Abstract: The disadvantages derived from a conventional electrophotographic processing machine are that the length of the forward end of the master paper as cut is more than about 600 mm and this increases the amount of loss thereof, thus making the photographic processing expensive. An operation for disposing of the tip of the master paper as wasted paper every time a start switch is depressed requires much labor and renders operability poor. This also requires shifting of the position of the paper tip after cutting upper and lower rolls so that difficulty is involved in carrying out photographic processing simultaneously with such shifting. A roll paper feeding apparatus according to the invention is capable of shortening the tip of the master paper which has to be disposed of as waste at low cost without requiring discharge of the paper tip every time the paper is cut, thus helping the operator.
