Patent number: 7422383Abstract: Developer is supplied to a first spray pipe disposed in a developing bath. The inside of the developing bath is provided with a heater. A liquid-flow generating unit comprises a liquid-flow generating head and a branch duct, which is connected to a branch pipe of the first spray pipe via a rubber hose. A part of the developer flowing in the first spray pipe is forwarded to the liquid-flow generating head. By a gap-forming ring, a gap is secured between an outer surface of the heater and an inner surface of the liquid-flow generating head so that the developer uniformly flows along the outer surface of the heater in a longitudinal direction thereof. A heater cover is attached to the liquid-flow generating head. An inner surface of the heater cover inclines in the longitudinal direction of the heater.Type: GrantFiled: August 1, 2005Date of Patent: September 9, 2008Assignee: FUJIFILM CorporationInventors: Ryoei Nozawa, Hideto Yamamoto, Toshihiro Suya, Daisuke Hibe, Keiichi Adachi

Patent number: 7083038Abstract: 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.Type: GrantFiled: November 2, 2004Date of Patent: August 1, 2006Assignee: Fuji Photo Film Co., Ltd.Inventors: Ryoei Nozawa, Shinichi Matsuda, Takayuki Iwamoto, So Konno

Patent number: 7074005Abstract: An intermediate guide member is provided attachable and removable between a head portion and a supporting frame of a stocker for printing plates. A number of intermediate guide members is an element to set a time of starting downward movement of hooks supporting a leading end of a printing plate. Three conditions in accordance with lengths of non-detection times are set for detecting the printing plate to judge authenticity of the detection. When the hooks reach vicinities of stoppers provided at supporting bars of a reversal unit, the hooks swing, are pulled-in from above the slope, and transfer the printing plate to the stoppers. Thereafter, by rotating the supporting bars and the stoppers integrally around a shaft, the printing plate is pivoted over toward a back plate, and a lower end of the printing plate is transferred from the stoppers to a receiving plate without damaging the printing plate.Type: GrantFiled: October 22, 2004Date of Patent: July 11, 2006Assignee: Fuji Photo Co., Ltd.Inventors: Ryoei Nozawa, Hidenori Sasaki, Takanobe Nakamura, Shinji Odagiri, Tatsuya Fujita, Mutsumi Ashizawa, Kazuyoshi Takahashi

Patent number: 6910815Abstract: 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.Type: GrantFiled: September 24, 2002Date of Patent: June 28, 2005Assignee: Fuji Photo Film Co., Ltd.Inventors: Ryoei Nozawa, Shinichi Matsuda, So Konno, Yasuhiro Endo, Hideaki Iijima

Patent number: 6902330Abstract: A printing plate processing apparatus provides a step in which a printing plate which has undergone image exposure is processed by being immersed in a developing solution, and the printing plate is delivered while the developing solution is being squeezed out from the printing plate by a conveying roller pair which is partially immersed in the developing solution. A stoppage time of the apparatus is measured, and the conveying roller pair is driven to rotate for an amount of time set in accordance with a measured result of the stoppage time when operation of the apparatus is started, thereby allowing the conveying rollers to be cleaned. A concentration of carbon dioxide in an environment in which the apparatus is installed is detected, and based on the detected result and the measured result of the apparatus stoppage time, the driving time of the conveying roller pair is set.Type: GrantFiled: September 29, 2003Date of Patent: June 7, 2005Assignee: Fuji Photo Film Co., Ltd.Inventors: Ryoei Nozawa, Takayuki Iwamoto, Akinori Kimura

Patent number: 6655860Abstract: A brush roller is structured such that a web body having wire members is wound in a helical manner around a roller main body to which an axial end member is mounted. A fastening member is mounted to a rotary shaft of the axial end member, and one end of the web body is fixed to a holding member which is arranged between the fastening member and the axial end member so as to freely rotate relatively. The holding member relatively rotates in a winding direction due to an urging force of a torsional coil spring when elongation occurs in the web body, thereby preventing slack from occurring in the web body.Type: GrantFiled: June 7, 2001Date of Patent: December 2, 2003Assignee: Fuji Photo Film Co., Ltd.Inventors: Ryoei Nozawa, Hideto Yamamoto, Shinichi Matsuda

Patent number: 6652167Abstract: In a shutter facing an aperture portion in a partition plate in a photosensitive material processing device, a blocking member, formed substantially in a semicircular cylindrical shape, is placed by the rotation of a shaft between blades thereby closing the aperture portion. The opening between the blades is opened by rotating the blocking member integrally with the shaft so that a photosensitive material can pass through. Multi-leveled surfaces are formed on the top surface of a guide plate. Aperture portions for mounting rollers with adaptors are formed in an alternating pattern on the surfaces. A plurality of protruding guide ribs are provided extending across the surfaces. A plurality of brush roller parameters are adjusted so that a winding mark index defined by the parameters falls within a predetermined range. Rollers are washed when a finisher control system is restarted after an unforeseen long stoppage.Type: GrantFiled: June 24, 2002Date of Patent: November 25, 2003Assignee: Fuji Photo Film Co., Ltd.Inventors: Ryoei Nozawa, Toshihiro Suya, Takayuki Iwamoto
