| 20100124439 | ILLUMINATING DEVICE, IMAGE-READING APPARATUS, AND IMAGE-FORMING EQUIPMENT - An embodiment of the present invention provides an illuminating device that is disposed in an image-reading apparatus and image-forming equipment, comprising: a light-source portion on one side; a light-source portion on the other side; and a long translucent light-guiding member having a light-discharging face long in a longitudinal direction thereof, and guiding light derived from the one light-source portion from one end face in the longitudinal direction, and light derived from the other light-source portion from the other end face in the longitudinal direction so that the guided light is irradiated to an object through the long light-discharging face; wherein the one and the other light-source portions are arranged such that positions of optical axes thereof differ from each other. | 05-20-2010 |
| 20100245944 | IMAGE READING APPARATUS AND IMAGE FORMING APPARATUS - In regard to a secured original method, an image reading apparatus provided in an image forming apparatus reads a first original guide using an original reading portion and, based on a reading result thereof, changes a reading position of an adjustment sheet in a main scanning direction to enable detection of a difference between a brightness of the first original guide and a brightness of the adjustment sheet. In regard to a moving original method, the image reading apparatus reads a reading member using the original reading portion and, based on a reading result thereof, changes a reading position of an adjustment sheet in a main scanning direction to enable detection of a difference between a brightness of the reading member and a brightness of the adjustment sheet. | 09-30-2010 |
| 20100290095 | LIGHT SOURCE APPARATUS, LIGHT IRRADIATING APPARATUS PROVIDED WITH SAME LIGHT SOURCE APPARATUS, IMAGE READING APPARATUS PROVIDED WITH SAME LIGHT IRRADIATING APPARATUS, AND IMAGE FORMING APPARATUS PROVIDED WITH SAME IMAGE READING APPARATUS - In one embodiment of a semiconductor apparatus of the present invention, a plurality of light-emitting elements provided with a light-emitting face are disposed at intervals in a line on a surface of a substrate, and serve as a light source apparatus that emits irradiating light forward from the light-emitting face along the surface of the substrate, and on a forward side of the light-emitting face in the surface of the substrate, a light reflection suppression area is formed extending forward with a width less than the width of the light-emitting face from a lower edge of the light-emitting face. | 11-18-2010 |

| 20110164899 | ILLUMINATING DEVICE, IMAGE-READING APPARATUS COMPRISING THE ILLUMINATING DEVICE, AND IMAGE-FORMING APPARATUS COMPRISING THE IMAGE-READING APPARATUS - An illuminating device includes a light-emitting element that is mounted on a base material and a light-guiding member that guides light from the light-emitting element to an irradiation target, and illuminates the irradiation target with the light transmitted through the light-guiding member. The light-guiding member includes an extending portion that extends from the surface of the base material on which the light-emitting element is mounted to a left side end portion of the base material so as to cover the left side end portion. An image-reading includes this illuminating device. Image-forming apparatus includes this image-reading apparatus. | 07-07-2011 |
| 20110199652 | ILLUMINATING DEVICE, IMAGE-READING APPARATUS PROVIDED WITH THE ILLUMINATING DEVICE, AND IMAGE-FORMING APPARATUS PROVIDED WITH THE IMAGE-READING APPARATUS - The present invention provides an illuminating device including a plurality of light-emitting elements arranged in a line, the illuminating device illuminates an irradiation target by irradiating the irradiation target with light that is emitted from the light-emitting elements via a first and a second optical paths. In the illuminating device, a light diffusing portion for diffusing light is provided in one of the first optical path and the second optical path, and an irradiation light amount of said one of the first optical path and the second optical path in which the light diffusing portion is provided is larger than an irradiation light amount of the other optical path. | 08-18-2011 |
