摘要： An electronic copying machine according to the present invention has a copying unit for forming images on paper sheets and then discharging them, and a resupply unit for resupplying the same paper sheets to the copying unit, for other images to be formed on the sheets. The resupply unit has a pull-out unit which can readily removed therefrom, and the copying unit has a jam sensor for detecting that a paper sheet is jammed between the copying unit and the pull-out unit. When the jam sensor detects the jamming of a paper sheet when the copying machine is in overlap copying mode, the jammed paper sheet is forcedly discharged from the resupply unit. Alternatively, when the jam sensor detects the jamming of a paper sheet when the copying machine is in double-sided copying mode, the jammed paper sheet is forcedly pulled into the resupply unit.
摘要翻译：根据本发明的电子复印机具有用于在纸张上形成图像然后放电的复印单元，以及用于将相同的纸张重新供给到复印单元的再供给单元，用于在纸张上形成的其它图像。再补充单元具有可以容易地从其中移除的拉出单元，并且复印单元具有用于检测纸张在复印单元和拉出单元之间卡住的卡纸传感器。当复印机处于重叠复印模式时，当卡纸传感器检测到纸张卡纸时，卡纸被强制从补给单元排出。或者，当复印机处于双面复印模式时，当卡纸传感器检测到纸张卡纸时，被卡住的纸张被强制地拉入补给单元。

摘要： An electronic copying machine of the shell-type with a main body having an upper unit and a lower unit. The upper unit is provided with an original tray on which originals to be copied after being automatically fed to an exposure table are disposed. The upper unit is connected to the lower unit by a connecting part, in such a way that the upper unit can be swung by a predetermined angle in relation to the lower unit. The original tray is slanted, with its front end being made lower than its back end, to thereby form an elevation angle equal to or larger than the predetermined angle, in relation to the horizontal face. Even if the upper unit is swung by the predetermined angle, in relation to the lower unit, to expose the inside of the copying machine when a paper jamming trouble occurs the original tray is not slanted until its back end is made lower than the horizontal face, thus preventing the originals from sliding down from the back end of said original tray.
摘要翻译：一种壳型电子复印机，其主体具有上单元和下单元。上部单元设置有原始托盘，其上被自动馈送到曝光台后要被复制的原稿被放置。上部单元通过连接部分连接到下部单元，使得上部单元可相对于下部单元摆动预定角度。原始托盘是倾斜的，其前端被制成低于其后端，从而相对于水平面形成等于或大于预定角度的仰角。即使上部单元相对于下部单元摆动预定角度，当出现卡纸故障时，也可以使复印机的内部露出，直到其后端低于水平面，从而防止原稿从原始托盘的后端向下滑动。
