Abstract

PURPOSE: To provide a triangular scale which can be easily handled and which permits transferring sizes of different reduced scales in the same plane, by attaching magnetized elements to predetermined portions of a scale body so that the scale can be fixed to a suitable portion of a drawing board.
CONSTITUTION: Each of side surfaces 16aW16c of a graudated member 14 is provided with graduation lines 18 along both of lengthwise edges thereof, as well as slit 20 lengthwise extended at an intermediate portion thereof. A rode type magnetized or magnetic element 22 is fitted in each of the slits 20. When a scale body thus formed is placed on a drawing board, the surface of which being covered with a magnetized material, they adhere closely to each other owing to the magnetic attracting forces of the magnetized materials.
