PURPOSE:To uniformize development with a small volume of a fresh developing soln. by boring plural pieces of discharge ports to the end of a supply pipe for feeding the developing soln. and enclosing these parts with flat plate sheets which have the front ends formed to a nozzle shape, and dropping the developing soln. from the nozzle at the time of coating a small volume of the developing soln. on a printing plate such as PS plate which is carried to the developing device. CONSTITUTION:The developing soln. is dropped and coated on the surface of the PS plate 101 at the time when the PS plate 101 pinched by a pair of carrying rollers 2A, 2B passes on a guide roller 2C. A base slit nozzle part is disposed above the roller 2C for the above-mentioned purpose and is constituted in the following manner: The developing soln. fed by a cylindrical pipe 31 is received by the developing soln. supply square pipe 21 provided with plural pieces of the discharge ports on the outside circumference and the discharged developing soln. is blown down in polyethylene terephthalate base materials 28, 29 enclosing the pipe 21 and is dropped through the nozzle 39 at the throttled bottom end onto the PS plate 101. |
