Claim 12:
13. The output circuit according to claim 12,
wherein the controller performs
activation and inactivation control of the first control device to the fourth control device,
activation and inactivation control of each of the first voltage control circuit, the second voltage control circuit, the fifth voltage control circuit, and the sixth voltage control circuit, and
on/off control of each of the third switch, the fourth switch, the seventh switch, and the eighth switch, control of a voltage supplied to the back gates of the first PMOS transistor switch and the second PMOS transistor switch by the third voltage control circuit and the seventh voltage control circuit, respectively, control of a voltage supplied to the back gates of the first NMOS transistor switch and the second NMOS transistor switch by the fourth voltage control circuit and the eighth voltage control circuit, respectively, and voltage supply and cut off control of each of the positive voltage signal supply circuit and the negative voltage signal supply circuit in conjunction,
so that one of the positive voltage signal and the negative voltage signal is output from the first output terminal, the other of the positive voltage signal and the negative voltage signal is output from the second output terminal, and the polarity of the voltage signals output from the first output terminal and the second output terminal are switched at a predetermined timing.
