    • An original scanning apparatus is described that scans an original placed on an original placing plane line by line by moving a scanning unit including a plurality of light-receiving elements that are arranged in a prescribed direction in a direction perpendicular to the prescribed direction. The original scanning apparatus includes: a pattern unit that is provided in a vicinity of a side of the rectangular original placing plane extending along a moving direction of the scanning unit; a control unit configured to calculate drive information in the moving direction per line-scanning cycle of the scanning unit based on a result of scanning the pattern unit; and a driving circuit configured to feed back the calculated drive information so as to control the scanning unit to thereby drive the scanning unit in the moving direction.
    • 描述了一种原始扫描设备,其通过沿着垂直于规定方向的方向移动包括沿规定方向布置的多个光接收元件的扫描单元逐行扫描放置在原始放置平面上的原稿。 原始扫描装置包括:图案单元,设置在沿着扫描单元的移动方向延伸的矩形原稿放置面的一侧附近; 控制单元,被配置为基于扫描所述图案单元的结果来计算所述扫描单元的每行扫描周期的移动方向上的驱动信息; 以及驱动电路,被配置为反馈所计算的驱动信息,以便控制扫描单元从而驱动扫描单元沿移动方向。

    • An image reading apparatus for reading an image on an original includes reading means for optically reading the image of the original while the image is illuminated by light from a light source; moving means for moving the reading means relative to the original; position signal generating means for outputting a position signal in accordance with movement of the reading means by the moving means; lighting control means for controlling the light source for lighting for a first period in synchronism with the position signal; output control means for generating a control signal for outputting an image signal corresponding to the image read by the reading means after the light source lights for the first period and for outputting the image signal for a second period in synchronism with the control signal.
    • 用于读取原稿上的图像的图像读取装置包括读取装置,用于在图像被来自光源的光照射的同时光学地读取原稿的图像; 移动装置,用于相对于原件移动读取装置; 位置信号发生装置,用于根据移动装置的读取装置的移动输出位置信号; 照明控制装置,用于与位置信号同步地控制用于第一时段的照明光源; 输出控制装置,用于在光源点亮第一时段之后产生用于输出与由读取装置读取的图像相对应的图像信号的控制信号,并且与控制信号同步地输出第二周期的图像信号。
