Abstract
A photo-sensitive printing plate automatic processing apparatus for holding a photo-sensitive printing plate upon which an image has been exposed, between pairs of conveyor rollers and processing it by processing liquids while conveying it along a conveyor path, has pipe members having spray outlets for spraying processing liquid, supported at both their ends on both sides of the conveyor rollers. One of the ends of each of these pipe members is provided with a spring to predispose the pipe member in the directioln of the other end and to also enable the pipe member to be moved against the spring force. Therefore, the pipe can be moved to oppose the spring force and therefore removed from the side plate.
