摘要:
A cover is moved to an opened position or a closed position at a back side of an opening of a cabinet. A gap in which the cover can lie down is provided between an upper inner wall of the cabinet and a disk holder placed in an insertion completing position of an MD. A first guide groove and a second guide groove, in which a first guide pin and a second guide pin projected in a longitudinal direction from the cover slide, are respectively formed on cover retaining sections provided to both side surfaces of the cover. When each guide pin is guided along each guide groove, the cover draws a substantially arc-like trajectory along the inner wall of the cabinet and enter the gap from an upper end section of the cover. When the cover draws such a trajectory, an opening of a recording and reproducing apparatus into which a recording medium is inserted can be closed by the cover regardless of the case whether or not the recording medium is attached to the recording and reproducing apparatus, and the cabinet of the recording and reproducing apparatus can be small.
