摘要： An automatic document handler for a duplex copier is disclosed in which an inverting drum is employed for inverting documents which are to be copied on both sides (duplex copying). The inverting drum is provided with pressure or transport belts which carry a document over a portion of the surface of said drum, and a diverter gate arrangement is provided at the exit side of the belts, adjacent the drum, for selectively providing for passage of the document to a collection station, or alternatively, for causing the documents to re-enter toward the drum for delivery to a duplex scanning station. The diverter gate arrangement includes a relatively fixed stripper which is positioned adjacent the surface of the drum, which stripper cooperates with a movable gate. In one position of the gate, a nose portion of the gate is nested with the stripper and permits documents to pass thereover to a collection station. In a second position, the gate intercepts documents from the stripper and from the pressure belts and causes the same to be redirected toward the drum for duplex copying.
摘要翻译：公开了一种用于双面复印机的自动文件处理器，其中使用翻转滚筒来翻转要在两侧复印的文稿（双面复印）。翻转滚筒设置有压力传送带，其携带在所述滚筒的表面的一部分上的文件，并且转向门装置设置在带的出口侧，邻近滚筒，用于选择性地提供或者替代地，使文档重新进入鼓以传送到双面扫描站。分流门装置包括相对固定的剥离器，其位于滚筒的表面附近，该剥离器与可移动的浇口配合。在门的一个位置，门的鼻部与剥离器嵌套，并允许文件通过其到收集站。在第二位置，闸门拦截来自剥离器和压力带的文件，并使其相对于滚筒重新定向以进行双面复印。

摘要： A compact plotter is disclosed, having a small area in which a plurality of print heads (10) are laterally scanned to print impressions on the paper (14), and the paper (14) is incrementally advanced by an indexer (42) past the print heads (10). A paper travel encoder (36) measures the paper advancement. A computer 22 and a processor 26 are provided to coordinate the printing of pattern data stored in a data base (24) both with the movement of the print heads (10) and the advancement of the paper (14). The computer (22) allocates data from the data base (24) to be printed according to the amount of paper advancement. If the paper (14) is advanced more than a predefined amount, more data is allocated for printing than is actually printed. If the paper (14) is advanced less than the predefined amount, less data is allocated to be printed than is actually printed.
摘要翻译：公开了一种小型绘图仪，其具有小的区域，其中多个打印头（10）被横向扫描以在纸张（14）上印刷印模，并且纸张（14）由分度器（42）逐渐前进通过打印头（10）。纸张行进编码器（36）测量纸张进给。提供计算机22和处理器26，以随着打印头（10）的移动和纸（14）的前进来协调存储在数据库（24）中的图案数据的打印。计算机（22）根据纸张进给量从要打印的数据库（24）分配数据。如果纸张（14）超过预定义的数量，则为打印分配更多的数据，而不是实际打印的数据。如果纸张（14）的进给速度小于预定义的数量，则比实际打印的数据分配更少的数据被打印。
