Patent number: 9010923Abstract: Disclosed are a sheet conveying device and an ink jet recording apparatus capable of conveying a sheet in close contact with a drum without wrinkles. In a sheet conveying mechanism which presses a pressing roller against the front surface of a sheet being conveyed by a conveying drum to bring the sheet into close contact with the outer circumferential surface of the conveying drum, a back tension application device is provided at a position immediately before the sheet enters between the conveying drum and the pressing roller. The back tension application device sucks the front surface of the sheet to apply back tension to the sheet. Therefore, it is possible to prevent slackness of the sheet which enters between the pressing roller and the conveying drum and to prevent the occurrence of wrinkles.Type: GrantFiled: March 1, 2012Date of Patent: April 21, 2015Assignee: FUJIFILM CorporationInventors: Takahiro Inoue, Takehiko Nakayama

Patent number: 8102467Abstract: Provided are a camera module and electronic equipment that are advantageous in alleviating a stress to be imposed on connectors and a flexible substrate at the time of attaching a printed wiring substrate. A first flank 44 of a lens barrel 22 and a second flank 46 thereof intersect each other. An image sensor 26 is mounted with the back surface 26A thereof directed to a flexible substrate. A signal processing unit 30 is formed on a rigid printed wiring substrate 32. A flexible substrate 28 has a projecting portion 50 that projects from an intersectional part 48 at which the first flank 44 and second flank 46 intersect each other. The printed wiring substrate 32 is disposed on the second flank 46 via a temporary lock mechanism 54. The projecting portion 50 of the flexible substrate 28 is folded at the intersectional part 48, a flexible substrate-side connector 52 is coupled to a printed wiring substrate-side connector 56, and an adhesive layer 58 is bonded to the second flank 46.Type: GrantFiled: December 3, 2008Date of Patent: January 24, 2012Assignee: Sony CorporationInventor: Takehiko Nakayama

Publication number: 20100165466Abstract: An optical sheet for display use wherein two or more optical sheets are stacked therein and the optical sheets are joined to one another on one peripheral side of each by a thermoadhesive film is to be provided. Also an optical sheet for display use wherein two or more optical sheets are stacked therein and the optical sheets are joined to one another on two or more peripheral sides of each by a thermoadhesive film is to be provided. Since the optical sheets are joined to one another on one peripheral side or two or more peripheral sides of each by a thermoadhesive film, the step of cutting each of multiple films (sheets) into the product size can be omitted, and so can be the step of stacking multiple layers of films (sheets) while positioning them. Also, it is free from a problem which derives from protective sheets, resulting in advantages in both cost and quality aspects. Moreover, it is free from a problem which arises when multiple layers of films are stacked.Type: ApplicationFiled: November 30, 2006Publication date: July 1, 2010Applicant: Fujifilm CorporationInventors: Keisuke Endo, Takehiko Nakayama, Naoko Saito

Patent number: 7536940Abstract: A clean booth has a conveyor area for carrying recording sheets, and a motor drive area for containing motor and mechanical parts that emit much dust. The conveyor area and the motor drive area are covered respectively, and separated by a frame plate. Moreover, fan filter units blow pressurized clean air into the conveyor area to discharge dust while a ventilation system exhausts air in the motor drive area. There is no airflow from motor drive area to the conveyor area because of the difference in air pressure. The recording sheets in the conveyor area are carried by belt conveyors with artificial suede belts. The artificial suede belt is suitable to be used as a conveyer belt because of low dust emission and sufficient flexibility to prevent flaw or pressure marks on the recording sheets.Type: GrantFiled: December 18, 2002Date of Patent: May 26, 2009Assignee: FUJIFILM CorporationInventors: Takehiko Nakayama, Hiroyuki Nishida, Hideyuki Uezono
