Publication number: 20090180021Abstract: A lens unit and a sensor unit are held by a lens holding mechanism and a sensor shift mechanism. As the sensor unit is moved in a Z axis direction on a second slide stage, a chart image is captured with an image sensor through a taking lens so as to obtain in-focus coordinate values in at least five imaging positions on an imaging surface. An approximate imaging plane is calculated from the relative position of plural evaluation points which are defined by transforming the in-focus coordinate value of each imaging position in a three dimensional coordinate system. The second slide stage and a biaxial rotation stage adjust the position and tilt of the sensor unit so that the imaging surface overlaps with the approximate imaging plane.Type: ApplicationFiled: January 14, 2009Publication date: July 16, 2009Applicant: FUJIFILM CORPORATIONInventors: Shinichi KIKUCHI, Yoshio NOJIMA

Patent number: 5099734Abstract: A slitter slits a wide web into narrow strips by at least one slitting blade mounted on a shaft member which extends in the transverse direction of the wide web while the wide web is fed in the longitudinal direction thereof. The slitter is provided with a slitting width changing system which has a slitting blade holder which holds the slitting blade and is fitted on the shaft member to be rotatable about the shaft member between a released position in which it can be slid along the shaft member in the longitudinal direction of the shaft member and a locked position in which it is fixed to the shaft member not to slide along the shaft member. A slitting blade shift mechanism rotates the slitting blade holder to the released position, slides it along the shaft member to a position determined according to a desired slitting width, and rotates it to the locked position.Type: GrantFiled: February 25, 1991Date of Patent: March 31, 1992Assignee: Fuji Photo Film Co., Ltd.Inventors: Katuhiro Sugiyama, Yoshio Nojima, Kunihiro Sumida, Shigehisa Shimizu

Patent number: 4972743Abstract: An apparatus for feeding sheets comprises a variable speed conveyor for feeding a sheet cut from a web. A high speed conveyor receives the sheet fed by the variable speed conveyor, and feeds it at a high speed v1. A cutting completion detector detects the separation of the sheet from a cutter and generates a detection signal. A controller adjusts the feeding speed of the variable speed conveyor to a feed speed v2 as long as the leading portion of the web is being fed to the cutter, adjusts the feeding speed to a speed v0 (v0<v1, v2), at which the sheet is kept stationary with respect to the cutter, during the time from when the cutter starts cutting the web to when the cutting is finished and the cut sheet separates from the cutter, and increases the feeding speed from the speed v0 to the speed v1 during the time from when the detection signal is generated to when the sheet arrives at the high speed conveyor.Type: GrantFiled: May 16, 1989Date of Patent: November 27, 1990Assignee: Fuji Photo Film Co., Ltd.Inventor: Yoshio Nojima
