摘要: There are provided an optical pointing device and a personal portable employing the same, in which horizontal path is formed, thereby minimizing thickness of system providing sufficient depth focus. The includes cover glass directly contacting object, light source unit emitting to glass, receiving reflecting reflected by object predetermined direction via condensing direction, picking up image light. According present invention, possible using surface finger formed such that minimized, focus provided, keeping beautiful exterior ultra slim performing convenient pointing.
