An exposure optical system for continuously projecting the image of an original on a document table onto a moving photoreceptor includes a first carriage equipped with document illuminating means moved in synchronism with the photoreceptor and a second carriage moved at half the speed of the first carriage in operative relation thereto by a rotary member and equipped with a reflecting optical system. Paper feed means includes a mechanism for temporarily interrupting the feed of paper and then intermittently sending out the paper to an image transfer station in synchronism with the movement of the photoreceptor. In order to rotate an endless support of the photoreceptor one turn more than the preset number of copies to be made, the switches of a program circuit for controlling the respective operations are opened and closed by a control member rotated in synchronism with the endless support. Air blasts or jets or a suction pick-up head separates the copy paper from the photoreceptor. The endless suport includes a drum having a narrow longitudinal slot, and copy paper is transferred to the photoreceptor with the paper leading edge overlying the recess. The paper is peeled from the receptor by a continuous flow of air directed tangentially at the drum or outward through apertures in the drum to separate the paper leading edge and the complete sheet.
