    摘要： A movable document handling system, or module, is utilized on a modified standard office copier. When the document handling module is moved away from the platen glass area, the document handling module equipment is disabled and the office copier may be used as a standard copier. When, however, the document handling module is moved over the platen glass, other optics and document handling apparatus are now energized and the standard office copier is now converted into a large document copier. The document handling module can be operated in either of the two positions for service and maintenance. Dual sets of gas spring apparatus is provided, wherein one or both gas springs in each set are in use for increased mechanical assistance in raising the document handling module when in place over the standard glass platen area. When the module is positioned away from the platen area, less mechanical assistance is required due to the shift on the module's center of gravity and only one in each dual sets of gas springs are allowed to actuate, said selective operation being controlled by the requisite mechanical linkages and assemblies.

    摘要翻译： 可移动文件处理系统或模块被用于经修改的标准办公复印机。 当文件处理模块远离稿台玻璃区域时，文档处理模块设备被禁用，办公室复印机可以用作标准复印机。 然而，当文件处理模块移动到稿台玻璃上时，其他光学元件和文件处理装置现在被通电，并且标准办公复印机现在被转换成大型文件复印机。 文档处理模块可以在两个位置中的任一个中进行操作以进行维护和维护。 提供双组气弹簧装置，其中每组中的一个或两个气弹簧用于在标准玻璃压板区域上的适当位置时提升文件处理模块的机械辅助。 当模块远离压板区域时，由于模块重心的移动，需要较少的机械辅助，并且每两组气弹簧中只有一个允许启动，所述选择操作由必要的机械 联系和组件。
