Illuminating device, image reading apparatus including the illuminating device, and image forming apparatus including the image reading apparatus
Abstract:
An illuminating device capable of stably illuminating an irradiated object such as a document while suppressing light loss with a simply structure is provided.An LED array (71) and a reflective plate (73) are disposed sandwiching a slit (St) through which light reflected by a document MS passes and a light-guiding member (72) is disposed on the side of the LED array (71). The light-guiding member (72) includes a direct emission unit (77) disposed between an illumination range y centered on a document reading position and the LED array (71) and an indirect emission unit (78) disposed between the reflective plate (73) and the LED array (71), a light incidence face of the direct emission unit (77) and a light incidence face of the indirect emission unit (78) are disposed at mutually different position around the LED array (71), and the LED array (71) is disposed on a side of an interior angle formed by the light incidence faces.
Abstract(Chinese):

提供能够以简单的结构抑制光损失的同时稳定地照射诸如文件的被照射物体的照明装置。 将LED阵列（71）和反射板（73）设置成夹着由文件MS反射的光通过的狭缝（St），并且在LED阵列（71）侧设置有导光构件（72） ）。 导光构件（72）包括设置在以文件读取位置为中心的照明范围y和LED阵列（71）之间的直接发射单元（77）和设置在反射板（73）之间的间接发射单元（78） ）和LED阵列（71），直接发射单元（77）的入射面和间接发射单元（78）的光入射面设置在LED阵列（71）周围的相互不同的位置，并且 LED阵列（71）设置在由入射面形成的内角的一侧。
