Apparatus for transporting disc films

Abstract

An improved apparatus for transporting disc films in a developing apparatus which includes a series of treatment liquid baths. The apparatus includes a support block by means of which a movable rail is supported so as to allow a hanger to slide therealong. The hanger is provided with a rotational shaft at the lower end thereof on which a plurality of disc films to be treated are carried. The support block is adapted to slide along a shaft which extends in parallel with the direction of transportation of the hanger and moreover it is adapted to turn about the shaft. The apparatus further includes a chain-sprocket mechanism which is operatively associated with the support block via a connecting rod and a moving member. During upward movement and lowering movement of the moving member the support block is caused to turn forwardly and backwardly whereby the disc films carried on the hanger are introduced into treatment liquid and removed therefrom. During forward movement of the moving member the hanger is transported to the next operative position located above the next treatment liquid bath while the disc films are raised up above the treatment liquid bath. During backward movement of the moving member a stopper becomes effective for allowing only the movable rail to move back while the disc films are kept to be immersed in treatment liquid in the next treatment liquid bath.
