PURPOSE:To reduce a power consumption by digitally displaying a weight of an object to be measured by means of dots of a plurality of photoconductors. CONSTITUTION:A light producer 4 consists of a light source 5, and a reflecting body 6 reflecting light emitted from the light source 5, and other ends of photo conductors 3 are positioned to the focus of the reflecting body 6. Thus, if the light source 5 is lighted by a power from the light source 7, light thereof enters through the one end of the photo conductor 3 and reaches the other end. Dots 2 corresponding to light passing through the photoconductors 3 enter to display a weight by means of numerical figures. This reduces a power consumption as compared with a device in which lamps generally used are placed in a dot manner, and besides, facilitates maintenance since a light source is only one. |
