    • In a film conveyor for use in developing films comprising a first and a second belt racks consisting of a plurality of narrow belts and pressure rollers, and a roller rack consisting of a plurality of squeegee rollers and spray tubes arranged between said two belt racks, the pressure rollers of the two belt racks are so positioned as to press the belts at the mid points of two vertically adjacent squeegee rollers, and the squeegee rollers of the roller rack are arranged in two vertical rows between which an adequate number of said spray tubes are horizontally disposed so that developing solution may be sprayed out directly toward between said two rows of squeegee rollers. Further, the squeegee rollers of the roller rack are driven in synchronism with the moving speed of the belts so as to effect smooth conveyance of the film held between the belts and the squeegee rollers.
    • 在用于显影膜的薄膜输送机中,包括由多个窄带和压力辊组成的第一和第二皮带架,以及由多个刮板辊和布置在所述两个皮带架之间的喷射管组成的滚子架, 两个皮带机架的压力辊定位成在两个垂直相邻的刮板辊的中点处按压皮带,并且辊架的刮板辊布置成两排,其中足够数量的所述喷射管是 水平地设置,使得显影液可以直接喷射到所述两排刮板辊之间。 此外,辊架的刮板辊与带的移动速度同步地驱动,以便实现保持在带和刮板辊之间的胶片的平滑输送。
