PURPOSE:To obtain a device for treating a photosensitive lithographic printing plate Without need for maintenance over a long period at the time of cleaning the developed plate with a small amt. of cleaning soln. and without adversely affecting the succeeding stage. CONSTITUTION:A main power source is turned on when the operation of the device is started, namely, the first thing in the morning, and a pump 304 is driven while an operating switch is turned on and the temp. of the developer, etc., in a developing tank 18 is controlled to discharge washing water from a discharge nozzle 300. Meanwhile, the rotation of conveyor rollers 52 and 53 is started in a washing part 24 as the pump 304 is driven. The washing water in a pan 62 used until the previous day is allowed to overflow by the discharge of the washing water from the nozzle 300, and fresh washing water is stored. Since the washing water is replaced, silicate scum, etc., are not deposited, the nonuniform coating of a liq. gum is not caused in the succeeding stage, and the solidification in the pan 62 due to long standing is prevented. |
