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 vertically raises or lowers the mount portion, a discharger that transports the sheet-shaped media stacked on the mount portion in order from an upper one of the sheet-shaped media, and first air outlets that blow air to the sheet-shaped media stacked on the mount portion at left and right edges in a feed width of the sheet-shaped media. The mount portion is changeable to a long mount portion capable of receiving long sheet-shaped media by extending an end portion of the mount portion upstream from an unchanged position in a transportation direction of the sheet-shaped media, the end portion corresponding to an upstream end portion in the transportation direction. The sheet-shaped-medium feeder has a second air outlet that blows air to at least one of left and right edges of the long sheet-shaped media stacked on the extended portion of the long mount portion.

A sheet feeding apparatus includes a supporting portion configured to support sheets, a feeding member configured to feed the sheets, an air blower unit configured to blow air to separate the sheets, and a side end regulating member including a regulating surface, an air outlet port through which the air from the air blower unit is blown out, a first restriction member movable to a protruding position and to a retracting position, and a second restriction member disposed downstream of the first restriction member in the feeding direction, the second restriction member being fixed to a position where the second restriction member protrudes inward in the sheet width direction with respect to the regulating surface so as to restrict the excessive floating of the sheets.

An apparatus and a method for singling value documents involve a feeding device adapted to feed a respectively uppermost value document of a stack of value documents to a picking device adapted to pick the value document from the stack. A conveying device is adapted to receive the stack and to convey it relative to the feeding device. A distance sensor is adapted to detect at least one distance of the respectively uppermost value document of the stack received by the conveying device relative to the feeding device and generate at least one corresponding distance sensor signal. A control device is adapted to control the conveying of the stack relative to the feeding device and the location of the feeding device relative to the stack based on the distance sensor signal.
