A sheet feeding apparatus includes: a storage part that stores a sheet, and a feeding part that has a feeding roller for feeding the sheet. The storage part and the feeding part are configured to be integrally inserted/withdrawn into/from an apparatus enclosure. The feeding roller is moved from a feeding position to a retracting position before the storage part and the feeding part are withdrawn from the enclosure.

Sheet feeding apparatus

A sheet feeding apparatus for feeding a sheet includes a first lift tray configured to move up or down in a first lift range and to support a sheet; a sheet feeding unit configured to feed a sheet supported by the first lift tray; and a second lift tray configured to move up or down in a second lift range and to support a sheet in cooperation with the first lift tray. A lowest position in the second lift range is a position above a lowest position in the first lift range, and the second lift range is a range which is narrower than the first lift range.

A sheet stacking apparatus includes a stacking unit on which a sheet bundle is to be stacked, a lifting unit that can lift and lower the stacking unit, and an air blower unit that can apply air to a side face of the sheet bundle via an air blowing port. The stacking unit further includes a stacking face that comes into contact with and holds a lowermost sheet of the sheet bundle, and a support portion that supports a portion of the stacking face near an end portion thereof, and has a face that is not parallel to the stacking face. The support portion includes a ventilating portion that allows air blown out by the air blower unit from a portion of the air blowing port to pass through the ventilating portion, the portion of the air blowing port being below the stacking face.

Method for applying air to sheets stacked on sheet stacking apparatus

A sheet feeding apparatus includes a sheet tray configured to hold sheets, a sheet feeding unit configured to feed sheets from the sheet tray, and a lift unit configured to move the sheet tray up and down. When the type of sheets to be held on the sheet tray is to be changed to another type, the lift unit moves the sheet tray up or down to a sheet holding position set for sheets of the other type. Thus, the position where the sheet tray can hold sheets is changed in accordance with the material or size of the sheets. The largest number, in which sheets can be mounted on the sheet tray, can thereby be changed.
