ABSTRACT:
A picture printing apparatus has a supply magazine section which accommodates a plurality of roll papers. The roll papers are carried by an endless belt which successively positions the roll papers to be fed to the exposure section of the printing apparatus. The end of a roll is detected to cause a new roll to be brought into the feeding position. At the same time, the end of the roll just detected is clamped so that the beginning of the next roll can be connected to it. Once the connection is accomplished, the paper is released so that the newly positioned roll paper can be continuously fed to the exposure section. An exhausted roll can be replaced on the endless belt without interruption of the printing operation.
