    摘要： Variation in the illuminance of a light source device in the longitudinal direction is suppressed and the emitted light is efficiently emitted to an illuminated object. A light guide (3) propagates light emitted by a light source (1) and entering therein from an end in the long axis direction. A fluorescent material layer (5) surrounds the outer periphery of the light guide (3) except for an opening along the long axis direction, absorbs part of the light exiting from the periphery of the light guide (3), and emits fluorescence. A light reflecting pattern is provided on the outer periphery of the light guide (3) opposite to the fluorescent material layer (5). In the course of the light having entered therein from the end being propagated in the light guide (3), the fluorescent material layer (5) captures light reflected by the light reflecting pattern and exiting from the outer periphery of the light guide (3), reflects part of the light, and emits light of different wavelengths. Then, the light emitted by the fluorescent material layer (5) is transmitted into the light guide (3), and the light having entered therein from the end and the light emitted by the fluorescent material layer are emitted to the illuminated object from a portion of the light guide (3) that is exposed or protruding in the opening of the fluorescent material layer (5).

    摘要： An image reading apparatus includes a light source (2), an imaging optics system (1), an image pickup device unit (41; 42,..), a memory (5), and a processor (6). The imaging optics system is an optics system for condensing scattered light reflected on an object to be imaged to form such condensed light as an image. The imaging optics system has a plurality of cells (11, 12,..) and the like which are arranged in a main scanning direction (211) and each of which is an independent imaging optics system. Each of the cells (11, 12,..) has a telecentric optics system at the side of the document. Two rows of cells are arranged in a sub-scanning direction (212). The cells (11, 12,..) in the rows are arranged zigzag in the main scanning direction so as to be able to complement a formed image by the cells in the sub-scanning direction (212). The image pickup device unit (41, 42,..) is arranged to correspond to each cell. The processor (6) can form a document image by reconstructing and combining image information stored in the memory (5) into an image.

    摘要： A light source device comprises a housing (101) and light emitters (156, 157). The housing (101) includes, for example, a floor having a rectangular shape, a long-edge wall, a sloped face, short-edge walls and heat-sinks. The long-edge wall is a portion bent inwards from the floor along the long edge on one side of the floor. The sloped face is a portion forming a mirror surface bent inwards at a designated angle from the floor in the short-edge direction of the floor along the long edge on the other side of the floor. The short-edge walls are portions bent inwards from the floor along the short edges of the floor. The heat-sinks are continuous with the short-edge walls, bent in the long-edge direction, and extending in the long-edge direction facing in the direction opposite the long-edge wall with respect to the sloped face.
