본 고안은 복사기 유리에 관한 것으로 자세하게는 복사원고의 하단부에 위치하는 유리를 무반사처리하여 빛의 투과율을 높임으로써 복사물의 선명도를 향상시키도록 한 것이다.The present invention relates to a copier glass, in detail, to improve the clarity of the copy by increasing the light transmittance by anti-reflective treatment of the glass located at the lower end of the copy document.

복사기는 제1도에 도시된 바와 같이 광원(1)에서 빛(L)을 발생시켜 유리(2)위에 놓인 원고면(3)에서 반사시킨 후 원고면(3)에서 반사된 빛(L')을 거울(4)(5)에서 반사시켜 드럼(6)에 전사시키고 이를 드럼(6)에서 복사지에 복사시킴으로써 복사물을 얻어내고 있다.The copier generates light L from the light source 1 and reflects it on the original surface 3 placed on the glass 2, as shown in FIG. 1, and then the light L 'reflected on the original surface 3. Is reflected on the mirrors 4 and 5, transferred to the drum 6, and copied from the drum 6 to the copy paper to obtain a copy.

그러나 광원(1)에서 발생된 빛(L)은 제2도에 도시된 바와 같이 유리(2)의 표면반사로 인하여 일정량의 빛(L1)L2)이 원고면(3)에 입사되지 못하게 된다.However, in the light L generated from the light source 1, as shown in FIG. 2, a certain amount of light L1 L2 is prevented from entering the original surface 3 due to the surface reflection of the glass 2.

이는 두께를 갖는 유리(2)가 갖고 있는 표면반사 현상에 의하여 발생되는 문제점으로 통상 공기중에서의 유리(2)의 반사율(E)은 광학공식에 의거으로 얻어지게 된다(Y는 굴절률).This is a problem caused by the surface reflection phenomenon of the glass 2 having a thickness. In general, the reflectance E of the glass 2 in air is based on an optical formula. (Y is the refractive index).

따라서 유리(2)의 굴절률(Y)이 1.52이므로 반사율(R)은가 되고 이를 %환산하면 0.0425×100=4.25%가 된다.Therefore, since the refractive index (Y) of the glass (2) is 1.52, the reflectance (R) is % Converted to 0.0425 × 100 = 4.25%.

즉 유리(2)의 표면반사 현상으로 인하여 광원(1)에서 발생된 빛 중 4.25%가 원고면(3)에 입사되지 못하게 되고 유리(2)의 양측 표면에서 모두 표면반사가 나타나므로 결국 8.5%의 빛이 소멸되어지는 것이다.That is, 4.25% of the light generated by the light source 1 is prevented from entering the original surface 3 due to the surface reflection phenomenon of the glass 2, and surface reflection occurs on both surfaces of the glass 2, thus eventually 8.5%. The light of God will be extinguished.

그러므로 원고면(3)의 글씨(3')에서 반사된 빛을 8.5% 만큼 정확히 인식할수 없어 복사물의 선명도가 떨어지게 되는 것이다.Therefore, the light reflected from the letter 3 'of the original surface 3 cannot be recognized exactly as much as 8.5%, which reduces the clarity of the copy.

그리고 유리(2)의 표면에서 반사된 빛(L1)(L2)은 복사기 불필요하게 되나 원고면(3)에서 반사된 빛(L1)과 함께 드럼(6)에 입사되므로 복사물의 선명도가 떨어진다.And the light L1 (L2) reflected from the surface of the glass 2 becomes unnecessary the copier, but is incident on the drum 6 together with the light L1 reflected from the original surface 3, so the clarity of the copy is inferior.

즉 원고면(3)에서 반사된 빛(L1)만 드럼(6)에 인가되어야 하나 유리(2)의 표면에서 반사된 빛(L1)(L2)이 미약하나마 빛(L')의 주변에 영향을 미치게 되어 복사물이 선명하게 나올 수 없었다.That is, only the light L1 reflected from the original surface 3 should be applied to the drum 6, but the light L1 and L2 reflected from the surface of the glass 2 are weak but affect the periphery of the light L '. The copy could not come out clearly.

