A device (12) for changing a sheet pile in a sheet feeder (10) for a sheet treating machine is described. The device (12) comprises a main pile supporting unit (18) having a supporting surface (22) adapted to support a pallet (16) carrying a sheet pile. Furthermore, the device (12) comprises a residual pile supporting unit (24) with a plurality of residual pile bars (28), which can be moved into a sheet pile region (30) when the sheet pile is to be changed. The residual pile bars (28) are then carrying the sheet pile. When in the sheet pile region (30), each of the residual pile bars (28) is movable in a direction substantially orthogonal to the supporting surface (22), wherein the residual pile bars (28) are movable independently from each other. Furthermore, a method for changing the sheet pile in a sheet feeder (10) for a sheet treating machine is explained.

A paper feed device of the present disclosure is provided with a first cassette and a second cassette, a casing, and a support member. The first cassette and the second cassette are arranged side by side in a cassette width direction. The casing has a cassette housing portion. The support member is capable of supporting the first cassette and the second cassette. Each of the first cassette and the second cassette is provided with a pressing portion. In a state where the first cassette and the second cassette are housed, the support member is disposed at a first position retracted upward, while in a state where at least one of the first cassette and the second cassette is pulled out, the support member is pressed downward by the pressing portion so as to be disposed at a second position where the support member is contactable with an installation surface.
