PATTERN TREATING DEVICE OF A LIGHT GUIDE PLATE WITH A GAP REGULATING DEVICE, CAPABLE OF ACTIVELY RESPONDING TO VARIATIONS ON THE THICKNESS OF A LIGHT GUIDING PLATE

摘要

PURPOSE: A pattern treating device of a light guide plate with a gap regulating device is provided to respectively control left and right gaps of a pattern forming roller, thereby correcting the uneven thickness deviation of a light guide plate.;CONSTITUTION: A pattern treating device of a light guide plate with a gap regulating device comprises an inserting device(1), a pattern forming device(5), a pulling device, a gap regulating device, and a controlling unit. The inserting device comprises a transferring member transferring the light guiding plate and a thickness measuring member. The thickness measuring member measures the thickness of the light guiding plate being inserted by the transferring member. A projecting plate forming patterns on a surface of the light guiding plate is mounted on the exterior of the pattern forming device and upper and lower pattern forming rollers, a heating member, and a driving member. The pulling device discharges the light guiding plate in which the patterns are formed from the pattern forming device. The gap regulating member regulates a gap of the upper and lower pattern forming rollers. The controlling unit controls the gap regulating member in order to respectively control left and right gaps of the upper and lower pattern forming rollers based on the thickness measured by the thickness measuring unit.;COPYRIGHT KIPO 2013
