摘要： An impact printer has a print band moving longitudinally around pulleys with one side of the band moving in contact along a rigid platen and the other side having engraved characters presented along a print line of a print medium (e.g. paper and ink ribbon). The leading edge of platen is squared off (e.g. sharp) to scrape contamination off the band. A row of hammers impact the print medium against the band between the hammers and an impact surface of the platen. The impact surface of the platen contains multiple longitudinal grooves which start slightly back from the leading edge of the platen and which prevent increased friction force between the band and platen from occurring as the band wears the platen impact surface smooth.

摘要： A platen for a line printer has a polymer wear resistant strip on a base support. To reduce frictional drag on the band which is in sliding engagement with the wear strip, the leading edge of the strip is slanted against the direction of motion of the band and is provided with grooves that run perpendicular with the leading edge.

摘要： Method and apparatus for automatically producing a duplexed copy in a document copier machine wherein the leading edge of the rectangular copy sheet is maintained during both passes through the machine and wherein both simplexed and duplexed copies may be collated. This method and apparatus is especially useful when the leading edge is the narrow dimension of the rectangular copy paper.
摘要翻译： 在文件复印机中自动生成双面打印副本的方法和装置，其中矩形复印纸的前边缘在两次通过机器期间都被保持，并且其中可以整理单面和双面打印副本。 当前缘是矩形复印纸的窄尺寸时，该方法和装置特别有用。

摘要： A document feed mechanism for a copier machine incorporating an automatic document feed (ADF) with a semi-automatic document feed (SADF) and enabling the SADF to interrupt the ADF. The ADF tray upon which a stack of documents to be copied is placed is situated directly above the viewing station. A wave generator (shingler) paper feed means fans out the topmost sheets on the stack and up a ramp until the topmost sheet enters closed nip rollers. The nip rollers, together with aligner rollers and a drive belt, move the sheet around a substantially 180.degree. bend and onto the viewing station. Second sheet feeds are prevented by a restraint pad positioned between the nip rollers and the exit of the ramp, the top of the restraint pad being above the nip of the nip rollers so that the topmost sheet presses a second sheet downwardly into the restraint pad. The SADF feeds sheets onto the viewing station using the aligner rolls and the drive belt.
摘要翻译： 一种用于复印机的文档馈送机构，其包括具有半自动文档馈送（SADF）的自动文稿馈送（ADF），并使得SADF能够中断ADF。 要复制的一叠文件的ADF托盘位于观察台的正上方。 波发生器（定位器）进纸装置意味着排出堆叠上的最上面的纸张，并向上起斜坡，直到最上面的纸张进入闭合的压纸辊。 夹辊与校准辊和驱动带一起将片材大致180度弯曲地移动到观察台上。 通过位于夹持辊和斜面出口之间的限制垫来防止第二片进给，约束垫的顶部位于夹辊的辊隙之上，使得最上面的片向下挤压第二片向约束垫。 SADF使用对准辊和传动带将纸张送入观察台。
