Abstract
A medium feeding apparatus includes: a placement mount on which a plurality of media are placed; a transportation mechanism that transports an uppermost medium of the plurality of media placed on the placement mount; a floating-air blowout mechanism that blows out air to float at least the uppermost medium; a suction mechanism that sucks air to cause the uppermost medium floated by the floating-air blowout mechanism blowing out air to be attracted to the transportation mechanism; and a floating-air control unit that causes the floating-air blowout mechanism to start to blow out air while the uppermost medium is being attracted to the transportation mechanism after starting to be transported by the transportation mechanism, so as to float at least a second medium located below the uppermost medium, and causes the floating-air blowout mechanism to stop blowing out air before the second medium starts to be transported by the transportation mechanism.
