PURPOSE:To prevent the revolution of the disc unit itself and the inconvenience due to position shift, by forming the alignment section consisting of the coupling section to regulate the relative position, at the mutual opposing section between the unit loading section and the disc unit. CONSTITUTION:The projection 27 is placed in the unit support plane 8 of the unit loading section 3 so that this projection 27 can be latched to the latch hole 28 formed under the lower surface of the lower cover 10a. Further, the disc unit alignment section 29 is constituted, which regulates the relative position between the unit loading 3 and the disc unit 2. Moreover, the alignment indication marks 30, 30 are displayed on the unit support surface 8 and the upper cover 10b corresponding to the disc unit alignment section 29. The rotation of the disc unit can be prevented and the protection of disc is ensured, allowing to perform ease of handling. |
