has a magnetic disk disk, a first opening in the center of a side surface that houses the magnetic disk disk and is perpendicular to the surface of the magnetic disk into which the magnetic head can enter, and a second opening into which a bushing rod can enter into the end surface of the side surface. A substantially square case having an opening, a quadrant arc-shaped guide disposed between the corner of the case where the second opening is located, and the magnetic disk disk, and a sliding guide on the guide. a runner made of a flexible band-like member whose one end reaches the first opening and has an engaging portion at the other end, and a spring that biases the runner along the guide toward the first opening. When the case is attached to the magnetic disk device, the bushing rod provided on the magnetic disk device enters the case through the second opening, engages with the engaging portion of the runner, and forces the runner against the spring. The first opening is opened by pushing the runner in and retracting one end of the runner from the first opening.
以下本考案による一実施例る図面を参照して説明する。Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
