PURPOSE:To attain a sure operation with high reliability, by holding a disc at the descending position of two plate materials provided by prescribed constitution and holding the disc in the reproducing state at the elevating position. CONSTITUTION:The 1st plate material 57 moving vertically, and the 2nd plate member 61 provided freely turnably in the direction nearly perpendicular to the lower surface of the plate material 57 and by being energized toward the plate member 57 are provided. Further, a disc holding member 35 placed on the plate material 61 with one point support a part of which is loosely fitted to the plate material 57, and a disc rotation driving means are provided. Further, the disc is held by the holding member 35 at the descending position of the two plate materials 57, 61 and the plate materials 57, 61 are elevated to the position of the rotation driving means at this holding state and this rotation driving means and the holding member 35 hold the disc at the reproducing state. |
