Abstract:
1. A paper abutted ruler detachably fixed to a surface plate of a cutter with attraction of a magnet to position paper, which is abutted against an upright surface of the ruler, in a direction perpendicular to a cut line, wherein the ruler includes an attraction button and an attraction release button both disposed in an upper side, a friction sheet attached to a bottom surface thereof for preventing a lateral shift, and a ruler body formed substantially into a rectangular parallelepiped and having an inner space; magnet bases disposed in the inner space of said ruler body at opposite-side positions spaced in the ruler longitudinal direction, said magnet bases being rotatably supported at one ends to said ruler body and having magnets affixed to lower surfaces of said magnet bases; cutouts formed in a bottom portion of said ruler body, said magnets being disposed in said cutouts to face said friction sheet; magnet base rotating means for rotating said magnet bases in a direction to tilt upward; magnet base holding means for holding said magnet base rotating means in a state in which said magnet bases form a predetermined angle relative to the surface of said surface plate; and attracting means for releasing said magnet base rotating means from the state held by said magnet base holding means and tilting said magnet bases downward, thereby causing said magnets to be attracted to said surface plate, and wherein said magnet is attracted to said surface plate through said friction sheet when said attraction button is depressed, and wherein the attraction of said magnet to said surface plate is released when said attraction release button is depressed.
