US Patent 7290894 Indicating apparatus for electronic devices

An indicating apparatus transmits beams from an indicating lamp and includes a panel. The panel has an open area defined thereon. The open area includes a C-shaped slot and an upright slot. The C-shaped slot generally surrounds an opaque area, and the upright slot is defined in the opaque area. A center of the opaque area is generally aligned with the indicating lamp, and the opaque area has a protrusion pointing toward the indicating lamp. The preferred shape of the protrusion is either a conical or pyramidal, and reflects the beams from the indicating lamp to the open area. One exemplary application of the indicating apparatus is to indicate a “power on” status of an electronic device.
