<p>Disclosed herein is a cutting ruler. According to the invention, when a section of an object to be cut is aligned with a cutting groove and a cutting unit is moved, a blade of the cutting unit is guided along a guide rail in a straight line without movement, thus cutting the object. Therefore, it is possible to cut an object precisely and straight, and a cutting operation can be rapidly and conveniently carried out without damaging the original object. Further, when the cutting operation has been completed, a support surface is not scratched, thus providing a clean working environment. Since the blade of the cutting unit is not exposed during the cutting operation, there is no danger of injury, and thus, the cutting ruler of the invention is very safe. Further, a perforated line may be easily formed on an object using a rotary cutting unit.</p> |
