ABSTRACT:
A machine for treating photosensitive material in the form of disc films including an enclosure having a series of treating tanks for conducting treatments of disc films, a rotatable support for holding at least one disc film and a support rotatably supporting the rotatable support. A mechanism is provided for moving the support and for placing a disc film held on the rotatable support into solutions contained in the treating tanks. The disc film held on the rotatable support SR is rotated when placed in the treating solutions contained in the treating tanks by the action of a fluid jet against blades on the rotatable support. A first member supported in the enclosure is movable up and down in a vertical direction to respectively remove a disc film from and place a disc film in one of the treating tanks. A groove in the first member slidably engages the support so that the support can move in a longitudinal direction with respect to the first member. A second member supported in the enclosure for movement back and forth in the longitudinal direction has tongues thereon for engaging the support and for moving the support in the longitudinal direction during movement of the second member in the longitudinal direction when the first member is raised and held stationary with respect to the second member. The machine for treating disc films is also combined with a machine for treating roll films such that the same treating tanks are used for treating both types of films.
