Abstract

LED 헤드는, 발광소자 의열, 발광소자로 부터 나오는 방사광을 수신하여 인쇄용지상의 소정위치에 방사광을 모으기위한 수렴렌즈, 및 발광소자의 열로부터 소정거리만큼 떨어진 위치에 수렴렌즈를 보호지지하기위한 홀더부를 구비함과 동시에 수렴렌즈와 홀더부는 서로 일체로 형성된다. 이것에 의해, LED헤드는 방사광을 인쇄용지상의 소정위치에 정밀하게 모을 수 있다.The LED head is a holder for protecting the convergence lens at a position separated by a predetermined distance from the heat of the light emitting element, a convergence lens for receiving radiation from the light emitting element and collecting the radiation light at a predetermined position on the printing paper. At the same time, the converging lens and the holder are integrally formed with each other. As a result, the LED head can accurately collect the emitted light at a predetermined position on the printing paper.
