    Abstract: In an image reading apparatus having an easy-to-adjust 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).

    Abstract: PROBLEM TO BE SOLVED: To provide an image reading apparatus in which the optical adjustment of mirrors is facilitated when supporting carriages, on which the mirrors are mounted, on right and left rail surfaces movably along a platen.
    SOLUTION: The image reading apparatus is configured to guide reflection light from a document to an image reading means 11 through first and second carriages 3 and 4 moving at a predetermined speed along a document image on a platen. The first carriage 3 supports a mirror at three points such that a one-side end of a mirror is supported by first and second mirror supporting parts 32a and 32b and an other-side end is supported by a third mirror supporting part 32c. Both-side ends of the first carriage are then supported to be slidable on a pair of right and left rail members 5a and 5b through slide members 33a-33d disposed at two positions on forward and backward sides, respectively, at four positions on right and left sides. At least one of the slide members 33c and 33d at two positions on the forward and backward sides disposed at a side of the third mirror supporting part supporting the first mirror at one point is supported by an adjustment screw or the like so as to adjust its position in height.

    Abstract: An image reading apparatus has a platen, first and second carriages, a light source supported on the first carriage, a first mirror to deflect reflected light from the original document toward the second carriage, one or more second mirrors supported on the second carriage to guide the light from the first mirror to image reading device, and rail members. The first carriage has first and second mirror support portions for supporting one side edge portion of the first mirror by two points, and a third mirror support portion for supporting the other side edge portion by one point. The first carriage is supported slidably at its opposite side edge portions respectively on the rail members via slide members disposed at four right and left places including two front and back places, and a height position is adjustable for supporting the first mirror by one point.
