Patent number: 5813783Abstract: Two intermediate gears are respectively disposed between a driving gear and a driven gear so as to mesh with both thereof. The driving gear is driven by a pulse motor. The driven gear is integrally rotated with a capstan roller. Rotational velocities of the intermediate gears are different each other due to eccentricity of the driving gear. The driven gear is always rotated by the faster one of the intermediate gears so that influence by unevenness of rotational velocity of the driving gear is reduced. Accordingly, unevenness of conveying velocity for a recording paper may be reduced. Instead of disposing of the intermediate gears, two drive transmission systems may be arranged. One of the systems comprises a first driving gear and a first driven gear. Other of the systems comprises a second driving gear, a second driven gear and two intermediate gears. The capstan roller is always rotated by the faster one of the systems.Type: GrantFiled: June 24, 1997Date of Patent: September 29, 1998Assignee: Fuji Photo Film Co., Ltd.Inventor: Naoki Takatori

Patent number: 5153734Abstract: A solid state image pickup mounting structure which is used to mount a low pass filter onto the upper surface of a solid state image pickup element and fix them to a reference plate. The mounting structure includes a low pass filter holder formed of an elastic material and having first and second frame portions, and fastening means for fastening and fixing the low pass filter holder through the solid state image pickup element onto the reference plate. According to the mounting structure, the low pass filter is press fitted into the first frame portion of the low pass filter holder and the solid state image pickup element is mounted to the second frame portion in a manner similar to press fitting to thereby form them into a unit with the low pass filter on board the front surface of the solid state image pickup element, and the integrally formed members are then fastened and fixed onto the reference plate by the fastening means.Type: GrantFiled: November 26, 1990Date of Patent: October 6, 1992Assignee: Fuji Photo Film Co., Ltd.Inventors: Shino Kanamori, Naoki Takatori

Patent number: 5151790Abstract: An image pickup device for use in a general image pickup input apparatus such as a video camera, an electronic camera and the like to prevent generation of a false signal or moires. The image pickup device includes an optical filter interposed between a taking lens and an image pickup element. Due to this, the image of an object light is formed by the taking lens at a given image forming position, and a spot image at the image forming position enters the optical filter as a divergent light in a given circle and is then guided through the optical filter to the image pickup element. This can remove space frequency components corresponding to the pixel pitch of the image pickup element and prevent the optical aberrations from being unstabilized.Type: GrantFiled: July 5, 1991Date of Patent: September 29, 1992Assignee: Fuji Photo Film Co., Ltd.Inventors: Naoki Takatori, Masaaki Orimoto

Patent number: 5115267Abstract: A parallax correcting mechanism for a camera having a zoom lens. An objective lens is placed in the optical path of a viewfinder and is movable perpendicular to the optical axis of the viewfinder in cooperation with the focusing mechanism of the associated camera. A movable lens is also placed in the optical path of the viewfinder and is movable along the optical axis of the viewfinder in cooperation with the zoom adjustment of a zoom lens associated with the camera. The movement of the objective lens corrects for any parallax error between the viewfinder and an image seen by the zoom lens of the camera. The movement of the movable lens insures that the field angle of the viewfinder will correspond to that of the zoom lens.Type: GrantFiled: July 24, 1990Date of Patent: May 19, 1992Assignee: Fuji Photo Film Co., Ltd.Inventors: Shigeru Kondo, Naoki Takatori, Masaaki Morizumi, Shino Kanamori
