Claims

[Claims for Utility Model Registration] A rail attached to a drawing board that can be tilted between a minimum possible inclination angle of 6x1 and a maximum possible inclination angle of 6x2 with respect to the floor surface, and a rail that is vertically vertical to the drawing board surface. a cursor whose movement is regulated and is movably attached to the rail; a movable rod with one end connected to the cursor and movably disposed on the mouth plate; one side of the movable rod and the rail side; and a magnet which is provided opposite to each other and acts between them, and which biases one of the movable rods in an upward direction perpendicular to the plane of the drawing board by means of magnetic force,
The total weight on the movable rod side is W1 The distance from the center of gravity of the movable rod to the support point of one of the movable rods for the rail is b1 The distance from the center of gravity of the movable rod to the other support point of the movable rod is a
A magnetic guide device for a rail cursor such as a rail type universal parallel ruler, characterized in that the magnitude of the magnetic force between the magnets is set as follows.
