ABSTRACT:
A paper cutter has a guide for guiding continuous paper in a lengthwise direction from an inlet portion thereof to an outlet portion thereof. A cutting device disposed downstream of the guide outlet portion partially cuts the continuous paper after it passes through the guide and exits the guide outlet portion, the cutting device partially cutting the continuous paper in a widthwise direction thereof to form two separated cut portions joined at one widthwise end to an uncut portion. At least two projections protrude inwardly of the guide and contact opposite surface of the continuous paper as it passes through the guide. The projections are located in the widthwise direction of the guide so as to concentrate a tensile force applied in the lengthwise direction to the uncut portion of the partially cut continuous paper at the region where the two separate cut portions join the uncut portion to thereby facilitate tearing of the uncut portion of the partially cut continuous paper.
