A sheet feeding device includes a sheet loader, a sheet feeder, and an end fence. The sheet loader is configured to load a sheet bundle including sheets. The sheet feeder is configured to feed an uppermost sheet of the sheet bundle loaded on the sheet loader. The end fence is disposed movable in a sheet feeding direction of the uppermost sheet and is configured to contact a trailing end of the sheet bundle in the sheet feeding direction to regulate a position of the trailing end of the sheet bundle. The end fence includes an elastic body configured to contact the trailing end of the sheet bundle at a portion other than at least an upper portion of the end fence.

A sheet-shaped-medium feeder includes a housing, a mount portion that is disposed to be vertically movable in the housing and that receives sheet-shaped media, a lift that includes line members to vertically raise or lower the mount portion by hanging the mount portion with the line members, and a discharger that transports the sheet-shaped media stacked on the mount portion. The mount portion is changeable to a long mount portion capable of receiving long sheet-shaped media by extending, further upstream in a transportation direction of the sheet-shaped media, an upstream end portion of the mount portion in the transportation direction of the sheet-shaped media. The lift has the line members attached at a portion of the long mount portion corresponding to an unchanged portion of the mount portion, and at a portion of the long mount portion corresponding to an extended portion of the mount portion.

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 adheres by suction to each of the media stored in the storage unit and transfers the media to the delivery unit, 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 during a feeding job of the media and during a post-feeding period that is a predetermined period after completion of the feeding job. The medium feeding device further includes a suppression unit that suppresses movement of the media toward the delivery unit side during air blowing performed by the fluffing unit in the post-feeding period.

The sheet conveyance apparatus includes an apparatus body including a conveyance portion, and a door portion pivotally supported around a pivot axis disposed in a lower portion of the apparatus body. The apparatus body includes a holding member including a first holding portion used to lift the apparatus body, and the holding member is disposed inside a width of the door portion in an axis direction of the pivot axis. The holding member includes a first engaging portion and a second engaging portion disposed on the pivot axis. The door portion includes a first engaged portion configured to engage with the first engaging portion, and a second engaged portion configured to engage with the second engaging portion. The door portion is pivotably supported around the first engaging portion and the second engaging portion with respect to the holding member.
