A volute spring pushes the paper roll for keeping the outer surface of the paper roll to touch a barrel which contains the paper roll. The surface of barrel has the prominent lines for decreasing the friction between the outer surface of the paper roll and the inner surface of the barrel. The barrel is configured in an outer casing of a pen, and the barrel and the outer casing have a first opening and a second opening separately. The first opening and the second opening is correspondent to each other. One side of the second opening is an inward bevel edge which extends into the first opening and interferes with the outer tier of the paper roll. The outer end of the paper roll can be pushed out of the first opening and the second opening against the inward bevel edge.
