のレンズ繰出し機構。[Claims for Utility Model Registration] The lens block is rotated and moved in the direction of the optical axis in conjunction with the camera's relay movement, and in the middle of this movement, the movement is stopped by a goldfish signal from the automatic focus control device. In the camera configured to allow the camera to rotate, the camera includes: a feeding ring having a plurality of feeding cam portions formed with slopes in the direction of the optical axis; and a compression torsion coil spring having both compression and torsion characteristics, one end of which is fixed to the camera body. are arranged to sandwich the lens block in the optical axis direction, and the lens block is formed with a plurality of protrusions that abut the plurality of cam portions and engage with the other end of the spring. A lens extending mechanism for an autofocus camera, characterized in that an engaging portion is formed, and the spring allows the lens block to operate in a rotational direction and an axial direction.
