To provide a continuous paper cutting-off device which reduces motive power for driving roller pairs by optimizing tension applied to paper for cutting off the paper, miniaturizes the device by simplifying a device casing, and also reduces noise by optimizing time required for tearing a paper perforation.

Contact pressurization part to a paper surface of any roller or the whole rollers constituting the roller pairs of two pairs of applying the tension for tearing the paper perforation, is discontinuously arranged at a proper interval, and the total length of the contact pressurization part in the paper width direction is set at 1/2 or less of a paper width.
