    • In an image reading apparatus having a first original reading device for reading one side of an original guided and fed by a guide, and a second original reading device disposed downstream of the first original reading device for reading the other side of the original, the guide is bent between the first original reading device and the second original reading device so as to shield the respective reading devices. The bending of the guide is done by bending an original feeding path so that direct rays and diffraction rays from each of two light sources may not enter respective photoelectric transfer elements associated with other light source, to thereby shield the photoelectric transfer elements from light of a light source not associated therewith.
    • 在具有用于读取由引导件引导和馈送的原稿的一侧的第一原稿读取装置的图像读取装置中,以及设置在第一原稿读取装置的下游,用于读取原稿的另一侧的第二原稿读取装置, 在第一原稿读取装置和第二原稿读取装置之间弯曲,以屏蔽各个读取装置。 引导件的弯曲通过弯曲原始馈送路径来实现,使得来自两个光源中的每一个的直射线和衍射光线可能不会进入与其他光源相关联的相应的光电转移元件,从而将光电转移元件从光 光源不相关。

    • An image reading apparatus includes a document reading and conveying unit, a pressing plate capable of moving to a position to press a document against a reading surface and to a position withdrawn from the reading surface, and a fixed reader configured to read a document fixed on the reading surface by moving a close-coupled image sensor relative to the document. The document reading and conveying unit includes a controller configured to perform pickup initialization of returning a pickup roller to an initial position after the completion of conveying one or more documents and is supported by the pressure plate. The controller includes a first timer configured to measure an elapsed time from the completion of reading performed by the fixed reader. The controller performs the pickup initialization after a measurement value measured by the first timer exceeds a first time.
    • 一种图像读取装置,包括文件读取和传送单元,能够移动到将文件压靠在读取表面上的位置和从读取表面撤回的位置的按压板,以及固定读取器,其被配置为读取固定在 通过相对于文档移动紧密耦合的图像传感器来读取表面。 文件读取和传送单元包括控制器,其被配置为在传送一个或多个文档并且被压力板支撑之后执行将拾取辊返回到初始位置的拾取初始化。 控制器包括第一定时器,被配置为测量从固定读取器执行的读取完成所经过的时间。 在由第一定时器测量的测量值超过第一时间之后,控制器执行拾取初始化。

    • A sheet feeder has a feed cassette containing sheets to be supplied to an image forming unit in an image recording apparatus and able to be drawn out of the apparatus through a front portion of the apparatus, and another feed cassette able to be drawn out of the apparatus through a side portion. The feed cassette that can be drawn out through the side portion has a portion projecting outward from the side portion of the apparatus and located below a discharge tray for receiving sheets on which images are formed and which are discharged. This feed cassette can contain sheets having a size larger than the maximum size of recording sheets containable in the feed cassette drawn out through the front portion.
    • 供纸盒具有供纸盒,供纸盒供应到图像记录设备中的图像形成单元,并且能够通过设备的前部部分从设备中抽出,并且可以将其从 装置通过侧面部分。 可以通过侧部抽出的进料盒具有从装置的侧部向外突出的部分,并且位于排出托盘的下方,用于接收形成有图像并排出的片材。 该供给盒可以包含尺寸大于通过前部引出的供给盒中可记录的记录纸的最大尺寸的纸张。
