摘要： In an image reading apparatus having an easy-toad-just optical system, a unit is composed of a first sub-unit including an image forming lens and a second sub-unit including a solid-state image pickup element. The first sub-unit and the second sub-unit are mutually adjusted in position in X-axis, Y-axis and Z-axis while the two sub-units are also adjustable around X-axis and Z-axis. After the first sub-unit and the second sub-unit are adjusted using a tool, the unit is then assembled into the apparatus. The unit is rotated around an optical axis of the image forming lens for adjustment of perpendicularity. The unit is also rotated around a line direction of the solid-state image pickup element for adjustment of scanning synchronization (the reading position in a sub-scan direction).

An optical path length, or a distance from a deflection point of the deflecting unit to a surface to be scanned, of an imaging optical system to form an image onto a surface to be scanned closest to the deflecting unit is different from that of an imaging optical system to form an image onto a surface to be scanned farthest from the deflecting unit.

摘要： It is an object of this invention to provide a light scanning device capable of suppressing a scanning line bend to a low level, which is caused by the arrangement error of a single-element lens serving as an imaging optical element, and an image forming apparatus using the device. In order to achieve the object, according to this invention, an imaging optical system is formed from a single-element lens, and a sectional shape of an exit surface in the main scanning direction is an arcuated shape. The power in the sub scanning direction substantially concentrates on the exit surface having an arcuated sectional shape in the main scanning direction, and the arcuated shape (curvature) in the main scanning direction is so determined as to make the magnification in the sub scanning direction uniform.
