Patent ID: 8439584

Claim:
A paper cutting device for cutting paper having lengthwise edges comprising: a stationary blade; a stationary blade frame for supporting the stationary blade in substantial alignment transverse to the lengthwise edges of the paper when cutting; first and second movable blades each having a blade tip; a movable blade frame for supporting the first and second movable blades on a first support pin and a second support pin, respectively, with the first and second movable blades located in opposite juxtaposition to one another and in a position for movement against the stationary blade when cutting paper so that the first and second movable blades can pivot freely on the support pins to permit the blade tip of the first and second movable blades to move in an overlapping relationship past one another to provide a scissor cutting action against the stationary blade; and a movable blade drive mechanism for causing the first and second movable blades to cut; wherein the position of the stationary blade frame is displaceable relative to the movable blade frame for displacing the position of the stationary blade relative to the position of the first and second movable blades to permit the paper to be accessed for replacement; wherein the movable blade drive mechanism links and drives the first and second movable blades such that one movable blade leads and the other movable blade follows when cutting the paper.
