Abstract
A variable magnification electrophotographic copying apparatus includes an original holder and an original scanning mechanism of the original holder advancing type or of the scanning mirror advancing type. The focus of the image projector lens is adjusted concurrently with the speed of the scanning mirror or original carrier relative to the photosensitive drum speed to adjust the image magnification ratio. Copy paper is withdrawn from a roll thereof and advanced past a cutter through an image transfer station adjacent to the photosensitive drum. The cutter is actuated in response to the position of an indexing member movable along the length of the original and the relative speed of movement of the original or scanning mirror to actuate the cutter so as to cut the copy paper to a length corresponding to the length of the image of the original on the copy paper. The copy paper feed is synchronized with the image scanning so that the leading edge of the image coincides with the leading edge of the copy paper. Switches are actuated by the indexing member carried by the moving original holder or the indexing member of a stationary original holder carries the switches actuated by the scanning mirror carriage and controls the actuation of the cutter.
