ABSTRACT:
In a paper feeding apparatus, a paper feeding unit has a paper mounting surface provided with an air-blowing outlet. The paper feeding structure feeds an uppermost sheet of a stack of paper on the paper mounting surface. An air pump supplies air to an air-blowing outlet, a first air-blowing member and a second air-blowing member. The air-blowing outlet is so provided as to blow air to an approximately whole undersurface of the paper stacked on the paper mounting surface. When air is being supplied to the air-blowing outlet, an electronic control unit inhibits the feeding of sheets of paper by the paper feeding unit.
