    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.

    Abstract: PROBLEM TO BE SOLVED: To enable an optical device which is constituted of light-receiving elements and light-emitting elements that are arranged in an array form, to be reduced in number of adjustments and positional displacement due to thermal expansion and shrinkage.
    SOLUTION: The optical device is equipped with optical element groups 20, which are used for reading or writing and moves physically accompanying a reading plane or a writing plane. In the optical device, where the adjacent optical element group 20 from among the optical element groups 20 is arranged at a prescribed distance in the physically moving direction, a board 22, on which the optical element group 20 is mounted, is linked to the board 22 on which the adjacent optical element group 20 is mounted, by a holding member, 24 whose thermal expansion coefficient is smaller than that of the board 22 for maintaining a prescribed distance Py. At this point, distance Qy, between the bonding positions of the holding member 24 that links the board 22 together, is set longer than the prescribed distance Py.
