Patent number: 9846350Abstract: There is provided a lens barrel that can easily and reliably prevent an erroneous operation at the time of switching of a manual focus mode. A lens barrel body houses an imaging optical system including a focus lens. A focus operation ring rotates integrally with a first connection ring about an optical axis of the imaging optical system. A second connection ring is movable between an engagement position at which the second connection ring is engaged with the first connection ring and a cam ring and a disengagement position at which the second connection ring is not engaged with both of the first connection ring and the cam ring. A switching-operation ring is movable between a rotation-restriction position at which the switching-operation ring moves the second connection ring to the engagement position and a rotation-allowable position at which the switching-operation ring moves the second connection ring to the disengagement position.Type: GrantFiled: May 2, 2017Date of Patent: December 19, 2017Assignee: FUJIFILM CorporationInventors: Yukitaka Takeshita, Mitsuhiko Oka, Yuichi Kawanabe, Yi Pan, Shinji Otsuka, Kazuyoshi Azegami

Patent number: 9791660Abstract: An object of the invention is to provide a camera body of which a manual focus mode can be easily switched. A lens barrel includes an imaging optical system, a first operation ring, a second operation ring, and first and second sensors. The first sensor detects the rotation of the first operation ring and the rotation angle and the rotational direction of the first operation ring. The second sensor detects the angular position of the second operation ring. The imaging optical system includes a focus lens. A camera body includes a body control unit. The body control unit selectively executes a first manual focus mode in which the focus lens is moved according to the rotational direction and the rotation angle detected by the first sensor and a second manual focus mode in which the focus lens is moved according to the angular position detected by the second sensor.Type: GrantFiled: March 27, 2017Date of Patent: October 17, 2017Assignee: FUJIFILM CorporationInventors: Yukitaka Takeshita, Mitsuhiko Oka, Yuichi Kawanabe, Yi Pan, Shinji Otsuka, Kazuyoshi Azegami

Publication number: 20090027507Abstract: An XY stage includes an X stage and a Y stage. The X stage is supported at three points, i.e., two bearings of a first guide shaft, and a first support shaft. The Y stage is also supported at three points, i.e., two bearings of a third guide shaft, and a second support shaft. A CCD holder, which is a stage to be moved, is also supported at three points, i.e., two bearings of a second guide shaft and one bearing of the first guide shaft. The one bearing supporting the CCD holder is opened in the Y direction to be U-shaped so that the first guide shaft is inserted therein, and the first guide shaft is supported on one side of this U-shaped bearing by receiving a biasing force applied by a spring, so that the attitude of the CCD holder in a predetermined direction is defined.Type: ApplicationFiled: July 15, 2008Publication date: January 29, 2009Inventors: Hideo Kobayashi, Yukitaka Takeshita, Keiji Ohkubo
