Patent number: 6205060Abstract: In a production process of a photo film cartridge, data relating to respective components and data obtained during the production process is written in an IC memory that is mounted to a cartridge shell of the photo film cartridge. The data written in the IC memory is read out at later stages of the production process for use in controlling production of the photo film cartridge. The data is at least partly maintained stored in the IC memory after the shipment, for use in tracing production history of the photo film cartridge. When a photo film cartridge having an IC memory is for use in a lens-fitted photo film unit, unit type data indicating the type of the film unit are written in the IC memory before loading the photo film cartridge in the film unit. The unit type data is read out from the IC memory to choose a proper type of packaging materials for the film unit before a unit body of the film unit is wrapped and packed in the packaging materials.Type: GrantFiled: June 8, 1999Date of Patent: March 20, 2001Assignee: Fuji Photo Film Co., Ltd.Inventors: Akihiro Sanda, Shoichi Uchida, Hiroshi Hara, Kazuhito Iwase

Patent number: 5772495Abstract: A photo filmstrip (14) of a regular length (L) is produced from photo film web (45) having a predetermined width (W). The photo filmstrip and the photo film web have a back surface, an emulsion surface, a pair of lateral edge faces (45a), and four corner edges (45b, 45c) defined between the back surface, the emulsion surface, and the lateral edge faces. At least one of the lateral edge faces and at least one of the corner edges of the photo film web are abraded while the photo film web is conveyed. Photo film dust, created in the abrasion is eliminated from the photo film web. Perforations (34) are formed in the photo film web. The photo film web is cut by the regular length into the photo filmstrip, which is wound into a cassette shell.Type: GrantFiled: September 13, 1996Date of Patent: June 30, 1998Assignee: Fuji Photo Film Co., Ltd.Inventors: Akihiro Sanda, Fujio Kuwabara, Naoki Sakai

Patent number: 5484251Abstract: An apparatus for overturning a long-web roll comprises chucks for holding the long-web roll, which is placed on a first resting surface, by nipping an outer circumference of the long-web roll from both sides in the radial direction, and stop plates capable of being set at supporting positions that stand facing a front end face of the long-web roll, which is held by the chucks, the front end face being directed towards the side of a second resting surface. A rotating transfer device rotates the stop plates and the chucks together with each other by an angle of approximately 90.degree. and thereby places the long-web roll, which is held by the chucks, on the second resting surface such that the front end face may rest on the second resting surface.Type: GrantFiled: October 31, 1994Date of Patent: January 16, 1996Assignee: Fuji Photo Film Co., Ltd.Inventor: Akihiro Sanda
