When a conventional ruler is in use, the ruler slips on the surface of the paper, especially with hard objects such as iron plate or wood. It was getting accurate. The present invention has been devised in order to eliminate the drawbacks. Referring to the drawings, the elastic projection on the back of the ruler catches the paper surface and fixes the ruler, thereby enabling stable use.
Further, the protrusion may be about 1 mm, may be in close contact with the paper surface, and the force for pressing the ruler may be small.
