  • Patent number: 5614974
    Abstract: A camera having improvements in (a) the placement of anti-vibration sensors, (b) the connection between components of an anti-vibration mechanism, (c) the connection between the anti-vibration mechanism and external testing devices and (d) the connection of the camera to a tripod. The camera body has first and second ends and a photographic lens which is positioned on the camera body between the first end and the second end. A battery compartment, first and second anti-vibrations sensors and a main capacitor are all positioned in the first end of the camera body. The first anti-vibration sensor is positioned between the battery compartment and the photographic lens. The first and second anti-vibration sensors reside on the same sensor card and the sensor card has a connector mounted thereon. An anti-vibration CPU resides on a separate, flexible printed circuit card and is connected to the anti-vibration sensors by inserting a portion of the flexible printed circuit card into the connector on the sensor card.

  • Patent number: 5521670
    Abstract: 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.
