Abstract: A camera unit for an electronic conference is adapted to be set on a monitor, and comprises a stationary support base set on the monitor, a camera unit body provided on said stationary support base so as to be horizontally rotatable, a lens block supported to the camera unit body so as to be vertically rotatable, and a control device incorporated in the camera unit body, for controlling the rotation of the camera unit body and the lens block and the focal distance and zooming ratio of the lens block, the lens block is adapted to be turned between a horizontal position at which the lens block is stored in a recess formed in the camera unit body, and picks up a person in front thereof, and a vertical position at which the lens block is projected forward from the camera unit body so as to pick up a document set therebelow, and the control device controls the focal distance and zooming ratio of the lens block in accordance with a horizontally rotating position of the camera unit body and a vertical rotating posit

Abstract: A liquid-level gauge includes an indicator for indicating an amount of fuel corresponding to a liquid level of the fuel detected by a liquid level detector mounted within a fuel tank of a vehicle. The indicator used is of the leaving pointer type in which a pointer keeps pointing a value immediately before a power supply is shut off. The energization of the indicator continues for a given time enough to complete the pointing operation when a power source switch has been turned on and then is interrupted intermittently.
