Claim 6:
7. A medium feeding device comprising:
storage means for storing media in a form of a sheet;
delivery means, disposed downstream in a medium delivery direction relative to the media stored in the storage means, for delivering the media individually;
transfer means, disposed above the storage means, for adhering by suction to each of the media stored in the storage means and transferring the media to the delivery means;
fluffing means, disposed beside the media stored in the storage means in a direction intersecting the medium delivery direction, for fluffing an upper-side region of the media in a state of being separated, by blowing air toward a side of the media during a feeding job of the media, wherein the feeding job of the media involves feeding a media into the delivery roller; and
suppression means for suppressing movement of the media toward a delivery means side during air blowing performed by a controller connected to the suppression means and configured to control the fluffing means to blow air toward the side of the media during the feeding job of the media and continue to blow air during a post-feeding period which is a predetermined period after a completion of the feeding job of the media,
wherein the storage means has a stopper wall which is disposed toward a side of the delivery means and is capable of retaining the media stored in the storage means when the fluffing means is not used,
wherein the controller is configured to control the suppressing means to lower a position of a downstream end portion, in the medium delivery direction, of a medium fluffed during the air blowing in the post-feeding period to a position within a retainable region of the stopper wall,
wherein the suppressing means has an air blowing unit that is controlled by the controller to blow air moving downward from an upper side toward the downstream end portion, in the medium delivery direction, of the medium fluffed during the air blowing in the post-feeding period, and the controller is configured to control the suppressing means to lower the position of the downstream end portion of the medium in the medium delivery direction in the post-feeding period, and
wherein the air blower which is controlled by the controller to blows air downward from the upper side of the storage means toward the downstream end portion comprising:
the air blower which is controlled by the controller to blow air diagonally downward from the upper side of the storage means in a direction away from the delivery means, toward the downstream end portion of the medium in the medium delivery direction.
