設けたことを特徴とする自動焦点調節装置。[Scope of Claim for Utility Model Registration] A two-part light receiving element that projects infrared light from a light projecting element onto a subject and receives the infrared light reflected by the subject through a light receiving lens provided outside the photographic lens system; 2
It is equipped with a swinging member that supports the divided light-receiving element so that it can swing freely around an axis perpendicular to the plane containing the photographing optical axis, and the swinging member is linked to the cam provided on the focus ring via an adjustment pin. In an automatic focusing device with a movable light receiving part, in which the focus ring is rotated so that both outputs of the two-split light receiving element match, the adjustment pin is allowed to be displaced in the height direction of the cam. An automatic focus adjustment device characterized in that a guide member is provided for regulating displacement of a cam in a radial direction.
