Abstract:
The lens adjustment mechanism according to one embodiment of the present disclosure is provided with: a base section; a lens holding section that holds a lens having the optical axis in the Z axis direction; an intermediate member disposed between the base section and the lens holding section; a first rotating cam, which is disposed between the base section and the intermediate member, and which moves the lens holding section in the Y axis direction by rotating about an area close to the optical axis of the lens; and a second rotating cam, which is disposed between the intermediate member and the lens holding section, and which moves the lens holding section in the X axis direction by rotating about an area close to the optical axis of the lens. The intermediate member moves in the Y axis direction with the lens holding section when the first rotating cam rotates, and when the second rotating cam rotates, the intermediate member limits the movement of the lens holding section in the Y axis direction.
