送り装置。[Claims for Utility Model Registration] A head for recording and reproducing information is arranged to move forward and backward in the radial direction with respect to the rotation center of a turntable for placing a disk, and the head is moved in the radial direction of the turntable. At the same time as biasing with a spring,
A head feeding device for a disk information recording and reproducing device, in which a follower that is displaced together with the head is brought into elastic contact with the circumferential surface of a cam plate that rotates in conjunction with the turntable by the spring force of the spring, the head feeding device having a curvature. A plurality of arc-shaped guide surfaces whose radii change uniformly are formed in a step-like manner in the circumferential direction on the circumferential surface of the cam plate, and the center of curvature of each of the arc-shaped guide surfaces is set to the center of rotation of the cam plate. A head feeding device for a disk information recording/reproducing device, characterized in that the head feeding device is made to coincide with the following.
