Patent number: 5543888Abstract: A camera capable of operating in a red-eye prevention mode. The camera has an electronic flash device which is activated by a drive circuit in synchronization with the exposure. The electronic flash device also serve as a pre-light-emission device capable of performing pre-light-emission for the purpose of preventing red-eye effect. When it is judged from photographing condition that red-eye effect may occur, a controller activates the electronic flash device to effect a pre-light-emission for reducing the size of pupils of eyes of a person to be photographed, before the main flashing which is executed in synchronization with the exposure.Type: GrantFiled: June 7, 1995Date of Patent: August 6, 1996Assignee: Nikon CorporationInventors: Toshio Sosa, Toru Fukuhara, Toshio Dobashi, Masaharu Hara, Norikazu Yokonuma

Patent number: 5526085Abstract: The invention is directed to an electrical connecter, mounted on a mounting board within a camera, to which an FPC board is connected, that does not increase the size of the camera, and is a simplified shape and structure. The main camera body is equipped with a flat portion on one portion of the outer wall that forms a film chamber comprising either a cartridge chamber or a spool chamber. A mounting board has a section that faces and is substantially parallel to the flat portion and an extension section that does not face the flat portion. A horizontal or vertical electrical connecter is attached to the extension section of the mounting board on the surface generally facing the outer wall of the film chamber and an electrical board comprising an FPC board or the like is connected to the electrical connecter. To enhance the features of the camera, a first electrical component is loaded on the surface of the mounting board opposite to the electrical connector loaded surface.Type: GrantFiled: January 24, 1995Date of Patent: June 11, 1996Assignee: Nikon CorporationInventors: Masaharu Hara, Fumiya Taguchi, Nobuaki Sasagaki, Suminori Watanabe

Patent number: 5521670Abstract: A carefully designed arrangement of an electrical board and an FPC board connected by electrical connectors in a camera. The reliability of electrical connections is improved, and of a higher quality. An FPC board or the like, is positioned along top side wall surfaces of a prism inside a main camera body. An electrical board, such as a rigid board or the like, is positioned along a flat surface on the main camera body that extends in an approximately horizontal direction adjacent to the side wall surface. A two-surface mount-style mounting board is positioned between the top side wall surface and the flat surface in an approximately vertical direction. A horizontal electrical connector is positioned to receive the FPC board mounted on the surface of the side wall surface side of the mounting board. A vertical electrical connector is provided to receive the electrical board surface of the flat surface side of the mounting board.Type: GrantFiled: January 25, 1995Date of Patent: May 28, 1996Assignee: Nikon CorporationInventors: Masaharu Hara, Jirou Asami, Suminori Watanabe

Patent number: 5349416Abstract: A display apparatus is composed of a first emission element, a second emission element different from the first emission element in emission color, and a reflecting member for displaying by reflecting light from the second emission element. The reflecting member has a color which is a substantially complementary color to the emission color of the first emission element, so that it does not reflect light from the first emission element, but reflects light from the second emission element.Type: GrantFiled: October 6, 1993Date of Patent: September 20, 1994Assignee: Nikon CorporationInventor: Masaharu Hara
