Abstract
An active scraper which can form a scattering pattern on a light guide plate to a uniform depth even when the light guide plate has a curved surface, and an apparatus for manufacturing a light guide plate using the active scraper. The active scraper includes a drive-force generating part which generates drive force, and a transmitting part which transmits the drive force to teeth of a body part. The active scraper further includes the body part which converts the drive force into surface-unit drive force corresponding to the width of the body part, and a scraping part which is provided on the end of the body part. The scraping part converts the surface-unit drive force into line-unit drive force. The teeth are provided on the scraping part and form grooves of a scattering pattern in a light guide plate at a predetermined pitch.
