のギザギザ部を有する特許請求の範囲第１項記載
の縮尺図面用測定器。[Claims for Utility Model Registration] (1) In a measuring device for scale drawings that converts and displays the distance of a measurement section of a scale drawing into actual dimensions according to the scale factor, the distance traveled is calculated by driving along the route of said measurement section. a traveling wheel that rotates at a corresponding rotational speed; a decelerating rotation means that rotates at a predetermined reduction ratio based on the rotation of the traveling wheel; and an original size distance obtained by dividing the traveling distance of the traveling wheel by the scale factor. A measuring instrument for scaled drawings, characterized in that the scale drawing measuring instrument is equipped with an original size display means for displaying at a position corresponding to the rotation angle of the deceleration rotation means. (2) The measuring instrument for scale drawings according to claim 1, wherein the running wheel has a jagged portion on its outer peripheral surface to prevent slipping.
