    摘要： An automatic document feeding device includes a conveyance unit, an image reading unit, a color reference member, a moving assembly, and a drive source. The conveyance unit conveys a document to an image reading position. The image reading unit reads an image of the document. The color reference member faces the image reading unit and includes a white reference face to correct shading. The moving assembly relatively moves the image reading unit and the color reference member. The movement regulator regulates a relative movement of the image reading unit and the color reference member by the moving assembly. The drive source includes a common rotation output shaft to drive the conveyance unit and the moving assembly. The drive source changes the rotation output shaft from a forward rotation direction to a reverse rotation direction to reversely rotate the rotation output shaft to a set reverse rotation angle set in advance, according to a condition of conveyance of the document by the conveyance unit. In a rotation transmission route from the rotation output shaft to the moving assembly, the movement regulator is disposed in a first reverse rotation drive region from when a rotation direction of the rotation output shaft is changed to the reverse rotation direction to when a rotation angle of the rotation output shaft after the change in the reverse rotation direction reaches the set revere rotation angle. The moving assembly relatively moves the image reading unit and the color reference member in a second reverse rotation drive region where the rotation output shaft is rotated in the reverse rotation direction beyond the set reverse rotation angle.

    摘要翻译： 自动送稿装置包括输送单元，图像读取单元，颜色基准元件，移动组件和驱动源。 传送单元将文档传送到图像读取位置。 图像读取单元读取文档的图像。 颜色参考构件朝向图像读取单元并且包括白色参考面以校正阴影。 移动组件相对移动图像读取单元和颜色参考构件。 移动调节器通过移动组件调节图像读取单元和颜色参考构件的相对运动。 驱动源包括用于驱动输送单元和移动组件的公共旋转输出轴。 驱动源根据传送单元传送文件的状态，将旋转输出轴从正旋转方向改变为反转方向，以使旋转输出轴反向旋转到预先设定的反转旋转角度。 在从旋转输出轴到移动组件的旋转传递路径中，移动调节器设置在第一反向旋转驱动区域中，从旋转输出轴的旋转方向变为反转方向时，旋转输出轴的旋转角度 旋转输出轴在反转方向变化后达到设定的旋转角度。 移动组件相对地使图像读取单元和颜色基准构件在旋转输出轴以反转方向旋转超过设定的反向旋转角度的第二反向旋转驱动区域中移动。
