A tape dispenser is disclosed in which the tape may be cut within the housing of the dispenser. A roll of the tape is mounted within the housing on a roll holder with a central notch through which a pin extends. A spring in the notch controls the displacement of the roll holder. The tape extends from the roll around a guide roller in relation to which the roll is held in position by the pin. From the guide roller, the tape extends past a blade to a pressure roller which is used to apply the tape to a surface. The blade may be actuated to cut the tape by a pivoting button which protrudes outside the housing, but the blade is held away from the tape by a spring. Between the guide roller and the blade may be mounted a floating roller on a toothed pin. As the tape is rolled onto the surface, the floating roller moves into the housing, bringing the tape to a position in which the blade can cut it without emerging from the housing. The floating roller is on a toothed pin which is mounted between two openings in the housing wall, and at least one tooth in one of these openings engages the toothed pin, causing it to drop into the housing as it turns.
