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.
Claims17
A paper feeding apparatus, comprising:
- a paper tray having a paper mounting surface provided with an air-blowing outlet;
- an air supplying structure configured to supply air to the air-blowing outlet;
- a paper feeder configured to feed an uppermost sheet of a stack of paper on the paper mounting surface;
- an air blower configured to blow air against the upper-end side of a stack of paper;
- and
- a switching structure configured to switch a destination of air supplied from the air supplying structure to either of the air-blowing outlet and the air blower, wherein the air-blowing outlet is configured to blow air against an approximately whole undersurface of the paper stacked on the paper mounting surface.
A paper feeding apparatus, comprising:
- a paper tray having a paper mounting surface provided with an air-blowing outlet;
- a buffer structure which temporarily halts a plurality of stacked papers transported from the paper tray;
- a buffer air blower configured to blow air to an undersurface of paper entering the buffer structure;
- an air supplying structure configured to supply air to the air-blowing outlet and the buffer air blower;
- and
