Abstract: A tray body has a disk-receiving space defined by a disk-confining wall having a bottom wall surface confining a bottom side of the disk-receiving space and a peripheral wall surface converging gradually and outwardly from the bottom wall surface thereof. The bottom wall surface of the disk-receiving space has a central portion indented to form an inner disk-receiving space and an outer disk-receiving space around the inner disk-receiving space. A recess-confining wall has a bottom wall surface confining a bottom side of the inner disk-receiving space and a peripheral wall surface converging gradually and outwardly from the bottom wall surface. The tray body is formed with a reading hole extending through portions of the bottom surfaces of the recesses adjacent to the rear end.

Abstract: A coupling device is used for securing an audio/video player such as a DVD player onto a flat panel display, thereby enhancing space utilization. The coupling device includes a chassis for receiving therein the audio/video player in an upright manner, and a hanger attached to the chassis and having a coupler structure engageable with the flat panel display for coupling the chassis to the flat panel display.
