A sheet feeding apparatus for feeding sheets is provided with a delivery roller for delivering sheets on a stack tray, and an air blower mechanism for blowing air to the sheets on the stack tray, and selects to execute one of first operation for blowing air to the sheets to handle the sheets on the stack tray in a state in which the delivery roller is brought into contact with the sheets stacked on the stack tray, and second operation for blowing air to the sheets on the stack tray to handle the sheets in a state in which the delivery roller is retracted from the sheets stacked on the stack tray.

A sheet feeding apparatus includes a sheet support portion supporting a sheet or sheets, a sheet feeding unit for performing a sheet feeding operation, an air sheet-separation unit for performing an air blowing operation, and a control unit for performing sheet feeding control to perform the sheet feeding operation by using the sheet feeding unit, in a state where the air blowing operation is in a stopped state, after the air blowing operation is performed by the air sheet-separation unit and the air blowing operation is stopped. In the sheet feeding control, after performing the air blowing operation, the control unit performs the air blowing operation again when performing the sheet feeding operation by using the sheet feeding unit on sheets of a set number of sheets set in advance based on an attribute of the sheet supported on the sheet support portion.

A device for reducing rotation of an article during singulation of a stack of articles is disclosed. The device may include a torsion element, a rotatable member configured to rotate about an elongated axis of the torsion element between a first position and a second position, and a revolving member coupled to the rotatable member. An outer surface of the revolving member contacts a drive belt in the first position and an article in the second position. The torsion element exerts torque on the rotatable member when it moves from the first position towards the second position. The torque causes the outer surface of the revolving member to apply a frictional force to the article, thereby minimizing rotation of the article. Systems and methods of singulating articles are also disclosed.

A medium discharge unit that discharges a medium subjected to recording by a recording unit, a placement unit at which the medium discharged by the medium discharge unit is placed, the placement unit being inclined with a downstream side in a discharge direction in which the medium is discharged being positioned, in a vertical direction, above an upstream side in the discharge direction, an air blowing unit that blows air from above toward the medium discharged from the medium discharge unit, and a control unit that controls the air blowing unit are included. The control unit can attenuate air blowing by the air blowing unit, based on information of an interval between a preceding medium and a following medium that are to be discharged from a discharge position of the medium discharge unit to the placement unit, when the preceding medium is discharged from the discharge position.
