Arrangement for developing photomaterials in rotatable drum

摘要

An arrangement for developing photomaterials has a rotatable drum arranged to accommodate a photomaterial, a plurality of vessels for various treatment fluids, an arm having a free end rotatably connectable with the drum and turnable together with the latter between a substantially horizontal initial position for supplying a treatment fluid from one of the vessels into the drum for treatment of the photomaterial and an inclined emptying position for discharging a used treatment fluid from the drum after the treatment, a guide arranged so that the vessels are located near one another in a stack and displaceable to the drum for filling the latter, a stepping element including the arm and arranged to displace the vessel of the stack by a respective one of the vessels in a cycle with the turning of the arm, and a lifting member provided on the arm and arranged so as to upwardly tilt the vessel which has been displaced to the drum, to its pouring position of the treatment fluid.
