Abstract

A tape dispenser. The dispenser includes a main body having a connecting board, two side arms at opposite ends of the connecting board respectively, two roll mounts at interior sides of the side arms respectively, four guiding pieces at interior sides of the side arms and below the connecting board and a cutting portion at exterior side of the side arm. A tape roll can be installed at between the side arms by inserting the roll mounts into a central hole of the tape roll. Each roll mount is provided with two stop arms extended substantially parallel to the rotating axis of the tape roll, which has a free end and a block on the exterior side thereof. The blocks are pressed by the tape roll to make the stop arms bent so that they will provide a friction to the tape roll, and a cutter is mounted on the connecting board for cutting a tape of the tape roll off.
