摘要： A copying apparatus having a prescanning function for obtaining density data to adjust copy parameters includes a correction function which eliminates the data obtained from a portion of a predetermined color, from the density data detected on a prescanning process. The density data can be restricted within a predetermined range. The predetermined range can be easily set by the user.

摘要： An automatic document feeder, made a part of a two-side copying machine which selectably operates in one-side or two-side copying mode of operation, has a pre-feeder which advances a document to be copied next from its original position to a waiting position before reaching a copying position on a document table. A selecting device is further included for controlling the pre-feeder such that the pre-feeder does not function when the second surface of a document is being copied in two-side copying mode of operation.

摘要： A copying machine for copying an original in the form of a double-spread page placed on an original stand or carriage such that the original is accurately divided when copied onto two sheets of paper. The copying machine includes a control device for controlling a copy start position of an original copy operation by a time difference determined between a reference position timing of an original scanning and a sheet feed start timing, and is operable regardless of a selected magnification.
摘要翻译：一种复印机，用于将原稿放置在原稿支架或托架上的双扩展页面的形式复印，使得原稿在复印到两张纸上时被精确分割。复印机包括控制装置，用于通过在原稿扫描的基准位置定时和供纸开始定时之间确定的时间差来控制原稿复印操作的复印开始位置，并且可以与选择的倍率无关地操作。

摘要： An automatic duplex electrophotographic copying machine having a single side copying-related transport passage communicating from a paper supply section through a copying process section to a discharge outlet, a duplex copying-related transport passage located under the single side copying-related transport passage and communicating from the vicinity of the discharge outlet to the vicinity of the paper supply section, an intermediate tray provided in the approximate center of the duplex copying-related transport passage, and a plurality of bins mounted at the discharge outlet to store discharged copy papers, comprises a detector provided at the paper supplying side of the intermediate tray of the duplex copying-related transport passage to detect the picture image density on a copy paper; and a storage bin selection unit for delivering a defective copy paper to a particular bin among the plurality of bins when the detector does not detect any picture image on the copy paper while the copy paper is passing the position of the detector.
摘要翻译：一种自动双面电子照相复印机，其具有从纸张供应部分通过复印处理部分连通到排出口的单面复印相关输送通道，位于单面复印相关输送通道下方的双面复印相关输送通道，从排出口附近到供纸部分附近，设置在双面复印相关传送通道的大致中心的中间托盘以及安装在排出口处以存储排出的复印纸的多个箱包括检测器，设置在双面复印相关传送通道的中间托盘的供纸侧，以检测复印纸上的图像图像浓度; 以及存储箱选择单元，用于当复印纸通过检测器的位置时，当检测器没有检测到复印纸上的任何图像图像时，将有缺陷的复印纸传送到多个箱中的特定仓。
