A feeding device includes a receptacle, a conveyor, an elastic member, and a load adjuster. The receptacle is vertically movable and holds a stack of sheets. The conveyor feeds an uppermost sheet of the stack of sheets on the receptacle in a feeding direction in which a sheet of the stack of sheets is fed. The elastic member biases the receptacle to press the uppermost sheet of the stack of sheets on the receptacle against the conveyor. At least when a height of the stack of sheets on the receptacle is equal to or greater than a given value, the load adjuster applies a reduced magnitude of load downward to the stack of sheets on the receptacle in response to a decrease in the height of the stack of sheets.

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.

A sheet feeding device includes a sheet loader, a first conveyor, a second conveyor, and a guide. The sheet loader is configured to load a sheet bundle including a sheet with a flap. The first conveyor is configured to convey the sheet with the flap loaded on the sheet loader. The second conveyor is disposed adjacent to the first conveyor. The guide is disposed below the flap of the sheet to be conveyed, between the second conveyor and the sheet loader in a sheet conveying direction of the sheet, and is configured to guide the sheet.

A feeder includes a body, a mount portion disposed in the body to support from below part of recording media stacked thereon, a lift that raises the mount portion, a support portion connected to the body to support from below another part of the recording media while the mount portion is raised, the support portion being located higher than a position of a mount surface of the mount portion while the recording media are stacked on the mount portion, a blowing portion that blows air between the recording media stacked on the mount portion, and a transport portion that transports the recording media stacked on the mount portion.

A sheet stacking device include a guide unit and a blower. The guide unit receives a downstream end of a sheet in a sheet conveyance direction and guides the sheet downstream in the sheet conveyance direction. The blower blows air toward the sheet guided by the guide unit. A region of the blower from which the air is blown is changeable in response to a size of the sheet.

A paper feeding apparatus includes a tray, an air blower, a floating detector, and a hardware processor. In the tray, a sheet of paper is loaded. The air blower blows air to the sheet loaded in the tray to float the sheet. The floating detector is provided above the sheet loaded in the tray and detects the floating of the sheet to a predetermined level. The hardware processor causes the air blower to blow the air and determines a basis weight of the sheet loaded in the tray from an air amount that has caused the floating detector to detect the floating of the sheet.
