PURPOSE: To minimize the size of a dedicated black box regardless of the housing state of a photosensitive material by making it movable horizontally and in parallel without fixing it to a photographic processing machine.

CONSTITUTION: A feeding roller 3 is provided in the supply part of the photosensitive material 1 and the outputted material 1 is housed in an output magazine 4. Besides, the magazine 4 is loaded on a dedicated black box 5. Then, the position of the box 5 is not fixed to a photographic processing machine main body 2 and it is set to be movable horizontally and in parallel with respect to the roller 3. Therefore, when the material 1 is housed at the reference of the center of the magazine 4 or housed at the reference of the end part thereof, it can be processed by adjusting the position of the box 5 with respect to the main body 2. That means, the minimum-sized box 5 on which the magazine 4 can be loaded is obtained.
