본 고안은 레이저비임 프린터의 내부에 일정이상의 습기가 발생되어 내부 렌즈의 굴절율이 변화되는 것을 방지하기 위한 레이저 비임 프린터의 내부 습기 제거장치에 관한 것이다.The present invention relates to an internal moisture removing apparatus of a laser beam printer for preventing a change in the refractive index of the internal lens by generating a predetermined moisture inside the laser beam printer.
종래에는 회전 다변경에 레이저를 반사시켜 드럼에 투영시키는 레이저비임 프린터는 회전 다변경의 각 변위에 따라 드럼에 맺히는 상이 등간격으로 맺히도록 비구면렌즈가 사용되는데, 레이저 비임 프린터의 함체 내에 장기 사용이나 습윤기후등으로 인하여 습도가 높아지면 렌즈표면에 습기로 인해 이슬이 맺혀 렌즈의 굴절율이 일정하지 못하게 되므로서 드럼에 맺히는 상이 등간격으로 맺히지 못하여 화질이 선명하지 못한 문제점이 발생되었다.Conventionally, a laser beam printer reflecting a laser to a rotating beam change and projecting it onto a drum uses an aspherical lens so that the images formed on the drum are formed at equal intervals according to each displacement of the rotating beam change. If the humidity is increased due to the wet weather, dew on the lens surface due to moisture, the refractive index of the lens is not constant, so the image formed on the drum was not formed at equal intervals, the image quality is not clear.
특히 상기한 문제점은 습윤한 기후 지방에서는 더욱 심화되므로 일정이상의 습기가 레이저 비임 프린터의 함체 내에 발생되면 자동적으로 습기를 제거한후 프린터할수 있는 새로운 장치의 개발이 요구되어 왔다.In particular, the above problems are further exacerbated in wet climates, and when a certain amount of moisture is generated in the enclosure of the laser beam printer, there has been a demand for the development of a new device capable of printing after removing moisture automatically.
따라서 본고안은 상기한 문제점을 해소하고 수요자의 요구를 충족시키기 위하여 안출한 것으로서 습도감지센서를 이용하여, 일정 이상의 습기가 발생되면 경보음과 함께 내부 송풍기를 작동시켜 렌즈표면의 습기를 제거한후 프린터 할수 있는 장치를 제공하는데 목적이 있는 것으로서 이하 첨부된 도면에 따라 기술적 구성을 상세히 설명하면 다음과 같다.Therefore, this paper has been devised to solve the above problems and meet the demands of the consumer. When a certain amount of moisture is generated, the internal blower is operated together with an alarm sound to remove moisture from the lens surface. The purpose of the present invention is to provide a device that can be described in detail with reference to the accompanying drawings as follows.
광선을 투사하는 레이저다이오드(7)와 회전다변경(5)의 일직선상의 사이에 콜리메이터렌즈(6)가 형성되고, 상기 회전다변경(5)에서 광선이 반사되는 선상에 원통형렌즈(4)와 비구면렌즈(3)를 순차로 장설시켜 드럼(2)의 표면에 상을 형성시키는 레이저 비임 프린터에 있어서 상기 함체(1)내에 경보기(11)를 장설하고 상기 원통형렌즈(4)와 비구면렌즈(3) 사이의 일측에 습도감지센서(8)를 부착하며 타측에 송풍기(9)를 부착하여 회로부(10)와 각각을 접속시켜 구성된 레이저 비임 프린터의 내부 습기 제거장치이다.The collimator lens 6 is formed between the laser diode 7 projecting the light beam and the rotational change 5 in a straight line, and the cylindrical lens 4 and the cylindrical lens 4 on the line reflecting the light beam from the rotational change 5. In a laser beam printer in which an aspherical lens 3 is sequentially installed to form an image on the surface of the drum 2, an alarm 11 is installed in the housing 1, and the cylindrical lens 4 and the aspherical lens 3 are installed. The humidity sensor 8 is attached to one side between the) and the blower 9 is attached to the other side is the internal moisture removal device of the laser beam printer configured by connecting the circuit unit 10 and each.
위와 같이 구성된 본고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present proposal configured as described above are as follows.
레이저다이오드(7)에서 콜리메이터렌즈(6)를 통해 광선을 투사하면 고속회전되는 회전다변경(5)에 광선이 일정각도로 반사되고, 이때 반사된 광선이 원통렌즈(4)와 비구면렌즈(3)를 투과하여 드럼(2)에 상을 형성시켜 프린트하게 되는데, 레이저 비임 프린터 함체(1)내의 공기가 일정습도 이상의 습기를 함유하고 있을때에 습도 감지센서(8)가 이를 감지하여 경보기(11)가 작동시켜 경보음을 발생시킴과 동시에 송풍기(9)의 작동으로 렌즈표면에 응결된 이슬 또는 습기를 제거하게되고, 함체(1)내의 습도가 일정이하로 내려가면 프린트하는 것으로서 렌즈표면의 습기로 인한 광선의 산란 또는 일정하게 굴절되지 못하여 드럼에 맺히는 상의 선명도가 떨어진 상태로 프린트되는 것을 방지한 것으로 항상 선명한 화질을 제공받을 수 있는 것이다.When the laser diode 7 projects the light beam through the collimator lens 6, the light beam is reflected at a predetermined angle to the rotational change 5 which is rotated at high speed, and the reflected light beam is reflected by the cylindrical lens 4 and the aspherical lens 3 ) Is formed by printing the image on the drum (2), the humidity sensor (8) detects this when the air in the laser beam printer housing (1) contains moisture above a certain humidity and the alarm (11) Is activated to generate an alarm sound and at the same time removes dew or moisture condensed on the lens surface by the operation of the blower 9, and prints when the humidity in the enclosure 1 falls below a certain level. Because of the scattering of the light beams due to the scattering of the light beams or the irregularity of the light beams, the sharpness of the image formed on the drum is prevented from being printed.
상술한 바와 같이 본 고안은 레이저 비임 프린터 내부에 습기로 인하여 화질이 나빠지는 것을 방지하므로 언제나 선명한 화질을 얻을수 있는 매우 유익한 고안인 것이다.As described above, the present invention prevents the image quality from deteriorating due to moisture inside the laser beam printer, which is a very advantageous design that can always obtain a clear image quality.
