path 64 is provided.
The film 16 serves as a common path for advancing and retreating, and the fixing tank transport path 64 can be shortened, and the same action and effect as the developing tank 24 can be obtained.

現像処理が可能となる。The film 16 is composed of a pair of conveying rollers 3.
The development time can be changed by increasing or decreasing the rotation speeds of the films 5 and 36 to adjust the transport speed of the film 16, and thus the appropriate development processing according to the type of the film 16 and the like can be performed.
