    • An image scanner includes a transparent plate, a scanning device, a driving device, a positioning member, a light absorbing portion and a white reference portion. The transparent plate has an original placing surface. The scanning device irradiates an original with light by means of a light source and scans reflected light from the original. The driving device reciprocates the scanning device along the transparent plate. The positioning member positions the original placed on the original placing surface of the transparent plate. The light absorbing portion, which is disposed on the original placing surface side of the positioning member and at substantially a central portion of the positioning member in moving directions of the scanning device, absorbs ambient light entering to the original placing surface side of the positioning member through the transparent plate. The white reference portion is provided to the original placing surface side of the positioning member.
    • 图像扫描器包括透明板,扫描装置,驱动装置,定位构件,光吸收部分和白色基准部分。 透明板具有原始放置面。 扫描装置利用光源照射原稿并扫描来自原稿的反射光。 驱动装置沿着透明板往复移动扫描装置。 定位构件使放置在透明板的原始放置表面上的原稿定位。 设置在定位构件的原始放置面侧的光吸收部和位于扫描装置的移动方向上的定位构件的大致中央部的吸光部吸收进入定位构件的原始放置面侧的环境光 通过透明板。 白色基准部分设置在定位部件的原始放置面侧。
