Abstract: An apparatus for developing dental X-ray film of the dip and dunk type, in which the apparatus is provided with a plurality of processing stations disposed in an arcuate path that is concentric about a vertical axis, which stations comprise loading, developing, rinse, fix, final rinse, drying, and unloading stations, with the developing, rinse, fix, and drying stations being defined by open topped receptacles. The individual films are clipped to special film hangers which are removably suspended from a cantilevered support that rotates intermittently about the said vertical axis, and also is moved vertically to dispose the individual hangers elevationally to move between stations and then lower the hangers into the respective receptacles for the processing to be performed there, in which position the hanger support reciprocates vertically for purposes of agitating the film in its bath.
