PURPOSE: A patterning device of a light guide plate capable of individually powering upper and lower rollers is provided to rapidly perform a marking work on a wide area using an ink marking method. CONSTITUTION: A patterning device(A) of a light guide plate capable of individually powering upper and lower rollers comprises an inlet device(1), a pattern forming device(5), a drive unit(56), and an outlet device(7), and a controller. A transfer unit and a thickness measurement unit are installed on the inlet device. The thickness measurement unit measures the thickness of a light guide plate transferred through the transfer unit. A printing plate for forming patterns on the light guide plate is formed on the outer surface of the pattern forming device. The drive unit comprises first and second drive units for driving upper and lower rollers. The outlet device discharges the patterned light guide plate to the outside. The controller individually controls the first and second drive units. |
