Patent ID: 11685622

Abstract:
A medium feeding device includes a storage unit that stores media in a form of a sheet, a delivery unit that is disposed downstream in a medium delivery direction relative to the media stored in the storage unit and that delivers the media individually, a transfer unit that is disposed above the storage unit and that sticks by suction to each of the media stored in the storage unit and transfers the media to the delivery unit individually, and a fluffing unit that is disposed beside the media stored in the storage unit in a direction intersecting the medium delivery direction. The fluffing unit fluffs an upper-side region of the media in a state of being separated by blowing air toward a side of the media. The medium feeding device further includes plural position detection units that are arranged in a region that is on the delivery unit side relative to a position of a downstream end portion, in the medium delivery direction, of each of the media stored in the storage unit and that does not reach a contact portion where the delivery unit comes into contact with the media. The position detection units are arranged at an interval in a width direction of the media intersecting the medium delivery direction. The position detection units detect a position of the downstream end portion, in the medium delivery direction, of each of the media.
