Patent ID: 7824078

Claim:
A cover of an electronic device having an illumination device installed inside comprising: a body made of transparent material and installed in the cover and exposed to the illumination device, the body having a first surface as an inner surface and a second surface as an outer surface; and the body comprising: a first light-blocking region and a first light-passing region defined on the inner surface, with the first light-passing region encompassed by the light-blocking region, wherein the first light-passing region admits of light from the illumination device into the body through the inner surface; a second light-blocking region and a second light-passing region defined on the outer surface, with the second light-blocking region oppositely corresponding to the first light-passing region and the second light-passing region oppositely corresponding to the first light-blocking region, the second light-blocking region configured in a shape conforming that of the first light-passing region, but the shape being formed smaller than that of the first light-passing region, and which thereby permits light to further pass the body through a gap defined between the contours of the second light-blocking region and the first light-passing region, whereby light passing through the gap gives an effect that the shape of the second light-blocking region looks three-dimensional.
