Abstract

PURPOSE:To circulate processing liquid to the image forming surface of a film uniformly and to eliminate an irregularity in the development of a photosensitive material by providing a processing liquid circulating means to the disk film fitting part of a conveyor leader body. CONSTITUTION:When a disk film 56 is processed, the fitting hole of the film 56 is inserted through the fitting hole of the conveyor leader 15, which is conveyed along an insertion guide and sent to a processing tank. When the disk film 56 is guided by the conveyor leader 15 and conveyed in processing liquid, the processing liquid flows in and out of the guide hole 15d of the conveyor leader 15 to circulate the liquid uniformly on the image formation surface 56b of the disk film 56. Further, processing liquid circulates uniformly on the image formation surface 56a in a next-stage processing tank to reduce the irregularity in the development. Thus, the guide hole 15d as the circulating means for processing liquid is provided to perform uniform development.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a conveyance leader for a photosensitive material processing apparatus that processes a disk film by passing it through a processing liquid.

(Background of the Invention) For example, there is a disc-shaped disc film as a photographic light-sensitive material.This disc film has a different shape from a strip-shaped roll film, and there is a difference in processing time. Because it is difficult to process the photosensitive material using a processing device, it has been processed using a dedicated device.
