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: 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

Publication number: 20020148822Abstract: 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.Type: ApplicationFiled: March 26, 2002Publication date: October 17, 2002Applicant: FUJI PHOTO FILM CO., LTD.Inventors: Ryoei Nozawa, Akinori Kimura, Shinichi Matsuda, Takayuki Iwamoto, So Konno, Toshihiro Suya, Hideto Yamamoto, Miyuki Endou

Patent number: 5346201Abstract: Disclosed herein is a device for feeding sheets, one by one, from a stack of sheets stored in a sheet placement unit. The sheet feeding device basically comprises suction cups or pads facing one end of the edge of an uppermost sheet of the stacked sheets, for taking out the uppermost sheet, an engaging member located at the sheet placement unit, for supporting the leading ends in the withdrawal direction of the stacked sheets, and a roller disposed near the engaging member and positioned to face a cut-away portion in a portion of the engaging member facing the opposite end of the uppermost sheet, the opposite end being spaced away from the suction pads. The cut-away portion is formed to prevent the opposite end of the uppermost sheet from contacting with the engaging member due to hang down of the uppermost sheet. In addition, the cut-away portion is inclined downwards toward the opposite end of the uppermost sheet from the one end thereof.Type: GrantFiled: May 26, 1993Date of Patent: September 13, 1994Assignee: Fuji Photo Film Co., Ltd.Inventor: Toshihiro Suya

Patent number: 5295673Abstract: Photographic light-sensitive mediums such as sheets are fed one by one by a suction pad in a sheet-feed control device. The suction pad is displaced downward at a low speed in a position near a stack of sheets so as to approach an uppermost one of the sheets, thereby attracting the uppermost sheet to the suction pad, and the uppermost sheet is flexed by a sheet presser while it is being separated away from the other sheets. Then, a judgement is made as to whether the suction pad attracts either a single sheet or a plurality of sheets, by detecting the magnitude of the flexion of the sheet or sheets attracted. Then, the suction pad is displaced again toward the position where the uppermost sheet is to be attracted, when it is detected that the suction pad has attracted the plurality of sheets. At this time, the suction pad is placed in a given stop position, thereby releasing the plurality of sheets from the suction pad.Type: GrantFiled: November 29, 1991Date of Patent: March 22, 1994Assignee: Fuji Photo Film Co., Ltd.Inventors: Nobuyuki Torisawa, Toshihiro Suya, Norikazu Soga

Patent number: 5257776Abstract: Sheets such as photographic films are fed one by one by suction cups in an image recording system. A resilient sheet separator is brought into abutment against an uppermost one of stacked sheets, and then the suction cups are moved toward the uppermost sheet. Before the suction cups reach the uppermost sheet, they are activated to attract the uppermost sheet under suction. The sheet separator pushes the uppermost sheet in one direction and the suction cups draw the uppermost sheet in the opposite direction, so that the attracted uppermost sheet is greatly flexed fully out of contact with the next sheet of the sheet stack. Thereafter, the suction cups and the sheet separator are displaced away from the sheet stack, separating the uppermost sheet from the sheet stack. A detecting arrangement detects whether the suction cup attracts a single sheet.Type: GrantFiled: April 22, 1992Date of Patent: November 2, 1993Assignee: Fuji Photo Film Co., Ltd.Inventors: Toshihiro Suya, Nobuyuki Torisawa, Norikazu Soga, Issy Matsuda
