PURPOSE: To output a bipolar signal given the violation of the same phase even if the selection of the output of a signal receiving part is switched to the selection of the output of another signal receiving part in respect of a signal receiving selection device in which the signal receiving part receives and outputs the bipolar signal given the violation, and the signal receiving part receives and outputs the signal of the same phase as the bipolar signal or the signal of the inverted phase, and the output of the signal receiving part or the output of the signal receiving part is selected and outputted by a selecting part.
CONSTITUTION: The signal receiving part 2 is provided with an inverting part 5 to invert the phase of the received bipolar signal and a selector part 6 to input, select, and output the bipolar signal whose phase is inverted by the inverting part 5, and the selecting part 3 is provided with a phase comparator 7 to compare the phase of the output signal of the selector part 6 of the signal receiving part 2 with the phase of the output signal of the signal receiving part 1, and send a selection signal for the selector 6 to select and output the signal whose phase coincides with the phase of the output signal of the signal receiving part 1.
