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 () and a reflective plate () are disposed sandwiching a slit (St) through which light reflected by a document MS passes and a light-guiding member () is disposed on the side of the LED array (). The light-guiding member () includes a direct emission unit () disposed between an illumination range y centered on a document reading position and the LED array () and an indirect emission unit () disposed between the reflective plate () and the LED array (), a light incidence face of the direct emission unit () and a light incidence face of the indirect emission unit () are disposed at mutually different position around the LED array (), and the LED array () is disposed on a side of an interior angle formed by the light incidence faces.
