ABSTRACT:
Small apparatus for developing photosensitive materials, in particular table-top apparatus, comprises a housing divided by partitions into a plurality of processing stations, for example a developing station, a fixing station and a washing station. Each of the stations comprises a trough containing the respective processing liquid. The photosensitive material to be developed is conveyed by transport rolls from an inlet, through the successive stations and out of an outlet. Liquid in a trough is circulated by a device comprising a magnetic rotor which rotates in a submerged rotor housing in the trough and has inlet openings in its cover and a tangential outlet opening in its periphery. The rotor is rotated by a rotating magnetic field arrangement outside the trough. In one embodiment it comprises a motor-driven permanent magnet. In another, it comprises magnetic coils arranged in a circle and energized sequentially.
