Abstract
Description
그리고, 상기 커팅롤러(1)의 구성에 있어서, 양단부의 중심에 회전축(2a)이 돌출형성되며 외주연일측에 기어부(2b)가 설치된 원통형 몸체(2)와 상기 몸체(2)의 외주연을 감싸도록 설치되는 박판커터(3)로 이루어지고, 상기 박판커터(3)의 중앙에는 형상커팅날부(3a)가 일정간격으로 돌출형성되며 상기 형상커팅날부(3a)의 양측방에는 홀커팅날부(3b)가 일정간격으로 돌출형성되는 구성은 종래의 백라이트유니트용 광학시트 커팅장치에 장착되는 커팅롤러의 구성과 동일하다.
Claims (1)
- ( 정 정 ) 공지의 광학시트 커팅장치(10)에 지지롤러(5)가 설치되며, 상기 지지롤러(5)와 한 조를 이루어 회전하는 커팅롤러(1)가 설치되고,상기 커팅롤러(1)는 양단부의 중심에 회전축(2a)이 돌출형성되며 외주연일측에 기어부(2b)가 설치된 원통형 몸체(2)와, 몸체(2)의 외주연을 감싸도록 설치되는 박판커터(3)로 이루어지고, 상기 박판커터(3)의 중앙에는 형상커팅날부(3a)가 일정간격으로 돌출형성되며 상기 형상커팅날부(3a)의 양측방에는 홀커팅날부(3b)가 일정간격으로 돌출 형성되어 있는 것에 있어서,상기 커팅롤러(1)의 몸체(2)외주연에 설치되는 박판커터(3)의 홀커팅날부(3b)일측에는 V자형 절개홈(4)이 형성되어 있는 것을 특징으로 하는 백라이트유니트용 광학시트 커팅장치의 커팅롤러.
