Claims (8)
- 광원과; 상기 광원으로부터 출사된 복수의 광선을 편향시키는 폴리곤 미러와; 상기 폴리곤 미러에서 편향된 각각의 광선을 복수의 감광드럼면 상에 결상시키는 결상 광학계를; 구비하는 광주사 장치에 있어서,상기 결상 광학계는 상기 폴리곤 미러와 상기 감광드럼 사이에 배치되어 상기 폴리곤 미러에서 편향된 광선이 상기 감광드럼면 상에 스폿을 형성하도록 하는 주사렌즈를 포함하고, 상기 주사렌즈의 중심축은 상기 광원의 중심으로부터 연장된 광축과 소정 간격 이격된 것을 특징으로 하는 광주사 장치.
- 제 1 항에 있어서,상기 광축과 상기 폴리곤 미러 상에서의 광선 사이의 이격거리 A1, 상기 광축과 상기 주사렌즈의 중심축 사이의 이격거리 B1 및 상기 광축과 상기 감광드럼 면 상에서의 광선 사이의 이격거리 C1 의 관계가 0.2 ≤|C1/A1|≤ 3.5 및 0.2 ≤ |B1/A1|≤ 3.5 을 만족하는 것을 특징으로 하는 광주사 장치.
- 제 1 항에 있어서,상기 광원으로부터 출사된 복수의 광선은 상기 폴리곤 미러에 부주사 방향으로 소정 각도로 비스듬하게 입사되는 것을 특징으로 하는 광주사 장치.
- 제 1 항에 있어서,상기 광원으로부터 출사된 복수의 광선은 하나의 상기 폴리곤 미러에 입사되는 것을 특징으로 하는 광주사 장치.
- 제 1 항에 있어서,상기 광원으로부터 출사된 광선을 평행 또는 수렴시키는 콜리메이팅 렌즈와, 상기 콜리메이팅 렌즈를 통과한 광선을 부주사 방향으로 수렴하여 상기 폴리곤 미러에 입사시키는 실린드리컬 렌즈를 더 구비하는 것을 특징으로 하는 광주사 장치.
- 제 5 항에 있어서,상기 광원으로부터 출사된 복수의 광선은 하나의 상기 콜리메이팅 렌즈와 하나의 상기 실린드리컬 렌즈를 통하여 상기 폴리곤 미러에 입사되는 것을 특징으로 하는 광주사 장치.
- 제 1 항에 있어서,상기 폴리곤 미러와 상기 주사렌즈 사이에 설치되어 상기 폴리곤 미러에서편향된 복수의 광선간의 간격을 변경시키는 반사 미러를 더 구비하는 것을 특징으로 하는 광주사 장치.
- 제 1 항에 있어서,상기 주사렌즈는 비대칭 비구면 플라스틱 렌즈인 것을 특징으로 하는 광주사 장치.
