Claims

[Scope of utility model registration request]

(1) A distance measuring section that measures whether the subject is closer or farther than a predetermined distance and outputs distance information, and a distance measuring section that measures whether the subject is closer or farther than a predetermined distance and outputs distance information from the first position entering the optical path of the photographing lens and the optical path of the photographing lens. a close-up lens that moves between the retracted second position and a means for moving the close-up lens from one of the first and second positions to the other charging position; , means for locking the multiple rose-up lens in a charging position;
and a means for releasing the locking of the close-up lens by the locking means, and the simple autofocus is characterized in that the locking release means is controlled by the distance measurement information to adjust the focus of the photographing lens. camera.

(2) The close-up lens is moved from the second position to the first position and locked in conjunction with the film winding operation, and when the subject is far away, the close-up lens is unlocked using an electromagnet. A simple autofocus camera according to claim 1, characterized in that the camera is adapted to be returned to the second position.
