    • A variable focal lens which does not require a reduction of a zoom factor and eliminates an origin sensor is provided. A microcomputer 15 functions as a focus adjustment section which controls a stepper motor 13 to move a focusing ring 5 for a focus adjustment. The microcomputer 15 causes the focusing ring 5 to move by a first moving distance in a first moving direction toward one of a FAR side and a NEAR side, and then to move the focusing ring 5 by a second moving distance in a second moving direction opposite to the first moving direction, and set the point where the focusing ring reaches after the movement in the second moving direction as a reference point for adjustment, and the microcomputer 15 causes the focusing ring 5 to move from the reference point for adjustment in the first moving direction within a range equal to or less than the second moving distance to carry out the focus adjustment. This configuration eliminates margins provided by software at ends of the movement range of the focusing ring 5.
    • 提供了不需要减小缩放因子并消除原点传感器的可变焦距透镜。 微型计算机15用作焦点调节部分,其控制步进电机13移动用于聚焦调节的聚焦环5。 微型计算机15使聚焦环5沿着第一移动方向朝着FAR侧和近侧移动第一移动距离,然后使聚焦环5在相反的第二移动方向上移动第二移动距离 并且将第二移动方向上的移动后聚焦环到达的点设定为调整基准点,微型计算机15使聚焦环5从第一移动方向的基准点移动到基准点 在等于或小于第二移动距离的范围内的移动方向进行聚焦调整。 该配置消除了在聚焦环5的移动范围的端部由软件提供的边缘。

    • A bearing device is composed of a shaft, a sleeve for supporting the shaft so as to be rotatable freely and a housing having a through hole into which the sleeve is inserted. A circumferential groove that extends in a circumferential direction is formed on either one surface of an outer circumferential surface of the sleeve and an inner circumferential surface of the housing. An axial groove that extends approximately in parallel to a central axis of the sleeve is formed on either one surface of the outer circumferential surface of the sleeve and the inner circumferential surface of the housing. The outer circumferential surface of the sleeve is glued to the inner circumferential surface of the housing by adhesive that intervenes in both the circumferential groove and the axial groove.

    • There is provided a domed monitoring camera apparatus allowing reduction of a shift in focus dependent on a variation in optical path length caused by a dome cover. The domed monitoring camera apparatus (1) includes a monitoring camera (3), a dome cover (5) which covers the monitoring camera (3), and a camera controller (25). The camera controller (25) functions as an adjustment unit which, when the dome cover (5) is attached, adjusts the focus of the monitoring camera (3) with the cover attached to correct a variation in optical path length caused by the dome cover (5). The camera controller (25) adjusts the focus of the monitoring camera (3) with the cover attached according to an optical path length affecting cover parameter which represents a dome cover character relative to increase or decrease of the optical path length of the monitoring camera (3).
    • 提供了一种圆顶监视摄像机装置,其允许根据由半球罩引起的光路长度的变化减少聚焦偏移。 圆顶监视摄像机装置(1)包括监视摄像机(3),覆盖监视摄像机(3)的半球罩(5)和照相机控制器(25)。 相机控制器(25)用作调整单元,当安装半球盖(5)时,安装盖子来调节监视摄像机(3)的焦点,以校正由圆顶罩引起的光程长度的变化 (5)。 照相机控制器(25)根据影像覆盖参数的光程长度调整监视摄像机(3)的焦点,该遮盖参数表示相对于监视摄像机的光程长度的增加或减小的圆顶盖字符 3)。
