Patent number: 6591489Abstract: A photographic film cassette manufacturing apparatus, has a perforator for providing a long film with perforations and a cutter for cutting the long film into individual filmstrips to be contained in the film cassette driven synchronously with transport of the long film. A magnetic recording head for recording data on a magnetic recording layer of the long film is driven in synchronism with the perforator and the cutter. The long film is transported in a first direction before being cut into the individual filmstrips. In cooperation with the cutting, a trailing end of the individual filmstrip in the first direction is moved in a direction which is reverse to the first direction to secure the trailing end to the spool. A cassette shell consisting of a pair of shell halves is temporarily assembled by mating the shell halves together while containing a spool inside the shell halves, and thereafter opened to an extent that confining elements still confine the position of flanges of the spool.Type: GrantFiled: June 12, 2002Date of Patent: July 15, 2003Assignee: Fuji Photo Film Co., Ltd.Inventors: Makoto Shimizu, Toshiro Esaki, Tadayoshi Shibata, Koichi Takahashi

Patent number: 5765474Abstract: A photo film cassette has a spool about which photo film is wound. A data disk is disposed near to an axial end of a core of the spool. To record a bar code on the data disk in manufacturing the photo film cassette, a hot stamping apparatus includes at least one spool holder for holding the spool in a slidable manner while the core is erect and the data disk is oriented upwards. A disk support supports the data disk. A slider shifts the disk support between a retracted position away from the spool holder and an advanced position close to the spool holder. The disk support in the advanced position is adapted to lift the data disk by contact with a bottom of the data disk. A hot stamping head is pressed against a top of the data disk, and records a bar code thereto. Cushion springs are biasing the disk support up toward the hot stamping head.Type: GrantFiled: November 20, 1996Date of Patent: June 16, 1998Assignee: Fuji Photo Film Co., Ltd.Inventors: Toshiro Esaki, Masayoshi Wada, Hideki Matsuzawa

Patent number: 5462240Abstract: A photographic film cassette assembling method includes the steps of joining shell halves together by ultrasonic welding, to form a cassette shell, while accommodating a spool in the cassette shell. A film connection sheet is secured to the spool before the spool is mounted in the cassette shell. A free end of the film connection sheet is placed outside the cassette shell through a film passage mouth of the cassette shell. A strip of a photographic film is connected to the spool by attaching a trailing end of the photographic film to the free end of the film connection sheet and wound about the spool by rotating the spool. The photographic film may be directly secured to a spool having an engaging member formed therein and a film guide member formed integrally therewith. A free end or free ends of the guide member protrude slightly from the film passage mouth to the outside of the cassette shell.Type: GrantFiled: July 15, 1993Date of Patent: October 31, 1995Assignee: Fuji Photo Film Co., Ltd.Inventors: Toshiro Esaki, Mituru Suzuki, Susumu Sato, Kohichi Takahashi, Makoto Shimizu

Patent number: 5437828Abstract: A plurality of shapes each having a fundamental construction of a flange are vacuum formed on a continuous sheet of thermoplastic resin. When blanking each of the formed shapes out of the resin sheet into an individual flange, a spool core is placed coaxially with the formed shape placed in the blanking position. The flange just blanked out of the resin sheet is moved in the blanking direction toward the spool core, to be fit on the spool core. The shapes are formed in a double line along the resin sheet, and thereafter, the resin sheet is slit along the longitudinal direction into two sheet branches each having the formed shapes arranged in a single line. The back side surfaces of the two sheet branches are opposed to each other, and the spool core is disposed between the sheet branches and oriented in a direction perpendicular to the back side surfaces of the sheet branches. The formed shapes are blanked out of the sheet branches in opposite directions toward opposite ends of the spool core.Type: GrantFiled: June 24, 1993Date of Patent: August 1, 1995Assignee: Fuji Photo Film Co., Ltd.Inventors: Makoto Shimizu, Mituru Suzuki, Susumu Sato, Koichi Takahashi, Toshiro Esaki
