Document Type and Number:
Japanese Patent JP7249132
Kind Code:
B2
Abstract:
To prevent slippage between a desk surface and a paper surface by using a magnet with a strong magnetic force, and prevent slippage between the paper surface and a straight edge ruler by the magnet and a flexible material, and in particular, to provide the straight edge ruler that allows both large movements/rotations and small movements/rotations.SOLUTION: The straight edge ruler of the present invention has a front inclined portion and a front flat portion on a front surface side, and a back floating portion, a back flat portion, and a back slope portion on the back surface side. The back flat portion is a flexible material in which fine powders of the magnet are dispersed all over the surface, or a solid of the magnet is partially embedded. The back floating portion has a step of 0.1 mm to 1.0 mm from the surface of the back flat portion.SELECTED DRAWING: Figure 1
