Abstract:
1. A sheet cutting device configured to move a second blade toward or away from a first blade and to slide a cutting edge of the second blade along a cutting edge of the first blade to cut a sheet that is fed between the cutting edge of the first blade and the cutting edge of the second blade, the sheet cutting device comprising: a first blade having a first cutting edge; a second blade relatively movable toward and away from the first blade, the second blade having a second cutting edge which opposes the first cutting edge for cutting a sheet when the second blade is moved from an open position away from the first blade and toward the first blade; a slide device connected with the second blade and configured and operable to slide the cutting edge of the second blade along the cutting edge of the first blade for causing the cutting edges to intersect to cut a sheet that is fed between the first and second cutting edges; a blade moving mechanism connected with the second blade and configured and operable to move the second cutting edge of the second blade away from and apart from the first cutting edge of the first blade to move the cutting edges to an open position at which the blades are spaced apart across a direction of the length of the blades for providing space for the sheet to be fed between the cutting edges, and the moving mechanism is also configured and operable to move the second blade to the first blade defining a closed position at which the cutting edges slide along each other for cutting the sheet; a biasing mechanism connected with the second blade and configured to bias the second blade toward the first blade and during the sheet cutting, to cause the second cutting edge of the second blade to slide with respect to the first cutting edge of the first blade for cutting for causing a sheet to be cut between the first and second cutting edges; and a spacing mechanism connected with the second blade and configured and operable to move the second blade away from the first blade against the biasing force of the biasing mechanism during movement of the second blade to the open position.
