Abstract
An apparatus for providing a guide and positioning mechanism for dictating retraction motion of a retractable member such as a retractable media jack. The apparatus is comprised of a "J-shaped" cam follower having a short end press-fit into a cam pushing with the longer end of the cam follower tracing out the path boundaries as dictated by a groove within a cam track. The cam bushing is comprised of a generally cylindrical cam axle through with the short end of the cam follower passes and an extended wedge-shaped extension for providing support to the extended longer portion of the cam follower. The longer portion of the cam follower is rotationally bounded by stops on each end of the wedge-shaped extension on the cam axle which keeps the long end of the cam follower radially bounded as the cam follower traces a catch and release path of the cam track during extension and retraction of the retractable member.
