    • A film scanner is provided with a line sensor for capturing an image formed on a film in a principal scanning direction, and a scanning mechanism for moving the film relative to the line sensor in an auxiliary scanning direction, which is perpendicular to the principal scanning direction. The scanning mechanism is provided with: a film holder for holding the film; a table for slidably mounting the film holder, the film holder being slidable in the auxiliary scanning direction; and a first driving system which drives the table in the auxiliary scanning direction at a first predetermined speed; and a second driving system which drives the film holder in the auxiliary scanning direction at a second predetermined speed, the second predetermined speed being faster than the first predetermined speed.
    • 一种胶片扫描器,具有用于拍摄在主扫描方向上形成在胶片上的图像的线传感器,以及扫描机构,用于沿着与主扫描方向垂直的辅助扫描方向相对于线传感器移动胶片 。 扫描机构设有:用于保持膜的胶片保持器; 用于可滑动地安装所述胶片保持器的台,所述胶片保持器能够在辅助扫描方向上滑动; 以及第一驱动系统,以第一预定速度在辅助扫描方向上驱动工作台; 以及第二驱动系统,其以辅助扫描方向以第二预定速度驱动所述胶片保持器,所述第二预定速度比所述第一预定速度快。
