20090153674 | IMAGE READING APPARATUS - An original is inclined with respect to an optical axis of a camera until the camera is positioned outside a reflected-image taking range by inclining a mounting surface of an original glass on which the original is placed. This makes it possible, when the original is taken by the camera, to prevent the camera from being reflected on the original and being taken in with the original. An imaging case formed of a diffusing member that is made of a high light-diffusing material or a high light-absorbing material is arranged in the reflected-image taking range. This makes it possible to prevent an object positioned in the reflected-image taking range from being reflected on the original and being taken by the camera. Consequently, clear image information can be more reliably obtained. | 06-18-2009 |
20090200477 | IMAGE READER - In an image reader, if a first and second light sources alternately light-up when a conveying unit conveys an imaging target medium, a visible light data group that is based on a reflected light, of a wavelength inside a visible spectrum, of a first light having a wavelength inside the visible spectrum and a visible light external data group that is based on the reflected light, of the wavelength inside the visible spectrum, of a second light having a wavelength outside the visible spectrum are alternately generated. By scanning the imaging target medium once and by collecting multiple visible light data group, first image data of the imaging target medium, based on the first light, is generated. Furthermore, by collecting multiple visible light external data group, second image data of the imaging target medium, based on the second light, is also generated. | 08-13-2009 |

20140354867 | LINEAR LIGHT SOURCE APPARATUS AND IMAGE READING APPARATUS - A linear light source apparatus is provided, being configured to convert light emitted from one light emitting element to light extended linearly, and output thus converted light. There is a lens that diffuses light flux within a predetermined region including the optical axis of the light emitting element, out of the light incident from the light emitting element, at a predetermined diffusion angle in the second direction (x-direction). The light is made to converge with respect to the first direction (y-direction). This converts the light from one light emitting element to light extended linearly and outputs the converted light. As for the second direction (x-direction), it is possible to make the light flux sparse in the predetermined region, and in the region outside thereof, the light flux is rendered to be dense. Therefore, a distribution of light quantity in the longitudinal direction (x-direction) is implemented by controlling the light flux density, upon employing the linear light source apparatus as a light source of the image reading apparatus. | 12-04-2014 |
