  • Patent number: 7331834
    Abstract: An outboard motor is provided with a bar handle equipped with a throttle grip enabling push-pull operation and rotate operation by the boat operator, and one or the other of the engine and the motor is connected to the propeller in accordance with the push-pull operation of the throttle grip. Owing to this configuration, switching between the power sources can be performed using the throttle grip of the bar handle. In addition, the engine speed and motor speed are regulated in accordance with the rotating operation of the throttle grip, thereby avoiding degradation of operability and increase in outboard motor size.

  • Publication number: 20060127073
    Abstract: The optical apparatus of the present invention comprises: a body; a lens barrel provided in the body; a camera shake compensation mechanism that swings the lens barrel about two different rotation axes; and a connection portion for connecting the body and the lens barrel which connection portion is partly fixed to the lens barrel and disposed along the point of intersection of the two rotation axes of the lens barrel or an area formed in the vicinity thereof. By this, the amount of flection of the connection portion can be reduced so that the space for absorbing the flection can be extremely small, and further, the stress imposed on the connection portion can be made extremely small. Consequently, an optical apparatus having a small-size and highly reliable camera shake compensation mechanism is obtained.

  • Publication number: 20050281552
    Abstract: A camera has a lens barrier which can move between a closed position where a taking lens is covered and an opened position where the taking lens is exposed, and the on/off state of a power source is switched interlockingly with the open/close state of the lens barrier. A housing for housing the camera has a barrier driving lever for driving the lens barrier. At the time of attaching the housing, the tip of the barrier driving lever is retained by a finger retaining part of the camera to move the lens barrier to the opened position. As a result, attachment of the housing in a power-off state made by the lens barrier can be prevented.
