摘要： The present invention relates to handling of a sheet formed original to be scanned in an image scanner. In a preferred embodiment of the invention, the original is scanned by a trilinear CCD array, i.e. the original is scanned line by line, three lines at the time, one line for each color. Thus, at a specific time 'only' the area of the original that is scanned by the trilinear CCD array at that time has to be positioned in focus of the imaging means of the image scanner while the remaining part of the original may be positioned anywhere and may adopt any suitable form. Thus, there is no need for all parts of the original to be kept flat and planar as required in known flat bed scanners. According to the present invention, the original is kept flat and straight along a line to be scanned by imparting a substantially cylindrical shape, such as a circular cylindrical shape, to at least part of the original. The original is scanned along lines that are substantially parallel to the generatrix of the cylindrical part of the original. Thus, the fact that all parts of the original are not scanned simultaneously is exploited to simplify the positioning of the original in the image scanner compared to known methods and image scanners.

摘要翻译：本发明涉及在图像扫描仪中处理待扫描的片状原稿。在本发明的一个优选实施例中，原稿由三线CCD阵列扫描，即原稿逐行扫描，三行，此时为每种颜色一行。因此，在特定的时刻，在“只有”时，由三维CCD阵列扫描的原稿的区域必须定位在图像扫描仪的成像装置的焦点上，而原稿的剩余部分可以位于任何位置并可采用任何合适的形式。因此，在已知的平板扫描仪中，不需要将原件的所有部分保持平坦和平坦。根据本发明，通过使原稿的至少一部分赋予大致圆筒形状，例如圆筒形状，使原稿沿着待扫描的线保持平坦且平直。原稿沿着与原稿的圆柱形部分的母线基本平行的线扫描。因此，与已知的方法和图像扫描仪相比，利用原稿的所有部分不被同时扫描的事实来简化原稿在图像扫描仪中的定位。
