A paper attachment device is composed of a cap (10), a cup (20), a driving plate (30) and a magnet (40) axially combined in sequence. The cap (10) has a stud movably penetrating through the cup (20) and the driving plate (30) and firmly secured with the magnet (40). The driving plate (30) has multiple resilient arms (30) pressing the cup (20) toward the cap (10), whereby paper can be held between the cup (20) and the cap (10) to make the paper attachment device versatile in usage.
