効果を奏するものである。"Effects of the Invention" As is apparent from the above-described embodiments, the present invention is a tray (11) for closing the disk outlet (13) of the front panel (12) at the time of reproduction at the outer end of the tray (11) on which the disk is placed. A separate tray lid (26) is provided, and the tray lid (26) is attached to and detachable from the tray (11), and the spring (3
In 1), the tray lid (26) is elastically biased toward the tray (11), and the tray (11) enters before the position where the tray lid (26) contacts the front panel (12). The tray (11) by moving it to the playback position.
The tray lid (26) is supported slightly apart from the outer edge, and the spring (31) force increases, and the force of the spring (31) works to bring the tray lid (26) into close contact with the front panel (12). The adhesion of the tray lid (26) to the front panel (12) is high, so that the noise generated inside can be surely prevented from leaking from the disc outlet (13), and the tray lid (26) can be attached to the tray (11). ), The tray lid (26) and the front panel (12) may be closely attached to the front panel (12) due to molding and assembly errors of the tray (11) and its supporting members and the front panel (12). Even if there is a slight angle between them, the tray lid (26) absorbs that angle and properly adheres to the front panel (12) to perform its proper function and contribute to the quality improvement of the disc player. It is effective.
