Abstract

The invention provides a back focus adjustment mechanism and a video camera with the same. The back focus adjustment mechanism includes a separate drive device and a positioning guide device, wherein the positioning guide device includes a positioning assembly and a guide assembly, the guide assembly is installed on the positioning assembly, and the drive device is drivingly connected to the guide assembly to drive the guide assembly to move. In the back focus adjustment mechanism of the present invention and the video camera with it, after the driving device and the positioning guide device are separately arranged, the various structures of the back focus adjustment mechanism in the present invention can be made simpler, and the back focus is increased under the same processing accuracy. Adjust the reliability of each structure in the mechanism.

Description

technical field [0001] The present invention relates to the technical field of focus adjustment devices, in particular to a back focus adjustment mechanism and a camera with the same. Background technique [0002] At present, the Z-axis of the back focus adjustment mechanism relies on screw positioning. In the existing back focus adjustment mechanism, the driving and positioning of the back focus adjustment mechanism are integrated. In this way, the precision of the parts is too high, or the back focus adjustment mechanism Z-axis coaxial accuracy is reduced. Contents of the invention [0003] The main purpose of the present invention is to provide a back focus adjustment mechanism and a video camera having the same, so as to solve the problem of high precision requirements of parts in the back focus adjustment mechanism in the prior art. [0004] In order to achieve the above object, according to one aspect of the present invention, a back focus adjustment mechanism is pr...
