摘要： A control panel cover assembly for use in an ultra-compact, jack-in-the-box, rear-projection television receiver. The receiver is housed in an open-topped cabinet having lid means pivotally attached at the back thereof for selectively opening and closing the cabinet providing for emergence and storage of an elevatable unitary optical assembly including a rear-projection screen. The unitary optical assembly includes rigid, box-like shroud means. The receiver has a widthwise-oriented control panel means located inwardly adjacent to the top section of the front panel of the receiver. The control panel cover assembly according to the invention comprises an outwardly swinging cover member which is attached to the lid at the front thereof by at least one inwardly-spring-biased hinge. The front panel of the receiver has a recess adjacent to the control panel for receiving the cover member. As the unitary optical assembly is elevated from the cabinet the lid is urged upwardly, raising the control panel cover member from the recess and uncovering the control panel. When the unitary optical assembly is lowered into the cabinet the lid is lowered and the control panel cover member swings downwardly and inwardly for re-entering the recess and covering the control panel.
