The f&thgr; lens includes a first lens that converges the beams mainly in the main scanning direction, and a second lens that converges the beams mainly in the auxiliary scanning direction. The first and second lenses are made of different materials. Further, one of the first and second lenses is formed integrally with the other using a mold such that the first and second lenses constitute a composite lens unit.

摘要： An image scanner includes first and second carriages, a body, a power source, a power supplier, and a tensioner. In the first carriage moving at a predetermined speed, a light source emits light onto an original. A first mirror deflects the light reflected by the original. In the second carriage moving at a half speed of the first carriage, second and third mirrors deflect the light deflected by the first and second mirrors, respectively. The body holds the first and second carriages. The power source drives the light source. The power supplier is connected to the power source and the light source to supply power from the power source to the light source. The tensioner provided on the second carriage contacts the power supplier at a position outside an optical light path and applies tension to the power supplier.

摘要： An image reading device includes a plurality of image reading units arranged at different positions in a width direction perpendicular to a conveyance direction of a recording medium to read an image on the recording medium at image reading positions and a conveyance roller pair that conveys the recording medium to the plurality of image reading units. The conveyance roller pair includes a drive roller and a driven roller that contacts the drive roller and rotates following the drive roller. The plurality of image reading units includes an upstream and a downstream image reading units downstream from the upstream image reading unit in the conveyance direction. A reading interval between the image reading positions and a diameter of the drive roller satisfy the relation: X2=n1×π×D1a, where X2 represents the reading interval, n1 represents an integer, and D1a represents the diameter of the drive roller.
