摘要： A method of and apparatus for synchronously transferring an original and a sheet of copying paper for electrostatic photoduplication. A paper feeding device feeds the sheets of copying paper one at a time until the front edge reaches a predetermined position at a front edge stop. The sheet of copying paper is held at the predetermined position on standby for a period of time, and then a paper transfer device transfers it to move the front edge to an exposure point. At the same time an original placed on a mount is moved from a stopping point in the cycle of movement of the mount to a position in which the leading edge of the original is at an irradiation point optically aligned with the exposure point. The period of time during which the copying paper is fed from the supply, held in the predetermined position, and then moved to the exposure position is equal to the time for moving the mount for the original from a predetermined point along the path of movement of the mount to the irradiation point. Thereafter, the original is moved past the irradiation point synchronously with transfer of the copying paper past the exposure point at a predetermined rate for exposing the copying paper to the image from the original.

摘要翻译： 一种用于同步传送用于静电复印的原稿和一张复印纸的方法和装置。 送纸装置一次一张地输送复印纸，直到前边缘到达前边缘止挡处的预定位置。 复印纸被保持在预定位置待机一段时间，然后纸张传送装置传送它以将前边缘移动到曝光点。 同时，将安装在底座上的原稿从安装件的运动循环中的停止点移动到原稿的前缘处于与曝光点光学对准的照射点的位置。 从供给部保持在预定位置然后移动到曝光位置的复印纸的时间段等于从原稿的安装位置沿着沿着移动路径的预定点移动的时间 安装到照射点。 此后，原稿经过曝光点以预定的速度传送到复印纸，同时被移动通过照射点，从而将复印纸从原稿曝光。
