摘要： A light guide plate is provided including a first lens portion comprising a plurality of recessed or projected lenticular unit lenses formed of the same resin as that of the light guide plate on a light emission surface. The plurality of lenticular unit lenses in the first lens portion are triangular prism portions whose respective vertexes have an angle of 125.degree. to 165.degree. and are so arranged that their respective ridge lines are nearly parallel to each other. Such construction makes it possible to set the number of lenticular lens sheets used to one or to further eliminate the necessity of the lenticular lens sheets, so that the cost of parts and the fabrication cost of the light guide plate can be reduced. A second lens portion may be provided on a light reflective surface opposite to the light emission surface on which the first lens portion is disposed, the second lens portion including a plurality of recessed or projected lenticular unit lenses formed of the same resin as that of the light guide plate. Alternatively, a light guide plate is provided having a plurality of grooves with approximately equal groove widths formed on a surface opposite to a light emission surface, the grooves being arranged substantially parallel to each other and the spacing between the grooves narrowing as the distance from the light incident surface increases, with the spacing from the far end of one of the plurality of grooves proximate to the light incident surface to the near end of a groove adjacent thereto farther away from the light incident surface being 5 to 15 times the groove width.
摘要翻译：提供了一种导光板，包括：第一透镜部分，包括由与发光表面上的导光板相同的树脂形成的多个凹入或突出的双凸透镜单元透镜。第一透镜部分中的多个透镜单元透镜是三角形棱镜部分，其各自的顶点具有125°至165°的角度，并且被布置成使得它们各自的脊线彼此几乎平行。这样的结构使得可以将使用的双凸透镜片的数量设置为一个，或者进一步消除双凸透镜片的必要性，从而可以减少导光板的部件成本和制造成本。第二透镜部分可以设置在与其上设置有第一透镜部分的光发射表面相对的光反射表面上，第二透镜部分包括由与第一透镜部分相同的树脂形成的多个凹入或突出的双凸透镜单元透镜导光板。或者，导光板设置有多个槽，其在与发光表面相对的表面上形成有大致相等的槽宽，所述槽基本上彼此平行地布置，并且槽之间的间距随着距离光入射面增加，与多个凹槽中的一个接近光入射表面的远端的距离相对于与光入射表面相邻的凹槽的近端的距离为凹槽宽度的5至15倍。

摘要： An outer light collecting portion 10 which sticks out of a light emission surface 14 to the light emission direction at the same time when a light guide plate is formed by resin forming with a mold. An area of a surface for collecting outer light is larger than that of a conventional light guide plate so as to collect outer light effectively. Light from a light source which is incidence through a light incident surface 12 reflects from a light reflection surface 13 and two side surface 11 of a light guide plate 1, and is emitted as synthesized light having the even directivity from a light emission surface 14.

摘要： An image forming apparatus includes a photoreceptor including a glass substrate and a photoconductive layer laminated thereon. A toner box is provided in the vicinity of the photoreceptor, in which a mixed toner including an insulative non-magnetic toner and a conductive magnetic toner is contained. At an opening of the toner box, a magnetic roller and a developing sleeve which is rotatably put on the magnetic roller are arranged, and a magnetic brush of the mixed toner is formed according to a rotation of the developing sleeve so that the mixed toner is brought into contact with the photoconductive layer. A developing bias having the same polarity as a charged polarity of the insulative non-magnetic toner is applied between the developing sleeve and the photoconductive layer and, at the same time, an exposure light is projected from an LED array on the photoconductive layer through the glass substrate.

摘要： The present invention provides a light guide plate and a surface light source using the light guide plate to improve the utilization efficiency of external light and light from an internal light source and to achieve thinner width of the light guide plate. In this invention, internal light emitted from an internal light source 3 is brought to the inside of the light guide plate 1 from an internal light collecting surface 16 in the light guide plate 1, and external light such as natural light is brought to the inside of the light guide plate 1 from an external light collecting portion 11. The light brought to the inside of the light guide plate reflects and is converged several times from a reflective plate 15 mounted to the outside of the light reflective surface 14 and three side end surfaces 12 and is emitted from the light emissive surface 13 of the light guide plate 1 to a diffusing plate 6. The light incident to the diffusing plate 6 is diffused uniformly within the desired angle range by the diffusing plate 6 and a lens sheet 7, and is emitted from the lens sheet 7 as synthesized light.
