連結構造。 A movable lens barrel with an electrically controlled shutter and/or aperture mechanism and a camera body that fixes a fixed lens barrel into which the movable lens barrel is slidably fitted have elasticity and flexibility. In a camera that is electrically connected by a film-like printed circuit board having a camera body, a viewfinder portion disposed in a part of the camera body outside the photographing optical path in a circumferential direction centered on the photographing optical axis and the camera body. from the inner rear end of the camera body toward the movable lens barrel side by providing a certain space between the camera body and the inner end of the viewfinder part in order to block stray light that enters from the gap created between the camera body and the inner end of the viewfinder part. An extended light shielding part and an inverted U-shaped folded part are formed in the middle part, and one end part is attached to the movable lens barrel.
The printed wiring board, the other end of which is fixed to the camera body, and the printed wiring board that is housed in the space when the upper plate movable lens barrel is retracted into the camera body, and the fixed lens barrel. The movable lens barrel extends from the movable lens barrel toward the light shielding portion in a direction along the photographing optical axis inside the folded portion in order to block stray light incident from a gap generated between the movable lens barrel and the movable lens barrel. A connection structure between a movable lens barrel and a camera body, characterized by comprising a plate-shaped push-in part.
