    • A drive mechanism (1) of a camera apparatus includes a worm gear (4) to which a rotational driving force of a drive motor (2) is transmitted, a worm wheel (6) around which a helical gear (5) is formed to engage with the worm gear (4), and a support frame (7) which supports the worm wheel (6) rotatably and movably along a rotation axis. A rotational driving force of the worm gear (4) is transmitted to the worm wheel (6) with reduced gear ratio. An externally threaded portion (10) of a shaft portion (8) of the worm wheel (6) is engaged with an internally threaded portion in a supporting hole (14) of the support frame (7), so that the shaft portion (8) moves along the rotation axis when the worm wheel (6) rotates. Consequently, the rotational driving force transmitted to the worm wheel (6) is converted into a linear thrust force along the rotation axis. This makes it possible to provide a camera apparatus which can develop a larger thrust force and adjust an amount of travel more finely.

    • A dome camera (1) includes a lens unit (5) having an adjustable lens focal point, a dome cover (4) for covering the lens unit (5), and a pseudo-cover (7) having optically equivalent characteristics to those of the dome cover (4). The pseudo-cover (7) is capable of rotating around a rotation axis which is set at the lens unit (5) from a lens focal point adjusting position which is set on an optical axis of the lens unit (5) toward a retraction position which is back from the optical axis of the lens unit (5). At the time of lens focal point adjustment work, the lens focal point is adjusted while the pseudo-cover (7) is set at the lens focal point adjusting position. When the lens focal point adjustment work ends, the pseudo-cover (7) is rotated to the retraction position to retract from the optical axis of the lens unit (5), and the dome cover (4) is put over the lens unit (5). Thus, there is provided a dome camera capable of improving the workability of the lens focal point adjustment work with a simple and inexpensive configuration.
    • 一种半球摄像机(1)包括具有可调透镜焦点的透镜单元(5),用于覆盖透镜单元(5)的半球盖(4)和具有光学等效特性的伪盖(7) 圆顶盖(4)。 假盖(7)能够从设置在透镜单元(5)的光轴上的透镜焦点调节位置朝向缩回位置旋转围绕设置在透镜单元(5)处的旋转轴线 其从透镜单元(5)的光轴返回。 在透镜焦点调整工作时,在将伪罩(7)设置在透镜焦点调整位置时调整透镜焦点。 当透镜焦点调节工作结束时,假盖(7)旋转到缩回位置以从透镜单元(5)的光轴缩回,并且将半球盖(4)放置在透镜单元( 5)。 因此,提供了一种能够以简单且便宜的配置来改善透镜焦点调节工作的可操作性的圆顶照相机。
