ABSTRACT:
A new and unique apparatus for specially treating photosensitive material in the form of disc films which have been lately developed but have a limited quantity of demand at present is disclosed in which a series of treatments starting with developing and ending with drying are automatically practiced for the disc films inserted in the apparatus. A plurality of treating tanks, a squeeze tank and a drier are arranged in line in the dark box of the apparatus, while a holder insert port is disposed at the one end part and a holder discharge port is disposed at the other end part of the apparatus. A hanger including a rotary disc film supporting shaft at the lower end part thereof so as to carry the disc film to be treated is slidably mounted on a movable rail which is caused to repeatedly practice a series of movements comprising raising, forward movement, lowering and backward movement, accompanied by a temporary stop at the lowermost end position. The disc films are subjected to an intended treatment in each of the treatment tanks while they are rotated on a disc film supporting shaft rotatably held on the hanger. Further, a hanger displacement prevention system including a rotational force transmission mechanism and a hanger backward movement prevention member is provided for the purpose of inhibiting backward movement of the hanger a little bit before the movable rail reaches the lowermost end position.
