Abstract
A paper abutted ruler is provided which can easily be moved on the surface of a surface plate and can simply and accurately be positioned in place. The paper abutted ruler is constructed such that magnet bases rotatably supported at their one ends to a bottom portion of a ruler body and having magnets affixed to lower surfaces of the magnet bases are disposed in the ruler body at opposite-side positions spaced in the ruler longitudinal direction, and the magnet bases are rotated in a direction to tilt upward in interlock with depression of an attraction release button disposed nearly at the center of the ruler body. By depressing the attraction release button to rotate the magnet bases in the direction to tilt upward, the magnet bases are held in a state forming a predetermined angle relative to the surface of the surface plate.
