Claims

[Scope of utility model registration request]

(1) In a video camera that forms an optical image of a subject in front on a solid-state image sensor through a lens placed in a lens barrel, and converts this into an electrical signal and extracts it, the solid-state image sensor A main lens on which an optical image is formed is mounted in a cylindrical holder, and the cylindrical holder is movable in the direction of an optical axis passing through the lens barrel. The focus position of the main lens is adjusted by moving this cylindrical holder in the optical axis direction, and the solid-state image sensor is located on the rear end of the lens barrel. The solid-state imaging device is attached via a screw to a mounting flange that is detachably attached to the portion, and by adjusting the screw, the perpendicularity of the solid-state image sensor to the optical axis is adjusted.
Video camera.

(2) A spring is disposed between the solid-state image sensor and the mounting flange, whereby the solid-state image sensor is always biased in a direction away from the mounting flange. Video camera as described in section.

(3) The lens barrel has a flange on an outer circumferential surface of a substantially central portion thereof in the length direction, and the flange constitutes a part of the main body structure of the video camera. The video camera according to item 1 or 2.

(4) A frame having a cross-sectional shape surrounding the focal plane of the main lens is attached to the flange that constitutes a part of the main body structure of the video camera, and the solid body is located within the area surrounded by the frame. A utility model in which an image sensor is housed, and the frame is configured to move integrally with the mounting flange when the mounting flange is attached to or removed from the lens barrel. A video camera according to registered claim 3.

(5) The mounting flange is provided with a rotation inhibiting portion for inhibiting the rotation of the mounting flange on the lens barrel, any one of claims 1 to 4 of the utility model registration claims. Video camera described in Crab.
