ようとするものである。The present invention moves the lens system in parallel in the direction of the finder in conjunction with the movement of the lens system by a distance of 11Hj1 adjusted by an automatic focusing device to match the viewfinder's field of view and the shooting range. This is an attempt to correct parallax.

る様になっている。(5) is a behind shutter installed on the camera body (
6) is an aperture device, and (7) is a helicoid, which is provided on each of the lens barrel (3) and the movable support frame (8), and when the lens barrel (5) rotates, the halberd barrel moves back and forth. The distance can be adjusted by going in and out.
又可動支持枠（８）はカメラ本体側の枠支へ４Ｐ（９）
で支へられ鏡胴がファインダ一方向に移動し得る様に可
動支持枠（８）が滑動し得る様にしである。Also, the movable support frame (8) is attached to the frame support on the camera body side with 4 points (9).
The movable support frame (8) is designed to be slidable so that the lens barrel supported by the viewfinder can be moved in one direction.

向からバネ（１２）で押す様にしである。Also, (10) is a cam attached to the lens barrel, which is in contact with the cam holder (11) provided on the camera body.In order to ensure this contact, the movable support frame (8) is attached to the viewfinder. It is so that it is pushed by a spring (12) from the direction.
（１３）はフィルム面で撮影時には光軸の方向は鎖線Ａ

端に達する。(13) is the film plane, and when shooting, the direction of the optical axis is the chain line A
In the shooting range, the light rays indicated by dotted lines B and C reach the upper and lower ends of the film surface.
此の場合ファインダーの光軸とレンズ系の光軸は必ずし
も平行でなくてもよいが図面では平行の場合を示してい
て無限遠の被写体に対する撮影時のカメラの状態を示す
ものである。In this case, the optical axis of the finder and the optical axis of the lens system do not necessarily have to be parallel, but the drawing shows a case where they are parallel, and shows the state of the camera when photographing an object at infinity.
第二図はこの第一図に対し近距離の被写体を（３） 撮影する時のカメラの状態を示すものである。The second figure shows a subject at a closer distance (3) compared to the first figure. This shows the state of the camera when taking pictures.
