Bar code displaying device

Abstract

Abstract PURPOSE:To simplify the changing operation to the change of moving goods and a moving destination by changing a voltage to be impressed on respective displaying electrodes corresponding to the position of a car code and displaying a required bar code. CONSTITUTION:A light modulating output is emitted from a transmitting part 10 in accordance with an input set by a setting part 11. This is received by a receiving part 20 and after a photo-electric conversion, this is made into the bar code composed of the voltage values of '0' and '1' and outputted. Since this output is impressed on each displaying electrode 31 of a liquid crystal displaying part 30, each displaying electrode 31 turns into black or white and one bar code is displayed. The width of the displaying electrode 31 is made to corresponding to the minimum width of the bar code. For this reason, when the voltage is successively impressed on the plural number of displaying electrodes 31, a thick line can be displayed and as a result, respective types of the bar codes can be expressed.
