Abstract
PURPOSE: To reduce the number of wirings and achieve miniaturization by decording a part of segments both for number displaying and alphabet displaying and displaying the reserved channel in alphabets on the same display tube.
CONSTITUTION: Number displaying 7-segment characters and alphabet displaying 12 segement characters are displayed on a fluorescent display tube 900 and the selection of the characters is accomplished by the signals being applied to the terminals μ, v on a grid terminal board 901. The selection of the contents of the characters is accomplished by the signal being applied to the 12 terminals (a) thru (l) on a plate terminal board 902. Out of the plate terminals, 8 terminals from (a) to (h) are connected to the output terminals corresponding to a decoder 903 of 4 bit input. Hence, the contents of the numbers may be selected by the signals applied to the decoder input A of 4 bits and the contents of the alphabets may be selected by the signals applied to the 4-bit input A and the 4-bit input B.
