    • A document reading apparatus includes a document positioning plate configured to position a document, a carriage configured to move a light source along the document positioning plate, a reading unit configured to read an image of a document illuminated by a light source of the carriage, a white reference member provided in the displacement range of the carriage, an input unit configured to input a reading start instruction for a document, and a control unit configured to move the carriage along the document positioning plate in response to a reading start instruction input via the input unit. The control unit moves the carriage to a first position at which the white reference member is provided, cause the reading unit to read the white reference member, moves the carriage to a second position that is an acceleration start position for accelerating toward the reading start position of the document positioning plate, and waits for a reading start instruction input from the input unit.

    • An image reading apparatus that, in a case where the light amount of light illuminated from an image reading lamp has decreased, maintains the quality of a read image without decreasing productivity, and a method for controlling that image reading apparatus, are provided. To accomplish this, this image reading apparatus is provided with RGB line sensors that read a color image, and a monochrome line sensor that reads a monochrome image and has a faster horizontal transfer speed than the RGB line sensors. Further, this image reading apparatus reads a monochrome image using the RGB line sensors even in a monochrome mode in a case where the light amount of the lamp for illuminating an original decreases and so an output level for reading an image with good quality cannot be obtained from the monochrome line sensor.
    • 一种图像读取装置,在从图像读取灯照射的光的光量减少的情况下,保持读取图像的质量而不降低生产率,并且提供了一种用于控制该图像读取装置的方法。 为了实现这一点,该图像读取装置设置有读取彩色图像的RGB线传感器和读取单色图像并且具有比RGB线传感器更快的水平传送速度的单色线传感器。 此外,即使在用于照亮原稿的灯的光量减少的情况下,即使在单色模式下,该图像读取装置也使用RGB线传感器读取单色图像,因此不能获得用于读取质量好的图像的输出电平 从单色线传感器。
