Photo-sensitive printing plate automatic developing apparatus.

摘要

A photo-sensitive printing plate automatic developing apparatus (10) for conveying a photo-sensitive printing plate (12) upon which an image has been exposed, along a conveyor route while developing it in a developing tank (14), and then performing at least one of the following processes of washing, rinsing and desensitizing, is provided on the side of the developing tank from which the photo-sensitive printing plates are inserted, and is provided with a pair of insertion rollers (22) that hold said photo-sensitive printing plate and conveys photo-sensitive printing plate downwards at an angle of 20 DEG or less to the horizontal, and a pair of squeeze rollers (48) to squeeze the developing solution on the surface of said photo-sensitive printing plates while holding and conveying them after they have been conveyed drawings, in a state where the maximum radius of curvature of the photo-sensitive printing plate in the developing solution of said developing tank is from 200m to 900m. Accordingly, the photo-sensitive printing plates can be conveyed so as to follow a smoothly curved path through the developing solution.
