Title:
SCISSOR TYPE SHEET CUTTING DEVICE
Document Type and Number:
Japanese Patent JP2009006449
Kind Code:
A
Abstract:

To provide a scissor type sheet cutting device capable of maintaining the pressing force between a stationary blade and a movable blade in an appropriate range wherever their crossing sliding position lies between the root and the tip in the blade striation direction.

The scissor type sheet cutting device 1 is configured so that the movable blade 3 is pressed to the stationary blade 2 only with the energizing force of a compression coil spring 42 of a root part energizing means during the period in which the movable blade 3 rotates and the crossing sliding position C to the stationary blade 2 shifts for a prescribed amount toward the tip. The pressing force lowers gradually when the position C separates from the rotational center. After the crossing sliding position C of the two blades 2 and 3 has moved toward the tip for the prescribed amount, the pressing force by a torsion coil spring 45 of a tip energizing means is added to the movable blade 3. Thereafter the movable blade 3 is pressed to the stationary blade 2 by the energizing force of the two energizing means, so that the pressing force of the two blades 2 and 3 is maintained at the prescribed value or above.
