ABSTRACT:
In an automatic focusing camera capable of bringing the lens into focus by automatically detecting the distance between the object and the camera, an automatic focusing device for a camera comprises an actuating member which is operated prior to the start of shutter operation, and a retainer which retains the actuating member at the initial stage of the release operation. The retainer is adapted to cancel the retention of the actuating member prior to start of the shutter operation by the shutter releasing member. The actuating member is interlocked with a coincidence type rangefinder which detects the focus of the lens and the actuating member can be returned to its initial position interlocking with the return motion of the shutter releasing member.
