ABSTRACT:
An automatic developing apparatus which transports film while preventing treatment liquid from being passed up onto gears and the like located above the surface of the treatment liquid and which prevents treatment liquid from being oxidized or decreasing in quantity. A cylindrical shaft having an axis of rotation normal to a liquid surface of the treatment liquid is positioned so as to cross the liquid surface in order to transmit torque from above the liquid surface to below the liquid surface via a shaft. Since the shaft is rotated about the axis of rotation normal to the liquid surface, the treatment liquid in contact with the shaft is left in contact therewith at a specified height, thereby eliminating the likelihood that the treatment liquid is passed up onto bevel gears, etc. located above the liquid surface via the shaft. Further, the rotation of the shaft about its axis of rotation does not cause the treatment liquid near the liquid surface to be scooped up. This prevents the treatment liquid from being oxidized by mixing with air.
