摘要： In a perfecting printing machine, a switch-back mechanism moves backwardly each sheet delivered out of the printing section, and a switching gate provided immediately after the switch-back mechanism selects a first sheet path to return the sheet whose one side has been printed to the printing section and a second sheet path so that the sheet whose both sides have been printed is delivered to the stacker after being moved backwardly by the switch-back mechanism.

摘要： A cleaner for a toner fixing device in an electrophotographic machine or the like. A housing is provided near a pair of fixing rollers, and an endless-belt type felt member is partially disposed in the housing in a folded state. The remaining portion of the felt extends outside of the housing and contacts one of the fixing rollers while the felt is being pressed upon by a drive roller and pressure member. The felt is moved at a slow speed, preferably such that its service life corresponds to one rotation of the felt.

摘要： A mechanism for preventing the skew of a cut paper sheet, for use in a duplex printing machine or a paper reversing mechanism having a switchback mechanism for switching the cut sheet backward from its trailing end by reverse rollers and so on immediately after the cut sheet subjected to the printing at a printing portion is once discharged onto a reverse plate by paper discharge rollers and so on, the mechanism comprising: a plurality of paper guides formed on a surface of the reverse plate of the switchback mechanism so as to limit the lateral movement of the cut sheets of several kinds in the direction of the width thereof, the paper guides being arranged in a manner to correspond respectively to the widths of the cut sheets of several kinds to be discharged onto the reverse plate, the distance between each two paper guides for guiding a respective one of the cut sheets being slightly greater than the width of the corresponding cut sheet, and the paper guide for guiding the wider cut sheet being higher than the paper guide for guiding the narrower cut sheet, whereby each of the cut sheets discharged onto the reverse plate is guided by the corresponding paper guides according to the size of the cut sheet, and is switched backward, thereby preventing the skew of the cut sheet.
摘要翻译：一种用于防止切纸的歪斜的机构，用于双面打印机或纸张反转机构，该双面打印机或纸张反转机构具有用于通过反转辊等将切割的纸从其后端向后方切割的转向机构，在打印部分的打印一旦通过排纸辊等排出到反转板上，该机构包括：形成在转向机构的反转板的表面上的多个纸张引导件，以限制横向移动在其宽度方向上有几种切割片材，纸张导向器以分别对应于要排放到反转板上的几种切割片材的宽度的方式布置，每个纸张之间的距离用于引导相应的一个切割片的引导件略微大于相应的切割片的宽度，以及用于引导较宽的铜 t纸张高于用于引导较窄切割片材的纸张引导件，由此排出到反转板上的每个切割片材根据切割片材的尺寸由相应的纸张引导件引导，并且向后切换，从而防止切片的歪斜。
