OPTICAL POINTING APPARATUS AND PORTABLE ELECTRONIC DEVICE COMPRISING SAME
First Claim
1. A pointing device, comprising:
- a detector for detecting movement of an object;
a housing including a housing body covering the detector and a light emitting zone provided in the housing body to allow visible light to be transmitted therethrough;
a light source emitting illumination light containing visible light to illuminate the light emitting zone; and
a light guide for changing a light path of the illumination light emitted from the light source so that the illumination light exits from the light emitting zone to an outside of the housing.

26. A light guide of a pointing device including a housing having a light emitting zone to implement decorative illumination on a circumference of a cover, a detector for detecting movement of an object, and a light source for illuminating the light emitting zone, the light guide comprising:
-
a guide body accommodated within the housing; and an illumination guide provided on the guide body to disperse illumination light emitted from the light source such that the illumination light is widely spread in the light emitting zone and exits to an outside of the housing. - View Dependent Claims (27, 28, 29, 30, 31)

32. A method of manufacturing a housing of a pointing device comprising:
-
(a) manufacturing a housing body including a cover having an infrared band pass filter type object detection zone and a visible light transmitting portion allowing visible light to be transmitted therethrough to form a light emitting zone; (b) forming a surface coating layer on a circumference of the housing body to prevent leakage of illumination light, with a mask formed on a surface of the housing body to cover the light emitting zone and the object detection zone; and (c) forming a UV resin coating layer by coating the light emitting zone and the object detection zone with a UV resin after removing the mask. - View Dependent Claims (33, 34, 35)
