    • A projecting device comprising an array of axial element lens systems, wherein each element lens system includes a single bar lens having an axial length larger than the effective aperture and adapted to form an intermediate image of a pixel of the object plane and an erect image of a magnification of unity not vertically nor laterally inverted in such a manner that the light intensity on the image plane corresponding to said pixel is defined in the form of Gaussian distribution by the eclipse of the aperture. The element lens systems are arranged in a plane perpendicular to the optical axis so as to cause the light intensity distributions of said systems to mutually overlap in the peripheral areas thereof on the image plane, wherein each row of the systems in the array is displaced by a half pitch with respect to the neighboring row to constitute a staggered arrangement thereby achieving a uniform exposure distribution, integrated in time, in the scanning direction.

    • A projection apparatus for forming an image of original on a photosensitive material opposed to the plane of the original. The projection apparatus has a projecting system composed of a plurality of projection optical system arrays. Each individual projection optical system is composed of a first and a second lens coaxially disposed and having a relatively large length as compared with its effective lens diameter respectively. The first lens is an exit side telecentric lens whereas the second one is an incident side telecentric lens. The first lens forms an intermediate image of a portion of the original on a plane between the first and second lenses and the second lens reforms the intermediate image on the photosensitive material.
    • 一种投影装置,用于在与原稿的平面相对的感光材料上形成原稿的图像。 投影装置具有由多个投影光学系统阵列构成的投影系统。 每个单独的投影光学系统由分别与其有效透镜直径相比同轴布置并具有相对较大长度的第一和第二透镜组成。 第一透镜是出射侧远心透镜,而第二透镜是入射侧远心透镜。 第一透镜在第一和第二透镜之间的平面上形成原稿的一部分的中间图像,并且第二透镜改变感光材料上的中间图像。
