Abstract: A photosensitive material processing device for processing a photosensitive material with a processing liquid while conveying the photosensitive material by a roller pair. A driving device for providing a rotation drive to the roller pair. A drive controlling device that gradually raises voltage of the electric power at the time of starting the rotation drive of the roller pair.

Abstract: A roller washing method for a photosensitive material processing device. The processing device processes a photosensitive material with a processing liquid while conveying the photosensitive material with a conveying roller. An idle roller is disposed in contact with a circumferential surface of the conveying roller. The circumferential surface of the conveying roller is washed by rotating the conveying roller while supplying washing water to an area where the conveying roller and the idle roller contact each other.

Abstract: A photosensitive material processing device for processing a photosensitive material with a processing liquid while conveying the photosensitive material by a roller pair. A driving device for providing a rotation drive to the roller pair. A drive controlling device that gradually raises voltage of the electric power at the time of starting the rotation drive of the roller pair.

Abstract: The present invention provides a photosensitive material processing apparatus in which a photosensitive material is processed with a processing solution. Reliable liquid displacement in the vicinity of the surface of a photosensitive material, and uniform temperature adjustment can be performed. Also, damage or a transport deficiency, caused by a corner of the material coming into a through hole when a conveyance path of the photosensitive material is formed can be prevented. When pre-washing processing is carried out prior to development processing using a developer, processing unevenness in which an overcoat layer partially remains can be prevented. An operation of mounting and removing conveyance rollers disposed in a pair is facilitated and a proper nipping force can be imparted between a conveyance roller pair. Mounting of a replenisher case filled with a replenisher is facilitated and a replenisher is kept from remaining in piping or in a replenisher case.

Abstract: The present invention provides a photosensitive material processing apparatus in which a photosensitive material is processed with a processing solution, specifically, a photosensitive material processing apparatus in which: reliable liquid displacement in the vicinity of the surface of a photosensitive material, and uniform temperature adjustment can be carried out; damage to a photosensitive material such as a printing plate, or transport deficiency, caused by a corner of the photosensitive material coming into a through hole when a conveyance path of the photosensitive material is formed can be prevented; when pre-washing processing is carried out prior to development processing using a developer, processing unevenness in which an overcoat layer partially remains can be prevented; an operation of mounting and removing conveyance rollers disposed in a pair is facilitated and a proper nipping force can be imparted between a conveyance roller pair; and mounting of a replenisher case filled with a replenisher

Abstract: 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.
