ABSTRACT:
A device for sensing feeding of copying papers, which may promptly detect paper jamming and misfeeding occurring at a paper feed route of a copying apparatus, such as a laser printer or a copier, thereby preventing pollution by toner or damage of the apparatus. To this end, the device comprises a ratatable actuator of a circular disk shape having a plurality of slits, a first sensor disposed outwardly of the actuator to sense a paper feed condition, and a second sensor disposed outwardly of the actuator to sense the presence and absence of the paper, whereby both the actual feed state and feed distance of the paper may be promptly detected during feeding of the papers.
