摘要： An irradiation device increasing the lighting depth and facilitating the assembling is provided. A transparent bar-shaped light guide having LEDs disposed near ends thereof includes a first prism group and a first reflector, and, a second prism group and a reflector which are provided so as to extend in a lengthwise direction and which diffuse and reflect light. The light guide includes a first light outgoing area emitting reflected light as primary light Lm, and a second light outgoing area emitting reflected light as secondary light Ls. The first light outgoing area includes a plane portion forming a flat surface. A plane mirror reflects the secondary light Ls in a direction overlapping the primary light Lm in a read area.

摘要： An image reading apparatus includes a light source, an imaging optics system, an image pickup device unit, a memory, and a processor. The imaging optics system condenses scattered light reflected on an object to be imaged to form condensed light as an image. The imaging optics system includes plural cells arranged in a main scanning direction and each of which is an independent imaging optics system. Each of the cells includes a telecentric optics system at the document side. Two rows of cells are arranged in a sub-scanning direction. The cells in the rows are arranged zigzag in the main scanning direction to complement a formed image by the cells in the sub-scanning direction. The image pickup device unit is arranged to correspond to each cell. The processor can form a document image by reconstructing and combining image information stored in the memory into an image.
