Claims

[Scope of utility model registration request]

(1) A video camera equipped with a mount for attaching and detaching an interchangeable lens is provided with a movable light shield between a light shielding position that covers the imaging section of the video camera and an open position that opens it, and the light shield is The lens further includes an interlocking member that is biased to move toward the open position and that is displaced when an interchangeable lens is attached to the mount of the video camera to move the light shielding member to the open position. Light blocking device for replaceable video cameras.

(2) Utility Model Registration In claim 1, the light shielding body is rotatably attached to a part of the outside of the mount of the video camera, and the interlocking member is pushed by the interchangeable lens to be linear in the axial direction. A light-shielding device for an interchangeable lens video camera consisting of an interlocking pin that is displaced symmetrically and an interlocking lever that transmits the movement of the interlocking pin to a light-shielding body. ′

(3) Utility Model Registration In claim 1, the light shielding body is rotatably attached to a part of the outside of the mount of the video camera, and the interlocking member is a member that rotates when pushed by the interchangeable lens. A light-shielding device for an interchangeable lens video camera comprising one interlocking lever and a second interlocking lever that transmits the movement of the interlocking lever to a light-shielding body.
