    • An image reading device, which has an image sensor having a plurality of sensor chips therein and being capable of outputting data in parallel through a plurality of output channels, includes an image reading section configured to perform reading of images in either of two outputting modes, one being a parallel outputting mode in which start signals are simultaneously inputted to the plurality of sensor chips so that pieces of data in the plurality of the sensor chips are outputted in parallel through the plurality of output channels, respectively, the other one being an interval outputting mode in which start signals are sequentially inputted to the plurality of sensor chips at intervals of time between any two successive inputs of the start signals, respectively, so that respective pieces of data in the plurality of sensor chips are sequentially outputted through any one of the plurality of output channels, and a mode selection section configured to select either of the two outputting modes in accordance with a set resolution.
    • 一种具有图像传感器的图像读取装置,其中具有多个传感器芯片,并且能够通过多个输出通道并行地输出数据,所述图像读取装置包括:图像读取部,被配置为以两种输出模式中的任一种进行图像的读取; 一个是并行输出模式,其中开始信号被同时输入到多个传感器芯片,使得多个传感器芯片中的数据分别通过多个输出通道并行输出,另一个是间隔 输出模式,其中开始信号分别以起始信号的任意两个连续输入之间的时间间隔依次输入到多个传感器芯片,使得多个传感器芯片中的各个数据通过以下任何一个依次输出: 所述多个输出通道,以及被配置为选择所述两个输出信号中的任一个的模式选择部 g模式根据设定的分辨率。
