该装置特点是:将具有摄影芯片的电路板设于一机壳内,该机壳前端设有一聚焦镜头,机壳内设有一定位构件以限制电路板旋转,机壳背侧设有一伸缩元件,该伸缩元件可控制机壳内的电路板前进或后退,从而调整摄影芯片与聚焦镜头的距离,由此可使摄影机以同一构造透用不同规格的聚焦镜头,并可获一微调功能,以使摄影机的焦距调整
The device is characterized in that a circuit board with a photographing chip is arranged in a casing, a focusing lens is arranged at the front end of the casing, a positioning component is arranged in the casing to limit the rotation of the circuit board, a telescopic element is arranged at the back of the casing, The telescopic element can control the circuit board in the housing to advance or retract so as to adjust the distance between the photographing chip and the focus lens, thereby allowing the camera to use different specifications of the focus lens in the same configuration and obtaining a fine tuning function Camera focal length adjustment
