ABSTRACT:
A copying apparatus in which a document inserted into a document feed-in device is circulated through a recirculating path of a recircular automatic document feeder for multi-copying, and a copying paper is fed by cutting a roll paper on the basis of a first document detecting signal of a first detector disposed at the document feed-in device when copying a first sheet, and on the basis of the document length stored in a memory device and a second document detecting signal of a second detector disposed at the recirculating path when copying a second sheet onward, thereby the roll paper can be cut corresponding to the document length at multi-copying without enlarging the recircular automatic document feeder.
