Automatic developing device, roller washing method, photosensitive material processing device, and preparation method for processing liquid

摘要

In an automatic developing device, a preheating chamber comprises a heater and a circulation fan for adjusting the heating temperature for a photo polymer plate. A method for washing a roller in a desensitizing processing section is disclosed with a water supply bucket above the roller. A developing section of a processing device comprises a circulation pump and a spray pipe for smoothly substituting the developing liquid in the vicinity of a PS plate. By repeating supplying and stopping of electric power per every half cycle of an alternating current voltage based on the set operation time, the effective voltage is supplied when washing the roller after starting driving of the processing device. A liquid replenishing pattern depends on the configuration of a conveying path in the developing vessel in the processing device and a type of plates.
