Abstract

본 발명의 도광판 제조 장치는 소정 두께를 가지는 도광판용 기판을 이송시키는 이송장치; 이송되는 기판의 이동을 검출하는 검출기; 이송 장치에 의하여 이송되는 기판을 상하에서 가압하기 위하여 서로 소정 간격을 가지고 대향하여 설치되는 한 쌍의 가압 롤러; 한 쌍의 가압 롤러의 적어도 하나에 부착되고, 광 산란 패턴이 형성되어 있는 스탬퍼; 및 한 쌍의 가압 롤러 중 적어도 하나에 연결되어, 상기 가압 롤러 사이의 간격을 조정하는 간격 조정 장치로 이루어진다. 간격 조정 장치는 검출기에서 검출된 기판의 이동이 시작되는 부분에서는 상기 간격을 기판의 두께보다 크게 유지하고, 중간 부분에서는 상기 기판의 두께보다 작게 유지하고, 끝 부분에서는 상기 기판의 두께보다 크게 유지하도록 간격을 조정한다.
