From the front end of the tray (4), a fitting shaft (41)
Sliding shafts (42) protrude outward from the rear end, respectively.
Reference numeral (41) denotes a round hole (20) formed at a free end of the front panel (2), and a sliding shaft (42) extends back and forth in the side plates (10) and (10). ) (12) fit each. When the opening of the front panel (2) is completed,
The fitting shaft (41) fitted in (2) is located below the guide groove (12). That is, when the front panel (2) is completely opened, the tray (4) is inclined with the mounting surface (40) facing upward. Further, the sliding shaft (42) is in contact with the front end of the guide groove (12), and restricts the front panel (2) from opening beyond the completed state.

The tray (4) includes a turntable (3) on which a disk D is mounted at the center of the mounting surface (40), and a chuck (5) on which the center of the disk D is held. Is provided. An opening (43) is opened on the side of the turntable (3) on the tray (4), and the pickup (30) that slides in the disk radial direction is exposed from the opening (43). A gear (21) is formed on one side of the front panel (2),
A damper (22), which meshes with the gear (21) and prevents the front panel (2) from opening suddenly, is attached to the front end of the one side plate (10) as is well known. FIG. 2A is a left side view of FIG. Under the tray (4), turntable
