Claims

[Claims for Utility Model Registration] (1) A box-shaped casing that opens upward and a planar shape that is smaller than the planar shape of the inside of this casing, and that is arranged in the paper feed direction within the casing. and a movable bottom plate that is swingably arranged so that the leading end in the paper feeding direction moves up and down, and the minimum size of paper sheets that can be accommodated as determined by the planar shape of this movable bottom plate. A paper feeder having a side plate and a back plate disposed at the bottom of the casing so as to be freely repositionable between positions of the maximum size of sheets that can be accommodated, which are regulated by the position and the planar shape of the inside of the casing. In the cassette, an auxiliary bag is disposed at an intermediate position between the leading end and the rear end of the movable bottom plate in the paper feeding direction so as to suppress the trailing edge of the paper sheets and to allow the movable bottom plate to swing. A paper feed cassette characterized in that a plate is provided in a casing so that it can be freely attached to and removed from the casing. (2) The paper feed cassette according to claim 1, wherein the auxiliary back plate is positioned by engaging with the movable bottom plate. (3) The paper feed cassette according to claim 1, wherein the auxiliary back plate is positioned by engaging with the side plate.
