PURPOSE: To execute the check, adjustment, maintenance, etc., of equipments without interrupting development processing by shielding a processing room and a machine room with a light-shielding plate.
CONSTITUTION: A developing room is divided into two rooms, one of two rooms is used for the processing room for developing a photosensitive material, and the other room is used for a machine room housing machines and devices for indirectly processing. In this case, the frame of a developing chamber is composed of the processing room frame 1 of the upper part, the machine room frame 2 of the lower part, and the light shielding plate 3 held between the processing room frame 1 and the machine room frame 2. Then, a printing plate entrance and a printing plate exit are provided on the side surfaces of the entrance and exit sides of the processing room, respectively. Therefore, the light shielding plate 3 shields the gap of the processing room and the machine room, so that even if the machine room is released, external light can not be leaked to the processing room.
