PURPOSE:To make it possible to set an optional Morse code, by making each of plural input termials select one among 3 signals of a logical ''0'' signal, a logical ''1'' signal, and a signal which is inverted between logical ''0'' and ''1''. CONSTITUTION:3 signals of a logical ''1'' signal, a logical ''0'' signal, and a signal which is inverted between logical ''1'' and ''0'', which correspond to one of a point, a line and a stop of Morse codes are generated 100, and it is decided which of 3 signals of a logical ''1'', ''0'' or an inverted one between ''1'' and ''0'' corresponds to each signal of the decision means 101 having plural input terminals connected to one of the signals from said generation means 100, and the Morse codes corresponding to it are output in order in accordance with the sequence of the plural input terminals. And, an optional Morse code can be set by making each one of plural input terminals select one of the signals from the generation means of 3 signals. |
