ABSTRACT:
A conveyance system incorporated in photographic treatment equipment or apparatus in which various photographic treatments are performed for an exposed but undeveloped long length photosensitive material comprising a conveyance passage which is formed with guiding grooves, through which the travelling photosensitive material is conveyed forward with its edges on both sides fit into said guiding grooves, a group of conveyance members having a distance shorter than the length of the travelling photosensitive material and protruding into the both guiding grooves of the conveyance passage so as to clamp the travelling photosensitive material at its edges on both sides, and photosensitive material curving members located along the central position between both guiding grooves so as to ensure increased resistibility against longitudinal warping of the travelling photosensitive material by pressing the same along the central position thereof and positively bending it to a certain circular arch with the aid of the aforesaid guiding grooves.
