    Abstract: An image reading apparatus includes a CCD sensor which reads an image of an original document and converts the image into an electrical signal, in which an optical axis of light reflected by the original document is adjusted and allowed to project to the CCD sensor, the CCD sensor reads the image of the original document and converts the image into an electrical signal and to output the electrical signal. The image reading apparatus comprises a processing circuit which detects a CCD output value of the CCD sensor which is varied in accordance with a deviation of the optical axis, and an optical axis adjusting mechanism (first mirror and first carriages) which adjusts the optical axis such that an output value detected by the processing circuit becomes an appropriate value. The optical axis adjusting mechanism comprises a mirror which reflects light from the original document in a set direction, a fixing/supporting projection which supports the mirror at a given position, an optical axis adjusting screw which supports the mirror together with the fixing/supporting projection, and which turns the mirror by screwing or loosening the screw, thereby adjusting the optical axis, and an elastic supporting projection 29 which abuts from an opposite surface and elastically supports the mirror in a state in which adjustment by the optical axis adjusting screw is permitted.

    Abstract: An original reading unit is provided that is superior in the performance of the adjustment of line sensors. According to the present invention, between a unit base and a transparent original support plate, multiple sensor assemblies are arranged, to form a zigzag pattern, as a first array for reading an original and a second array for reading the original following the first array. Each of the sensor assemblies includes a sensor holder, a line sensor and a focus setup unit. Each of the sensor holders, which serve as fulcrums, are rotatable at a single pivot (a rotation center), along the wall of a unit base that is parallel to the original support plate. When the sensor holders are rotated and positioned at predetermined locations, they are fixed to the wall. The line sensors 51 are held, relative to the sensor holders, in the main scanning direction and in the sub-scanning direction, and are moved in an approaching or separating direction in which the line sensors approach or are separated from the wall and the original support plate. The focus setup units, each of which includes coil springs and spacers, move the line sensors 51 in the approaching or separating direction, and position the line sensors 51 at locations whereat focuses are adjusted.
