Claims

[Claims for Utility Model Registration] [Yes] A first capacitor whose both ends are connected to an oscillating coil of a bias oscillation circuit;
has second and third terminals, connects the first and second terminals at the first switching position, and connects the first, second and third terminals at the second switching position.
a changeover switch that connects the terminals and connects the second and third terminals at a third switching position;
a second capacitor connected between the terminals;
A bias oscillation switching circuit comprising: a third capacitor connected between one end of the capacitor and a third terminal of the changeover switch; and the other end of the first capacitor connected to the second terminal of the changeover switch.
