A finisher having a stapler for stapling paper sheets sequentially discharged onto a two-sided copy tray of a copier, facsimile machine, printer or similar equipment or onto a bin of a sorter. A paper positioning device included in the finisher has a bin fence and a positioning member. The bin fence is provided on each bin and extends along one side edge of the bin. A positioning member is reciprocatingly movable from a standby position thereof toward the bin fence and back to the standby position. During such a reciprocating motion, the positioning member is repetitively brought into and out of contact with a stack of paper sheets to thereby position the stack. The moving speed of the positioning member is variable.
