Claims

[Scope of Claim for Utility Model Registration] (1) In a mechanism for adjusting the position of a lens mount to which a lens barrel is attached relative to the imaging surface of an imaging camera, (a) a cylindrical structure with a hollow part in the center in the direction of the optical axis; (b) a mount attachment part that protrudes from the front surface of the main body frame of the imaging camera and has a hollow part in the optical axis direction in the center; (c) on the front surface of the main body frame of the imaging camera;
a holding part provided to face a part of the outer circumferential surface of the mount attachment part with a distance that allows the lens mount to fit into the mount attachment part, the hollow part of the lens mount; 1. A lens mount position adjustment mechanism for an imaging camera, characterized in that the lens mount is movably fitted to the outer circumferential surface of a mount attachment part in the optical axis direction, and the lens mount can be fixed by the holding part. (2) Utility Model Registration Claims Paragraph 1 is characterized in that the hollow part of the lens mount is a female thread, and the outer peripheral surface of the mount attachment part is a male thread that connects with the female thread. A lens mount position adjustment mechanism for an imaging camera. (3) Scope of claims for utility model registration, paragraph 1 or 2
In the device described in 1., the holding portion includes a protrusion from the front surface of the body frame of the imaging camera and a set screw attached to the protrusion, and the tip of the set screw touches the cylindrical outer circumferential surface of the mount. A lens mount position adjustment mechanism for an imaging camera, characterized in that it is configured to be able to be held down. (4) Scope of claims for utility model registration, paragraphs 1 to 3
In the imaging device according to any one of the above items, the length of the lens mount is the sum of the protruding length of the lens mount attachment portion and the length of the lens barrel end face inserted into the lens mount. Camera lens mount position adjustment mechanism.
