Patent ID: 8247736

Claim:
An apparatus for forming a pattern, the apparatus comprising: a pattern storing unit for storing data on a light guide pattern to be formed in a light guide panel; a controller for reading out the data on the light guide pattern stored in the pattern storing unit, and transmitting a position signal of each light guide pattern to be formed in the light guide panel to an X-Y driver and simultaneously, transmitting a switching signal, which is generated on the basis of length information of the light guide pattern, to a laser oscillating unit; the laser oscillating unit for outputting a laser beam synchronized with a movement of a header unit, on the basis of the position signal received from the controller; the X-Y driver for moving the header unit and a stage, on the basis of the position signal received from the controller; the header unit moving along a fixed first guide rail in the left and right direction of the light guide panel by way of the X-Y driver, and forming the light guide pattern in the light guide panel by vertically downwardly reflecting and concentrating the laser beam output from the laser oscillating unit; and the stage moving along a fixed second guide rail in the front and rear direction of the light guide panel by way of the X-Y driver, and safely mounting the light guide panel thereon, wherein the header unit comprises a beam splitter for splitting the laser beam being output from the laser oscillating unit up two or more laser beams, and an optic unit for reflecting and concentrating each of the two or more laser beams split in the beam splitter, and wherein the two or more laser beams simultaneously output from the optic unit are each concentrated to a multi focus at a distance on the whole processing surface of the light guide panel.
