けてなるカメラの合焦検出駆動装置。[Claims for Utility Model Registration] By performing the focus detection drive, the imaging light of the focus detection optical system is guided to the focus detection light receiving section, and the position of the photographing lens is determined by the focus detection output at this time. In a camera with a focus detection device that controls the focus point, by rotating the photographic lens in one direction around the optical axis, the photographing lens is moved in the optical axis direction and rotated in the other direction. A focus detection drive of the focus detection device is provided on a drive ring that drives the shutter to perform an exposure operation in conjunction with the movement of the photographic lens when the drive ring rotates in the one direction. A camera focus detection drive device that is integrally provided with a focusing cam section.
