Abstract

PURPOSE: To simplify the keyboard as well as to enhance the operational performance representing the key switches featuring a low using frequency and the exclusive function to each other by one switch and then selecting plural indicators by operation of the switch.
CONSTITUTION: The keyboard device selects the prescrived function in correspondence to the switch output of each key switch and then reads in the data. Then one unit of integrated switch 3 is provided to the key switch featuring a low using frequency and the plural functions which are exclusive to each other, and furthermore plural units of indicator 4 are provided to correspond to the function of switch 3. The switch output of integrated key switch 5 is applied to counter 9 via start- stop oscillator 8 and then set to the value corresponding to the function set to counter 9. Then the set contents are applied to decoder 10 to be selected and then to be displayed on light emitting diode 6 of corresponding indicator 4.
