Abstract
A camera focus adjustment mechanism characterized by a base assembly, a clamping assembly, and a screw mechanism coupling the base assembly to the clamping assembly. The clamping assembly includes a carriage plate and a clamping plate, where the carriage plate is coupled to the screw mechanism and the clamping plate is adjustably coupled to the carriage plate. The clamping plate firmly clamps around the barrel of a camera lens assembly, and is adjustable relative to the carriage plate in a direction substantially perpendicular to the focusing axis of the camera lens assembly. The focus of the camera lens assembly is adjusted by rotating the screw mechanism to cause the clamping assembly (and therefore the barrel of the camera lens assembly) to move in a direction parallel to the focusing axis.
Claims16
A camera focus adjustment mechanism comprising:
- base means;
- clamping means for securing a barrel of a camera lens assembly, said clamping means including a carriage plate and a clamping plate, wherein said clamping plate is arranged to secure the camera lens barrel and is adjustably coupled to said carriage plate such that said clamping plate can move in an adjustment direction substantially perpendicular to a focusing axis of said camera lens assembly;
- and
- screw means coupling said clamping means to said base means, said screw mean having an axis of rotation which is parallel to said focusing axis of said camera lens assembly, such that rotation of said screw means causes said camera lens assembly to move along said focusing axis in a direction substantially perpendicular to said adjustment direction.

- and
- screw means coupling said clamping means to said base means, said screw mean having an axis of rotation which is parallel to said focusing axis of said camera lens assembly, such that rotation of said screw means causes said camera lens assembly to move along said focusing axis in a direction substantially perpendicular to said adjustment direction.
