An electronic appliance includes an enclosure and an internal device (50). The enclosure includes a bezel (10) defining at least one opening (111). A pair of slanting slideways (151) is defined in the bezel. A bracket (20) is slidably attached to inside of the bezel to cover said opening. A pair of pivots (23) is formed on each end of the bracket, for being received in the slideways. A pair of slanting surface (211) is defined on the bracket. A pair of springs (30) connects between the bracket and the bezel. A tray (51) of the internal device is ejected out to push against the slanting surfaces of the bracket, the bracket is thereby moved to expose said opening, and the tray is extended through said opening. The springs drive the bracket to cover said opening after the tray is retracted in the internal device.
