PURPOSE: To send out documents one by one successively from the uppermost one and to easily recognize a copying condition from the number of documents returned to a document receiver by making a first carrying part carry in a batch all documents stacked on a document receiver to a document storage part while inverting them to be watched and waited.

CONSTITUTION: Documents P on the document receiver 1 are stacked while turning the surfaces of the documents upward. While the stacked documents P all are carried in a batch by the first carrying part 2, they are inverted so that the surfaces of the documents is turned downward. Consequently they are carried to the document storage part 3. The documents P carried in the document storage part 3 are sent out one by one successively from the uppermost one by a sheet feeding means 4. In addition, the document P which has been copied is returned to the document receiver 1, therefore a copying condition can be easily recognized only by ascertaining the number of documents P returned to the original receiver 1.
