Abstract

PURPOSE:To facilitate the use of a scale, by a method wherein a desired division on a reduced and increased scale is indicated in a liquid crystal division indicating part through the working of division selection keys. CONSTITUTION:A liquid crystal division indicating part 2, wherein the division is displayed on a scale 1 by an electric signal, is placed in clear synthetic resin 3, division selection keys 4 are aligned on the upper surface of the scale 1, and a specified division on a reduced and increased scale is displayed in the liquid crystal indicating part 2 through the working of the division section keys. This causes the scale to be conviniently used with drawing up of a plan and other drawings.
