Abstract

조명광원에 의해 촬상대상면을 광얼룩없이 균일하게 조명할 수 있음과 동시에, 조명광원으로부터의 정반사광이 화상취입수단의 수광면으로 들어가지 않도록 할 수 있으며, 또 취급성이 용이하여 소형화를 꾀할 수 있는 조명광원불이 화사취입장치를 제공한다.The illumination light source makes it possible to uniformly illuminate the imaging target surface without light spots and prevent the specular reflection light from the illumination light source from entering the light receiving surface of the image taking means. The illumination light source can provide a blower apparatus.

촬상대상면(2)을 반사갓(34), (34°)을 가지는 두 개의 조명광원(27),(27′)에 의해 각각의 우측만, 및 좌측만을 실질적으로 조명하고, 반사갓(34),(34′)을 타원 단면 및 포물선 단면을 가지는 형상으로 함과 동시에, 상기 조명광원(27),(27′)에 직접광 차단수단(38),(38)을 마련한다. 수광면(5)을 가지는 화상취입장치(25) 및 조명광원(27),(27′)의 위치 및 자세를 원고대(24)에 대해서 조절할 수 있게 한다.The imaging target surface 2 is substantially illuminated by the two illumination light sources 27 and 27 'having the reflection shades 34 and 34 °, respectively, only the right side and the left side only, and the reflection shade 34, 34 'is formed into an elliptical cross section and a parabolic cross section, and direct light blocking means 38 and 38 are provided in the illumination light sources 27 and 27'. The position and attitude of the image taking device 25 having the light receiving surface 5 and the illumination light sources 27 and 27 'can be adjusted with respect to the document glass 24.
