Abstract

본 발명은 레이저 빔 주사장치에 관한 것이다.The present invention relates to a laser beam scanning device.

이 레이저 빔 주사장치는 빔편향기(11)와 감광드럼(21) 사이의 충분한 광경로 확보와 그 크기를 감소시키기 위한 수단으로 다중 반사가 가능하도록 제1 및 제2전반사미러(23, 25)를 구비하였다. 상기 제1 및 제2전반사미러의 사잇각은 45°이고, 제1전반사미러(23)에 입사되는 빔과 제2전반사미러(25)에서 출사되는 빔은 평행한 것을 특징으로 한다.The laser beam scanning apparatus uses the first and second total reflection mirrors 23 and 25 to enable multiple reflections as a means for securing a sufficient optical path between the beam deflector 11 and the photosensitive drum 21 and reducing its size. Equipped. The angle between the first and second total reflection mirrors is 45 °, and the beam incident on the first total reflection mirror 23 and the beam exiting from the second total reflection mirror 25 are parallel to each other.