본 고안은 상기와 같은 점을 감안하여 무반사 처리된 유리를 사용하므로써 복사기 유리의 표면에서 허실되는 빛을 없애주어 선명한 복사물을 얻을 수 있도록 한 것이다.The present invention by using the anti-reflective glass in view of the above point is to eliminate the lost light from the surface of the copier glass to obtain a clear copy.

이러한 본 고안은 유리의 표면에 굴절률이 서로 다른 매질을 순차코팅시켜 무반사처리된 유리를 얻고 이를 복사기 유리로 사용하므로써 소망의 효과를 얻을 수 있게 된다.The present invention can obtain a desired effect by sequentially coating a medium having a different refractive index on the surface of the glass to obtain an antireflective glass and use it as a copier glass.

이하 본 고안을 첨부도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 고안의 복사기 유리로써 사용되는 무반사 처리된 유리의 일실시예 단면도로써3 is a cross-sectional view of an embodiment of the antireflective glass used as the copier glass of the present invention.

BK-7이라 불리는 유리(10)의 표면에 Al2O3인 산화알루미늄(11)(11'), ZrO2인 산화지르코늄(12)(12'), MgF2인 불화마그네슘(13)(13')을 순차적으로 코팅처리한 것으로 유리(10)의 표면에 굴절률이 각기 상이한 산화알루미늄(11)(11'), 산화지르코늄(12)(12'), 불화마그네슘(13)(13')을 코팅처리하므로써 투과되는 빛의 손실이 거의 없도록 한 것이다.On the surface of the glass 10 called BK-7, Al 2 O 3 phosphorus aluminum (11) (11 '), ZrO 2 phosphorus zirconium oxide (12) (12'), MgF 2 phosphorus magnesium fluoride (13) (13 ') Is sequentially coated to the surface of the glass 10, aluminum (11) (11'), zirconium oxide (12) (12 '), magnesium fluoride (13) (13'), each having a different refractive index. By coating, there is little loss of transmitted light.

무반사 처리된 유리는 상기 실시예로 제시된 물질 이외에 다른물질을 다층코팅하여 얻어낼 수 있으며 이는 코팅물의 개수가 많은 만큼 상당히 많은 경우의 수가 존재한다.The antireflective glass can be obtained by multilayer coating other materials in addition to the materials shown in the above examples, and there are a considerable number of cases as the number of coatings is large.

굴절률이 상이한 어떠한 물질을 양측면에 코팅하더라도 표면반사가 거의 일어나지 않도록 무반사 처리된 유리(10)를 복사기 유리로 사용할 경우 기존과 같이 유리(10)의 표면에서 표면반사가 일어나지 않고 입사된 빛을 그대로 투과시킴으로써 복사물의 선명도를 높일 수 있게 된다.When the antireflective glass 10 is used as a copier glass so that surface reflection hardly occurs even if any material having a different refractive index is coated on both sides, the incident light is transmitted as it is without surface reflection on the surface of the glass 10 as before. By doing so, the sharpness of the copy can be increased.

즉 제4도에 도시된 바와 같이 광원(1)에서 발생된 빛(L)이 유리(10)를 통하여 원고면(3)에서 반사된 후 거울(4)로 입사되어 지게될 때 유리(10)의 표면에서 표면반사가 일어나지 않아 원고면(3)에서 반사된 빛(L')과 광원(1)에서 발생된 빛(L)이 거의 같게 된다.That is, as shown in FIG. 4, when the light L generated from the light source 1 is reflected from the original surface 3 through the glass 10 and then enters the mirror 4, the glass 10 is turned on. Surface reflection does not occur on the surface of the light L 'reflected from the original surface 3 and the light L generated by the light source 1 are substantially the same.

따라서 유리(10)에서 손실되는 빛이 없어져 복사물의 선명도를 기대할 수 있게 된다.Therefore, the light lost from the glass 10 is eliminated can be expected the sharpness of the copy.
