<p>A disc drive in which sufficient rigidity is ensured even when a low rigidity material, e.g. an aluminium alloy or a magnesium alloy, is employed and malfunction due to deformation of the chassis enclosure can be prevented. The chassis enclosure comprises a base main body (10) and a lid body (130). A disc insertion opening (11) for inserting a disc directly is provided on the front surface of the chassis enclosure, and a connector (12) is arranged on the rear surface. A lever (100) for ejecting the disc is provided on the side part of the base main body (10), a lever (110) for regulating insertion of the disc is provided on the rear surface side, and a rear base (13) is provided at a position not overlapping a traverse (30) but covering a printed board (14). An ejecting lever sliding face (311) is formed on the rear base (13) by projecting either the lower surface of the ejecting lever (100) or the upper surface of the rear base (13). Regulation lever sliding faces (312, 313) are formed on the rear base (13) by projecting either the lower surface of the regulation lever (110) or the upper surface of the rear base (13). Openings are arranged on the rear base (13), both side parts of the ejecting lever sliding face (311) and on the both side parts of the regulation lever sliding faces (312, 313).</p> |
