摘要： To achieve a reduction in the cost of components and a reduction in assembly steps in a production line, the number of parts is reduced in an image reading apparatus. An image reading apparatus includes a casing which is provided with a unit to which light reflected from an original document surface is incident, a lens for converging the reflected light, an image sensor to which the reflected light which has been converged by the lens is incident, and a plurality of reflectors disposed between the light incident unit and the lens for defining an optical path for the reflected light. The reflectors are formed on the inner surface of the casing in a plurality of positions by vacuum depositing aluminum on the inner surface.

摘要： A document reading apparatus includes a light-source assembly which can provide the reduced number of parts and the effective use of light. The light-source assembly includes a plate and a holder. The plate has a reflective surface at one side thereof and a fixing surface at the other side thereof, wherein the plate is fixed at the fixing surface such that the reflective surface is placed in a predetermined direction. The holder is provided on the reflective surface of the one side of the plate. The holder holds and fixes the light source substantially parallel to the reflective surface.

摘要： An image data transfer system and method enable scan time and transfer time of the image data to be adjusted appropriately without lacking a part of the image data, suitable for low price. A data segmentation device segments the image data from a scan device into high order n bits and low order (N−n) bits, subsequently, transferring the high order n bits toward a data transfer device at the same time when the scan device scans a manuscript, and transferring the low order (N−n) bits toward a memory device. The data transfer device transfers the high order n bits of the image data toward a personal computer at the same time when the scan device scans the manuscript. The memory device stores therein the low order (N−n) bits of the image data temporarily. Furthermore, the data transfer device scans the low order (N−n) bits of the image data from the memory device to transfer toward the personal computer after transfer of the high order n bits.
