<p>A relay gear, a second gear, rotation rollers, and a first gear interlocking with a driving motor are arranged on a first base, and a DVD disk is carried by these rotation rollers and fixed rollers supported by a second base. An arm contacts with an outer circumferential edge of the DVD disk thus carried and is forced rearward. This operation causes a cam arm to move a slider using a cam groove coupling portion of the slider. After positioning the DVD disk, any one of rack gears is engaged with the first gear, whereby the driving motor drives one rotation roller, one fixed roller, and the arm to be separated from the outer circumferential edge of the DVD disk.</p> |
