    • A document reading apparatus including: a first scanning section that moves in a scanning direction along a document surface, for supporting a first mirror to reflect an image of a document in a direction parallel to the scanning direction; an intermediate scanning section that moves synchronous with the first scanning section, for supporting an intermediate mirror to reflect the image of the document reflected by the first mirror in a direction opposite from an incident direction of the image; a reading section including an imaging sensor for reading the image of a scanned document and a focusing lens for focusing the image of the document reflected by the intermediate mirror on the imaging sensor; a driving wire for pulling the first scanning section in the scanning direction; a supporting pulley for supporting the driving wire at a starting side for scanning or at an ending side for scanning; a position adjustment section capable of adjusting a position of the supporting pulley in its axial direction; a control section for performing such control that the image for adjustment is read by the reading section when the first scanning section is located at a first position and at a second position in the scanning direction, and an adjustment amount of the position adjustment section is calculated based on a readout result of the image; and an output section for outputting the calculated adjustment amount.
    • 一种文件读取装置,包括:第一扫描部,其沿文件表面沿扫描方向移动,用于支撑第一反射镜以在与扫描方向平行的方向上反射原稿的图像; 中间扫描部,其与第一扫描部同步移动,用于支撑中间反射镜,以反射与第一反射镜反射的文件的图像在与图像的入射方向相反的方向上; 读取部分,包括用于读取扫描文档的图像的成像传感器和用于将由中间反射镜反射的原稿的图像聚焦在成像传感器上的聚焦透镜; 用于沿扫描方向拉动第一扫描部分的驱动线; 用于在用于扫描的起始侧支撑驱动线的支撑皮带轮或用于扫描的终止侧; 位置调整部,其能够调整所述支撑皮带轮的轴向位置; 控制部分,用于当第一扫描部分位于扫描方向上的第一位置和第二位置时,由读取部分读取调节图像,并且计算位置调整部分的调整量 基于图像的读出结果; 以及输出部,用于输出计算出的调整量。
