Zusammenfassung:	PURPOSE:To prevent paper powder accumulation and error action of a sensor, by forming a copy feeding system for a copying machine to blow air by force with a fan to the light passage of optical sensors arranged before and behind a feeding roller. CONSTITUTION:Air is blown from a small fan 1 through a blastpipe 3 to the sensors 4 and 4a, by which air is blown at the positions of the luminous emitter and the luminous receiver window of the sensors 4 and 4a, so that paper powder accumulation is prevented, being free from aditional troubles of maintenance.
