    • The present invention aims at providing an image reading device and an image forming apparatus including a light guiding body having a first emission surface and a second emission surface. A color copy machine includes a luminescence portion including: LEDs composed of a plurality of dot-shaped luminescence members disposed at predetermined intervals in a main scanning direction and/or an elongated luminescence member that is formed to extend in the main scanning direction; and a light guiding body that is disposed between the LEDs and an original, and has a light incidence portion disposed on a side to the LEDs and an emission portion disposed on a side to the original. The emission portion has a first emission surface and a second emission surface that is formed on a different plane from a plane including the first emission surface.

    • An image reading apparatus for generating image data corresponding to a document image, includes: an irradiating section for irradiating light rays to an image bearing surface of a document; a housing formed with a slit for restrictedly passing light rays reflected from the image bearing surface of the document; a photoelectric conversion element for converting an optical image made of the light rays having passed through the slit of the housing to an electric signal; and an optical system for guiding the light rays having passed through the slit of the housing to the photoelectric conversion element. The housing has a light restrictor at each of the both ends of the slit. The light restrictor projects toward the image bearing surface of the document to thereby keep light rays reflected from an area outside a reading area of the image bearing surface of the document from entering the slit.
    • 一种用于产生对应于文件图像的图像数据的图像读取装置,包括:用于将光线照射到文件的图像承载表面上的照射部分; 壳体,形成有狭缝,用于限制从所述文件的图像承载表面反射的光线; 光电转换元件,用于将通过壳体的狭缝的光线形成的光学图像转换成电信号; 以及用于将已经穿过壳体的狭缝的光线引导到光电转换元件的光学系统。 壳体在狭缝的两端的每一端具有限流器。 光限制器朝向文件的图像承载表面突出,从而保持从文档的图像承载表面的读取区域外部的区域反射的光线进入狭缝。
