Claim 9:
10. The output circuit according to claim 1, further comprising
a controller that performs activation and inactivation control of each of the first control device and the second control device such that the positive voltage signal and the negative voltage signal are switched at a predetermined timing and output from the first output terminal,
on/off control of each of the third switch and the fourth switch,
activation and inactivation control of each of the first voltage control circuit and the second voltage control circuit,
control of a voltage supplied to the back gate of the first PMOS transistor switch by the third voltage control circuit,
control of a voltage supplied to the back gate of the first NMOS transistor switch by the fourth voltage control circuit, and
voltage supply/cut off control of each of the positive voltage signal supply circuit and the negative voltage signal supply circuit in conjunction.
