摘要：
An image scanning device includes a first scanner (141) scanning a top side of a transported document at a first scanning position (L1) to obtain a first scanned image, a second scanner (129) scanning the back side of the transported document at a second scanning position (L2) to obtain a second scanned image, a document feeder (63-70, 161) transporting a document at the second scanning position at a speed differing from the transportation speed at the first scanning position, and a controller (20) controlling the image scanning device. The controller sets, as a scanning form of a document, either one-side scanning of scanning one side of a document through one transportation, or dual-side scanning of scanning both sides of a document through one transportation. The controller also obtains a set magnification. The controller determines the transportation speed by the document feeder such that, when one-side scanning is set, the scanning magnification in a first direction corresponding to the document transportation direction at the first scanned image attains the set magnification, and when dual-side scanning is set, the scanning magnification in the first direction at the second scanned image attains the set magnification.
摘要（中）：
一种图像扫描装置包括：第一扫描仪（141）在第一扫描位置（L1）扫描被传送原稿的顶侧，以获得第一扫描图像;扫描被传送原稿的背面以第二扫描器（129） 第二扫描位置（L2），以获得第二扫描图像，送稿器（63-70，161）处的第一扫描位置从输送速度不同的速度的第二扫描位置输送的文档，以及控制器（20 ）控制图像扫描装置。 所述控制器设定的，如通过一个运输通过一个运输，或一个文件，扫描bothsides的双面扫描中扫描文档时，文档的扫描一侧中的任一个侧扫描的一种形式。 因此，控制器获得一组放大率。 控制器确定性地雷由文档进纸器寻求的是，搬送速度，当单面扫描被设置，在第一方向上对应于在第一扫描图像的原稿传送方向上的扫描倍率达到设置倍率，并且当双面扫描 被设置，在所述第二扫描图像的第一方向上的扫描倍率达到设置倍率。
