A sheet-stacking apparatus capable of receiving two sheets (120,122) at substantially the same time, which includes a disk unit including four substantially identical rotatable disks (100,102,104,106), each disk including a receiving slot for receiving a portion of a sheet therein. The disk unit is arranged so that two of the four disks receive portions of a first sheet (120) and the remaining two disks receive portions of a second sheet (122). Embodiments also include a bin into which the first sheet and the second sheet are deposited and a selectively extendable separator (110) that separates the first sheet and the second sheet into two separate stacks. The apparatus can also include a tamping mechanism. <IMAGE>
