  • Publication number: 20040042785
    Abstract: A lens shutter system has an inner drive ring which is rotated by a drive motor and an outer drive ring which is rotated by the drive motor. A plurality of shutter blades of the lens shutter system are driven through drive pins of the inner drive ring and drive pins of the outer drive ring so as to be opened and closed or are rotatably supported by the respective pins of the rings. Upon shutter opening, only the inner drive ring is driven clockwise to open the shutter blades. Upon shutter closing, only the outer drive ring is similarly driven clockwise to close the shutter blades. As mentioned above, upon switching between shutter opening mode and shutter closing mode, the direction of rotation of the inner and outer drive rings is not changed. Thus, the shutter operation can be performed at high speed.

  • Patent number: 6151451
    Abstract: This invention provides a display illuminating apparatus for use in a camera, which is operable without generating great noise and hence permits at least the AF and AE operations of the camera to be performed without the influence of noise, and which enables the operator of the camera to confirm the present operation. Information on photography by the camera is displayed on an LCD lit by an EL that is driven by an EL driving circuit. Further, a remote control switch incorporated in a switch input section of the camera sets the camera in a state in which it can receive a remote control signal. Where the camera is set in a remote control mode by the remote control switch, the operation of the EL driving circuit is stopped by an instruction from a CPU, thereby inhibiting lighting of the EL.
