In the FD tank, the hanger movement by the horizontal feeder is stopped, delayed,
By controlling the progress in various combinations, the development time of the continuously fed film is adjusted by adjusting the length (decrease or decrease) of the development time, and the desired development of each film is obtained.

(Problems to be Solved by the Invention) As described above, in the transfer device of this kind of automatic developing machine, in the case of the sensitized development process among the sensitized development processes, the sent film is usually stored in the FD tank. (Normal) The sensitized development processing was carried out by temporarily stopping and delaying the transverse feeder in order to immerse it in the processing solution for a longer time. Therefore, during the sensitized development process, the subsequent films hung on the hanger must wait for processing in order to delay the timing of the lifting device for FD to the traversing device. There was a problem that the development processing was delayed, which reduced the efficiency of the development processing in the automatic development processor.

This invention efficiently develops an underexposed film that requires sensitizing development without obstructing the flow of a properly exposed (normal) film that can be developed in the subsequent normal processing (time). It is an object of the present invention to realize a transport device in an automatic processing machine that operates.

(Means for Solving the Problems) In order to achieve the above object, the present invention is to automatically move a film suspended on a hanger into each processing tank sequentially by using a lifting device and a traversing device to immerse the film. In the transfer device of the automatic development processor that performs development processing, on the upstream side along the hanger transport direction of the horizontal feeder start position of the FD (first development) tank corresponding to the lowering position of the lifting device for FD (first development), A single moving device for sensitization processing that operates in the forward and reverse directions along the hanger transport direction is provided adjacently, and the single moving device for sensitization processing operates in reverse according to the data of the indicated film to perform FD (first Developing) The film hanger at the start position of the lateral feeder in the tank is retracted and retracted from the hanger transport path, and after a lapse of time according to the data, the single moving device for sensitization processing is rotated forward and the film being retracted. A photographic material automatic development processor that advances the hanger to the hanger transport path at the start position of the lower lateral feeder and transfers it, and then transports the film properly by the lateral feeder to automatically develop the film. And a process selection mechanism for detecting the data of the designated film is provided, and the data of each film is detected and selected during the conveyance, and the single moving device for the sensitization process is automatically operated correspondingly. By doing so, the development process for the sense of increasing or decreasing the film can be performed more efficiently.
