Claims (6)
- 복수의 빔을 화상기록 매체 상에 소정의 피치간격으로 병행주사하는 광주사장치로서:직선상에 등간격으로 배열된 복수의 발광소자를 각각 포함하는 2개의 반도체 레이저 광원;빔 주사수단;빔 수렴수단; 및각각의 상기 반도체 레이저 광원의 빔주사방향에 대한 복수의 발광소자의 경사각을 빔 주사 중에 항상 제어하는 제어수단을 포함하는 것을 특징으로 하는 광주사장치.
- 제 1항에 있어서, 상기 각 광원의 출사빔이 빔 주사개시단 부근에 설치된 광검출기를 통과하는 순간들 사이의 시간간격의 차이를 검출하여, 각각의 상기 광원의 경사각을 조정하는 또 다른 제어수단을 더 포함하는 것을 특징으로 하는 광주사장치.
- 제 1항에 있어서, 각각의 상기 광원의 출사빔의 주사방향과 직교방향의 위치를, 빔 주사중에도 항상 검출하고, 각각의 상기 광원의 상대적인 위치변동에 기인하는 주사선의 소정의 피치간격을 제어하는 제어수단을 더 포함하는 것을 특징으로 하는 광주사장치.
- 복수의 빔을 화상기록 매체상에 소정의 피치간격으로 병행주사하는 광주사장치로서:직선상에 등간격으로 배열된 복수의 발광소자를 각각 포함하는 2개의 반도체 레이저 광원;빔 주사수단;빔 수렴수단; 및각각의 상기 광원의 출사빔의 주사방향과 직교방향의 위치 및 각각의 상기 광원의 빔 주사방향에 대한 상기 복수의 발광소자의 어레이 방향의 경사각을, 빔 주사 중에 항상 제어하는 제어수단을 포함하는 것을 특징으로 하는 광주사장치.
- 직선상 또는 평면상에 소정의 간격으로 배열된 복수의 광원;상기 복수의 광원으로부터 출사된 복수의 광빔을 기록매체상에 병행주사하는 빔주사수단;빔 주사개시단 근처에 설치된 광검출기;상기 복수의 광빔 중 2개 이상이 상기 광검출기를 각각 통과하는 순간들 사이의 시간간격을 검출하여, 검출된 시간간격과 기준시간간격의 차이를 구하는 수단; 및상기 기록매체상에서의 복수의 주사빔의 주사위치들간의 간격이 항상 소정의 값이 되도록, 상기 구해진 차이에 따라, 상기 광원의 위치를 제어하는 제어수단을 포함하는 것을 특징으로 하는 빔주사장치.
- 제 5항에 있어서, 상기 제어수단은 주사면에서의 빔 주사방향에 대하여, 복수 광원의 어레이 방향을 회전시키도록 되어 있는 것을 특징으로 하는 빔주사장치.
