Abstract
PURPOSE: To materialize a key input unit which can give priority to only one key out of more than two keys which are operated at the same time, and suppresses intputs of the other keys, by arranging that the unit stores a discrimination signal corresponding to a timing at its register, and, when the register stores the signal, the successive inputs to the register are suppressed.
