Abstract

PURPOSE:To facilitate the calibration of a scale by providing a frame part to a jig equipped detachably to an upper board rotating on the same axial center with a horizontal protractor, and making adjustments in the axial center direction and tangent direction with a bernier in contact in the frame. CONSTITUTION:To an upper board 10 rotating on the same axial center with a horizontal protractor, a correcting jig device body 14 is fitted through fitting holes 15, 15-. A frame part 16 surround both the edge parts of a bernier 11 with a prescribed gap. One frame part 16 is moved in the axial center direction with screws 17 and 17 or in the tangent direction with screws 18 and 18, thus adjusting the bernier 11. Further, an extrusion adjustment piece 19 is adjusted with a sccrew 23 to move the bernier 11 in an external circumference direction. The other frame part 16 has a screw 29 inserted into the screw hole 28 of its supporting piece 27 to fix the horizontal protractor. Engagement projections 30 and 30 engage with the upper board 10. The jig body 14 is fitted and after the bernier 11 is loosened with the screw 13, the screws 17, 18 and 23 are adjusted to adjust the scale. Thus, the bernier scale is adjusted rapidly and accurately.
