Abstract
PURPOSE:To achieve a higher efficiency in a drafting job eliminating inconvenience of a fixed graduation scale, by inputting a data from an input device to display a desired unit scale. CONSTITUTION:When centimeter (or inch) unit graduation is required, a specification data is inputted into a display control section 5 by opening a switch 12 (or 13) of an input section 4. The control section 5 makes active an AND gate 16 only with a decoder circuit 17 connected to a light emitting diode 10 corresponding to a n-th (n; odd or even number) or skipped at interval of inches display to point 2 energize the diode 10. Thus, the display points 2 are made ready for display every other one (or only the display points 2 done selectively) and a centimeter (or inch) graduation is displayed. This enables measurement by various units in the setting of the length of a segment and others without preparing various scales or performing calculation in varied graduation units.
