<p>The present invention relates to an apparatus for forming a light guide plate pattern which forms a pattern on a Light Guide Plate (LGP) of each of a Liquid Crystal Display (LCD), a keypad, a telephone, a surface light source for lighting, etc. The apparatus comprises: a rotary head portion which rotates around one side and can project a laser beam, simultaneously; and a plurality of loading portions for sliding the LGP in a radial direction with respect to a center of rotation of the rotary head portion so that the rotary head portion rotates and sequentially projects the laser beam on the LGP to form the pattern. The apparatus reduces a facility cost by using only a laser oscillation unit, tunes, maintains, and easily mends the laser oscillation unit, secures reliability of operations and accuracy and reproducibility of the pattern through a stable rotary motion, and remarkably reduces the processing time of the pattern.</p> |
