Title: BACK FOCUS ADJUSTMENT MECHANISM AND VIDEO CAMERA PROVIDED WITH SAME
Abstract:
A back focus adjustment mechanism and a video camera provided with the same. The back focus adjustment mechanism comprises a driving device (10) and a positioning and guiding device (20) that are separated disposed. The positioning and guiding device (20) comprises a positioning assembly (21) and a guiding assembly (22). The guiding assembly (22) is mounted on the positioning assembly (21). The driving device (10) is in driving connection with the guiding assembly (22) to drive the guiding assembly (22) to move. In the back focus adjustment mechanism and the video camera provided with the same, after the driving device (10) and the positioning and guiding device (20) are separately disposed, the structures of the back focus adjustment mechanism can be simpler, and the reliability of the structures in the back focus adjustment mechanism is improved in the same processing precision.
