Patent number: 6427306Abstract: When any of facilities of a film producing and packaging system suffers a failure, a film processing controller shuts off the film producing and packaging system. The operator repairs a failing facility and manually discharges a length of an elongate film which may possibly be defective. After the failing facility is repaired, the film processing controller is restarted to operate the film producing and packaging system, which then automatically discharges a length of the elongate film corresponding to a preset number of sized films. It is possible to easily and quickly discard a portion of the elongate film which has been made defective by the facility failure.Type: GrantFiled: July 17, 2001Date of Patent: August 6, 2002Assignee: Fuji Photo Film Co., Ltd.Inventors: Hideyuki Karaki, Chiaki Suzuki, Yoshinobu Misumi, Takayuki Kambara, Susumu Sato

Patent number: 6061898Abstract: An apparatus for assembling a photo film unit has a dark box, which has supply openings into which parts are supplied, and an exit opening from which the body loaded with the photo film is exited. Intermediate cells of the dark box shield ambient light and include interlocked outer shutter plates and inner shutter plates which are disposed in the supply openings and the exit opening. A cassette supplying loader and a robot hand transfer the cassette into the dark box, while a leading tongue of the photo film is protruded from the cassette shell, with a remaining portion of the photo film contained as a roll. A roll forming fork device winds the photo film to a predetermined length from the cassette and forms the photo film into the roll. A photo film mounting mechanism swings the roll and the cassette shell together to change orientation thereof, and loads the roll and the cassette shell into the body.Type: GrantFiled: September 10, 1998Date of Patent: May 16, 2000Assignee: Fuji Photo Film Co., Ltd.Inventors: Chiaki Suzuki, Yuzo Tsunekawa
