Publication number: 20070246598Abstract: A reel in which the planarity of a reel plate after insert molding may be ensured. The reel plate is formed into a concave shape, and by insert molding, the reel plate is made substantially flat. When a reel plate is insert molded, the reel plate is deformed in the direction to protrude in the direction to the outside of the reel by shrinkage stress of resin after molding. Therefore, by concaving the reel plate in advance into a concave shape, even if the reel plate is protruded by the shrinkage stress of the resin after insert molding, the amount of protruding may be absorbed by the amount of concaving, and the shape of the reel plate may be made substantially flat. That is to say, the planarity of the reel plate may be obtained. By doing so, the meshing of the reel gear that surrounds the reel plate with the drive gear on the rotation shaft side of the drive device may be improved.Type: ApplicationFiled: April 24, 2007Publication date: October 25, 2007Applicant: FUJIFILM CorporationInventor: Shozo Onmori

Patent number: 7165738Abstract: In this recording media cartridge, a reel around which a recording medium is wound is rotatably received within a case body constituted by coupling upper and lower halves in a face-to-face relationship, the reel is urged toward the lower half by a planar reel presser spring supported on an inner surface of the upper half as in a cantilever, and the reel presser spring is detachably mounted on the inner surface of the upper half, so that the reel presser spring can be collected without damaging components of the cartridge such as the case body, the reel presser spring and a reel lock member. As a result, in this cartridge, the waste materials can be reduced and the impact on the environment can be reduced. The cartridge is effective when different materials are sorted, and the disassembling work can be simplified.Type: GrantFiled: February 26, 2002Date of Patent: January 23, 2007Assignee: Fuji Photo Film Co., Ltd.Inventors: Kazuo Hiraguchi, Wataru Iino, Shozo Onmori
