    • [Object] To avoid documents from colliding head-on with each other to be largely damaged in an image reader in which a conveyance route at the time of double-sided reading intersects with itself.
      [Means for Settlement] At a branch point C1, a path switching part 17 that switches between a double-sided path and a single-sided path is provided. The double-sided path is adapted to be a conveyance route that passes through a reading position C2 from the branch point C1 to enter a conveyance path B3 that makes a document A U-turn, and then again passes through the reading position C2 to be discharged to a paper discharge tray 12. On the other hand, the single-sided path is adapted to be a conveyance route that, without passing through the reading position C2, merges into the conveyance path B3 from the branch point C1. Over the double-sided path, document detecting sensors DS4 and DS5 are provided, and on the basis of detection results by them, a collision determination part 32 determines a possibility of a collision between documents, and if it determines that the documents will collide with each other, the path switching part 17 switches the double-sided path to the single-sided path to thereby avoid the documents from colliding head-on with each other in the vicinity of the reading position C2.
    • [对象]在双面读取时的传送路径与自身相交的图像读取器中,为了避免文档彼此正面碰撞而大大损坏。 [解决手段]在分支点C1设置有切换双面路径和单面路径的路径切换部17。 双面路径适合作为从分支点C1通过读取位置C2进入输送路径B3的输送路径,输送路径B3使文件A U形转弯,然后再次通过读取位置C2以成为 排出到排纸托盘12.另一方面,单面路径适合作为输送路径,其不经过读取位置C2,从分支点C1合并到输送路径B3中。 在双面路径上,提供了文档检测传感器DS4和DS5,并且基于它们的检测结果,碰撞确定部32确定文档之间碰撞的可能性,并且如果它确定文档将与 路径切换部分17将双面路径切换到单面路径,从而避免文件在读取位置C2附近彼此正面碰撞。

    • A method and apparatus of processing sheet media such as document sheets to be duplex scanned or media sheets on which two sided printing is to take place includes automatic positioning of an active sheet guide gate and drag clutch 70 by the rotation of a transport roller (50) with which the active gate and drag clutch is frictionally engaged. The transport roller may comprise one or more coaxial rollers (50) in an assembly positioned in the media path and is rotatable in different directions such that the leading edge of a moving media sheet is moved through one or the other of two nips defined between the transport roller assembly and associated upper and lower pinch rollers. The direction of rotation of the transport roller assembly can be reversed before the sheet leaves the nip to thus re-position the sheet guide gate and re-route the sheet back in a desired path to a scanner or printer for further sheet processing.
    • 处理片材介质的方法和装置,例如要进行双面扫描的文件片材或要在其上进行双面打印的介质片材,包括通过传送辊(50)的旋转自动定位活动片材引导门和拖拉式离合器70 ),有源门和拖曳离合器与其摩擦接合。 输送辊可以包括位于介质路径中的组件中的一个或多个同轴辊(50),并且可以沿不同的方向旋转,使得移动介质片的前缘移动通过两个位置之间限定的两个位置中的一个或另一个 运输辊组件和相关的上下夹送辊。 传送辊组件的旋转方向可以在纸张离开辊隙之前反转,从而重新定位纸张引导门,并且将纸张以期望的路径重新布置到扫描仪或打印机以进行纸张处理。
