description A partition wall 10 composed of a conductor for partitioning the inside of an exterior packaging case 7 into two portions is provided and at the same time, approximately the whole face of at least one face of the partition wall 10 is covered by an insulation plate 11, and a table rotation device 82 and an optical pickup device 86 are disposed in a first chamber 72 in the exterior packaging case 7 partitioned by the partition wall 10 and insulation plate 11 and at the same time, a printed circuit board 4 is disposed in a second chamber 73. In this manner, a possibility of a phenomenon that the table rotation device or the optical pickup device is affected thermally based on the heat generated caused by the operation of electronic parts or the like mounted on the printed circuit board such that a malfunction or the like occurs will be avoided.
