PURPOSE: An ultra-slim optical joystick is provided to supply user convenience by enabling the movement of a cursor through an optical pointing device and selecting or executing a command. CONSTITUTION: A bottom package includes a light source member(24), an image sensor(26) and a transparent seal material. A top package includes: a light system which transfers an infrared ray of the light source member to an object; an optical guide system(44) that transfers the infrared ray reflected from the object to the image sensor; and an external light blocking unit(46). A click switch(200) selects or executes an object indicated by a cursor or a pointer while being switched. The light guide system comprises an optical fiber of a multi-core structure. |
