PURPOSE:To reproduce both sides of a disk by inversely moving one pickup fixed to a timing belt stretched over a pulley in a prescribed shape and to prevent laser light from radiating into a disk inserting hole by a light plate. CONSTITUTION:A carriage 50 equipped with the pickup 51 and restrained by the circular timing belt stretched in a U-shape by the inversion pulley 34 is moved in the radial direction of an optical disk. When the carriage 50 approaches the side of the inversion pulley 34, and the timing belt is further moved, the carriage 50 is guided by a guide plate 15, and is moved to the side of an opposite surface of the optical disk, so that the other side of the optical disk is reproduced by the pickup 51. The light shielding plate 19a is fixed to the inversion pulley 34 and is integrally rotated to prevent the laser light emitted from the pickup 51 from radiating through the optical disk inserting hole in a front panel to the outside in the midst of inversion of the carriage 50 guide by the guide plate 15. |
