PURPOSE:To develop films, one by one, uniformly, by providing a film winding means for upper rollers, lower rollers, etc., film holding frame with transmission means of gears, levers, etc. CONSTITUTION:Film holding frame 10 has a couple of left and right side plates 11 and 11', a couple of upper shaft 12' and lower shaft 13' coupling those side plates, and upper roller 12 and lower roller 13 equipped rotatably to upper shaft 12' and lower shaft 13'. Further, film holding frames 10 are suspended by chain 2 successively and steeped in respective processing liquids A, B... in a developing vessel successively as chain 2 rotates. Furthermore, lever 17 of film holding frame 10 is moved in cam groove 29 of cam plate 28 via rod 18. As a result, film 7 never stays stuck to the upper or lower roller at any part in the processing liquids and is developed, one by one, uniformly. |
