Claim 0:
1. A medium feeding device comprising:
a tray that stores media in a form of a sheet;
a delivery roller that is disposed downstream in a medium delivery direction relative to the media stored in the tray and that delivers the media individually;
a suction device that is disposed above the tray and that adheres by suction to each of the media stored in the tray and transfers the media to the delivery roller;
a fluffing blower that is disposed beside the media stored in the tray in a direction intersecting the medium delivery direction, the fluffing blower 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
a controller that is configured to suppress movement of the media toward a delivery roller side during air blowing performed by being configured to control the fluffing blower 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 tray has a stopper wall which is disposed toward a side of the delivery roller and is capable of retaining the media stored in the tray when the fluffing blower is not used,
wherein the controller is further configured 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 medium feeding device further comprises an air blower which is controlled by the controller to blows air moving downward from an upper side of the tray 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 lowers the position of the downstream end portion of the medium in the medium delivery direction during 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 tray 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 tray in a direction away from the delivery roller, toward the downstream end portion of the medium in the medium delivery direction.
