    摘要： An image forming apparatus has a main body (10) to which is attached a device (12) for cutting paper from a roll and discharging the cut paper through an outlet. The cutting device is selectively shiftable to a feed position where the outlet (110) is in register with a sheet inlet (28) on the main body or to a standby position away from the feed position. The invention also provides a roll paper cutting device for transporting and cutting roll paper having detecting means (270) disposed in the path of transport of documents for detecting a document rear end so as to cut the paper with timing based on the time when the rear end is detected. There is also provided a roll paper cutting device adapted to drive transport rollers with predetermined timing based on the time when the paper travel is detected while all the transport rollers rotate idly in a standby state for paper feeding. Finally, a roll paper cutting device is provided for feeding roll paper to the main body of an image forming apparatus by forwarding the leading end of the paper to feed means (22) disposed in said main body in the paper path to the image forming station, and thereafter transporting the paper onwards by the transport means within the main body.

    摘要翻译： 图像形成装置具有主体（10），其上安装有用于从卷轴切割纸张并通过出口排出切纸的装置（12）。 切割装置可选择性地移动到进给位置，其中出口（110）与主体上的片材入口（28）对准或远离进给位置的待机位置。 本发明还提供一种用于输送和切割卷纸的卷纸切割装置，其具有设置在用于检测文件后端的文件的传送路径中的检测装置（270），以便基于后方的时间 检测到结束。 还提供了一种卷纸切割装置，其适于基于在检测到纸张行进的时间的预定时间驱动输送辊，同时所有的输送辊在备用状态下空转而进行供纸。 最后，提供一种卷纸切割装置，用于通过将纸张的前端通过纸张路径中的设置在所述主体中的进给装置（22）向图像形成装置的主体供给卷纸 ，然后通过主体内的输送装置向前运送纸张。
