    摘要: An electronic measuring apparatus is placed on a drawing or other material on which a measuring object is drawn. The apparatus has a main display of a dot matrix liquid crystal display having a touch sensor. A plurality of points corresponding to the measuring object such as a graphic are entered as specific points. A calculating section calculates lengths of a straight line and a curve, an angle between two straight lines, or regional area of a region based on coordinate data of the respective specified points. The calculated results are shown on the main display. With the arrangement, the respective measurings of the length, angle, regional area, and other measuring object are carried out with ease and high accuracy. Moreover, a variety of processings such as unit conversion and scale factor conversion can be carried out only by entering respective specific data.
