摘要： The invention provides an image reading apparatus structured such that two or more line image sensors are arranged in a main scanning direction, in which it is possible to securely restrict a position shift of an image reading area caused by a line image sensor, thereby performing an image reading operation at a high quality. In the image reading apparatus in which the line image sensors are arranged, a marker is formed as an image in an overlapping portion of the line image sensors, the marker is read by the line image sensors themselves so as to inspect a relative position between the line image sensors and the marker with reference to a magnitude of an output thereof corresponding to a judging standard, and the positions of the line image sensors are shifted on the basis of the result, thereby preventing a position shift in a sub scanning direction from being generated.

摘要： An image reading device reads an image of an original mounted on an original mounting base by using an optical scanning unit which is subjected to acceleration drive along the original mounting base until a velocity according to a reading magnification is obtained and then scanned by uniform velocity drive. A stepping motor moves the optical scanning unit. A reading magnification acceptance portion accepts a reading magnification of an image of the original mounted on the original mounting base. A motor drive control portion is used for control a drive electric current of the stepping motor, obliquely increases a set electric current during acceleration drive every velocity that the optical scanning unit reaches by a pulse number according to a reading magnification accepted by the reading magnification acceptance portion, and changes the set electric current value in accordance with the reading magnification so as to provide a characteristic for lowering the set electric current value at the time of shifting to uniform velocity drive. A photoelectric conversion portion converts a quantity of reflected light when the original on the original mounting base is optically scanned by the optical scanning unit moved by the stepping motor into an electrical signal.

摘要： In an image reading apparatus, the linear coefficients of expansion of conveyance drive rollers and a linear coefficient of expansion of the holding unit are determined such that the amount of change in the outer diameter of each of the conveyance drive rollers due to a change in temperature environment is substantially the same as the amount of change in the interval between the first reading unit and the second reading unit due to a change in the temperature environment. The conveyance drive rollers are attached to a rotary shaft such that the positions of head portions of screws are alternately located along the axis direction of the rotary shaft on opposite sides of the outer circumference surface in a direction perpendicular to the axis direction of the rotary shaft.
