ABSTRACT:
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.
