Abstract

A DEVICE (100) FOR MEASURING LINEAR DISTANCE COMPRISES A LONGITUDINAL RULER BODY (110) BEARING A MAJOR GRADUATION (111), WHICH IS CONSTITUTED OF A PLURALITY OF EVENLY SPACED MARKING LINES (112), AROUND ONE OF THE LONG EDGES ON THE TOP SURFACE AND A BASIC MEASURING UNIT (113) IS DEFINED BY THE DISTANCE IN BETWEEN TWO CONSECUTIVE MARKING LINES (112); A MOVEABLE MEMBER (120) MOUNTED AND SLIDABLE ON THE TOP SURFACE OF THE RULER BODY (110) THAT THE MOVEABLE MEMBER (120) HAS A TRANSPARENT SECTION (121) PARTIALLY COVERING THE MAJOR GRADUATION (111); A SLANTED LINE (130), HAVING A FIRST TIP (131) AND A SECOND TIP (132), LOCATED ON THE TRANSPARENT SECTION (121) WITH THE FIRST TIP (131) CAPABLE OF INTERSECTING THE MARKING LINE (112) AND SPANNING ACROSS THE TRANSPARENT SECTION (121) BY THE WIDTH OF N UNIT OF BASIC MEASURING UNIT (113) THAT LENGTH OF THE SLANTED LINE (130) IS EQUALLY DIVIDED BY A PLURALITY OF SUB-MARKING LINES (133) TO FORM A MINOR GRADUATION (134) COMPOSED OF MULTIPLE SUB-MEASURING UNITS (135) ALONG THE LENGTH OF THE SLANTED LINE (130); A PAIR OF JAWS, NAMELY A FIRST JAW (141) AND A SECOND JAW (142), PERPENDICULARLY EXTENDING OUT FROM THE RULER BODY (110) AND THE MOVEABLE MEMBER (120) RESPECTIVELY; AND A TRANSPARENT STRUCTURE (150), ATTACHED ON THE MOVEABLE MEMBER (120) AND CAPABLE OF TRAVERSING BACK AND FORTH IN RELATIVE TO THE TRANSPARENT SECTION (121), WHICH HAS A LATITUDINAL READING LINE (151) MARKED IN THE MIDDLE OF TWO GUIDE LINES (152A AND 152B) DEFINING WIDTH OF N OR 2N UNITS OF BASIC MEASURING UNIT (113); WHEREIN THE READING LINE (151) HAS SUFFICIENT LENGTH TO INTERSECT WITH THE SLANTED LINE (130) AND N IS AN INTEGER.
