2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
레이저프린트장치에서 광학수단과 감광매체 상의 거리를 항상 일정하게 유지하여 레이빔의 촛점을 감광매체상에 정확하게 결상시킴In the laser printing apparatus, the distance between the optical means and the photosensitive medium is always kept constant so that the focus of the ray beam is accurately imaged on the photosensitive medium.
3. 발명의 해결 방법의 요지3. Summary of the Solution of the Invention
드럼 상에 인쇄용지 및 감광매체가 가볍게 밀착시켜 레이저빔을 포커싱하므로서 감광매체를 인쇄용지로 전사하는 레이저프린트장치가; 편차거리를 보정하기 위한 데이타들 저장하는 보정테이블을 구비하며, 프린트데이타를 도트 형태의 제1데이타로 출력하고, 수신되는 제2데이타를 분석하여 편차거리를 계산한 후 편차거리에 대응되는 보정데이타를 보정테이블에서 억세스하여 제3데이타로 출력하는 제어부와; 제1데이타를 레이저빔으로 변환하는 레이저소스와; 레이저빔을 감광매체 상에 촛점으로 결상하는 광학수단과, 감광매체에 반사되는 이미지를 감지하여 광학수단과 감광매체 상의 거리를 검출하여 제2데이타로 발생하는 검출수단과, 광학수단에 근접 위치되고 제3데이타에 의해 구동되어 광학수단을 제어하는 액츄에이터를 구비하는 프린트헤드로 구성된다.A laser printing apparatus for transferring a photosensitive medium to a printing paper while focusing a laser beam on the drum by lightly adhering the printing paper and the photosensitive medium; A correction table for storing the data for correcting the deviation distance, and outputting the print data as dot-shaped first data, analyzing the received second data to calculate the deviation distance, and then correcting the deviation data corresponding to the deviation distance. A control unit for accessing the data from the correction table and outputting the third data; A laser source for converting the first data into a laser beam; Optical means for focusing the laser beam onto the photosensitive medium, detecting the image reflected on the photosensitive medium, detecting the distance between the optical means and the photosensitive medium, and generating the second data; And a print head having an actuator driven by the third data to control the optical means.
따라서 본 발명의 레이저프린트장치는 광학수단과 감광매체 상의 간격을 일정한 상태로 유지하여 레이점빔의 촛점이 감광매체 상에 정확하게 결상되도록 동작한다.Therefore, the laser printing apparatus of the present invention operates to maintain the distance between the optical means and the photosensitive medium in a constant state so that the focus of the ray point beam is accurately formed on the photosensitive medium.
